5. OPTICAL FIBRE SYSTEMS

5.1

Overhead

5.1.1

All Dielectric Self-Supporting (ADSS) Cable:

All ETSA Utilities owned optical fibre cable must comply with the ETSA

Utilities specifications and be marked in accordance with AS2211. In orderto minimize the visual impact of the optical fibre cable the cable colour may

be dark grey or black. Other colours are not permitted.

The cable must be water blocked and have a high-density polyethylene

outer sheath. Single mode fibre is to be used as standard construction.

Standard sizes and their uses are:

12 core (No longer installed by ETSA Utilities)

24 core (No longer installed by ETSA Utilities but used by thirdparties)



72 core (Currently installed)

144 core (Currently installed in high density areas and for trunk

lines in rural centres.)

No signs are required at the pole top.

The final installed cable tension should not exceed 50% of the Ultimate

Tensile strength (UTS) of the cable. To further minimise the visual impactof the optical fibre cable it must be sagged to match the sag of adjacent low

voltage conductors.

ADSS short span optical fibre cable may be used where the span length

does not exceed 150m. Where span lengths exceed 150m, Long Span ADSS

(LSADSS) must be used.

Refer to the appropriate section of the Telecommunication Equipment

Construction drawings included in Appendices A, B & C for the approved

constructions for ADSS and LSADSS.

In its final condition, ADSS cable must not be bent in excess of

manufacturers specifications.


10/55




Cable Suspension:

Where open wire low voltage (LV) exists, the optical fibre cable shall be

generally located between the pole and the neutral conductor as detailed in

Appendix-A. The cable is suspended from the cross arm using a clamp as

detailed in Appendix-A. The cable may be supported from the pole only

where there is restricted clearance between the pole and the neutral. Thisarrangement allows for movement of the optical fibre cable in the vertical

plane. Cable may be strung, under tension through the specified support

clamp. In this configuration, it required that the neoprene inserts be

removed and the cable is not being allowed to sag more than 2m in the span.

Where no LV exists, the suspension clamp as shown in Appendix-A must be

used. Note that this clamp is not suitable for stringing.

The optical fibre cable must not be erected above or adjacent to HV

conductors without specific approval from the NSM.

The termination of ADSS cable is NOT permitted in any direction of (4")

100mm stobie poles. Overhead double spanning is not permitted. Balanced

tensions must always occur on 100mm poles except where a 24 core service

is required.

Refer to section 4.1.4 Fibre Management System & Pits for more details

11/55




5.1.2Cables Owned by Third Parties (e.g. Telecommunications Carriers)

The cable specifications are entirely up to the owner of the cable and must

be supplied to ETSA Utilities for pole load/strain calculations to be

undertaken. Construction detailed route drawings must be submitted to

ETSA Utilities for pole strength assessments to be undertaken at the cost of

the third party. This may be followed by Make Ready works completed by

ETSA Utilities at the cost of the third party before any stringing can occur.

In designing of third party Telco assets which are to be constructed on

ETSA Utilities asset, the design parameter must allow for tension

variations (e.g. conductor sagging) which result from changes due to

weather condition and existing ETSA Utilities span lengths and tensions.

The minimum clearance between LV conductor and Telco cable of 600mm

applies to span up to 50m. Minimum clearance for longer spans will be

determined by ETSA Utilities.

Stringing of non-ETSA Utilities telecommunications cable must be in the

carrier window on the pole which is an area between 1.4m and 1.8m below

the LV conductor level on the road side of the pole, unless passing a pole

mounted transformer. Refer to Appendix-A for more detail. The position

within this window will be determined by ETSA Utilities for each applicant.

Where the preferred position (1.8m below LV) is already occupied or is

technically unsuitable, e.g. Due to truck clearances, then ETSA Utilities will

attempt to provide an alternative attachment position, usually 1.5m below

the cross-arm.

All completed works drawings must be returned to ETSA Utilities within 30days of construction for updating of Facilities Access records, with clear

details of the route and number of poles accessed.

Where non-ETSA Utilities overhead telecommunication cable needs to

cross a high load corridor or railway/tramline then it must be placed

underground. Where non-ETSA Utilities overhead telecommunication cable

needs to cross roads then clearances to the carriageway specified in the

Electricity Act 1996 and Electricity (General) Regulations, Schedule 2,

Table 3 (refer Appendix-D, Table 3 - for GUIDE ONLY), must be

achieved without raising attachment points on the adjacent poles or place

the cable underground.

Refer Appendix D, Table 3 (for GUIDE ONLY) for the clearance distances

for aerial service lines and other cable systems. This table is extracted from

the Electricity (General) Regulations 1997, Schedule 2 Requirements for

aerial lines. For current and accurate details refer to latest revision and

publication of Electricity (General) Regulations 1997.


12/55




Attachment to the poles must be by pole clamps as shown in the following

drawings, e.g. Appendix A1 sheet 10.2 and not by attachments requiring

extra holes to be drilled into the steel sides or concrete of the ETSA Utilities

poles.

In some circumstances Make Ready works may be required prior tostringing cable without a catenary which will be determined by ETSA

Utilities as part of assessing the FAA application. If the work is planned by

ETSA Utilities, such as pole replacements for maintenance purposes, the

applicant will need to wait until the work is completed by ETSA Utilities or

select an alternate route.

Where work is required to make room in the carrier window e.g. by

removing redundant equipment, this will be at the applicants cost. If the

redundant equipment is electrical or associated with electrical equipment

e.g. street light switch wires, ETSA Utilities will determine if it can be

removed safely by the applicant as part of stringing or not. If the equipment

is redundant telecommunications assets then ETSA Utilities will specify

removal as part of the applicants stringing works.

NB: If removing Optus Pay TV cable, in all instances the catenary must not

be removed or obstructed.

When stringing at the 1.5m below LV height, the first Third Party to be

given access will remove any existing Optus Pay TV cable (but leave the

catenary) and install a short cross arm, at their cost, as shown in Appendix

A1 sheet 8. The third Party will be given a consistent position on the crossarm next to the pole or at the outer end of the arm. Removal of any waste

material is the responsibility of the Third Party.

Before stringing at the 1.5m below LV height, the stobie pole strength

visual inspection (i.e. rust at base, cracks, bend or any other damages)

should be carried out and referred to ETSA Utilities for assessment of

reduction of pole strength. Refer to Appendix-E E1-Sht 1 as a GUIDE

ONLYfor typical stobie pole loading.

If any existing O/H arrangement is outside the parameters covered in

Appendix-E such as other third party assets already installed (e.g. Pay TV orPilot cables) then this must be forwarded to the ETSA UtilitiesFacilities

Access & Projects Coordinator for further assessment. ETSA Utilities-

Manager Network Assets approval and sign off is required before any route

design is finalised and any work can commence.

For facilities access applications, the single point of contact is Darren Smith

Facilities Access and Projects Coordinator (08) 8404 5399 or if

unavailable Peter Dean Manager Network Projects (08) 8404 5064.


13/55




5.1.3Optical Ground Wire / Neutral (ETSA Utilities Assets)

All optical fibre cable must comply with the ETSA Utilities specifications.

In summary, the OPGW optical fibre cable is of loose tube construction

with 12 fibres per tube and a GRP core. The cable has a solid metal sheath

surrounding the optical fibre tubes. The sheath is surrounded by strands of

the electrical conductor. Fibres are single mode.



constructions for OPGW.


12 core Radial spurs

60 core Radial spurs

Signs must be installed at the pole top adjacent the OPGW and OPGN

conductor to identify the cable as containing optical fibres.

The final installed cable tension should not exceed 20% of the Ultimate

Tensile strength (UTS) of the cable.

In its final condition, OPGW cable may not be bent in a radius less than 10

times the diameter of the cable. During stringing, the cable may be

temporarily bent up to 20 times the diameter of the cable, provided the bend

is not supported by any sharp edge.

Cable Suspension:

In all cases, the OPGW cable is installed above the high voltage cable and

OPGN may be installed as a LV neutral or as a CMEN conductor.

5.1.4Fibre Management Systems and Pits

Fibre Management Systems:

All fibre management systems FIST/FOSC/etc shall be labelled in

accordance with Appendix B-3. In all metropolitan areas ETSA Utilities

shall utilise FIST enclosures for jointing. All fibre management systemlocation and numbering shall be included on all construction drawings.

The arrangement of cable and fittings within pits must comply with the

requirements of ETSA Utilities specifications and Appendix C1 for third

party assets. Especially the notes on sheet 3 where there are 2 existing 288

core fibres (or equivalent) in a P9 pit. Where space is critical and a variation

is required seek specific Facilities Access approval.


14/55




Cable Pits:

All fibre optic cable will be installed in line with Appendix-C with

sufficient access points to enable expansion and repair of the network.

Generally this will include the following.

Cable Pits Metropolitan:Pits shall be located at intervals of not less than 2500m and not more

frequently than 2000m unless required for immediate access. Cable

management systems such as FIST/FOSC enclosures shall be installed

only where required for immediate access or where required for

joining cables during construction.

P9 pits will be used in these areas. Additional cable of between 80-

100m shall be installed in all pits.

Cable Pits CBD Area:

Pits shall be located at intervals of no less than 700m. P9 pits shall be

used in these areas to contain additional cables and FIST/FOSC cable

arrangement systems. Additional cable of between 30-100m shall be

installed in all pits. Unless exceptional circumstances exist, additional

cable SHALL NOT be stored in the CBD manholes.

Cable Pits Rural Area:

P9 Pits will be used in rural areas. Additional cable of between 80 &

100m shall be stored in cable pit.

Pit Numbering:All pits shall be numbered in accordance with Appendix B-2. Pit numbers

shall be included on all constructions.

Repair Jointing:

Jointing will only occur in pits.

Line Pole Arrangement:

Arrangement details are not required to be resolved for line poles (i.e. Poles

with less than 20% deviation) during the design process.


15/55

5.2.2Ducts/Conduits

Where optical fibre cables are to be installed in ducts or conduits, the fibre

cable shall be encased inside 32mm polyethylene sub-duct.

Where fibre is to be installed in spare duct/conduit, a sub-duct is required.Fibre (in sub-duct) may be installed in the same duct/conduit as existing LV

power cables (but not in ducts with HV power cables) where physically

practical (e.g. few bends) if no Telco ducts are present.



constructions for Underground Optical fibre cable.

In its final condition, ADSS cable must not be bent in excess of

manufacturers specifications.

Where non-ETSA Utilities fibre/cable is installed in ETSA Utilities ducts or

pits this requires prior approval by ETSA Utilities and falls under a

Facilities Access agreement.

The work must comply with the following specifications for labelling and

trenching. Third Party fibre must be in sub ducts which must be labelled.

This applies whether in telecommunications ducts or electricity ducts.

Where an observer is required to open and work in ETSA Utilities

telecommunications pits as part of the access approval this will be at the

applicants cost.


16/55


5.2.3Labelling (Third Party Fibre Cable)

The optical fibre cable must be labelled in accordance with AS/NZS2211.1.

5.2.4

Break out enclosures (ETSA Utilities Assets)

Break out enclosures shall be installed adjacent to the site and as requiredby the network design. Enclosures shall be installed in accordance with

Appendix-C, C1-Sht 1 (pit mounted) or Appendix-C, C1-Sht 2 (wall

mounted). Sufficient spare cable (80-100m) must be provided in both the

incoming and outgoing cables so that the enclosures may be removed and

placed within a clean environment during splicing. This is also to allow for

repair and expansion of the network.

5.2.5Trenching

Reinstatement shall be consistent with good industry practices. Compaction

to ensure that subsidence does not occur is required in the metropolitan area.

5.3 Building Entry for ETSA Utilities Fibre

In general, ETSA Utilities will install telecommunications main backbone and

alternative backbone (if requested) to an equipment rack installed in the main

equipment room. Where the connection to the ETSA Utilities network is directly

to a main core network fibre, ETSA Utilities will utilise a FIST enclosure in a pit

outside the premises. Where the connection is to a radial spur the connection will

be direct to the equipment rack, with 20m of spare fibre installed if possible. The

spare fibre shall be placed in a suitable location inside the building. Design and

installation of telecommunications cabling and equipment shall be in accordance

with AS3084 Telecommunications Installations Telecommunications

pathways and spaces for commercial buildings.Specific references are provided

below:

5.3.1Backbone Pathways

Installation will comply with;

Refer section 3 of AS3084 Telecommunications Installations

Telecommunications pathways and spaces for commercial buildings.

5.3.2Equipment Room




5.3.3

Building Entry points




Installations may be made in conduits containing LV power cables where

the fibre cable uses a sub duct (refer 4.2.2).

5.3.4

Access to ETSA Utilities equipmentWhere the building is not owned by the customer, written permission and an

access agreement must be provided to ETSA Utilities by the building owner

prior to installation of ETSA Utilities cabling or equipment.


18/55




5.4 Substation Entries for ETSA Utilities Fibre

All substation sites shall be classed as Edge, Hub or Point of Presence (POP)

sites. Entry to Edge, Hub and POP sites will require duplicate diverse entry.

Where the Hub site is not required to be established immediately suitable spare

fibre may be temporarily on site but not terminable. Where a POP site is not

required to be established immediately all fibre entry must be terminated in the

first installation.

Substation property access by third parties for installation of telecommunications

equipment requires an application for a site licence under the Facilities Access

Agreement. The site licence will impose strict conditions regarding access to

substations by third parties and will require a safety observer unless the third

party is an endorsed contractor. Such access will also be conditional on ETSA

Utilities requirements at that time. Wherever possible the third parties equipment

should be installed outside of the earth grid area of the substation. This would

usually entail use of part of the landscaped area around the outside of the securityfence and enable third party access to equipment without an ETSA Utilities

observer.

All Third party huts or cabinets when installed will require a separate electricity

supply from the street via the supply connection process.

Where equipment is inside the substation as other options are not practicable,

ETSA Utilities will specify the construction and access details. If access requires

entry into the substation area then an Access Permit and observer is required for

each instance at the applicants cost. Processing of access applications by ETSA

Utilities NOC usually takes 10 days.

Fibre entering a substation to a ETSA Telecommunications hut which has third

party racks, is the property of ETSA Utilities from the pit to the hut.

5.5

Performance Standards

5.5.1Dielectric Loss (ETSA Utilities Assets)

All cables will be subjected to an insertion loss test. 1.5dB/km is the

maximum permissible insertion loss. A time domain reflectometry based

test is not required.

5.5.2Wind Loading

Where the fibre optic cable span exceeds 150m or on poles with less than 3

conductors, wind loading effects on the Stobie poles must be considered.

Wind loading effect is to be determined in accordance with TS107 (Over

head line design) where non-ETSA Utilities fibre is to be installed. This

issue would require Make Ready works at the applicants cost.

5.5.3Minimum Life (ETSA Utilities Assets)

All fibre cables must be installed in a manner consistent with a 25 year assetlife.

7.

MICROWAVE SYSTEMS

Still to be completed

8. SWITCHING EQUIPMENT (ETSA UTILITIES ASSETS)

8.1 Environmental Conditions

Switching equipment shall be located in an environment suitable for the reliable

operation of the equipment. Generally a suitable environment will be achieved for

access nodes by locating the equipment within a ceramic walled building without

air conditioning.

Climate control for core switching sites shall comprise air conditioning. Air

conditioning shall be reverse cycle sized to provide a maximum temperature of nomore than 27C in an ambient temperature of 45C. Core sites shall include

remote alarming for temperature > 31C.

8.2 Electromagnetic Interference

Switching equipment with copper cable shall be located in a separate room from

the 11kV and higher switching equipment. Typically this will be achieved by

locating equipment in a separate Substation Control Room or in a separate

building.

8.3

Standard Equipment

8.3.1Ethernet Switches

Standard Ethernet switching equipment shall include as a minimum, the

following:

Dual power supplies for chassis power supply diversity.

Diversity of ring distribution cards for provision of diversity in feeds

for fibre optic (Gig bit Ethernet) core and service rings.

APPENDIX B: ETSA UTILITIES ASSETS

B-1 - Fibre Cable Numbering:

Fibre Cable numbering shall use the following convention. Each cable shall be allocated

a serial number based on the following:

FC000(X)

Where X in the serial number indicates a number within an incremental numeric

sequence used to identify each cable. The register sequence begins at 1 and increments

each time a new pit is allocated. As an example, the third cable allocated to the register

will have the serial number FC000 (3). Prior to allocating a serial number it is a

requirement to check the fibre cable register to ensure that the number has not already

been used. Having then been allocated a number to create a unique serial number it

must be logged in the register to ensure that its use is not replicated. As part of the

register logging process ensure that all the other detail fields have been completed.

During construction of the network cables they shall be numbered separately based

upon the following;

Where two cables intersect at a splice, each cable will be allocated a separate serial

number.

Where a cable enters and exits a fibre pit and a coil of fibre is provided, the cable

entering and exiting the pit will have the same serial number.

Where a cable enters a fibre pit and passes into an enclosure, the cable that enters and

the cable that exists will be allocated a separate serial number.

B-2 - Fibre Pit Numbering:

Pit numbering shall use the following convention. Each pit shall be allocated a serial

number similar to the following:

FP000(X)

Where X is a number within an incremental numeric sequence used to identify the pits.

The sequence begins at 1 and increases each time a new pit is allocated to the register.

As an example, the third pit allocated to the register will have the serial number

FP00(3). Prior to the allocation of a serial number it is a requirement to check the fibre

pit register to ensure that the number has not already been used. Having then beenallocated a number to create a unique serial number it must be logged in the register to

ensure that its use is not replicated. As part of the pit register logging process ensure

that all the other detail fields have been completed.


48/55




B-3 - Communication Management System Numbering:

Communication Management System numbering shall use the following convention.

Each management system shall be allocated a serial number similar to the following:

BOE-FP0001-EG140001

The serial number is specific; it identifies the type of enclosure as well as a unique

location. The first three letters indicate the functionality of the communications

management system; in this case it identifies the type: breakout enclosure. Next in the

sequence is the location identifier specified by the pit number that the system is located

in (serial number specified above).

The final part of the serial number specifies the type of enclosure itself. In this

particular case it uses the prefix (EG) to identify the Egger ton enclosure. The

remaining numerals used to complete the serial number are created using an incremental

numeric sequence used to identify each system. The sequence begins at 1 and increaseseach time a new management system is allocated to the register.

As an example, the third Egger ton enclosure located in pit 3 will have the serial

number

(BOE-FP0003-EG140003)

Prior to allocating a number it is a requirement to check the Communications

management system register for number allocation to ensure that the number has not

already been used. Having then been allocated a number it must be logged in the

register to ensure that its allocation is not replicated. As part of the register loggingprocess ensure that all the remaining fields associated with the system allocated are

completed.

B-4 - Service Numbering:

A Service Number is provided to each customer so that an initial connection point into

the telecommunications network can be identified. The Service Number may contain up

to three parts, each of which provides a different set of information.

An example of a three part Service Number is shown below.

FC0020-0001-PORTADEL

Most Service Numbers will only contain the first two fields with the last field, an 8 digit

location identifier not being required. The site identifier is only included upon the

request of the customer, where the structure of their service requires it.

The first six digits of the Service Number use the serial number allocated to the cable at

the first point of entry into the network from the main customer premises. This cable

itself will be numbered in the first instance according to Appendix B1. In the case of a

redundant network the standard approach is to choose the lowest of the two fibre cable

numbers that are connected to the switch. This serial number is then allocated to the

Service Number as previously mentioned.


49/55




The second four digits of the Service Number indicate the time slot allocated for the

service on the fibre pair. The telecommunications network has been designed so that

multiple services can share the same fibre path via multiplexing techniques. A service

that has been allocated the first time slot of a fibre pair is allocated the next four digits

of the service number: 0001, as shown above. When other services are allocated to the

remaining timeslots, the numeric numbering sequence reflects their position in the timedomain.

The 8 digit identifier is only added to the Service Number due to the specific design of

the network and in the instance where the customer requests it. It is included to identify

customer premises (physical locations) that the service is routed to. In this instance the

customer has a specific requirement to identify parts of their network. The standard

requires that all services connected to same customer premises use the same 8 digit

identifier. The example Service Number identifies Port Adelaide as a key customer

premises location for the service.
