Fiber Infrastructure Revitalization
SUNY Oswego’s case study for the future of your
information infrastructure 6/15/05.
Timothy J KraftRCDD, CCNA,NNDE518.330.1188
The Problem (s)• Campus Construction was going to
break a major fiber connection. – Several major new const. projects are
planned.
• Many single mode fiber segments were completely full.– Technology has moved beyond the ability of
traditional multi-mode fiber.
• Facilities ignores networking costs for construction projects.– We play catch up and work hard to find the
money for some of these projects.
Define Requirements• What are the immediate needs?
– Dorm renovations fiber break.
• Needs on the horizon (12+ months)– New Campus Center– New Dorms– Dept. Reorganizations.
• What are the long term needs– Property the campus owns– Long term building plans
• Physical Redundancy– Major fiber cable is 10ft off of a new building
foundation.– It gets broken we have a major life safety issue.

Physical Layout and Logical redundancy can be very different things!
Decision Point #1• Do we look at just this project or
increase the scope?– We increase the scope so that it fits a
comprehensive plan.– We only do the pieces we need for
today.– We size the project to its final design
• We get facilities involved, to know, to assist, and to team.
Define Assets (Pathways)• Current assets and usage.
– Fiber audit (fiber type, usage, %used)
• Facilities projects (teaming)– GET IN EARLY!!!
• Existing facilities– Duct Bank (existing, abandoned, & ducts available)
– Pole Line (where they go, who owns them, space on Pole)
– Open field (where you can install fiber easily)
– Existing conduit and pathways.• Direct bury fiber build (not in duct bank)
– no additions, CWDM for short term relief.– Direct bury of conduit is a viable option today (Thruway)
Fiber Cable Construction• Single Fiber or Hybrid (Single has only one type of
fiber, Hybrid has more than one.)
• Tight Buffer, like what you see in a building. (1 fiber to 1 jacket)– Strong cable can be used in riser and
plenum spaces.
• Loose Tube outside cable (12 fibers per 1 straw like tube)– Gel filled non-fire retardant
• Cheaper 50’ limit inside of building then transition
– Powder filled limited fire and smoke• More expensive, but you do not have to transition.
(saves money on splicing)
Fiber Termination (loose tube)• Types of connectors available (common)
– ST are no longer supported!– SC for fiber terminations– LC for small form factor equipment
• Types of Terminations– Breakout with direct heat or mechanical
termination.• Labor intensive, cheaper parts
– Pigtail splicing (Fusion or mechanical)• Less labor, higher costs for pigtail.
• Mechanical – Cheaper to do, OK performance, OK length of use.
• Fusion – Slightly more expensive, Great performance, Great life expectancy
Decision Point #2• What type of cable construction do we
use?– Loose Tube for all outside paths
• Ask for both types, dependent upon run.• Contractor provides Powder filled for all runs
– Cheaper if they buy a single roll
– Hybrid Fiber, reduces space needs• Make the major fiber runs uniform in size.
– Cheaper for contractor, cheaper for you.
• Fiber used 62.5/125 multi-mode and 9.2/125 single mode fiber
• Flexible inner-duct MAXCEL to reduce conduit usage. Space is a premium!
Types of Fibers• Multi-Mode (medium distance, speed limitations, more
expensive, cheaper GBIC electronics)
– 62.5/125 Pre 1996 (traditional US Multi-mode fiber)
– 62.5/125 FDDI (traditional US Multi-mode fiber)
– 50/125 (traditionally used in voice applications)
– 50/125 laser Optimized (new data grade product for building applications, VERY limited in outside plant applications)
• Single mode 9.2/125 (Distance, speed, cheap, more expensive GBIC electronics)
Data speeds Vs Distance
Fiber Counts• Installation Labor is the most expensive
cost!• How many do you install?
– Maintain what you have in a building.– Augment what is there.– New Fiber routes to be installed (new buildings or
redundancy)
• Increasing demand on single mode.• 62.5/125 Multi-mode is not dead.• 50/125 is not a outside building
solution for a lot of campuses. (distance)
Cost comparisons• Fiber (Corning Cable Systems 6/2005)
– Single mode 9.2/125 12 fiber/foot $0.30– Multi-mode 62.5/125 12 fiber/foot $1.27– Multi-mode 50/125 12 fiber/foot $1.08– Multi-mode 50/125 LO 12 fiber/foot$2.318
• GBIC VCSEL (Vertical Cavity Surface Emitting Laser) (Cisco state Price 3/2005)
– 1000BASE-SX mm $340.00– 1000BASE-LX sm/mm $676.00– 1000BASE-ZX sm
$2716.00
Cost comparisons (continued)
• Gigabit Equipment (Cisco NY state pricing 3/2005)
– Aggregation Point• 3550-12G 10 GBIC / 2 Copper $6796.00
$679.6/port
– Core Blade (6500)• X6516 16 GBIC ports $13596.00
$849/port
Decision Point #3• Single mode fiber has a longer life span.• We can operate in the VCSEL GBIC cost point.• We can collapse our fiber core switching.
– Reduce complexity– Reduce operational costs– Prepare for another major renovation.
• Maintain the existing 62.5/125 multi-mode plant.– Utilize the multi-mode for other types of services
(security, cameras, fire/life safety & building automation)
• Fiber used 62.5/125 multi-mode and 9.2/125 single mode fiber
Make your Plan• Create a fiber backbone design
– Lay it out on a campus site plan– Lay it out as a schematic
• Define build phases– We can do anything, just not over night!
• Dependencies– Duct Banks, Telecomm. rooms, Money,
Conduits, etc
• Publish your Design– Feed back, Senior management awareness,
Multi-Dept. co-operation.

Decision Point #3• Put in large quantity of single mode
– We are not terminating all of it … just yet.
• Look to collapse the network.– Financial study to be conducted…. Stay tuned– Standards based deployment
• We put in several phases.– Store cable in one place until Facilities can build
duct bank with steam tunnel.
• Re-terminate some exiting fiber– Space, alignment, re-use of plant
• Break up funding associated with building projects. – Pieces are done on different building contracts.
Summary… so far• We want to have a comprehensive deign• We are going to use abandoned Power and
Signal manholes use Maxcell.• We will maintain the existing 62.5/125 mm
system, but augment more toward single mode fiber. Loose tube with SC. We are using Corning glass.
• We have a schedule to meet.• We are teaming with facilities on these
projects• We are going to get the project done while we
have the money.
Request For Purchase• Complete design document!
Ambiguity costs and costs and costs!!!!!!
• Product specific, or Open • Specify terminations, cable construction, glass manufacture, fiber
enclosures, fiber routing, inner-duct type, staging.
• Distance Quotes are “Good Faith” Contractor responsible for cable all footages!
Request For Purchase (Continued-2)
• Define testing procedures and how they are to be conducted with sign offs. – Bi-Directional TDR quote standards– Bi-Directional power meter (Define Wavelengths)– Soft copies of ALL results!
• Bill of Materials– Define products, not quantities!– Campus has final say on any equivalents!
• Termination locations– Where and How (racks,)– Wire Management (Vertical, Horizontal and Slack)
• Labeling– Cables, Patch Panels, Splicing Detail etc
• Scheduling (completed, contingencies)
Request For Purchase (Continued-3)
• Clearly Define Change order Process.– What is acceptable. Who has authority to sign. Billing
• Warranty Manufacture based!– Understand the warranty implications.
• Provide “As Built Drawings”– Define what media and quantities
• Put in Bidder Qualifiers, to provide flexibility in awarding contract.– Winning Deliverables to include Bill of Materials to be used, with
part numbers and quantities. Financials, Similar projects, References, etc.
– Fiber manufacture certifications • Splicing• Installers
RFP Alternatives• Remove old cable.
– Duct banks are full of old abandoned cables– Make room for future projects.– The contractor is there in the manhole
system, during new construction.
• Re-termination– ST connectors are no longer supported– Space consolidation, 72 fibers to 144– Testing re-terminated fibers for Quality
Assurance
RFP Pricing• Budget Pricing for this piece $300K• Average adjusted bid price $265K• Winning Bid $177K
– Lowest bidder usually forgets something.
• Put in Bidder Qualifiers, to provide flexibility in awarding contract.– Winning Deliverables to include Bill of
Materials to be used, with part numbers and quantities.
– Fiber manufacture certifications (Splicing and pulling)
Project Management• Teamed with facilities to have
electrical engineers oversee construction on site.
• Manufacture provide splicing course and what to watch out for.
• Define spot check system, to oversee contractor.
• Check with manufacture on contractors
Thank You!
