Polarity

Pins

- maintain transmission path from Tx to Rx. Standard covers Method A, B and C.

– mates male (pinned) connector to female (non-pinned) connector.

– consider both current and future insertion Loss (IL) and reach requirements

Keyway-up Male (Pins)

• Maintaining polarity with LC

connectors was simple

• Pins (Gender)

• Precisely align the mating connectors

• Creates male/female pair

• Polarity - ANSI/TIA-568-C.0

• Keyed/Maintains orientation

• Method A, B and C

• Complies to MPO connector standards

- IEC-61754-7 and EIA/TIA-604-5 (FOCIS 5).

3 Patching -Interconnect

Male to female

• Female MPO gender is recommended for 40/100G patch field(s)• Avoid a mixed polarity environment

• Method A and Method B (multimode) mixed in the same DC’s has been known

• >6 permutations• trunks x interconnect x fibre grade x IL performance x length

Testing 40G

MPO Channels

Remove uncertainty

Increase ‘time to revenue’

Be on budget and on time

22

Testing - Basics

• IEC 61282-15 (draft only) pending publication - Testing multi-fiber optic cable plant terminated with MPO connectors

• Purpose built 40G testers from leading brands - Unidirectional testing (first window - 850nm)

- Polarity/miss-wire checking

- Fixed gender test heads – testing all 12 fibers at once

• Cleaning challenges - Inspect, clean, inspect process (ICI) - best practice

- Debris migrates towards pins and is a challenge to clean effectively- PanMPO eliminates the need for multiple styles of MPO cleaner

23

Fast FACT

PanMPO *uniquely facilitates fast & effective field

testing of both male and female links (trunks) in

accordance with the ‘one jumper’ reference method

*no need to change manufacturers test equipment

• The ‘single Jumper reference’ is recommended in international standards for testing cabling links.- this method provides the highest level of test certainty.

A move toward 16 fibre units for Multimode

• Moving from 10G per lane to 25G per lane• Fibre >10G

• Likely upgrade paths (mm) results in units of 4 fibers:• 40G 10G per fibre = 8 (2x4F) fibers

• 100G 25G per fibre = 8 (2x8F) fibers

• 400G 25G per fibre = 32 (2x16F) fibers

• Discussions in IEEE/TIA to support: • 16-pin MPO connector (TR 42.13)

• Polarity descriptions that cover n-number of fibre units (TR 42.11)

• 4 new fibre colors to support 16-fiber ribbons bundles (TR 42.12)

WideBand MMF - Highlights

• 4x the bandwidth of OM4 fibre

• Supports legacy 850nm OM4 applications

• Support for duplex 100Gb/s technology Finistar, Juniper, Huawei, Dell, Lumentum

• Will support 8 fibre 400Gb/s technology

• Panduit is LEADING the standards group for WBMMF • Brett Lane (Panduit) is chairman of TIA Joint Task Group to develop the next generation

multimode fiber (Wide Band Multimode Fiber) TIA TR-42.11 and TR-42.12 to develop specification for Wide-Band Multimode Fibre

• Participation from diverse group, including active device and systems vendors

• Goal for TIA specification be mirrored by IEC 86A

32

RE-CAP

• MPO cabling has increased relevance & lifecycle (>ROI)- Enable a 1:1 migration path to 40G, 100G and now, scope for 400G

With existing horizontal cabling + follow best practice.

• Raise performance certainty with PanMPO- Unique test methodology guarantees highest ‘certainty’

• On-time on-Budget - MAC’s are simple/more reliable making both primary install and future upgrades faster

• Connector cleaning and test efficiencies

• Reduce capital expenseLower inventory & re-use existing infrastructure when migrating with PanMPO

33

Take Away

• Leader for Fibre/Copper Transmission

• Leader for Fibre/Copper Distribution

• Strengthening MM/PanMPO market• Unique value proposition with PanMPO & HDFlex

• ½ the risk of downtime

• 50% easier to scale/migrate

• Faster to deploy

• Lower cap-ex, improved ROI

Why 25G Ethernet?

• 25G CFI July 2014• Twinax and Optical

• Focus today is on cloud

• Next gen equipment is optimized for 25G signaling

• Considered a logical migration path to 100G
