• Amendment 1 for Channels published April 2008

• Amendment 2 for PL and Components approved Feb

2010

• Edition 2.2 consolidated, published Aug 2011 in Europe.

AS/NZS 3080 version Public Comment resolved. Waiting

on publication by SAI Global

• Contains Appendix ZA and ZB for ANZ requirements.

AS/NZS 3080 Ed 2.2 = ISO/IEC 11801 Ed 2.2


• Balanced Permanent Links and CP Link definitions:-

PL1 = Backbone Permanent Link, 2 connectors

PL2 = Horizontal Permanent Link, 2 connectors

PL3 = Horizontal Permanent Link, 3 connectors

CP1 = Horizontal CP Link, 2 connectorsCP1 = Horizontal CP Link, 2 connectors

• PL2 and PL3 limits are already in field testers for

ISO Class EA , F and FA

• OS2 Fibre – Atten. of 0.4dB @1310, 1383, 1550nm

• Has Reduced, Low or ‘Zero’ Water Peak

• Met by Type B1.3 fibre in IEC60793-2-50:2008 @1550

which is same as ITU-T G652d or c

• Also met by Type B6_a fibre IEC60793-2-50 @1625nm • Also met by Type B6_a fibre IEC60793-2-50 @1625nm

which is same as ITU-T G657a also known as

Reduced Bend Radius Fibre or Bend Insensitive Fibre

• If Splicing G657a to G652d, set up for ‘cladding’ alignment

Test in both directions. Expect some Gains.

For ANZ,

• Optical Fibre propagation delay PD = cable sheath length

x 5 ns/m instead of needing to use an OTDR

• Optical Attenuation of connectors containing a splice

e.g. pre-polished stubs, are deemed to be a connector e.g. pre-polished stubs, are deemed to be a connector

and a splice for loss budget calculations

• ORL of two components in close proximity (e.g. MPO

cassette or a stub) shall be ≤ ORL of one connector

12



• ORL measurements may be a field test requirement for

OS1/OS2 APC e.g. NBN fibre

• For ANZ, AS/NZS 3080 Appendix ZA ORL testing for

installation conformance testing is optionalinstallation conformance testing is optional

Optical Fibre Testing

• Encircled Flux – EF is a mode conditioning method to

ensure consistent modal distribution in MMF Launch

cords at the launch into the DUT

• EF defines the launch conditions of a light source.

It will improve Reproducibility when different testers

AS/NZS ISO/IEC 14763.3 :2012


It will improve Reproducibility when different testers

are used to test the same MMF Link

• EF device is required on MMF Launch Cords for

measuring Attenuation with LSPM & OTDR

16

Measurement Uncertainty Depends on testers & test cords

• 1-Test Cord Ref Method has Uncertainty* = 0.1 dB MMF & SMF

• 3-Test Cord Ref Method has Uncertainty* ≤ 0.2 dB MMF

* Current uncertainty values ≤ 0.4 dB SMF

• Apparent Gains shall not exceed measurement uncertainty.

AS/NZS ISO/IEC 14763.3 :2012


• Reasons for Apparent Gains:-

– Non-reference-grade test cords during testing

– Non-reference-grade adaptors during Reference Setting

– Increased light power after insufficient warm-up

– Dirty connectors during Reference Setting

– Disconnected launch test cord after Reference Setting

• Cable pathways are defined as FULL during design when cables

occupy 50% of pathway

• Cable pathway Spare Capacity should be 25 - 30%• Cable pathway Spare Capacity should be 25 - 30%

• Max stacking height of cables in a 100mm bar spacing mesh tray

is 140mm, but … stay 10 mm below tray sides

• Shielded cable Min Bend Radius 60mm for pulling, 40mm for

hand placement

IEEE Directions

100GBE on Fibre

100GBE on 4 lanes of 25G in parallel Optical Fibres

IEEE 802.3bj formed in 2011 – 70 participants

• Full duplex operation only

• IEEE 802.3 Ethernet frame format

• BER at least 10^-12• BER at least 10^-12

• 4-lane 100G over OMx up to y m MMF on 850 nm VCSELs

Could be that x = 4, y = 100

4-lane 40G on OS2 to 40 km SMF - Channel IL <18 dB, WDM 1264.5 – 1337.5 nm

But these are subject to much debate around technology break points (cost, density,

power)

Future 400GBE on SMF ????

39

IEEE Directions

100GBE on Fibre

• 100GBE (4 x 25G) on MMF, length judgements using VCSEL with

spectral width similar to that used for 10GBASE-T are:-

OM3 30 – 40m Target 100m 1.9 dB Ch 1.5 dB

OM4 80 – 120m Target 150m 1.5 dB Ch 1.0 dB

Connecting Hardware

Some say:-

• EoR switching gives lower latency, higher performance, reduced

downtime

• SMF is preferred over MMF in data centres

NO !! To Copper Coated Aluminium Cables

The Standards & ACMA say ....

Copper Coated Aluminium or Steel Cables

Are not defined in ISO/IEC 11801� Fire hazard for any future PoE

� All IDC terminations will corrode
