1. High Sd ethnt

The IEEE 802.3ba group has moved the project orward without delays

and the new standard is still expected to be published to plan in June

2010. The objectives include the provision o 8 new physical layers:

40G

- 10km on SMF (a duplex link)

- 100m on OM3

(an 8 way multi-lane link using MPO connectivity)

- 7m on a copper assembly

(a twinax CX4 technology solution)

- 1m on a backplane

100G



- 100m on OM3

(a 20 way multi-lane link using MPO connectivity)

- 7m on a copper assembly (a twinax CX4 technology solution)

The original reach target or copper assemblies was 10m but due to

technical issues this has been reduced to 7m. Signicantly, in the May

meeting it was agreed that OM4 would also be recognised as a cabling

solution, it oers the advantages o either extending the reach up to

125m or providing a higher optical loss budget on shorter links or the

40G and 100G multi-mode bre solutions.

2. p v ethnt

The nal drat o the new PoE-plus standard IEEE 802.3at is now in

circulation with publication expected in September 2009.

It denes a higher power delivery than 802.3a with 25.5W supplied

on two pairs and almost double that level on our pairs. The cabling

committee ISO/IEC JTC1 SC25 WG3 has drated a document (ISO/IEC

29125 currently at pDTR status) which describes the heating eects on

cabling caused by dierent current loads and provides guidance on

mating and un-mating connectors whilst under load.

CablinG standardisation

The ISO/IEC JTC1 SC25 WG3 and CENELEC TC215 committees work

closely together in the standardisation o generic cabling. A summary

o their current activities is shown in the tables (overlea).

EuropEan dirECtivEs

On the On May 18th 2009 the EC passed Mandate 443 to CEN/CENELEC

to prepare standards or the CPD. Accordingly CENELEC have drated

a plan o action to submit back to the EC or approval.

The CENELEC cable committees are in dierent states o readiness on

the standards. Whilst the necessary cable test standards are in drat

pending approval, and the communications cables committees have

product standards which require simple revision to reerence the new

test standards, the power cable committees position is less clear.

Mandate 443 covers three dierent saety aspects and describes

the methods o attestation to conormity required. The parts are:

resistance to ire; reaction to ire & dangerous substances.

The c lassi icat ion o the react ion o cables to i re has been the

most contentious area o debate on this topic.

It is estimated that transition to the Directive requirements will take

two years rom now, adoption o the legislation will be a decision o

individual member states.

Brand-Rex closely ollow developments in standardisation and

legislation across the spectrum o bodies directly involved in, and

associated with, structured cabling markets. This report does not

cover all areas o activity in this eld and should not be used as a

singular reerence.

It will dene Class EA & FA permanent links and components, it will

also include OM4 and lower bend loss SMF and it will acknowledge

the new 40G and 100G applications

It will advise what temperature rise can be expected rom dierent

types o cabling is under load

Will recommend that a minimum o ClassEA and OM3 perormance
