Generic cabling systems – Cabling for 40 Gbit/s
ISO/IEC 11801 approved Technical Report
On 14 April 2014 the German DKE/GUK 715.3 "Informationstechnische Verkabelung von Gebäudekomplexen", mirror committee to ISO/IEC JTC 1/SC 25 WG 3 "Customer premises cabling" and to CENELEC/TC 215, "Electrotechnical Aspects of Telecommunication Equipment", mirror committee to ISO/IEC JTC 1/SC 39 "Sustainability for and by Information Technology", published a communication on cabling for 40 Gbit/s:
As part of the future ISO/IEC 11801 series a Technical Report “Guidance for balanced cabling in support of at least 40Gbit/s data transmission” has been approved and will be published shortly.
This Report describes different transmission channels with a maximal length of at least 30 m using four pair symmetrical copper data cables and two connectors.
The Technical Report serves both as a guidline for the IEEE Working Group 802.3bq (40GBASE-T) and as a basis for the planning of 40 GBit/s transmission in data centres (End of Row, Middle of Row, see draft DIN EN 50600-2-4 (VDE 0801-600-2-4):2014).
It is intended to publish the requirements for channel class II contained in the report in a DIN standard.
