Cabling trends in data centres
Switch to Switch links
early market for 100 Gig Ethernet 100m links will cover all needs
Server to Switch links
need 40 Gig from 2016, 100 Gig 2019 majority of server links under 55m

NCS at DCCC: 600 m with 9 MTP connectors
Cisco and others start to guarantee 400m over OM4

Polarity for 10G and 40G/100G
Polarity method for 10G Method defined in standards: method C
Polarity for 40G/100G Not defined in standards, supplier specific 2 types of patch cords because of male/female MPO Nexans use 2 types of interconnection plates
Easy to install, recognise and maintain

Port count during upgrade to 40G
10 G with MTP modules 6 x 10G ports = 60 G capacity Total fibres for 6 ports: 12
40 G with MTP connectors 6 port x 40G ports = 240 G capacity Total fibres for 6 ports: 72
Port count per rack grows over time

Reliability = Cleaning of MTP connectors
Dry cloth cleaner made from antistatic resins
Designed to clean single fibre adaptors: stand alone or in an adaptor

Summary
MPO is the F/O standard for 40G and 100G
The LANmark-OF MPO/LC-Cassettes allow an easy migration from 10G (with LC) up to 40/100G (MPO)
The polarity method used from nexans is designed for easy patchcord handling
The MTP connectivity used from Nexans ensures higher quality
19Only one central port needed for four or eight users.
Benefits of fibre cablingin an office
• Support long distances
• No space restrictions for floor distributors and/or cable trays
• Low refurbishment cost/less disruption
• redundancy at user level
• low loss and right sized POE+ at no additional cost
