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

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

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
