Optical patch cord paves way for 100G migration

April 9, 2010
The 24-fiber cord with MTP connectivity enables upgrades from 10 to 40 to 100G.

The 100G Migration Patch Cord from Corning Cable Systems is intended to facilitate the conversion from 10- to 100-Gbit/sec thernet in cabling systems designed around a 12-fiber MTP connector interface. "Because 100GBase-SR10 Ethernet multimode fiber electronics utilize a 24-fiber connector, the 100G Migration Patch Cord eliminates the need for recabilng or other major network modification in 100G-ready 12-fiber systems," the company said when announcing the product. "Today, many data center infrastructures are migrating to 12-fiber cabling systems that use array or MTP connectors, which allow for greater density in the backbone and horizontal. MTP or LC modules break out the 12-fiber MTP connectors into duplex LC connectors that are used for duplex fiber serial transmission such as 1G and 10G Ethernet."

The company further explained that its LANscape Pretium EDGE and Plug-and-Play Universal systems migrate from 10 to 40G Ethernet by replacing the MTP-to-LC module with an MTP adapter and a 12-fiber MTP patch cord. Migration from 40 to 100G Ethernet can be achieved on the same 12-fiber system by replacing the 12-fiber MTP patch cord with the new dual 12-fiber-MTP-to-24-fiber-MTP 100G Migration Patch Cord.

The cord "features a flexible round cable, small outer diameter and Corning ClearCurve multimode fiber," Corning Cable Systems says, adding that the cord' ClearCurve fiber allows tight cable routing without negatively impacting system performance.

The 100G Migration Patch Cord is compliant to ANSI/TIA-568-C.3 and meets the polarity requirements of the pending IEEE 802.3ba, 40/100G Ethernet standard.
