Corning Cable Systems' LANscape Pretium® 550 Cable Solutions Meet the New OM4 Multimode Fiber Industry Standard


HICKORY, N.C. - Corning Cable Systems LLC, part of Corning Incorporated's (NYSE:GLW) Telecommunications segment, announces that its Pretium® 550 cable solutions are OM4 compliant, meeting the new OM4 standard for laser-optimized, high-bandwidth, 50 micron fibers approved by the Telecommunications Industry Association (TIA) in August 2009.

Bandwidth requirements for the new OM4 standard are identical to OM3 with the exception of the 850 nm values. At 850 nm, both the laser-based effective modal bandwidth (EMB) and the legacy overfilled launch (OFL) bandwidth are increased from the OM3 requirements. The increased EMB bandwidth supplements system margin and extends distance for 10G in addition to 40G and 100G, as evidenced by the IEEE's recent approval of a task force to develop guidance for 40G and 100G Ethernet data rates. There are no industry applications that specify or utilize the increased OFL bandwidth.

                                         OM3(MHz∙km)	        OM4(MHz∙km)
Effective Modal Bandwidth (850nm) 2000 4700
Overfilled Bandwidth (850nm) 1500 3500
Overfilled Bandwidth (1300nm) 500 500

Video applications, virtualization and convergence are driving the need for higher data rates and the subsequent new standard. Corning Cable Systems Pretium 550 OM4-compliant cabling solutions provide a pathway to future-proof networks and ensure that bandwidth requirements are met or exceeded.
