1. Operation of 1310nm lasers on multimode fiber require the use of a Mode Conditioning Patch Cord to ensure compliance with
IEEE P802.3z Gigabit Ethernet 1000Base-LX. This patch cord will minimize the effects of Differential Mode Delay (DMD) and
ensure the proper Coupled Power Ratio (CPR) for operation of 1310nm lasers over multimode fiber.
2. The optical interface connector dimensionally conforms to the industry standard SC type connector documented in JIS-5973. A
dual keyed SC receptacle serves to align the optical transmission fiber mechanically to the GBIC-1063N, GBIC-1063NS, and
GBIC-1250NS. See Duplex SC Receptacle on page 31 for a drawing of the duplex SC receptacle that is part of the GBIC-1063N,
GBIC-1063NS, and GBIC-1250NS.
