the 15454-GC-GE-ZX GBIC at each end of the link. For fiber-optic cable spans equal to or greater than 15.5 miles (25 km) and
less than 31 miles (50 km), insert a 5 dB in-line optical attenuator between the fiber-optic cable plant and the receiving port on
the 15454-GC-GE-ZX GBIC at the end of the link.

• Typical loss on a 1310 nm wavelength SMF is 0.5 dB/km.
• Typical loss on a 1550 nm wavelength SMF is 0.3 dB/km.
• The 15454-GC-GE-ZX GBIC requires dispersion-shifted SMF for 100 km (62.1 miles) cable distance.

Multimode Fiber GBIC Port Cabling Specifications
provides cabling specifications for multimode fiber (MMF) GBICs
that you install into Ethernet cards. All GBIC ports have SC-type connectors and the minimum cable distance for all GBICs listed is
6.5 feet (2 m).
6.5 feet (2 m).
Important notes for
:
• The numbers given for MMF refer to the core diameter. For SMF, 8.3 micron refers to the core diameter. The 9-micron and
10-micron values refer to the mode-field diameter (MFD), which is the diameter of the light-carrying portion of the fiber. This
area consists of the fiber core and a small portion of the surrounding cladding. The MFD is a function of the core diameter, the
wavelength of the laser, and the refractive index difference between the core and the cladding.

• When using an LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patchcord (CAB-GELX-625
or equivalent) between the GBIC and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning
