Installing the GBIC Module or SFP Module Interface Cables
Figure 11 SFP Module Showing a Variety of Latches
Note Different manufacturers have different types of latching mechanisms for Gigabit Ethernet SFP modules.
There is no correlation of the type of latch to the model (such as SX or LH) or technology type (such as
Gigabit Ethernet) of SFP modules. See the label for the SFP technology type and model. The SFP
modules use LC-type connectors.
Installing the GBIC Module or SFP Module Interface Cables
This section describes how to attach the interface cables to the GBIC module or SFP module.
Note Optical fiber cables are commercially available; they are not available from Cisco Systems.
Attaching Multimode and Single-Mode Optical Fiber Cables
Attach the appropriate optical fiber cable directly to the SC-type receptacle on the GBIC module or the
LC-type connector on the SFP module. You can use either simplex or duplex connectors for most
devices. (See Figure 12.)
• For simplex connectors, two cables are required, one cable for transmit (TX) and a second cable for
receive (RX).
• For duplex connectors, only one cable that has both TX and RX connectors is required.
Caution If you plan to use a GBIC-LX/LH or GLC-LH-SM at distances greater than 984.25 feet (300 meters)
over 50/125-micron or 62.5/125-micron multimode fiber, to prevent data transmission problems you
must use the mode-conditioning patch cord. (See the “Attaching the Mode-Conditioning Patch Cord”
section on page 22.)
