Uplink Port Transceiver Modules
Table B-3 lists the cabling specifications for the 1GE uplink ports, which are located on SFP transceiver
modules that plug into the front panel.

850-nm wavelength, extended operating temperature range and
DOM support, LC connector
SFP-GE-L 1000BASE-LX/LH SFP transceiver module for MMF and SMF,
1300-nm wavelength, extended operating temperature range and
DOM support, LC connector
SFP-GE-T 1000BASE-T SFP transceiver module for Category 5, 5e, or 6
copper wire, extended operating temperature range and DOM
support (NEBS 3ESD); 10/100/1000-Mbps RJ-45 connector

2. A mode-conditioning patch cord is required when using the GLC-LH-SM module with 62.5-micron diameter MMF for link distances
greater than 984 ft (300 m). In addition, we do not recommend using the GLC-LH-SM module and MMF without a patch cord for very
short link distances (tens of meters) because it may result in an elevated bit error rate (BER).
Install the patch cord between the module and the MMF cable on both the transmit and receive ends of the link. For more information
about the patch cord, see the “Mode-Conditioning Patch Cord Description” section of the document at the following URL:
