Cisco SFP (mini-GBIC) Transceiver Module | GLC-TE=

The Cisco GLC-TE= is a 1 Gbps SFP (mini-GBIC) transceiver with an RJ-45 10/100/1000Base-T port, suited to network teams connecting compatible networking equipment over twisted-pair Ethernet.

Recommended For

• Network administrators adding an RJ-45 copper link to a Cisco device with a compatible SFP slot, such as when the available connection is Ethernet over twisted-pair cable rather than fiber.
• IT teams reusing existing copper Ethernet cabling for a Gigabit link of up to 100 meters, where replacing the cable run with fiber is not needed.
• Operators of installations with wider-than-standard temperature conditions who need a copper SFP: Cisco identifies the GLC-TE as an extended-temperature module.
• Network engineers connecting an SFP-equipped device to an existing copper Ethernet handoff, provided the exact host, port, and required link speed support the GLC-TE.

Real-World Use Scenarios

• When a compatible switch has an available SFP slot but the nearby device uses Ethernet, install the GLC-TE and connect it with twisted-pair cable; the SFP slot can then provide a copper RJ-45 network connection.
• To make a copper uplink between switches, connect compatible SFP slots with an Ethernet cable and GLC-TE modules; the link can carry network traffic without using fiber, provided both ports support the modules and are configured for the connection.
• When extending an existing copper network to a switch that has an unused, compatible SFP slot, use the GLC-TE to connect the installed twisted-pair cabling; on a supported link within the cable’s rated distance, it provides a standard Ethernet connection rather than a fiber conversion.
• For a short in-building connection to a firewall or other Ethernet-equipped network device, plug its RJ-45 cable into the GLC-TE in a compatible switch; the switch can use that copper link for the device’s network connection, with VLAN and port settings configured as needed.
• In an equipment cabinet where temperatures may exceed the standard range for a conventional transceiver, the GLC-TE’s extended-temperature rating may suit the environment; confirm the switch supports the module and that the cabinet stays within its specified operating range.
