Cisco 1000BASE-T SFP Copper Transceiver Module, RJ45

A copper port in a fiber slot is what the Cisco 1000BASE-T SFP Copper Transceiver Module, part number GLC-T, provides. It has an RJ45 connector and runs at 1GbE, with a rated reach of 100 m.

The typical use is connecting a copper-only device to an SFP port. A switch designed with several SFP slots can serve a mix of fiber and copper neighbors with the right modules, and this one covers the copper side. It also lets you reuse installed twisted-pair cabling.

The 100 m rating is the usual limit for gigabit copper, so it suits most runs within a building. The module is an SFP, and it fits SFP cages that accept 1GbE modules. Cisco hosts check the optics they accept, so verify that your switch supports this part number.

A different version of the module exists with an extended temperature rating under another part number, so check which one your environment calls for.

Because copper modules run warmer than fiber modules, packing many into adjacent ports may be limited by the host. Consult the platform documentation before filling a whole line card.

The GLC-T is offered in new, refurbished and used condition. New and refurbished modules carry 1 year or 3 years of warranty, and used modules carry 90 days. Send your quantity and platform for pricing.
