Cisco compatible GLC-T Description
EdgeOptic's GLC-T compatible is a Cisco-coded RJ45 copper version of the EdgeOptic 1000M-SFP-T multi-vendor 10/100/1000BASE-T copper SFP transceiver. Cisco reached End-of-Sale on the original GLC-T in June 2017, with GLC-TE designated as its successor. For networks still running GLC-T ports, this compatible module is the in-stock, drop-in alternative that holds the original electrical and mechanical specification.
The module carries Gigabit Ethernet over copper to IEEE 802.3ab (1000BASE-T) and auto-negotiates 10/100/1000 Mbps, so it links at 10BASE-T and 100BASE-TX rates as well. Reach is 100 m over Cat 5, Cat 5e, or Cat 6 unshielded twisted pair through a standard RJ45 connector, with Auto MDI/MDI-X handling straight-through and crossover cabling. It runs from a +3.3 V supply across the commercial 0 to 70 C range and supports digital diagnostics monitoring.
EdgeOptic codes the transceiver EEPROM with Cisco-recognized identification, so the host accepts it as a genuine GLC-T without the service unsupported-transceiver command. The module works across Cisco switches, routers, and firewalls with SFP slots rated for 1000BASE-T. Confirm the slot against the chassis transceiver compatibility table for the running software release.
Copper SFP modules of this class fit wherever Gigabit links run over structured copper rather than fiber. Common uses include LAN aggregation, server-to-switch connections inside a rack, and management or out-of-band links between equipment in the same room. The 100 m reach over Cat 5e or Cat 6 covers most in-building runs, and the RJ45 interface lets an SFP port connect directly to an existing copper plant without media converters. For estates with discontinued GLC-T ports, this compatible keeps those slots supplied without re-specifying the port or changing the cabling design.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor networking platforms, this module is CE and RoHS certified and built to the SFP Multi-Source Agreement. It ships next business day from EU stock with a lifetime warranty. For deployment questions or volume pricing, contact our sales team.
Frequently Asked Questions
Is the Cisco GLC-T still available to buy?
The original Cisco GLC-T reached End-of-Sale in June 2017, so it is no longer orderable as a new part from Cisco; GLC-TE is the Cisco-designated successor. EdgeOptic's GLC-T compatible holds the same 1000BASE-T copper specification and is actively stocked, which makes it a practical way to keep existing GLC-T ports supplied without changing the original part designation.
What is the difference between Cisco GLC-T and GLC-TE?
Both are 1000BASE-T copper SFP modules with a 100 m RJ45 reach; the difference is the operating temperature class. The GLC-T is a commercial-temperature part rated 0 to 70 C, while the GLC-TE is the extended-temperature variant rated -5 to 85 C. Cisco lists GLC-TE as the replacement for the End-of-Sale GLC-T, so deployments that need the wider temperature window should specify GLC-TE.
