Cisco GLC-TE 1000 BASE-T Standard Copper SFP Transceiver Module

Cisco GLC-TE SFP transceiver module is a versatile and cost-effective solution for converting compatible switch or router SFP ports into copper-based Gigabit Ethernet links. Supporting 10/100/1000 Mbps operation over standard Cat5e or better copper cabling up to 100 meters, this hot-swappable module enables flexible media choice and seamless integration into existing infrastructure. Designed for enterprise network deployments, the GLC-TE supports auto-negotiation and auto-MDI/MDIX for simplified installation and reliable performance.

Product Features

Hot-swappable SFP form factor

Allows insertion or removal of the module while the system is running, helping minimise downtime and simplify serviceability.

Copper (RJ-45) connectivity

Equipped with an RJ-45 interface, the module connects directly to unshielded twisted-pair (UTP) copper cables, enabling cost-effective Gigabit links using existing wiring.

Multi-speed support (10/100/1000 Mbps)

Auto-negotiates link speed across 10/100/1000 Mbps allowing compatibility with a wide array of network devices and simplifying upgrades.

Support for standard Category cabling

Compatible with Cat5e/6 cables for link distances up to 100 m (328 ft) over copper media.

Broad platform compatibility

Suitable for use in many Cisco switches and routers with appropriate SFP ports — enabling media conversion without changing core equipment.

Product Specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Interface: RJ-45 copper connector, 1000BASE-T (Gigabit over UTP)
• Supported cable: Category 5e or better, length up to ≈100 m (328 ft) over copper UTP.
• Speed: 10 / 100 / 1000 Mbps (auto-negotiation)
• Auto MDI/MDIX: Supported for simplified connectivity.
• Power consumption: Typical low-power design (approx. ≤1 W for copper SFP modules)
• Operating temperature (depending on version): Standard commercial range; some variants support extended/industrial temperatures (-40 °C to +85 °C) for harsh environments.
• Standards compliance: IEEE 802.3, IEEE 802.3ab (1000BASE-T)

Usage & Deployment Tips

• Insert the GLC-TE module into any compatible SFP slot on a Cisco switch or router, and connect a Cat5e/6 UTP cable to a copper Ethernet port at the other end for a Gigabit copper link.
• Ensure the device firmware supports SFP module types: some platforms may require enabling “generic” SFP support if the module is third-party.
• For links longer than ~100 m or in fiber-only environments, consider using optical SFP modules instead of copper.
• When replacing or upgrading modules, check for compatibility with the specific Cisco platform and licensing requirements — Cisco documentation lists supported devices.
• Use quality UTP cabling (Cat5e or better) and maintain good terminations to achieve full Gigabit performance.
