Cisco GLC-T 1000BASE-T SFP Module
Cisco GLC-T 1000BASE-T SFP Module is a compact Gigabit Ethernet copper transceiver designed to provide 1Gbps network connectivity over standard twisted-pair copper cabling. It is suitable for compatible Cisco switches, routers, and other networking equipment requiring a modular RJ-45 Ethernet interface.
Description
The Cisco GLC-T is a 1000BASE-T Gigabit Ethernet SFP transceiver designed to provide copper-based network connectivity through a standard SFP interface. It allows compatible Cisco networking equipment to connect to Gigabit Ethernet networks using existing twisted-pair copper cabling.
With support for 10/100/1000 Mbps Ethernet, the GLC-T provides a flexible solution for network environments where copper connectivity is preferred over fiber. Its compact Small Form-Factor Pluggable (SFP) design makes it easy to deploy, replace, and expand network interfaces without replacing the entire networking device.

1000BASE-T Gigabit Ethernet
The GLC-T is designed for 1000BASE-T Ethernet, providing Gigabit Ethernet connectivity over copper cabling.
This makes it particularly useful for connecting switches, routers, servers, and other network devices where structured copper cabling is already installed.
The module can also support lower Ethernet speeds where supported by the host platform and network configuration, providing additional flexibility for mixed-speed network environments.
RJ-45 Copper Connectivity
Unlike fiber-optic SFP modules, the GLC-T provides an RJ-45 copper interface.
This allows network administrators to use standard Ethernet patch cables rather than installing dedicated fiber infrastructure for every connection.
Typical applications include:
- Switch-to-switch connections
- Switch-to-server connectivity
- Network uplinks
- Router-to-switch connections
- Data center networking
- Enterprise LAN infrastructure
- Existing copper structured-cabling installations
Compact SFP Design
The Small Form-Factor Pluggable design allows the GLC-T to be installed into compatible SFP slots on supported Cisco networking equipment.
Its modular design provides an efficient way to add or change network interfaces while maintaining the flexibility of the host platform.
Data Networking Applications
The GLC-T is suitable for a variety of professional data-networking environments, including:
Enterprise Networks: Connect network infrastructure using existing copper Ethernet cabling.
Data Centers: Provide copper Gigabit Ethernet connectivity for compatible equipment.
Server Connectivity: Connect servers and network appliances to compatible switches.
Network Uplinks: Provide Gigabit Ethernet connections between compatible network devices.
Infrastructure Expansion: Add copper connectivity to equipment with available SFP interfaces.
Key Benefits
Gigabit Performance: Provides up to 1Gbps Ethernet connectivity.
Copper-Based: Uses familiar RJ-45 Ethernet cabling.
Flexible Speeds: Supports 10/100/1000 Mbps operation where supported.
Modular Design: Uses the compact SFP form factor.
Infrastructure Friendly: Allows organizations to utilize existing copper network cabling.
Professional Networking: Suitable for enterprise, data center, and general data-networking deployments.
