SFP transceiver module Cisco GLC-TE=-RFB 1000BASE-T copper Gigabit Ethernet

Cisco GLC-TE=-RFB is a copper SFP transceiver module supporting 1000BASE-T Gigabit Ethernet over twisted-pair copper cabling. It is designed to be inserted into SFP ports of compatible Cisco switches and routers to provide a 1 Gbps link using standard Cat5e or Cat6 cabling. The module enables copper-based uplinks, server connections and edge access where fiber is not required or where existing copper infrastructure is preferred.

Advantages

The module provides a compact SFP form factor that saves space in network equipment while delivering Gigabit Ethernet over copper. It offers broad compatibility with devices that accept Cisco SFP copper modules and allows straightforward use of existing copper cabling without the need for fiber transceivers or media converters. Its plug-in design supports hot-swapping and easy replacement in active network equipment.

Suitable for

• Network uplinks between switches and routers over copper cabling
• Server connections to switches using Cat5e/Cat6 cables
• Edge access ports where copper connectivity is required
• Environments with existing copper infrastructure or where fiber installation is impractical

Key specifications

• Interface: SFP form factor, RJ-45 copper connector
• Data rate: 1000 Mbps (1000BASE-T)
• Media: Twisted-pair copper cabling (Cat5e/Cat6)
• Typical application: Gigabit Ethernet over copper for uplinks and edge connections
• Compatibility: Designed for insertion into compatible Cisco SFP ports

How to use

Insert the Cisco GLC-TE=-RFB SFP module into an available SFP port on a compatible switch or router until it seats firmly. Connect the RJ-45 port on the module to the network device or patch panel using Cat5e or Cat6 cable terminated with an RJ-45 plug. Configure the corresponding switch or router interface as needed for a 1 Gbps Ethernet link and verify link status through device management tools. The transceiver supports hot-swapping; remove the module by releasing any retention mechanism and pulling the module straight out when powered equipment supports hot-removal.

Usage recommendations

Use quality Cat5e or Cat6 cables for reliable Gigabit performance and keep cable runs within recommended length limits for 1000BASE-T. Ensure the SFP slot is compatible with copper SFP modules and consult device documentation for any platform-specific requirements or firmware compatibility notes.
