Cisco 1000BASE-T SFP - Gigabit Ethernet μονάδα SFP

The Cisco 1000BASE-T SFP - Gigabit Ethernet SFP Module (MPN: GLC-TE-RFB, EAN: 5715063260531) is a compact hot-pluggable transceiver designed to provide 10/100/1000 Mbps Ethernet connectivity over standard copper cabling. The module accepts an RJ-45 connector and supports link distances up to 100 meters on Category 5 or better twisted-pair cable. Engineered for compatibility with Cisco switches and network equipment, this Gigabit Ethernet SFP module is intended for use in data centers, wiring closets, and distributed network subsystems where a reliable copper uplink or copper-to-fiber transition is required.

Advantages

This Cisco Gigabit Ethernet SFP module offers hot-pluggability for flexible maintenance and network upgrades without powering down equipment. The 1000BASE-T SFP form factor enables space-efficient deployment in SFP-equipped switches and routers while supporting auto-negotiation for 10/100/1000 Mbps operation. The module provides standard RJ-45 connectivity up to 100 meters over Category 5 or better, simplifying installation and integration with existing copper infrastructure. Built to Cisco specifications (GLC-TE-RFB), it ensures hardware-level interoperability and predictable behavior in supported platforms.

Suitable for

• Connecting switches and routers to copper-based LANs within 100 m
• Replacing or upgrading SFP copper uplinks in data centers and wiring closets
• Providing flexible hot-swappable Gigabit Ethernet ports in modular equipment
• Mixed copper and fiber deployments where short copper links are required

How to use

Insert the Cisco 1000BASE-T SFP module into an SFP port on a supported Cisco switch or router until it seats firmly. Connect a standard RJ-45 Ethernet cable to the module and to the remote device. Ensure the connected cable meets Category 5 or better specifications and does not exceed 100 meters for reliable Gigabit performance. Verify link and speed status using the host device management interface or port LEDs. For hot-swap procedures, follow the equipment manufacturer's guidelines to avoid unexpected link interruptions in live environments.

Recommendations

Use certified Cisco GLC-TE-RFB modules or vendor-approved equivalents to maintain full compatibility and support on Cisco platforms. Test cable quality and termination when troubleshooting link issues, and avoid exceeding the 100 m maximum copper distance to prevent degradation of Gigabit throughput.
