Modulo SFP Cisco GLC-T 1000BASE-T 1000Mbps 1G rame RJ-45

Cisco GLC-T 1000BASE-T SFP module provides Gigabit Ethernet connectivity over copper using a standard RJ-45 interface. Designed to plug into SFP ports on compatible Cisco switches and routers, this 1G copper transceiver supports 1000 Mbps data rates over Cat5e or Cat6 cabling. The module offers hot-pluggable installation and compatibility with standard SFP form-factor ports for straightforward integration into server uplinks, switch interconnects and network upgrade projects where copper Gigabit links are required.

Advantages

The Cisco GLC-T module delivers reliable 1G copper connectivity with a standard RJ-45 connector, enabling use of existing structured cabling (Cat5e/Cat6) without the need for fiber optics. Its SFP form factor supports hot swap installation and compact port density on network equipment. The module is compatible with Cisco branded platforms that accept SFP transceivers and adheres to 1000BASE-T signaling for predictable performance in enterprise LAN environments.

Suitable for

• Server uplinks to switches requiring 1 Gbps copper links
• Switch-to-switch interconnects within wiring closets and data centers
• Network upgrades where existing Cat5e/Cat6 cabling is retained
• Environments needing hot-pluggable SFP copper transceivers for flexible port management

Key specifications

• Brand: Cisco
• Model / MPN: GLC-T=-RFB
• Standard: 1000BASE-T (Gigabit Ethernet over copper)
• Interface: RJ-45 (copper)
• Speed: 1000 Mbps (1 Gbps)

How to use

Insert the Cisco GLC-T module into an available SFP port on a compatible Cisco switch or router until it clicks into place. Connect a standard Cat5e or Cat6 Ethernet cable to the module's RJ-45 connector and to the remote device. The device should detect the module automatically and negotiate 1000 Mbps link speed if the connected port and cable support Gigabit Ethernet. To remove the module, follow the host equipment's hot-swap instructions and gently pull the module from the SFP slot.

Recommendations

Use the GLC-T module with verified Cisco platforms that support SFP copper transceivers and ensure firmware or software compatibility if required. For reliable 1 Gbps performance, use Cat5e or Cat6 cabling of appropriate length and quality and avoid excessive bends or damage to the cable. Observe electrostatic discharge (ESD) precautions when handling the module and follow the host equipment manual for insertion and removal procedures.
