SFP copper transceiver CBO SFP-1G-T-BO, 1 Gbit/s, RJ-45

The BlueOptics SFP copper transceiver CBO SFP-1G-T-BO provides 1 Gbit/s data transmission over a standard RJ-45 copper interface. Designed for insertion into SFP ports on switches, routers and media converters, this module enables 1 Gigabit Ethernet links using existing twisted-pair cabling. The compact SFP form factor allows straightforward upgrades and short-distance uplinks without the need to replace fiber components.

Advantages

This SFP copper transceiver supports full 1 Gbit/s throughput while occupying a small SFP slot, preserving switch density. Compatibility with standard RJ-45 twisted-pair cabling reduces installation cost and simplifies network changes. The module is suitable for hot-plug operation and minimizes downtime during upgrades or port changes. Its design is focused on straightforward interoperability with equipment that accepts SFP copper modules.

Suitable for

• 1 Gigabit Ethernet uplinks between switches and routers over copper
• Connecting servers or access points to network switches using RJ-45 cabling
• Media converters or transceiver-equipped devices requiring copper SFP ports
• Short-distance device interconnects within racks or between adjacent rooms
• Network upgrades where fiber replacement is not practical

Key specifications

• Data rate: 1 Gbit/s (Gigabit Ethernet)
• Connector type: RJ-45 (8P8C) for twisted-pair copper cabling
• Form factor: SFP (Small Form-factor Pluggable)
• Cabling: Cat5e/Cat6 or better recommended for Gigabit links
• Typical reach: suitable for short to medium copper runs (horizontal/within-building)
• Operational mode: hot-pluggable transceiver module

How to use

Insert the module into an available SFP port on the target device until it latches. Connect a standard RJ-45 patch cable between the module and the remote device's Ethernet port. Verify link/activity LEDs on both devices and check the switch/router management interface to confirm a 1 Gbit/s negotiated link. For devices that require manual configuration, set the corresponding port speed and duplex to auto-negotiate or to 1 Gbit/s as appropriate.

Usage recommendations

Use high-quality Cat5e or Cat6 copper cabling and maintain proper cable management to ensure stable Gigabit performance. Avoid exceeding recommended cable lengths for copper Ethernet runs and ensure the SFP port firmware or drivers on your equipment support third-party copper SFP modules to prevent compatibility issues.
