SFP transceiver module BlueOptics SFP-T-CT-BO Copper 1250 Mbit/s RJ-45

The BlueOptics SFP-T-CT-BO Copper 1250 Mbit/s RJ-45 is a compact copper SFP transceiver module designed for Gigabit-class network links. It provides an RJ-45 copper interface with a maximum data transfer rate of 1250 Mbit/s, operates from a 3.3 V input and is housed in a durable silver metal casing. Weighing approximately 3 g, the module is small and lightweight for easy installation in SFP ports that support copper 1000BASE-T functionality.

Advantages

This SFP transceiver offers a standardized RJ-45 interface for straightforward integration into switches, routers and other SFP-capable devices that accept copper modules. Its metal housing provides mechanical durability and electromagnetic shielding, while the low weight and compact SFP form factor simplify handling and mounting. The module supports typical Gigabit Ethernet and related protocols up to 1.25 Gbit/s and is suitable for short-range copper links.

Suitable for

• Connecting switches and routers over copper twisted-pair cabling (up to typical 100 m depending on cable and environment)
• Replacing or expanding SFP copper ports in network equipment that supports SFP-T copper modules
• Environments requiring a compact SFP form factor with RJ-45 connectivity

Key specifications

• Interface type: RJ-45 copper
• Maximum data transfer rate: 1250 Mbit/s
• Operating voltage: 3.3 V
• Housing: metal, silver colour
• Weight: approx. 0.003 kg

How to use

Insert the BlueOptics SFP-T-CT-BO into an available SFP slot on compatible network equipment while the device is powered down or following the vendor's hot-swap instructions. Connect standard Cat5e/Cat6 twisted-pair copper cabling to the RJ-45 port and verify link negotiation and speed in the host device management interface. Ensure the host device supports copper SFP modules and the expected 1000BASE-T/1.25 Gbit/s link mode before deployment.

Recommendations

Use shielded or unshielded twisted-pair cable of appropriate category (Cat5e or higher) and maintain recommended cable lengths and installation practices. Confirm device compatibility and firmware support for third-party SFP copper modules. For monitoring and diagnostics, enable any available digital diagnostic or management features in the host hardware if supported.
