SFP transceiver module BlueOptics SFP-1G-RJ45-CH-BO Copper 1250 Mbit/s RJ-45

The BlueOptics SFP-1G-RJ45-CH-BO is a copper SFP transceiver module designed for reliable wired network connections at data rates up to 1250 Mbit/s. The module uses an RJ-45 interface and operates with a 3.3 V supply in a compact metal housing with a silver finish and a weight of approximately 3 g. It conforms to SFP form-factor expectations and is intended for use in network equipment that supports 1000BASE-T SFP copper modules.

Advantages

This SFP transceiver provides a standardized RJ-45 copper interface for easy integration into switches, routers and other SFP-capable hardware. The metal housing offers mechanical robustness and electromagnetic shielding while the low weight and compact SFP form factor conserve space in dense installations. The module supports Gigabit Ethernet line rates up to 1.25 Gbit/s, enabling compatibility with common Ethernet, Fibre Channel over Ethernet and SDH/SONET applications within typical copper cable distance limits.

Suitable for

• Gigabit Ethernet uplinks and downlinks in switches and routers
• Server and storage connections that accept SFP copper modules
• Short-run copper links in wiring closets and data center racks (up to standard copper distance limits)
• Network equipment replacement or expansion where RJ-45 SFP compatibility is required

Key specifications

• Interface type: RJ-45 copper connector
• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
• Operating voltage: 3.3 V
• Housing: metal casing with silver colour
• Form factor: SFP (small form-factor pluggable)
• Weight: approximately 0.003 kg

How to use

Install the SFP-1G-RJ45-CH-BO module by inserting it into a compatible SFP port on the network device until it clicks into place. Connect a standard Ethernet cable to the RJ-45 jack on the transceiver and ensure the other end is connected to the remote device or patch panel. Confirm that the host device supports SFP copper modules and that its firmware or software allows operation at the intended link speed. Monitor link indicators on the host device to verify successful negotiation and link establishment.

Recommendations

To ensure reliable operation, use high-quality Cat5e or better twisted-pair cabling for Gigabit links, check device compatibility lists before deployment, and verify that any required digital diagnostic (DDM/DOM) features are supported by the host hardware if real-time monitoring is needed.
