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

The BlueOptics SFP-1G-RJ45-LE-BO is a copper SFP transceiver module designed for 1000BASE-T Ethernet links. It provides an RJ-45 interface and supports a maximum data transfer rate of 1250 Mbit/s while operating from a 3.3 V input. The module is housed in a metal enclosure, is compact and lightweight (approximately 3 g), and is intended for insertion into SFP ports on compatible network equipment that follow MSA standards.

Advantages

The module offers a standardized RJ-45 copper interface compatible with common SFP slots and supports gigabit-class throughput up to 1250 Mbit/s. Its metal housing provides mechanical protection and EMI shielding while keeping the unit lightweight. The device is designed to meet industry MSA specifications for form factor and electrical behaviour, facilitating straightforward integration into switches, routers or other network hardware that accept SFP copper modules.

Suitable for

• Connecting servers, switches, and routers over copper twisted-pair cabling (up to standard copper SFP distances)
• Upgrading SFP ports to support 1000BASE-T RJ-45 connections
• Field replacements and spare inventory for network maintenance

Key specifications

• Interface type: RJ-45 (copper)
• Maximum data transfer rate: 1250 Mbit/s
• Operating voltage: 3.3 V
• Housing: metal enclosure for EMI shielding
• Weight: approx. 0.003 kg
• Colour: silver

How to use

Insert the BlueOptics SFP-1G-RJ45-LE-BO into an SFP slot on network equipment while the host device is powered off or according to the host vendor's hot-swap guidelines. Connect a compatible Cat5e/Cat6/Cat6a RJ-45 twisted-pair cable to the module's RJ-45 port and to the remote device. Verify link status and speed on the host device management interface and ensure the host firmware or software supports third-party copper SFP modules if required. Follow the equipment manufacturer's safety and handling instructions when installing or removing the transceiver.

Recommendations

Use quality shielded or unshielded twisted-pair cabling appropriate for 1000BASE-T, maintain proper cable routing to minimize EMI, and keep firmware and driver levels on network devices up to date to ensure compatibility and reliable operation.
