SFP-transceivermodule BlueOptics SFP-1G-RJ45-CN-BO koper 1250 Mbit/s RJ-45

The BlueOptics SFP-1G-RJ45-CN-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 at a supply voltage of 3.3 V. Constructed with a metal housing and weighing approximately 3 g, this compact module is intended for use in SFP-capable switches, routers and other network devices that accept standard MSA-compliant copper SFP modules.

Advantages

The module offers plug-and-play compatibility with devices that support SFP 1000BASE-T interfaces and follows MSA mechanical and electrical guidelines. Its metal casing gives mechanical durability and EMI resilience, and the low weight simplifies handling and installation in high-density chassis. The RJ-45 copper interface enables connection to standard twisted-pair copper cabling for distances up to typical 100 m Ethernet runs at gigabit speeds.

Suitable for

• Gigabit Ethernet uplinks between switches and routers over Cat5e/Cat6 copper cabling
• Network equipment that requires an SFP 1000BASE-T copper transceiver
• Data center patching and server-to-switch connections using RJ-45 ports

Key specifications

• Interface type: RJ-45 copper
• Maximum data transfer rate: 1250 Mbit/s
• Supply voltage: 3.3 V
• Housing material: metal
• Weight: 0.003 kg
• Product colour: silver

How to use

Insert the SFP module into a compatible SFP port on the network device until it latches, then connect a standard RJ-45 twisted-pair cable to the module. Ensure the host device supports 1000BASE-T SFP copper transceivers and that the port is configured for the intended link speed and duplex settings or left to auto-negotiate. After connection, verify link status and correct speed on the host device management interface.

Recommendations

Use Category-rated copper cabling (Cat5e or better) for reliable gigabit links and keep patch cable lengths within standard Ethernet limits (up to 100 m). Confirm host device compatibility with SFP copper transceivers and verify that any digital diagnostic features you expect are supported by the device firmware. Handle the module by its housing, avoid touching electrical contacts, and store unused modules in anti-static packaging.
