SFP Transceiver Module BlueOptics SFP-1G-RJ45-NK-BO Copper 1250 Mbit/s RJ-45

The BlueOptics SFP-1G-RJ45-NK-BO is a copper SFP transceiver module designed for 1000BASE-T Ethernet links with an RJ-45 connector. It supports data transfer up to 1250 Mbit/s, operates from a 3.3 V supply and is enclosed in a compact metal housing with a silver finish, weighing approximately 3 g. The module follows MSA form-factor conventions for SFP transceivers and is intended for use in network devices that accept standard 1G RJ-45 SFP modules.

Advantages

The module provides a standardized RJ-45 interface for copper network connections and supports a maximum data rate of 1250 Mbit/s suitable for Gigabit Ethernet and related applications. Its metal casing offers mechanical durability while keeping the unit lightweight for easy installation and handling. The design is compatible with common SFP ports and supports digital diagnostic monitoring when the host device implements the corresponding interface.

Suitable for

• 1 Gbps Ethernet links over copper using RJ-45
• Installation in switches, routers and other network hardware with SFP ports
• Short-run connections up to typical copper Ethernet distances (see host device specifications)
• Environments requiring a compact, hot-pluggable transceiver

Key specifications

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

How to use

Insert the BlueOptics SFP-1G-RJ45-NK-BO module into a compatible SFP slot on the host device while the device is powered off or following the manufacturer’s hot-plugging instructions. Connect a standard RJ-45 copper Ethernet cable to the module’s port to establish a network link. Confirm link status and negotiated speed through the host device management interface and enable digital diagnostic monitoring if supported by the host to access real-time status parameters.

Recommendations

Verify compatibility with the target switch, router or other SFP-capable hardware before deployment and ensure the host device firmware supports third-party SFP modules and DDM/DOM features to take advantage of diagnostic data.
