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

The BlueOptics SFP-1G-RJ45-AR-BO is a copper SFP transceiver module designed for 1000BASE-T Ethernet links. It provides a single RJ-45 port and supports a maximum data transfer rate of 1250 Mbit/s while operating from a 3.3 V input. Housed in a compact metal casing and weighing approximately 3 g, the module is suitable for installation in SFP-compatible switches, routers and network appliances that accept copper SFP modules.

Advantages

This compact, silver-coloured module delivers gigabit-capable copper connectivity with a low-power 3.3 V supply and a metal housing for mechanical durability and EMI shielding. It follows MSA-compliant SFP dimensions and electrical interfaces, enabling compatibility with a wide range of SFP slots. The module supports standard Ethernet protocols up to 1.25 Gbit/s and is engineered for stable operation and long service life when used within vendor-recommended environments.

Suitable for

• Connecting network devices over twisted-pair copper cabling (Cat5e/Cat6) up to typical 100 m ranges
• Upgrading switch or router SFP slots to provide RJ-45 copper ports
• Integrating into server and storage connectivity where copper gigabit links are required
• Replacement of compatible 1000BASE-T SFP modules in supported hardware

How to use

Insert the BlueOptics SFP-1G-RJ45-AR-BO into a compatible SFP slot on a switch, router or network appliance while the device is powered down or following the host manufacturer’s hot-swap procedures. Connect a standard RJ-45 Ethernet cable (Cat5e or higher recommended for gigabit operation) to the module’s RJ-45 port and the remote device. Ensure the host device supports SFP copper transceivers and configure link speed and duplex settings as required by the network environment. Observe ESD precautions when handling the module and avoid forcing the connector into the slot.

Recommendations

For reliable gigabit performance, use quality Cat5e or Cat6 cables and keep runs within standard Ethernet distance limits (around 100 m). Verify firmware and hardware compatibility with the host device vendor; enable any required SFP/MDI settings in the switch or router. Monitor link status after installation and, if available, use the host device diagnostics to confirm stable operation. Store unused modules in anti-static packaging and operate within the environmental limits specified by the host equipment.
