SFP transceiver BlueOptics SFP-9GH-BO 1250 Mbit/s RJ-45

The BlueOptics SFP-9GH-BO 1250 Mbit/s RJ-45 is a compact SFP transceiver module designed for 1.25 Gbit/s optical network links. It provides an RJ-45 interface, operates at 3.3 V input voltage and is housed in a durable metal casing. Weighing only 3 g and finished in silver, the module complies with MSA mechanical specifications and is intended for use in switches, routers and other network hardware that accept standard SFP modules.

Advantages

This transceiver supports data rates up to 1250 Mbit/s and offers plug-and-play compatibility with equipment that supports 1000BASE-T SFP modules. Its metal housing provides mechanical protection and stable thermal performance while the lightweight design reduces strain on SFP cages. The module includes support for digital diagnostics (DDM/DOM) to monitor supply voltage, laser bias current, output/input power and temperature in real time where supported by host hardware.

Suitable for

• Upgrading or extending Ethernet links in enterprise and data center networks
• Replacing or expanding SFP ports on switches, routers and storage systems
• Short-range fiber or copper-based connections up to 100 meters when used according to 1000BASE-T guidance
• Applications requiring remote monitoring via DDM/DOM when host supports diagnostics

Key specifications

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

How to use

Ensure the host device supports standard SFP 1000BASE-T transceivers and, if DDM/DOM monitoring is required, that the device exposes diagnostic registers. Insert the BlueOptics SFP-9GH-BO into an empty SFP slot until it seats firmly and latch any retention mechanism provided by the chassis. Connect the RJ-45 cable or appropriate patching as required by your network design. After insertion, verify link status and data rate in the host device management interface and confirm that remote diagnostics (if used) report expected parameters.

Usage recommendations

Use shielded Cat5e/Cat6/Cat6a cables for copper segments to minimize electromagnetic interference. Follow the host vendor’s compatibility list when deploying SFP modules; perform an initial test in a non‑production environment to confirm interoperability and DDM/DOM behavior before large-scale rollouts.
