SFP transceiver module BlueOptics SFP-9431-BO Copper 1250 Mbit/s 1550 nm

The BlueOptics SFP-9431-BO Copper 1250 Mbit/s 1550 nm is a small form-factor pluggable (SFP) transceiver module designed for single-mode fiber and copper-compatible installations that require a compact, hot-swappable interface. The module supports a maximum data transfer rate of 1250 Mbit/s, operates with optical signalling around 1550 nm on the receiver, and is housed in a metal enclosure with a 3.3 V supply requirement. It is intended for integration into network equipment that accepts SFP modules and follows MSA mechanical and electrical standards.

Advantages

The transceiver combines a compact SFP form factor and a metal housing for mechanical durability and effective thermal dissipation. Supporting up to 1.25 Gbit/s throughput, it suits 1000BASE applications and provides stable connectivity over single-mode fiber links. The design follows MSA standards for plug-and-play compatibility with a wide range of networking hardware and includes diagnostics support when the host system implements DDM/DOM functions.

Suitable for

• Upgrading or replacing SFP ports in switches and routers
• Single-mode fiber links in enterprise and carrier networks
• Fiber-to-equipment connections where 1250 Mbit/s throughput is required
• Applications that need compact, hot-swappable transceivers with metal housing

Key specifications

• Maximum data transfer rate: 1250 Mbit/s
• Optical receiver wavelength: 1550 nm
• Housing: metal enclosure for durability and heat dissipation
• Operating supply voltage: 3.3 V
• Product colour: silver
• Connector type: LC simplex for single-mode fiber (MSA-compliant)

How to use

Insert the BlueOptics SFP-9431-BO into an SFP port of a compatible switch, router or other network device while the host is powered down or following hot-swap procedures supported by that hardware. Connect an appropriate single-mode LC patch cable to the transceiver. If the host device supports Digital Diagnostic Monitoring (DDM/DOM), enable or monitor diagnostics via the device management interface to read real-time parameters such as optical power and temperature. Follow the network equipment vendor’s instructions for enabling the corresponding port and configuring link settings.

Usage recommendations

Use single-mode LC simplex patch cords rated for the expected distance and install the transceiver in equipment that documents support for SFP 1000BASE/BX-D type modules. Verify DDM/DOM compatibility if remote diagnostics are required, and avoid excessive mechanical stress on the fiber connector to maintain link quality over time.
