SFP transceiver module BlueOptics SFP-BXU34-40KM-CP-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-CP-BO is an SFP fiber-optic transceiver module designed for single-mode links up to 40 km. It supports a maximum data transfer rate of 1250 Mbit/s (1000BASE-BX-U) and uses an LC simplex connector with separate transmit and receive wavelengths (transmit 1490 nm, receive 1310 nm). The module is housed in metal for mechanical stability and thermal dissipation, weighs approximately 20 g and offers a long mean time between failures (MTBF) of around 1,000,000 hours. It complies with MSA SFP form-factor standards and includes Digital Diagnostic Monitoring (DDM/DOM) for real-time monitoring of operating parameters where supported by the host hardware.

Advantages

The transceiver provides 1.25 Gbit/s-capable single-mode transmission over distances up to 40 km while maintaining MSA interoperability with common network equipment. Metal housing improves durability and heat dissipation, and DDM support allows remote monitoring of supply voltage, laser bias current, transmit power, receive power and temperature when the host supports it. Low weight and standard SFP packaging make it straightforward to install in compatible switches, routers and other network devices.

Key specifications

How to use

Install the SFP transceiver into a compatible SFP slot on the host device until it latches, then connect an appropriate single-mode LC simplex fiber patch cord. Ensure the fiber polarity matches the transceiver's TX and RX orientation and that the connected device supports 1000BASE-BX-U operation and DDM if diagnostic monitoring is required. Verify link status in the host interface and monitor DDM parameters for signal levels and temperature if available. Remove the transceiver by releasing the latch and pulling it straight out when maintenance or replacement is needed.

Recommendations

Use single-mode fiber with an appropriate link budget and low-loss connectors to achieve the specified 40 km range. Confirm host device compatibility with 1000BASE-BX-U and DDM before deployment, and handle the module and optical connectors with dust caps and ESD precautions to preserve performance and lifetime.
