SFP transceiver module BlueOptics MP-S31121-3CDL40-BO 1250 Mbit/s 1550 nm

The BlueOptics MP-S31121-3CDL40-BO is an SFP transceiver module for fiber optic networks, supporting a maximum data rate of 1250 Mbit/s and operating at a wavelength of 1550 nm. It uses the compact SFP form factor with an LC duplex interface and is designed for long-distance optical links. The module is lightweight (approx. 40 g) and specified for a high mean time between failures (MTBF) to ensure stable operation in common network hardware.

Advantages

The module follows MSA-compliant SFP specifications and provides simultaneous transmit and receive channels at 1550 nm via LC duplex connectors. Built with quality components, it offers integrated digital diagnostics (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, transmit/receive optical power and temperature. High MTBF and professional component selection aim to deliver extended service life and reduced maintenance needs.

How to use

Insert the SFP transceiver into a compatible SFP slot on a switch, router or other network device while the device is powered according to the vendor’s instructions. Connect LC duplex fiber patch cables with matching wavelength-appropriate singlemode fiber to the TX and RX ports. Ensure the host device supports the module’s 1000BASE-EX class and, if required, enable or verify DDM/DOM support in the management interface to access diagnostic data. Follow ESD precautions during handling and perform link tests after installation to confirm connectivity.

Recommendations

Use singlemode fiber optimized for 1550 nm and high-quality LC patch cables to achieve specified range and optical performance. Verify host compatibility with Maipu-compatible 1000BASE-EX SFP modules when deploying in systems that require vendor interoperability. Monitor DDM/DOM values periodically to detect signal degradation and schedule preventive maintenance as needed.
