SFP transceiver module BlueOptics MP-S31121-3CDL20-BO 1250 Mbit/s

The BlueOptics MP-S31121-3CDL20-BO is an SFP fiber optic transceiver module designed for 1000BASE-LX class applications with a maximum data transfer rate of 1250 Mbit/s. Housed in a compact SFP form factor and finished in silver, the module supports single-mode fiber with LC duplex connectivity and provides bidirectional optical transmit and receive functions at 1310 nm. The module weighs 20 g and is intended for use in networking equipment that accepts standard MSA-compliant SFP transceivers.

Advantages

This SFP transceiver is manufactured to MSA standards for physical compatibility and interoperability with major network platforms that support 1000BASE-LX modules. It supports long-reach single-mode links and implements optical transmission at 1310 nm for simultaneous send/receive over LC duplex fiber. The form factor and interface type make it suitable for direct replacement in switch, router, or storage hardware that accepts SFP modules, while maintaining a compact footprint and low weight.

How to use

Insert the BlueOptics SFP transceiver into a compatible SFP slot on the target network device while the device is powered down or following the device vendor's hot-swap procedure. Connect LC duplex single-mode fiber patch cords to the module's LC connectors, ensuring correct transmit/receive orientation. Configure the host device for the intended protocol (for example, Gigabit Ethernet or Fibre Channel over Ethernet) and verify link status. If supported by the host hardware, enable or query Digital Diagnostic Monitoring (DDM/DOM) to monitor supply voltage, laser bias, output power, received power and temperature in real time.

Recommendations

Use high-quality single-mode LC duplex patch cords and, where possible, test the transceiver in the target hardware to confirm interoperability. Ensure the host device supports 1000BASE-LX SFP modules and DDM/DOM features if remote diagnostics are required. Store and handle the transceiver in a clean, ESD-safe environment and avoid contaminating fiber connectors to maintain optimal performance.
