QSFP Transceiver Module BlueOptics QSFP-40G-PSM4-LR-BO 40 Mbit/s 1310 nm

The BlueOptics QSFP-40G-PSM4-LR-BO is a QSFP fiber-optic transceiver module designed for 40 Mbit/s optical links over single-mode fiber. It uses a 1310 nm wavelength for transmit and receive paths and is housed in a metal enclosure for mechanical robustness. The module supports MPO/MTP connectivity according to MSA standards, features Digital Diagnostics Monitoring (DDM/DOM) for real-time diagnostic data, and is intended for use in network equipment that accepts QSFP pluggable modules.

Advantages

This transceiver provides a compact QSFP form factor with MPO/MTP interface for simultaneous transmit and receive over multiple fibers, facilitating dense 40 Mbit/s links. Metal housing improves durability and thermal performance, while the module's design follows MSA specifications for interoperability with compatible network switches, routers and storage systems. Built-in digital diagnostics enable remote monitoring of supply voltage, temperature, laser bias current and optical power levels to aid maintenance and troubleshooting.

Suitable for

• High-bandwidth uplinks between switches and routers
• Data center interconnects over single-mode fiber
• Storage area network and server aggregation links
• Fibre Channel over Ethernet and SDH/SONET applications up to 40G

How to use

Install the QSFP transceiver into a compatible QSFP port on your switch, router or other network device while the host system is powered down or following the host vendor’s hot-plug procedures. Connect an MPO/MTP single-mode fiber patch cord between transceivers or to a corresponding patch panel. Ensure the host hardware supports QSFP modules and, if you need DDM data, confirm that the system firmware or management interface exposes digital diagnostic information. Follow standard ESD precautions when handling the module and keep fiber connectors clean to maintain link quality.

Recommendations

For reliable performance, use certified single-mode MPO/MTP patch cords and proper patch panels, verify transceiver compatibility with the target hardware, and validate link parameters with diagnostic feedback. Clean connectors before mating and monitor DDM values to detect optical power or temperature deviations early.
