QSFP Transceiver Module BlueOptics QSFP-40G-PLR4-EE-BO 40 Mbit/s 1310 nm

The BlueOptics QSFP-40G-PLR4-EE-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s optical links over single-mode fiber at a wavelength of 1310 nm. The module features an MPO/MTP connector and supports simultaneous transmit and receive channels. With a compact form factor and a weight of 40 g, it is intended for use in network switches, routers and other hardware that accept QSFP form-factor pluggable transceivers. The product includes digital diagnostics monitoring (DDM/DOM) for real-time reporting of key operating parameters and is specified with a mean time between failures (MTBF) of 1,000,000 hours.

Advantages

The transceiver follows MSA-compliant QSFP specifications for mechanical and electrical interoperability and uses MPO/MTP connectivity for multi-fiber single-mode links. It provides digital diagnostic monitoring to report supply voltage, laser bias current, transmit power, receive power and temperature, which simplifies remote troubleshooting and maintenance. The module is lightweight and designed for long operational life, supporting stable high-speed optical links with reduced susceptibility to electromagnetic interference.

Suitable for

• 40 Mbit/s Ethernet and Fibre Channel over Ethernet links
• High-speed uplinks between switches and routers
• Long-reach single-mode fiber connections in data centers and telecom environments

How to use

Install the BlueOptics QSFP-40G-PLR4-EE-BO in a compatible QSFP port following the host hardware manufacturer’s guidelines. Use a matching MPO/MTP single-mode patch cord or patch panel to connect the transceiver to the fiber link. Ensure the equipment and cabling are rated for the supported wavelength and single-mode operation. If available, enable and monitor the DDM/DOM interface from the host system to observe supply voltage, laser bias current, optical transmit/receive power and temperature for preventive maintenance and troubleshooting.

Recommendations

Verify that the target device supports QSFP MSA modules and the PLR4 transmission protocol before deployment. Use quality single-mode MPO/MTP cabling and keep connectors clean to maintain optical performance. Monitor DDM/DOM readings periodically and follow the host vendor’s firmware and configuration recommendations to ensure interoperability and stable operation.
