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

The BlueOptics QSFP-40G-PLR4-FR-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s optical links over single-mode fiber. It operates with 1310 nm wavelength for both transmitter and receiver and supports MPO/MTP connectivity according to MSA QSFP specifications. The module is compact and lightweight (0.04 kg) and offers a high MTBF of 1,000,000 hours, making it suitable for deployment in switches, routers, storage systems and other network equipment that accept QSFP 40GBASE-PLR4 form-factor transceivers.

Advantages

The transceiver provides MSA-compliant electrical and mechanical interfaces for broad interoperability and supports Digital Diagnostics Monitoring (DDM/DOM) to report voltage, bias current, transmit and receive power, and temperature in real time. Use of industry-grade laser and IC components supports long operational lifetime and high availability. The MPO/MTP connector enables simultaneous transmit and receive channels over single-mode fiber and the module is manufactured to meet common industrial standards such as CE and RoHS.

Suitable for

• High-speed Ethernet links at 40 Mbit/s over single-mode fiber
• Interconnects between switches, routers and storage arrays supporting QSFP 40GBASE-PLR4
• Data center uplinks and aggregation layers requiring MPO/MTP connectivity
• Environments where remote diagnostic monitoring (DDM/DOM) is required

How to use

Install the BlueOptics QSFP-40G-PLR4-FR-BO into a compatible QSFP port of network equipment that supports the 40GBASE-PLR4 standard. Connect an MPO/MTP single-mode patch cable to the module and route the other end to the corresponding fiber interface or patch panel. Ensure the host device firmware or driver recognizes MSA-compliant transceivers and, if required, enable DDM/DOM support in the host to access diagnostic values. Verify link status and optical power levels after installation and follow the host manufacturer’s power-down and hot-swap guidelines if the device supports hot-pluggable modules.

Recommendations

Use single-mode MPO/MTP fiber patch cords rated for 1310 nm and maintain clean connector endfaces to ensure optimal range and signal quality. Confirm host compatibility with QSFP 40GBASE-PLR4 modules and enable DDM/DOM monitoring when remote diagnostics are needed. Observe ESD precautions during handling and follow manufacturer guidance for hot-swap operations to avoid damage.
