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

The BlueOptics QSFP-40G-PLR4-UQ-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s optical data transfer over single‑mode fiber. Operating at a wavelength of 1310 nm, this compact module (weight 40 g) follows MSA QSFP standards and provides a high mean time between failures (MTBF) of 1,000,000 hours for sustained availability. It includes MPO/MTP connectivity and supports common high‑speed protocols such as Ethernet and Fibre Channel over Ethernet within the specified optical reach.

Advantages

The module is manufactured to MSA-compliant QSFP specifications to ensure electrical, mechanical and functional interoperability with compatible network hardware. It supports simultaneous transmit and receive operation via optical lasers at 1310 nm and provides Digital Diagnostics Monitoring (DDM/DOM) for real‑time readouts of supply voltage, laser bias current, transmit output power, received input power and temperature when the host hardware supports these features. Component selection and production testing are performed to deliver consistent functionality and long operational life.

Suitable for

• High‑speed uplinks between switches and routers
• Data center interconnects and server farm aggregation
• Enterprise SAN links using Fibre Channel over Ethernet
• Optical backbone links requiring MPO/MTP connections

Key specifications

• Interface type: QSFP form factor with MPO/MTP connector
• Wavelength: 1310 nm (transmit and receive)
• Maximum data transfer rate: 40 Mbit/s
• Fiber type: Single‑mode fiber
• Typical weight: 0.04 kg
• Digital Diagnostics: DDM/DOM support (if host supports feature)
• Compliance: MSA QSFP mechanical and electrical specifications
• Reliability: MTBF approximately 1,000,000 hours

How to use

Install the QSFP transceiver into a compatible QSFP slot on the host device following the manufacturer's insertion and removal procedures. Connect the module to another MPO/MTP equipped transceiver or patch panel using appropriate single‑mode fiber patch cords rated for 1310 nm operation. Verify link status in the host device software and enable Digital Diagnostics Monitoring if supported to access operational parameters. Ensure that the host hardware officially supports QSFP modules of this class to avoid compatibility issues.

Recommendations

Use quality single‑mode MPO/MTP patch cords and maintain proper fiber cleanliness to preserve optical performance. Confirm that the target hardware supports 40G QSFP modules and DDM/DOM if remote diagnostics are required. For troubleshooting, compare DDM readings against expected values for supply voltage, laser bias and received power, and keep firmware of network devices up to date to maximize interoperability.
