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

The BlueOptics QSFP-40G-PLR4-GM-BO is a QSFP fiber optic transceiver module designed for high-speed optical links. It supports a maximum data rate of 40 Mbit/s and operates at a wavelength of 1310 nm over single-mode fiber. The module uses an MPO/MTP connector and implements the 40GBASE-PLR4 physical layer format according to MSA QSFP standards. With a compact, lightweight design (approximately 40 g) and an MTBF of around 1,000,000 hours, the transceiver is intended for deployment in switches, routers, storage systems and other network equipment that accept QSFP 40GBASE-PLR4 modules.

Advantages

The module provides standardized QSFP electrical and mechanical compatibility and supports simultaneous transmit and receive operation over multi-fiber MPO/MTP connections. Built to MSA specifications, it includes digital diagnostics (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature where the host device supports these reports. The combination of single-mode 1310 nm optics and PLR4 signalling enables links at up to 40G over extended distances with immunity to electromagnetic interference. The transceiver is lightweight and designed for easy hot-pluggable installation.

Suitable for

• 40G Ethernet aggregation and spine links
• Fibre Channel over Ethernet (FCoE) and high-speed storage interconnects
• Carrier and data center backbone connections over single-mode fiber

How to use

Insert the QSFP transceiver into a compatible QSFP port on the host device following the equipment manufacturer's hot-plug procedures. Connect the MPO/MTP fiber patch cord to the transceiver ensuring correct polarity and clean connector endfaces to maintain signal quality. Verify link negotiation and module diagnostics via the host management interface; enable DDM/DOM monitoring if the host supports it. For reliable operation, use single-mode fiber infrastructure rated for the target link distance and observe proper cable routing to avoid excessive bending or stress on the fiber.

Recommendations

To ensure optimal performance, clean MPO/MTP connectors before mating, verify compatibility with the host device's supported transceiver list, and confirm that the host supports PLR4 signalling and DDM/DOM if diagnostics are required. Use appropriate single-mode patch cords and patch panels, and perform link validation tests after installation.
