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

The BlueOptics QSFP-40G-PLR4-QL-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s optical data transfer over single-mode fiber. It operates at a nominal wavelength of 1310 nm, features an MPO/MTP connector compatible with MSA QSFP interfaces, and is supplied as a compact module weighing approximately 40 g. The module includes both a transmitter and receiver optimized for 40GBASE-PLR4 applications and provides digital diagnostics monitoring (DDM/DOM) support where the host hardware implements that interface.

Advantages

This QSFP transceiver offers a compact QSFP form factor with MPO/MTP connectivity suitable for high-density installations and follows MSA specifications for electrical and mechanical interoperability. The module supports DDM/DOM for real-time monitoring of operating parameters, and its design targets long operational life with a manufacturer-stated MTBF of 1,000,000 hours. Compatibility testing is performed to ensure functional interoperability with hardware platforms that support the original 40GBASE-PLR4 QSFP modules.

Suitable for

• 40GBASE optical links over single-mode fiber
• High-density switch and router QSFP ports
• Data center uplinks and interconnects
• Applications requiring MPO/MTP connectivity and DDM monitoring

Key specifications

• Interface type: QSFP (MSA compliant)
• Maximum data transfer rate: 40 Mbit/s
• Optical wavelength: 1310 nm
• Connector type: MPO/MTP
• Fiber type: Single-mode fiber
• Weight: 0.04 kg
• Digital Diagnostics Monitoring: supported (requires host support)
• Mean Time Between Failures (MTBF): 1,000,000 hours

How to use

Install the transceiver into a compatible QSFP slot on a switch, router or other network device that supports 40GBASE-PLR4 modules and MSA-compliant QSFP form factors. Connect an MPO/MTP single-mode fiber patch cord to the module taking care to match polarity and fiber orientation. If the host device supports DDM/DOM, enable or read diagnostics through the device management interface to monitor supply voltage, laser bias current, optical transmit/receive power and temperature. Follow the host vendor’s instructions for hot-plugging and safe removal.

Recommendations

Use factory-grade single-mode MPO/MTP patch cords and, where possible, route fibers via a patch panel to maintain optimal insertion loss and reach. Verify that your hardware platform explicitly supports 40GBASE-PLR4 QSFP modules and that firmware allows third-party transceivers if required. For reliable long-term operation, ensure adequate cooling in the equipment bay and periodically monitor DDM values when available.
