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

The BlueOptics QSFP-40G-PLR4-CN-BO is a QSFP fiber optic transceiver module designed for high-speed single-mode optical links. It supports a maximum data transfer rate of 40 Mbit/s and operates at a nominal wavelength of 1310 nm. The module is lightweight (approximately 40 g) and complies with QSFP MSA form-factor standards, provides MPO/MTP connectivity and includes Digital Diagnostics Monitoring (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, output power, received power and temperature. The transceiver is specified with a long mean time between failures (MTBF) for reliable continuous operation in network equipment that supports compatible QSFP-40G-PLR4 modules.

Advantages

The transceiver combines single-mode optical transmission at 1310 nm with QSFP electrical and mechanical compatibility, enabling 40G optical links over MPO/MTP connections. Built to MSA guidelines, it supports DDM for simplified remote diagnostics and maintenance. Its lightweight design and standardized QSFP interface make it straightforward to install in compatible switches, routers and other network devices. The module is manufactured using industry-grade components and tested for interoperability to provide stable long-term operation.

How to use

Handle the transceiver by its housing and avoid touching the optical interfaces. Insert the QSFP module into a compatible QSFP slot until it latches, and secure the MPO/MTP fiber connector to the module's receptacle. Ensure the host device supports QSFP-40G-PLR4 compatible modules and, if required, enable DDM/DOM in the management interface to read diagnostic values. Use appropriate single-mode patch cords and verify polarity and fiber routing on patch panels. Follow standard ESD precautions during installation and remove dust caps from connectors immediately prior to mating.

Recommendations

For optimal performance, use high-quality single-mode MPO/MTP patch cords and ensure both ends of the optical link use compatible QSFP-40G-PLR4 transceivers or transceiver types recommended by the hardware vendor. Verify that the host firmware supports third-party QSFP modules and enable digital diagnostics monitoring where available for proactive link maintenance. Maintain clean connectors and perform acceptance testing after installation to confirm link budget and signal levels.
