QSFP transceiver module BlueOptics QSFP-40G-PLR4-HU-BO 40 Mbit/s 1310 nm

The BlueOptics QSFP-40G-PLR4-HU-BO is a QSFP fiber optic transceiver module designed for single-mode fiber links with a nominal wavelength of 1310 nm and a maximum aggregated data transfer rate of 40 Mbit/s. The module follows QSFP and MSA mechanical standards, uses an MPO/MTP connector for parallel optical lanes and is specified with an MTBF of 1,000,000 hours. It is compact (approx. 40 g) and intended for integration in networking equipment that accepts QSFP form-factor transceivers.

Advantages

The module provides a standardized QSFP interface and MPO/MTP connectivity, enabling straightforward installation in compatible switches, routers and storage systems. Compliance with MSA electrical and mechanical definitions ensures interoperability across multiple hardware vendors. The transceiver supports digital diagnostics monitoring (DDM/DOM) which supplies real-time operational information such as supply voltage, laser bias current, optical output and input power and temperature for remote troubleshooting. Components are selected to meet industrial quality standards and regulatory requirements.

Suitable for

• 40G aggregated links between switches and data center equipment
• High-speed Ethernet and Fibre Channel over Ethernet (up to 40G)
• Single-mode fiber links over intermediate distances (up to several kilometers depending on link design)
• Replacement or upgrade of QSFP ports in equipment that supports 40GBASE-PLR4

How to use

Install the BlueOptics QSFP-40G-PLR4-HU-BO into a compatible QSFP port following the host device manufacturer's hot-plug and safety procedures. Connect appropriate MPO/MTP single-mode fiber patch cords to the module and ensure correct polarity and lane mapping for 40GBASE-PLR4 operation. Verify that the host platform supports the required 40G mode and, if available, enable or query the digital diagnostics interface to observe real-time parameters. Follow any software or firmware recommendations of the host system to ensure full interoperability.

Recommendations

Use certified single-mode MPO/MTP patch cords and maintain proper fiber cleanliness to ensure signal integrity. Confirm host compatibility with 40GBASE-PLR4 QSFP modules and enable DDM/DOM support on the management platform to monitor module health. For critical links, test a sample module in the specific hardware and software environment to validate performance before mass deployment.
