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

The BlueOptics QSFP-40G-PLR4-PA-BO is a QSFP fiber-optic transceiver module designed for 40 Mbit/s single-mode optical links at 1310 nm. It implements the 40GBASE-PLR4 transmission profile with an MPO/MTP connector according to MSA standards and is suitable for integration into network equipment that supports QSFP form-factor modules. The transceiver combines transmitter and receiver functionality for simultaneous optical send/receive operation and offers a lightweight design (approx. 40 g) with a high rated reliability (MTBF ~1,000,000 hours).

Advantages

The module follows Multi-Source Agreement (MSA) specifications for electrical, mechanical and functional compatibility, enabling interoperability with a wide range of switches, routers and storage systems. It supports Digital Diagnostics Monitoring (DDM/DOM) for real-time monitoring of voltages, temperature, laser bias and optical power, which facilitates remote troubleshooting and maintenance. Components are selected to meet industrial standards and long lifetime expectations, providing consistent performance for long-distance single-mode links up to the module's supported range.

Suitable for

• 40G optical uplinks between switches and routers
• High-speed server-to-switch interconnects and data center aggregation
• Fibre Channel over Ethernet and SDH/SONET applications up to 40G
• Long-reach single-mode fiber links using MPO/MTP connections

Key specifications

• Interface type: QSFP form factor with MPO/MTP connector
• Maximum data transfer rate: 40 Mbit/s
• Wavelength: 1310 nm (transmitter and receiver)
• Fiber type: single-mode fiber
• Weight: approx. 0.04 kg
• Digital Diagnostics: DDM/DOM (MSA SFF-8472 compliant)
• Standards compliance: MSA QSFP mechanical/electrical profile, CE and RoHS referenced
• MTBF: approximately 1,000,000 hours

How to use

Install the QSFP-40G-PLR4-PA-BO into a compatible QSFP slot on the host device, ensuring the module is properly seated and the device is powered according to the vendor instructions. Connect an MPO/MTP single-mode patch cord to the transceiver port and route the fiber to the corresponding remote transceiver or patch panel. If the host supports DDM/DOM, enable or query the diagnostics interface to monitor operating parameters such as temperature, supply voltage and optical power. Verify link status and negotiation on the host device to confirm 40G operation.

Recommendations

Ensure the host hardware and firmware explicitly support third‑party QSFP modules and the 40GBASE‑PLR4 profile. Use appropriate single‑mode MPO/MTP patch cords and, where possible, clean fiber connectors before mating. Monitor DDM/DOM values during commissioning and periodically in operation to detect signal degradation early. For best results, follow the manufacturer's environment and handling guidelines to maintain long-term reliability.
