QSFP Transceiver Module BlueOptics QSFP-40G-PLR4-SP-BO 40 Mbit/s

The BlueOptics QSFP-40G-PLR4-SP-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 uses an MPO/MTP connector for parallel optical transmission. The module integrates transmitter and receiver lasers (operating around 1310 nm) and is built to MSA QSFP mechanical and electrical standards to ensure interoperability with supporting network equipment. With an MTBF of 1,000,000 hours and a compact, lightweight design (approximately 40 g), it is intended for use in switches, routers and other networking hardware that accept compatible QSFP modules.

Advantages

The module offers standardized QSFP form-factor compatibility and MPO/MTP connectivity for multi-fiber links, supporting established 40G optical protocols. Compliance with MSA specifications and CE/RoHS industrial standards helps ensure mechanical and electrical interoperability as well as regulatory conformity. Integrated digital diagnostic monitoring (DDM/DOM) provides real-time information on supply voltage, laser bias current, transmit output power, receive input power and module temperature to simplify monitoring and troubleshooting. The compact weight and form factor enable straightforward installation and flexible deployment in dense data center or telecom racks.

Suitable for

• 40G single‑mode optical links between switches and routers
• High-bandwidth interconnects in data centers and campus networks
• Aggregation and uplink connections in storage and server environments
• Environments requiring DDM/DOM-based remote diagnostics

• Weight: approx. 0.04 kg

How to use

Install the BlueOptics QSFP-40G-PLR4-SP-BO into a compatible QSFP port on the network device following the device manufacturer's hot‑swap and handling procedures. Connect an MPO/MTP patch cord to the module and route the other end to the appropriate patch panel or directly to a compatible transceiver. Ensure the host device firmware and hardware support the QSFP module and DDM/DOM functions if diagnostic monitoring is required. Observe standard fiber‑handling precautions: keep connectors clean, avoid bending fibers beyond their minimum bend radius and verify link settings in the network equipment after insertion.

Recommendations

Use certified single‑mode MPO/MTP patch cords and ensure both ends of the optical path use compatible transceivers or patching infrastructure. Verify that the host hardware supports 40GBASE‑PLR4 or equivalent transmission protocol and that DDM/DOM monitoring is enabled when remote diagnostics are needed. Maintain a clean environment for fiber connectors and perform optical power and link tests after installation to confirm expected performance.
