BlueOptics QSFP-40G-PLR4-LO-BO network transceiver module Fiber optic 40 Mbit/s 1310 nm

The BlueOptics QSFP-40G-PLR4-LO-BO is a QSFP network transceiver module for single-mode fiber links. It supports a maximum data transfer rate of 40 Mbit/s and operates at a wavelength of 1310 nm. The module uses an MPO/MTP connector and is designed to work with hardware that supports QSFP 40GBASE-PLR4 interfaces. With an MTBF of 1,000,000 hours and a compact lightweight design of approximately 40 g, it is intended for installation in switches, routers and storage systems where stable optical connectivity is required.

Advantages

The module follows MSA-compliant QSFP mechanical, electrical and functional specifications to ensure interoperability with compatible platforms. It integrates separate transmitter and receiver channels operating at 1310 nm for bidirectional optical signal transmission over single-mode fiber. Built with high-quality optical and electronic components and tested for compatibility with mainstream hardware, the transceiver offers long service life, DDM/DOM diagnostics support for remote monitoring, and low susceptibility to electromagnetic interference inherent to fiber optic links.

Suitable for

• High-speed uplinks and aggregation links in data centers
• Inter-switch connections and backbone links up to the supported reach
• Fibre Channel over Ethernet and SDH/SONET applications requiring QSFP 40GBASE-PLR4
• Network hardware that accepts QSFP modules with MPO/MTP connectors

Key specifications

• Interface type: QSFP (MPO/MTP connector)
• Maximum data transfer rate: 40 Mbit/s
• Operating wavelength: 1310 nm (transmit and receive)
• Fiber type: single-mode fiber
• Diagnostics: Digital Diagnostic Monitoring (DDM/DOM) compliant with SFF-8472
• Typical weight: 0.04 kg
• Mean time between failures (MTBF): 1,000,000 hours
• Compliance: MSA-compatible; meets common industrial standards (e.g., CE, RoHS)

How to use

Install the QSFP module into a compatible QSFP port on the target device following the vendor instructions for hot-plugging. Connect the module to another transceiver or patch panel using an MPO/MTP single-mode fiber patch cord rated for the desired distance. If the host platform supports DDM/DOM, enable or query the digital diagnostics interface to read real-time parameters such as supply voltage, laser bias current, transmit output power, receive input power and temperature. Verify link status and network configuration on the host device after insertion.

Recommendations

Ensure that the host hardware explicitly supports MSA-compliant QSFP 40GBASE-PLR4 modules and that firmware or software settings allow third-party transceivers, if applicable. Use appropriate single-mode MPO/MTP patch cords and clean fiber connectors before mating. For reliable performance, confirm DDM/DOM compatibility with the system to enable remote monitoring and troubleshooting of optical parameters.
