Fiber optic transceiver module BlueOptics QFX-QSFP-40G-ESR4-BO 40000 Mbit/s 850 nm

The BlueOptics QFX-QSFP-40G-ESR4-BO is a fiber optic transceiver module designed for high-speed 40 Gbit/s data transmission over multimode fiber using an 850 nm wavelength. In a QSFP form factor with an MPO/MTP connection, this transceiver supports simultaneous send and receive functions and is compatible with common hardware platforms that accept 40GBASE-ESR4 QSFP modules. The module is engineered to meet MSA specifications, offers Digital Diagnostics Monitoring (DDM/DOM) for real-time parameter reporting, and is built from quality components to deliver long operational life and reliable optical links.

Advantages

The module provides a compact QSFP interface with MPO/MTP connectivity for aggregated 40 Gbit/s links, reducing space and cabling complexity in data center and enterprise environments. Built to MSA standards and tested for compatibility with major vendor platforms, it incorporates high-quality lasers and ICs to ensure stable optical performance and a long mean time between failures. Integrated digital diagnostics allow remote monitoring of supply voltage, temperature, laser power and current to simplify maintenance and fault analysis.

Key specifications

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch, router or other network device rated for 40GBASE-ESR4 modules. Connect an MPO/MTP multimode patch cable between this transceiver and the corresponding MPO/MTP receptacle on the remote transceiver or patch panel. Ensure the host hardware and firmware support the module and, if required, enable Digital Diagnostics Monitoring in the management interface to read real-time operating parameters. Follow standard ESD precautions when handling the transceiver and keep the optical connectors clean to preserve signal quality.

Recommendations

Use high-quality OM3/OM4 multimode fiber and MPO/MTP patch cables rated for 40 Gbit/s to achieve specified range and performance. Verify compatibility with the target hardware and firmware, and monitor the DDM/DOM readings periodically to detect potential degradation in optical power or temperature trends.
