Glasvezeltransceivermodule BlueOptics X65400A-R6-BO 40000 Mbit/s QSFP 850 nm

The BlueOptics X65400A-R6-BO is a 40 Gbit/s fiber optic transceiver module with a QSFP interface that operates at an 850 nm wavelength. Designed for multimode fiber links and MPO/MTP connectivity, this compact, RoHS-compliant module weighs approximately 20 g and supports short-range high-speed data transfer up to 40,000 Mbit/s. It is built to be compatible with major network hardware platforms that accept 40GBASE-SR4 QSFP transceivers and supports common protocols such as Ethernet and Fibre Channel over Ethernet.

Advantages

The module combines a QSFP form factor with an 850 nm transmitter and receiver to provide reliable 40G short-range connectivity over multimode fiber. Its lightweight silver housing and compliance with MSA and RoHS standards help ensure mechanical and environmental compatibility. Built with tested optical and electronic components, the transceiver offers extended operational lifetime and reduced maintenance needs. Support for digital diagnostics (DDM/DOM) allows remote monitoring of key operating parameters.

How to use

Insert the QSFP transceiver into a compatible QSFP port on your switch, router or storage device until it latches. Connect an MPO/MTP multimode fiber patch cable between the module and the corresponding patch panel or transceiver on the remote device, observing correct polarity and fiber mapping for SR4 channels. Ensure the host device supports 40GBASE-SR4 operation and, if required, enable or verify DDM/DOM monitoring in the host management interface to read real-time diagnostic values.

Recommendations

Use multimode fiber and MPO/MTP patch cords that match the transceiver’s SR4 channel mapping and loss budget, and follow manufacturer-recommended cleaning procedures for fiber connectors before installation. Confirm host compatibility with 40G QSFP modules and enable digital diagnostics only if supported by the system. For optimal performance, keep link distances within multimode SR4 specifications and avoid excessive bends or stress on fiber cables.
