How to use

Insert the BlueOptics ET6401-SR4-BO module into a compatible QSFP port on your switch, router or storage device following the host equipment instructions. Connect an appropriate multimode MPO/MTP patch cable between modules or to a compatible breakout or patch panel. Ensure that the host device supports 40GBASE-SR4 and, if required, enables Digital Diagnostic Monitoring (DDM/DOM) to read supply voltage, laser current, optical output and input power and temperature. Observe proper ESD handling and factory guidelines when installing or removing the transceiver.

Recommendations

For reliable operation, use quality multimode MPO/MTP fiber and follow the distance limits for SR4 multimode links. Verify host compatibility and, if remote diagnostics are needed, confirm DDM/DOM support in the system. Store and handle the module in ESD-safe conditions and avoid bending or contaminating fiber connectors to maintain link performance.
