How to use

Install the module into a compatible QSFP port according to the host equipment manufacturer’s instructions. Use an MPO/MTP multimode fiber patch or harness rated for 40GBASE-SR4 and ensure proper cable polarity and fiber type (multimode) for reliable transmission. After insertion, verify link negotiation and optical levels on the host device. Follow standard electrostatic discharge (ESD) precautions when handling the transceiver and keep connector endfaces clean to avoid signal degradation.

Recommendations

For optimal performance, use certified multimode MPO/MTP patch cords and verify that fiber distances and modal bandwidth meet 40GBASE-SR4 specifications. Ensure the host device firmware supports third-party QSFP modules if required and perform optical power and link tests after installation. Store unused transceivers in protective dust caps and a dry environment to preserve connector integrity.
