Description
The WST-QD4-DR4-C module is a 400Gb/s QSFP-DD optical transceiver module designed for datacenter-reach singlemode fiber (SMF) transmission. It provides eight electrical lanes operating at 53.125 Gb/s PAM4 signaling and supports a DR4 optical interface for transmission distances up to 500 m over SMF.
The module integrates optical and electrical components within a QSFP-DD form factor and uses MPO-12/APC connector for optical connectivity. The transmitters are based on 1310 nm EML and the receivers use PIN photodiodes with TIAs, optimized for datacenter-reach SMF applications.
