Description
The WST-QD4-SR4-C module is a 400Gb/s QSFP-DD optical transceiver module designed for short-reach multimode
fiber (MMF) transmission. It provides eight electrical lanes operating at 53.125 Gb/s PAM4 signaling and supports a SR4
optical interface for transmission distances up to 100 m over OM4 multimode fiber.
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 850 nm VCSEL laser and the receivers use PIN photodiodes with
TIAs, optimized for short-reach multimode fiber applications.
