Nvidia MMA1Z00-NS400-T 400GBASE‑SR4 QSFP112 Module
Overview :
The Nvidia MMA1Z00‑NS400‑T is a pluggable QSFP112 optical transceiver designed for short‑reach multimode fiber links at 400 Gb/s. Network and data center engineers deploy it on QSFP112 ports of adapters or DPUs to connect to switches or breakout modules in Ethernet fabrics. It uses 4×100G‑PAM4 signaling over an MPO‑12/APC interface with an 850 nm VCSEL laser for multimode fiber. The module supports up to 50 m on OM4 or 30 m on OM3 fiber and operates within a standard commercial temperature range.
