Company Introduction
This 400G DR4 OSFP optical module is an InfiniBand 400Gb/s single-port OSFP transceiver with a DR4
single‑mode parallel design, utilizing a single 4‑channel MPO‑12/APC optical connector. It adopts
100G‑PAM4 modulation technology and supports a transmission distance of up to 500m over OS2
single‑mode fiber. It is designed for InfiniBand NDR end‑to‑end systems. This solution enables seamless integration into compute and storage infrastructures to ensure efficient
high‑performance interconnection. The module is used to connect ConnectX‑7/QSFP112 network
adapters and 2×400G InfiniBand switches equipped with dual‑port optical modules.
