Product Overview

The NSComm NS-QDD‑400G‑SR8 is a high‑density QSFP‑DD optical module engineered for 400 Gigabit Ethernet over multimode fiber. 

It uses eight parallel lanes of PAM4-modulated 50 Gbps signals (8×50G = ~400 Gbps total) on an 850 nm VCSEL array, transmitting over up to 70 m on OM3 or 100 m on OM4 multimode fiber via an MPO‑16 APC connector.

Hot‑swappable and compliant with IEEE 802.3bs (400GBASE‑SR8) and QSFP‑DD MSA, it also supports required host-side FEC and includes Digital Diagnostic Monitoring (DDM/DOM) support across operating conditions.

Compatible Brands

The NS-QDD‑400G‑SR8 is universally compatible across all brands. If you need to verify compatibility with your specific switch model, please click Contact Us Now for assistance.

Product Details

Engineered to Nvidia-compatible NS-QDD‑400G‑SR8 specifications, this transceiver supports 8×50G PAM4 optical channels, running at up to 425 Gbps in dual-rate operation.

It supports breakout to 2×200G or 8×50G links and passed interoperability validation with major platforms. Host-side FEC is required for signal integrity. Power consumption remains under 12 W and the module is certified to operate between 0 °C and 70 °C.
