NSComm NS-QDD-400G-SR8 400G Base-SR8 QSFP-DD PAM4 850nm 100m MTP/MPO OM3 FEC Optical Transceiver Module
NS-QDD‑400G‑SR8 Transceiver Module | 400 Gbps, 850 nm PAM4, MPO‑16 APC, 100 m
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.
