NSComm NS-QDD-400G-DR4-S 400G Base-DR4 QSFP-DD PAM4 1310nm 500m MTP/MPO SMF FEC Optical Transceiver Module
NS-QDD‑400G‑DR4‑S Transceiver Module | 400 Gbps, 1310 nm PAM4, MPO‑12 APC, 500 m
Product Overview
The NSComm QDD‑400G‑DR4‑S is a high-performance QSFP‑DD transceiver engineered for 400 Gigabit Ethernet over single‑mode fiber (SMF). It sends four parallel 100 Gbps optical lanes (1310 nm PAM4) via an MPO‑12 APC connector, delivering reliable transmission up to 500 meters.
This hot‑swappable module includes host‑side Forward Error Correction (FEC) and Digital Optical Monitoring (DOM) support for real-time diagnostics. It fully complies with IEEE 802.3bs, QSFP‑DD MSA, CMIS 4.0 and 100G Lambda MSA standards.
Designed for universal compatibility, this module works across major networking brands including Cisco, Juniper, Arista, Dell, Huawei, HPE Aruba, and more.
