NSComm NS-QSFP-DD-400G-FR4-S 400G Base-FR4 QSFP-DD PAM4 CWDM4 1310nm 2km Duplex LC SMF FEC Optical Transceiver Module
QSFP‑DD‑400G‑FR4‑S Transceiver Module | 400 Gbps, 1310 nm CWDM PAM4, Duplex LC, 2 km
Product Overview
The NSComm NS-QSFP‑DD‑400G‑FR4‑S is a high-performance QSFP‑DD optical transceiver module designed for 400 Gigabit Ethernet over single-mode fiber. It uses four CWDM optical wavelengths (1271 nm, 1291 nm, 1311 nm, 1331 nm), each carrying 100 Gbps PAM4, aggregating to 425 Gbps optical throughput.
With FEC support on the host side, this module reliably supports up to 2 km reach via a duplex LC connector. Standard compliant with IEEE 802.3cu 400GBASE‑FR4, QSFP‑DD MSA, and 100G Lambda MSA specifications, it includes Digital Diagnostic Monitoring (DDM/DOM) for real-time optical feedback.
Built for universal compatibility, it works seamlessly with devices from Cisco, Juniper, Arista, Dell, Huawei, HPE Aruba, Ciena, Infinera, and more.

Product Details
Designed to meet the NSComm NS-QSFP‑DD‑400G‑FR4‑S specification, the module internally converts eight 50 Gbps electrical lanes into four 100 Gbps CWDM optical channels.
Each lane carries a distinct wavelength and is combined via CWDM multiplexing. Operation requires host-side FEC (Forward Error Correction) for optimal link integrity. Power consumption is typically below 10 W, and the operating range spans 0 °C to 70 °C.
