Description

SFPS delivers fully tested, OEM-compatible optical transceivers, DWDM/CWDM systems, media converters and DAC/AOC cables coded for Cisco, Huawei, Juniper, Arista, HPE, Dell, Nokia and Fortinet platforms, with lifetime warranty and fast global delivery.

SFPS Cisco QDD-400G-FR4-S Compatible QDD-400G-FR4 optical transceiver features a duplex LC connector and supports transmission distances of up to 2 km over parallel single-mode fiber. It converts eight 50 Gb/s PAM4 electrical signals into four CWDM optical channels, multiplexed into a single 400 Gb/s optical link. On the receiving side, the 400 Gb/s optical signal is demultiplexed into four CWDM channels and converted back into eight 50 Gb/s PAM4 electrical outputs. The CWDM wavelengths are 1271, 1291, 1311, and 1331 nm. The 400G QSFP-DD FR4 transceiver is designed specifically for interconnecting data centers, 400G Ethernet. It is typically paired with a 400G QSFP-DD network card and connected to one of the ports of a dual-port 800 Gb/s 2x400G OSFP transceiver, making it ideal for AI Data Center (AIDC) and Data Center Network (DCN) deployments.

SFPS is brand of OEM-compatible optical networking products, including SFP, SFP+, QSFP+, QSFP28 and QSFP-DD transceivers, DWDM/CWDM systems, media converters, and DAC/AOC cables. Every module is 100% pre-shipment tested and coded for seamless compatibility with major platforms such as Cisco, Huawei, Juniper, Arista, HPE, Dell, Nokia and Fortinet backed by a lifetime warranty, fast global delivery, and dedicated technical support for data centers, telecom operators, enterprise networks and system integrators worldwide.
