The FC-LINK QSFP-DD 400G (4x100G) 1310nm 2km FR4 LC DX transceiver is a high-performance 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module designed for optical communication applications over distances of up to 2km. The module converts 8 channels of 50Gb/s (PAM4) electrical input into 4 CWDM optical signals, multiplexing them into a single channel for 400Gb/s optical transmission. On the receiver side, it de-multiplexes a 400Gb/s optical input into 4 CWDM optical signals and converts them back into 8 channels of 50Gb/s (PAM4) electrical output.The 4 CWDM channels operate at central wavelengths of 1271nm, 1291nm, 1311nm, and 1331nm, as defined by the CWDM wavelength grid in ITU-T G.694.2. The transceiver features a duplex LC connector for the optical interface and a 76-pin connector for the electrical interface. To ensure minimal optical dispersion over long distances, single-mode fiber (SMF) is required for this module. Host Forward Error Correction (FEC) is also necessary to support transmission over 2km.With its advanced design and adherence to industry standards, this transceiver is an ideal solution for high-speed, long-range optical communication applications.
