The FC-LINK QSFP56 200G (4x50G) CWDM4 10km LR4 LC DX Transceiver is a high-performance, hot-pluggable optical module designed for 200GE links over single-mode fiber (SMF) at distances of up to 10km. It combines four 26.5625 GBd PAM4 electrical lanes into four corresponding optical channels, fully compliant with IEEE 200GBASE-LR4 standards. This transceiver delivers superior performance and reliability with an advanced design that incorporates cooled EA-DFB lasers at LAN-WDM 1.3μm wavelengths and four PIN photodetectors with low-power TIAs. The optical signals are multiplexed and demultiplexed onto a single fiber pair through an LC duplex connector, ensuring efficient and reliable data transmission.
