200G QSFP56 FR4 EML CWDM4 2km Transceivers
GIGALIGHT's 200G QSFP56 FR4 optical transceiver modules are designed to support 200G Ethernet, suitable for data center and 5G backhaul links up to 2km over single mode fiber with FEC. The 200G QSFP56 FR4 modules are compatible with IEEE 802.3bs 200GBASE-FR4 and operate at four CWDM wavelengths of 1271nm, 1291nm, 1311nm and 1331nm. With a built-in 200G PAM4 DSP, the module supports four electrical interface lanes which operate in 50G PAM4 encoding mode resulting in 200G (4x50G) data rate.
