200G QSFP56 ER4 EML LWDM4 40km Transceivers

GIGALIGHT's 200G QSFP56 ER4 optical transceiver modules are designed to support 200G Ethernet, suitable for data center and 5G backhaul links up to 40km over single mode fiber with FEC. The 200G QSFP56 ER4 modules are compatible with IEEE 802.3cn 200GBASE-ER4 and operate at four LWDM (short for LAN-WDM) wavelengths of 1295.56nm, 1300.05nm, 1304.58nm and 1309.14nm. 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.Get a Quote
