100G QSFP28 ER1 Transceiver Module (1310nm Single Lambda SMF PAM4 40km LC DDM)

The 100G QSFP28 ER1 optical transceiver modules are designed to support 100G Ethernet, suitable for data center links up to 40km over single-mode fiber. The 100G QSFP28 ER1 module is compliant with the 100G-ER1-40 specification of the 100G Lambda MSA. The transmission end converts 4x25G NRZ electrical signals into 1x100G PAM4 optical signals. The reverse receiving side converts 1x 100G PAM4 optical signal to 4x25G NRZ electrical signal.
