100G QSFP28 DWDM PAM4 80Km LC Transceiver

The HT-100GD-CXX series QSFP28 100G DWDM PAM4 LC QSFP28 DWDM Transceiver module is designed for use in duplex optical data communications. This module is designed for single mode optical fiber and operates at a data rate of 100Gbps at the nominal DWDM wavelength from 1528.77nm to 1565.50nm as specified by the ITU-T. This module can convert 4 channels of 25Gbps (NRZ) electrical input data to 1 channel of 100Gbps (PAM4) optical signal, and also can convert 1 channel of 100Gbps (PAM4) optical signal to 4 channels of 25Gbps (NRZ) electrical output data. The electrical interface of the module is compliant with the OIF CEI-28G-VSR and QSFP28 MSA. It is designed to deploy in the DWDM networking equipment in metropolitan access and core networks.

Notes:

1, The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal below this average power level

2, Module receiver LOS characteristics are realized by monitoring the DC current of the high-speed photodiodes. Preliminary LOS threshold limits are shown in the table
