T1-QSFP28-100G-DWDM-PAM4-Cxx is designed for use in duplex optical data communications. Designed for single-mode optical fiber, it operates at a data rate of 100Gbps at the nominal DWDM wavelength from 1528.77nm to 1565.50nm as specified by the ITU-T. It 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.
