The DTM-100G2 is a single-slot 100G coherent transponder module for Ciena's Z-Series Packet-Optical Platform. Cisco ® QSFP28 100G ZR extends 100GbE coherent links from QSFP28 ports reaching up to 80km over dark fiber and up to 300km over amplified Dense Wave Division Multiplexing (DWDM) links. 6T quantum-safe encryption solution on the Waveserver platform was designed with this in mind, supporting QKD system interworking and NIST-certified PQC algorithms. It is fully compliant to the IEEE 802. 3™-2022 100GBASE-ZR standard, ensuring interoperability with other solutions.
