This 100G QSFP-DD Coherent ZR+ Tunable Transceiver is a high-performance digital coherent optics (DCO) module engineered for long-reach data center interconnect (DCI) and metro optical transport networks. Fully compliant with Open ZR+ MSA and QSFP-DD MSA standards, it delivers 100Gbps payload transmission over single-mode fiber (SMF) with a tunable C-band laser (1528.77~1567.13nm), eliminating the need for additional transponder/muxponder equipment and reducing network CAPEX and OPEX significantly.
