The CFP2-DCO coherent transceiver supports flex-grid DWDM tuning and provides 200GBase-DCO throughput up to 80km over single-mode fiber (SMF) using a wavelength of 1528.578-1567.337nm via an LC/UPC connector. It can operate at temperatures between 0 and 70°C. Digital optical monitoring (DOM) support is also present to allow access to real-time operating parameters. It is designed for line-side trunk DWDM data center interconnect (DCI) and OTU4/OTUC1/OTUC2 metro optical transport network.
