DCO 800G/400G/200G/100G DWDM Coherent Transceiver丨C-LIGHT

DCO 800G/400G/200G/100G

C-LIGHT provides a full portfolio of DWDM DCO Coherent Transceiver products, covering rates from 800G DCO, 400G DCO, 200G DCO, and 100G DCO. This integrated wavelength division solution combines high-capacity transmission with intelligent control. It enables dynamic software-based adjustment of optical signals, allowing multiple high-speed channels to be transmitted simultaneously over a single fiber for ultra-long-haul, large-bandwidth data transport. Like equipping fiber with an intelligent, multi-lane highway system capable of adaptive speed management, it helps customers efficiently build flexible, low-latency backbone networks.
