Opportunities for WDM devices in the era of 5G, multi-antenna technology has a huge driving force for system bandwidth, and the marginalization trend of WDM/OTN and 5G carrying requirements in metropolitan area network drive the development of WDM devices, while tunable lasers and WDM devices (mainly AWG devices) will be the main challenges for cost performance.
Wei leping pointed out that the first step of the evolution of all-optical network is the optical fiber refinement of transmission link, and the current transmission has realized the deployment of optical fiber and is progressing to 200-400gbps.
The second step is the access network optical fiber, the wiring section and the introduction line and even the desktop are required to achieve optical fiber connection, light into the copper still long way back.
The third step is to introduce optical switching technology into the transmission node, the CTC backbone network will be fully deployed by the end of the year RODAM, travel backbone all-optical network, and continue to the large and small metropolitan area network and access network extension.
