China Telecom’s View of the All Optical Network

Optical network technologies develop rapidly in China. Revenues from optical products in China account for roughly half of the worldwide market and include systems, devices, components and fiber. Nowadays, with the massive deployment of 100G, FTTx and ROADM devices, the “all optical” target has never been closer. Meanwhile, challenges have arisen. The continuous growth of traffic from data centers and residential users has pushed the optical network needs to 400G for backbone and 10G PON for access. The next generation 5G mobile networks cannot exist without novel optical solutions to carry its backhaul and fronthaul. This presentation will focus on the current deployment situation of the optical network in China Telecom as well as future goals to meet new services’ requirements.
