ZTE to deploy world's largest OTN network for China Mobile
ZTE Corp. (0763.HK / 000063.SZ) says that it has won a contract from China Mobile to build what the company asserts will be the world’s largest OTN network. The contract covers China Mobile’s western network project, part of the service provider’s phase-13 centralized procurement for inter-provincial backbone transport network equipment.
The new OTN network will cover 19 provinces of China, with a total link length of 53,828 km. ZTE says it will provide different coding modes to meet long-haul, medium-haul, and short-haul transmission scenarios. The company states its Beyond-100G Flex Shaping algorithm will be used to achieve multi-point optimization on the optical and electrical layers.
China Mobile is in the midst of an OTN upgrade that will affect its entire nationwide network. The upgrade effort is split into two parts, one each for China Mobile’s eastern and western networks. ZTE says it has supported China Mobile’s western network infrastructure for some time, including the construction of a pair of 100G OTN western networks (see "ZTE trumpets China Mobile 100-Gbps OTN awards"). Those fiber networks covered 20 provinces and municipalities across China and covered 7,729,100 square km, about 80% of the land area of China.
