SHENZHEN, China -- Huawei, a leading global information and communications technology (ICT) solutions provider, today announced that it will work closely with the Sichuan Branch of China Mobile, Sichuan Mobile, to deploy WDM-based full-service metropolitan bearer networks in over 10 cities across Sichuan Province, including the capital, Chengdu. Aiming to significantly improve the transmission capabilities of existing metropolitan area networks (MANs) in Sichuan, the project represents an important step towards fulfilling the "Broadband China" strategy laid out by the national government.

In the face of rapidly growing FTTx, LTE, and leased line services, Sichuan Mobile estimates that the bandwidth demand from its metro aggregation sites will exceed 100G over the coming three years. Besides the bandwidth challenge, service provisioning is slow and network maintenance is complex on existing MANs which transmit a wide range of services (such as TDM, Ethernet, and SAN; with 2M-10G rates) and comprise a great variety of devices (PDH/SDH/MSTP/switches/routers).

To overcome these challenges, Sichuan Mobile decided to deploy full-service metropolitan bearer networks using Huawei's Packet Optical Transport System (POTS) solution. Based on a unified switching platform, the solution can more efficiently deliver high-bandwidth multi-service transmission. The case-shaped 400G WDM device adopted by the solution is ideal for MAN equipment rooms, which are typically crowded with equipment and have limited power supply resources. At only 5U high, it is much smaller and more energy efficient than a traditional rack-mounted device of the same capacity. The innovative device supports AC and DC power and can be flexibly deployed in various scenarios.
