Huawei has rolled out its all-optical switching network architecture that the company said supports any network topology. According to the company, the all-optical switching network technology offers cost-effective and energy-efficient transport based on all-optical switching by eliminating the need for optical-electrical-optical (OEO) conversion or electrical switching.

Huawei added that it has found a way to solve the industry-wide challenge of switching multi-dimensional and multi-wavelength optical bursts through the use of the optical time slot interchange (OTSI) technology that enables any-topology, all-optical contention-less networking.

Additionally, Huawei demonstrated high-speed, real-time 100Gb/s optical burst transceiving. The all-optical switching network architecture is also compatible with traditional wavelength division multiplexing (WDM) and reconfigurable optical add/drop multiplexer (ROADM) networks.

The architecture makes further advances in any-topology networking and coherent transmission for optical bursts, the company indicated.
