Huawei, a provider of next-generation telecommunications network offerings for operators, has released the OBTN (Optical Burst Transport Network) prototype, which utilises burst technology to realise optical layer packet switching.

The company said the evolution towards an all-optical switching network is highly accelerated by the successful development of this prototype.

Led by Huawei, all-optical switching technology OBTN enables convergence of Layer 0 (optical layer), Layer 1 (electrical physical layer) and Layer 2 (link layer), reducing the total OAM of a network.

OBTN is compatible with current wavelength-division multiplexing (WDM) wavelength-switching networks and is able to offer both sub-wavelength and wavelength granularity aggregation.

Sub-wavelength add/drop is realised based on all-optical processing by attaching optical control labels to each optical packet, Huawei said.

Huawei Transport Network president Changtian Cai said the OBTN prototype is a significant milestone in the progress towards the all optical network.

"Huawei views strategic investment in advanced transport technologies as a key foundation to solve its customers’ challenges as networks scale in bandwidth and transition to packet centric topologies," Cai said.
