Huawei Develops All Optical Switching

Huawei showcased prototypes of an All-Optical Switching platform at this week's OFC/NFOEC 2013 event in Anaheim, California. The Optical Burst Transport Network (OBTN) prototype joins a Petabit Photonic Cross-Connect (PPXC) prototype showcased at earlier OFC/NFOEC events. This new All-Optical Switching Network architecture makes further advances in any-topology networking and coherent transmission for optical bursts.

Huawei said All-Optical Switching Network technology could eliminate the need for Optical-Electrical-Optical (OEO) conversion or electrical switching. Huawei solves the challenge of switching multi-dimensional and multi-wavelength optical bursts through the use of Optical Time Slot Interchange (OTSI) technology. This enables any-topology, all-optical contention-less networking. 

Huawei is also demonstrating 100 Gbps optical burst transceiving, an industry first.  

Huawei noted that its All-Optical Switching Network architecture is compatible with traditional WDM and Reconfigurable Optical Add/Drop Multiplexer (ROADM) networks.
