Huawei has unveiled its latest advancements in the field of optical communications including the release of the industry’s first 10 petabit all-optical switch prototype (the PPXC) and the first 400Gb long-haul DWDM system.

Cai Changtian, president of transport line, Huawei, said: “The challenges of delivering high-bandwidth content to a large number of mobile users is evolving these types of transport network technologies towards all-optical switching; which can process optical signals directly and cross-connect services of any granularity at the optical layer. With fiber transmission capacity reaching 100G/400G, improvements in core switching nodes are also providing higher capacity with lower power consumption on transport networks.”

“With accelerated development of ultra-broadband networks, these types of all-optical switching solutions and upgrades to network bandwidth will play an indispensable role in backbone transport scenarios,” he said.

The new PPXC prototype uses optical burst technology to provide flexible non-blocking switching of multi-granularity services. It allows for simultaneous high-resolution 3D interactions among 100 million people, as well as simultaneous voice services for billions of people.

Compared with traditional electrical switches, the all-optical prototype is smaller in size and consumes less power. It provides ultra-large switching capacity in an energy-efficient way, supporting the implementation of ‘green’ optical networks, a statement from the company said.

Huawei’s 400G DWDM provides a capacity of up to 20 Tbit/s over a single fiber (C-band) and a transmission distance spanning 1,000km without electrical regeneration. The technology goes beyond 100G with the rapid expansion of broadband services.

Bolstered by the mature technologies available, the 400G DWDM is regarded as the next-generation DWDM system for deploying ubiquitous ultra-broadband networks. The prototype can be applied over the Huawei WDM/OTM platform to allow for smooth evolution from 40G/100G, the statement said.

Employing Huawei’s terabit OSN product, the demonstration of ethernet-over-OTN interoperability tests were successfully conducted by the Optical Internetworking Forum (OIF) in alliance with Deutsche Telekom (DT) and KDDI R&D Laboratories (KDDI Labs), it said. – TradeArabia News Service
