Huawei sets new benchmarks for optical transport networks

Company introduces the industry's first 10 petabit all-optical switch prototype, first 400Gbps long-haul DWDM system, and Ethernet-over-OTN interoperability

Middle East - March 13, 2012: Huawei, a leading global information and communications technology (ICT) solutions provider, has recently showcased 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) as well as the world's first 400Gbps long-haul DWDM system.

The challenges of delivering high-bandwidth content to large numbers 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," notes Cai Changtian, President of Transport line, Huawei.

According to consultancy firm Ovum, Huawei ranked No. 1 in the global optical network market, WDM/OTN market, and 40G network market as of Q3 2011. By the end of 2011, Huawei had deployed over 15 commercial and 50 trial 100G networks.

Industry's first 10 petabit all-optical switch prototype (the PPXC)

Huawei's 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.

Industry's first 400Gbps long-haul DWDM system

Huawei's 400G DWDM marks another major breakthrough in the high-speed transport field. The system provides a capacity of up to 20 Tbit/s over a single fiber (C-band) and a transmission distance spanning 1,000 km without electrical regeneration. The DWDM 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.

Ethernet-over-OTN interoperability

Employing Huawei's terabit OSN product, the successful demonstration of Ethernet-over-OTN interoperability tests were conducted by the Optical Internetworking Forum (OIF) in alliance with Deutsche Telekom (DT) and KDDI R&D Laboratories Inc. (KDDI Labs). The tests showcased the multi-vendor interoperability of Ethernet services in a multi-carrier environment over OTN transport. The demonstration focused on both data and control plane technology, including: GE/10GE EPL/EVPL service interoperability, ODUk/ODUflex mapping and encapsulation, ODUk/ODUflex overhead interoperability, ODUk SNCP cross-domain protection, and OTUk ENNI interoperability.

Huawei's latest transport network solutions were unveiled during OFC/NFOEC 2012.
