ZTE Launches Unique Multi-Application 400G/1T DWDM Prototype
By Carolyn J Dawson
ZTE (News - Alert) Corporation has introduced its unique 400G/1T dense wavelength division multiplexing (DWDM) multi-application network device prototype. The prototype was showcased by the major telecommunications equipment and network solutions provider, ZTE, at the 16th WDM & Next Generation Optical Networking Forum, held in Monaco.
Seven varied network applications can be executed by the device as per the different needs of the carriers.
Equivalent bandwidth capable of operating with a wide range of network applications is offered by the 400G/1T DWDM prototype. Extremely-long-haul applications can utilize the prototype’s Orthogonal frequency division multiplexing 400G/1T offering, supporting several subcarriers.
Metro and local applications can benefit from the prototype’s 16 quadrature amplitude modulation offering, which also includes the maximum bandwidth utilization rate in the industry. The product also offers long-haul applications a Nyquist WDM offering.
“ZTE is fully prepared to deploy solutions, products and services for the large-scale commercial global rollout of 100G and ultra-100G,” said Chen Yufei, general manager of the Bearer Network Product Line at ZTE.
Apart from C-band 80-wavelength applications, the 100G DWDM/ optical transport network (OTN) system from ZTE also supports regular PM-QPSK code pattern adjustment and coherent detection. The most powerful 100G transport capability is available in the industry, which uses the most sophisticated soft decision forward error correction technology around.
Revolutionary bearer network solutions, devices and services are offered by ZTE to enterprises across the globe. In 2010, a complete range of 100G bearing offerings was introduced by ZTE for the first time in the industry. ZTE’s portfolio of 100G products included switches, routers, WDM OTN equipment and end-to-end solutions from edge layer to core layer.
The unique 1Tb/s DWDM prototype system, along with its test output, was showcased by ZTE for the first time in the world in July 2011 at the Opto-Electronics and Communications Conference, held in Taiwan. ZTE has also filed several patents in 100G and ultra-100G technologies, which include 100G optical modules, framer, chip, system and other aspects of the technology.
At least 20 patents of ZTE are presently in the application process.
