China’s ZTE Corporation debuted what it says is the world’s first 400G/1T dense wavelength division multiplexing (DWDM) multi-application network device prototype.
Demonstrated at the WDM & Next Generation Optical Networking Forum in Monaco, the company says this device can carry out seven different network applications, depending on a carrier’s requirements.
Here are more details: The 400G/1T DWDM prototype features a multi-subcarrier Orthogonal frequency division multiplexing 400G/1T solution for ultra-long-haul applications. It also is a 16-quadrature amplitude modulation (QAM) solution for metro and local applications. Further, it is a Nyquist WDM solution for long-haul applications.
In separate but related ZTE news, Anite, a U.K.-based wireless-device-testing provider, will team with ZTE to “prove the first TD-LTE/TD-SCDMA Inter-Radio Access Technology (RAT) conformance test cases.”
The TD-LTE/TD-SCDMA Inter-RAT test cases are part of Anite’s Conformance Toolset for LTE conformance testing. With the largest number of protocol conformance test cases validated by the Global Certification Forum (GCF) across all band combinations, Anite’s Conformance Toolset reportedly is the first solution in the industry to support TD-LTE/TD-SCDMA Inter-RAT test cases.
“The TD-LTE/TD-SCDMA Inter-RAT conformance test cases will enable those chipset manufacturers and handset vendors who are developing dual-mode TD-LTE/TD-SCDMA devices to begin testing immediately,” Unite adds. “The test cases will accelerate the maturity of devices and provide a roadmap for the start of formal conformance testing prior to commercial network launches. Dual-mode handsets will allow users seamless access to high speed data services offered by both TD-LTE and TD-SCDMA – the 3G standard widely deployed in China.”
"Anite’s unrivalled technical expertise in TD-LTE and TD-SCDMA made them a clear choice to be our key collaboration partner," comments Huoling Li, product manager of ZTE’s LTE chipset product line.
