ZTE Corp. (0763.HK / 000063.SZ) used this week's Next Generation Optical Networks Conference in Nice, France, to unveil the ZXMP M721 CX66A, which it describes as an enhanced Optical Transport Network (E-OTN) platform for the metro edge. The company says its E-OTN approach leverages innovation in such aspects as internal mapping and multiplexing, forwarding, algorithms, interfaces, and other aspects of OTN to lower latency to levels commensurate with the requirements of 5G fronthaul/backhaul and other emerging services.
The ZXMP M721 CX66A is designed to provide packet-optical transport capabilities in a compact package. It supports ROADM and centralized electrical cross-connection capabilities that offer non-blocking cross-scheduling of optical channel data units (ODUks), packets, and virtual containers. It offers a variety of transmission rates based on multiple high-order modulation methods formats, with a top rate of 200 Gbps. It offers support of software-defined networking (SDN) concepts to promote intelligent and open network architectures.
"The ZXMP M721 CX66A effectively promotes end-to-end OTN deployment, and will accelerate service development in the 5G and big video era," said Chen Yufei, general manager of optical transmission products at ZTE.
Among the E-OTN parameters are "OTN-lite" and "super-low delay technologies" that ZTE asserts will enable the ZXMP M721 CX66A to support 5G network deployments. In a separate press statement, the company also touted 5G network slicing technology as an E-OTN attribute. ZTE believes E-OTN will benefit both 5G and data center interconnect applications that require high-speed, low-latency transport.
