Telefonica Mexico Movistar (TMM) said its beyond 100G optical transport network (OTN) has gone live covering three core cities: Mexico City, Monterrey and Guadalajara.

TMM, second largest mobile operator in Mexico, provides telecommunications services for over 25 million users.

The telecom operator’s existing OTN of TMM has encountered pressure and challenges due to large-scale deployments of 4G networks and rapid growth of bandwidth demand. Telefonica Mexico Movistar deployed ZTE’s ZXONE 9700, the E-OTN device with extra capacity in OTN, to solve these problems.

ZTE said the ZXONE 9700 can scale up to 400G in the future by employing multi-service unified cross-connect platform, flex grid, and beyond 100G high-order modulation technologies. It can solve the bottleneck of OTN electrical cross-connect capacity and meet the ultra-high bandwidth requirement of core rings in the major cities.

Telefonica Mexico Movistar is using the WASON protection solution, with a function of supporting smooth upgrade to SDN, to enhance the network reliability and security. The loaded OTDR, OSA, and Ethernet service aggregation and processing functions can reduce the costs of the operation and maintenance (O&M) and network construction.

According to the latest report of GlobalData, ZXONE 9700, the E-OTN device of ZTE, is the No.1 in the class in terms of OTN and packet switching capacity and client interface density.

ZTE has deployed over 300 optical networks across the world, with the total length of network fibers exceeding 300,000 km.

According to Ovum’s latest market share data, among the top 10 telecom equipment vendors in Q2 2017, ZTE’s Optical Networking (ON) products had largest gain in market share growth on a rolling 4-quarter basis, and ZTE’s ON market share is ranked in second place globally.
