ZTE unveils optical transport network device for metro edge layer

ZTE Corp., a provider of telecommunications equipment and network systems, has released the ZXMP M721, a compact optical transport network (OTN) metro edge layer device designed to enable future-proof, end-to-end metro transport networks.

ZTE Corp., a provider of telecommunications equipment and network systems, has released the ZXMP M721, a compact optical transport network (OTN) metro edge layer device designed to enable future-proof, end-to-end metro transport networks.

The trend toward all-IP telecommunications services, the evolution of IP networks, fixed/mobile network convergence, and cluster router deployment present network challenges and require that a transport network with multi-service bearing capability, higher bandwidth, and adaptability to a MESH typology structure. In response to these trends, ZTE released its iOTN transport platform, including the ZXONE 8000, ZXWM M920, and ZXMP M820 series products. Integrated with WASON, PXC, L2 switching, and OTN technology, these products can meet various transmission requirements, from the long-distance backbone layer to the metro layer.

With the large-scale commercial deployment of 3G, LTE, IPTV, and broadband access services and the development of new concepts, such as the Smart City, the Smart Grid, the Internet of Things, and tri-network integration, operators’ bearer networks, in most cases, require substantial development to be able to deliver these new services, says a company representative. The ZXMP M721 was developed to help solve these challenges.

This latest addition to the iOTN product family enables ZTE to provide global operators with complete end-to-end (E2E) OTN solutions from the metro edge layer to the metro core and backbone layers. The ZXMP M721’s networking technologies--including fast E2E service provisioning, E2E service dispatching, E2E OAM (operation, administration, and maintenance), and E2E 1588 V2 time synchronization--can help ZTE deliver a unified, future-proof E2E OTN metro transport network.

"We believe ZTE’s ZXMP M721 is the best and smallest integrated device in the industry,” says Fan Xiaobing, general manager of ZTE’s Bearer Network product line. "Featuring large capacity, intelligence, and high reliability, it can help global customers to build controllable intelligent optical networks that extend to the metro edge and lead the growing development of E2E OTNs.”

Measuring 1U or 2U high, the ZXMP M721 compact OTN device supports DC and AC power supply, and includes a range of new technologies to meet the changing requirements of metro edge layer networking.

Its network control processor and power board support 1+1 backup; it supports access at any rate from 100Mbit/s to 4.25Gbit/s; it enables aggregation of 4~22 services and smooth upgrade to one optical channel; it supports L2 switching with complete OAM function and 1588 V2 time synchronization; and it can support up to 8 wavelengths of CWDM 10G transmission to enable the integrated and seamless interconnection of CWDM and DWDM.
