ZTE offers seamless upgrade from PTN to POTN

ZTE today released the ZXCTN 6500 300mm T-class large capacity POTN (packet optical transport network) product which provides seamless upgrade from PTN (packet transport network) to POTN.

This product is the first solution for the unified evolution from packet transport network (PTN) to packet optical transport network (POTN) in the industry.

The ZXCTN 6500 300mm T-class supports the integration of PTN and OTN through unified switching, the high efficient transport of L1/L2/L3 services and SDN-oriented control plane architecture. The seamless upgrade from PTN to POTN can simplify complex network layers and significantly reduce the operator’s investments.

Traditional PTN+OTN multi-layer networks have to face lots of problems such as the high cost and the large equipment size. ZTE’s POTN solution can substantially increase the existing PTN’s bandwidth, simplify network layers, save valuable machine room space and allow single network to carry multiple applications.

Compared to traditional solutions, the new product can save 50 to 60 percent energy consumption, 47 to 65 percent space occupied, 70 percent service deployment time and 50 percent time cost for fault diagnosis. Furthermore, the new product makes it possible for flexible scheduling and arbitrary conversion of the PTN packet traffic and the ODU sub-wavelength traffic, thereby optimizing the existing network’s multi-layer architecture.

“We’re particularly excited about the release of ZXCTN 6500 300mm T-class as it can effectively solve the problems of operators and represents the future development trend of packet transport networks,” said Xu Ming, vice president, ZTE.

“With mature standards and production chain, I believe POTN will be widely deployed with a large scale in 2014,” added Ming.
