ZTE Corp. has released the ZXCTN 6500 300mm T-class large capacity POTN product. 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 (optical transport network) through unified switching, the efficient transport of L1/L2/L3 services and SDN (software defined network)-oriented control plane architecture. The seamless upgrade from PTN to POTN can simplify complex network layers and significantly reduce operator's investments. Traditional PTN+OTN multi-layer networks present many challenges such as high cost and 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 a single network to carry multiple applications. Compared to traditional solutions, the new product can save 50% to 60% in energy consumption, 47% to 65% in space occupied, 70% in service deployment time and 50% in 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 (optical data unit) sub-wavelength traffic, thereby optimising the existing network's multi-layer architecture.
