ZTE broadband metro network solution

Electro-optical cross connection “inducing” higher value


Challenges to IP-based metro transport network


As telecoms networks are in the shift to be packetized and broadband-based, All-IP has been the future development trend of service networks. According to prediction, bandwidth is expected to grow at an annual rate of over 30% in the next five years. The two-layer networking mode “IP over WDM” is gradually replacing the traditional three-layer “IP over SDH over WDM” mode at both backbone layer and metro layer, and the flat architecture enabling carriage of IP packets directly over photonic layer has been an inevitable trend. IP over WDM networking architecture poses new requirements for photonic layer WDM equipments, and WDM layer will take over the networking, service grooming and end-to end circuit monitoring and management functions originally provided by SDH networks.
