Future-Oriented IP Services Boost Operators' Ability for Service Delivery

Optical network is the backbone of the entire telecom network. With the advancement of optical component and silicon technologies, optical network is witnessing a shift from single point-to-point topology to ring and mesh topologies, accompanied by increased automation of equipment.

Large-Capacity ODUk Digital Cross Connection

In April 2010, ZTE launched ZXONE 8000 series, a large-capacity digital cross-connect equipment, to cope with the requirements of bandwidth and large-granule service grooming in metro network. The equipment can help operators build intelligent and flexible transport grooming network at IP granularity, thus adapting to future metro networks.

ZXONE 8000 can perform high-speed and intelligent grooming of services at granularities of ODU0/1/2/3 and provide OTN digital cross-connect capacities ranging from 800Gb to 1.6Tb and 3.2Tb. It implements non-blocking digital cross connection at granularities of ODU0/1/2/3.

Frost & Sullivan states that ZXONE 8000 has reliable system architecture. Its cross-connect unit employs advanced N:M protection mode to identify cube-level failure rate, resulting in much higher equipment security compared to traditional N+N protection mode with square-level failure rate.

“ZXONE 8000’s other salient features include: flexible access of varieties of services like STM-1/4/16/64/256, POS, GE/10GE/40GE, OTU1/2/3, DVB, ESCON, FC-N (N=1, 2, 4, 8, 10); dual-plane intelligent control via loading WSON to accelerate service provisioning; multiple restoration paths for critical services to enhance service survivability and boost network utilization,” analyzed Fox Hu, consulting manager of ICT practice, Frost & Sullivan.

Greener and Simpler

“With the vastly increased investment on 3G services, operators will come under increasing pressure to drive down network investment cost and improve ROI,” cited Cheney Ji, consultant of ICT practice, Frost & Sullivan.

Green network results in lower operational cost. ZXONE 8000 can be deployed in core layer optical network. It recorded power consumption of 34.650W and 27.455W per 10G bandwidth respectively under separate tributary and line mode and transponder mode. The service processing system enables full utilization of bandwidth reducing network construction and operational cost.

Intelligent service control helps to lower maintenance cost. By integrating GMPLS control plane to the network, ZXONE 8000’s service processing system (ROAMD and digital cross-connect system) can implement highly intelligent service operation. Operators can perform hierarchical QoS management, implement network-level service restoration and balance link load; making the network more intelligent and easier in service control and maintenance. As a result, the network operation and maintenance cost can be reduced.

According to Frost & Sullivan, core layer optical transport network market has high technical barrier. ZTE is expected to succeed in gaining access to this high-end optical network equipment market with ZXONE 8000. Its outstanding system architecture and performance can help operators build high-performance and large-scale intelligent optical transport network, accommodating development of future metro networks.
