ZXONE 8000 Series Products

At present, the IP trend of telecom services and evolution of IP network pose enormous challenge to transport network. Meanwhile, viewed from the course of technological progress, domestic and overseas mainstream operators have more and higher requirements such as IP-based, intelligent, green and eco-friendly for WDM technology after point-to-point WDM and OTN. Therefore, iOTN solution integrated with OTN, control plane, λ-level cross-connection at optical layer and L2 switching technology has become the development direction of next-generation optical network. The iOTN technology, adopting IP-based, intelligent and integrated philosophy, can provide the customers with multi-level differentiated solutions.

ZXONE 8000 series products are ZTE's new-generation intelligent transport platform. The current equipment types include ZXONE 8300/8500; new products are to be launched subsequently. The products of this series have the characteristics of large-capacity electrical cross-connection, multi-level service grooming and high-bandwidth transmission, which highly improves the service dispatching capability at metro and toll level.

System Features

  • Diverse Service Access Capability
    ZXONE 8000 series products support access of STM-N, PoS, GE/10GE/40GE, OTU1/2/3, DVB, ESCON, FC-N (N=1, 2, 4, 8 and 10) services, which is not only compatible with traditional services but also meets the requirement of IP-based services.
    ZXONE 8000 supports aggregate of low-rate services such as GE, FC-N and STM-1/4 to 10G/40G services. The Any-type universal service access board introduced can support concurrent access of 16 channels of different services at most to meet the requirement for unified transport of multiple services. ZXONE 8000 series products can effectively increase bandwidth utilization ratio and save wavelength resources.
  • Powerful Service Cross-Connection Capability
    Large-capacity electrical layer cross-connection. ZXONE 8300 CX20/8300 CX30/8500 CX50 can support 0.8T/1.6T/3.2T large-capacity electrical cross-connection respectively and realize ODU0/1/2/3 multi-granule nonblocking electrical cross-connection function; they support service overhead and clock transparent transmission function and is applicable to network core nodes.
    Multi-degree optical layer cross-connection. ZXONE 8000 series products can support 2-10-degree optical layer dispatching and support 40/80/96×10G/40G cross-connect capacity in each degree.
    ODU0 granule cross-connection. ZTE is the only equipment manufacturer that totally supports ODU0 granule cross-connection in the industry. The introduction of ODU0 granule is an important technique to adapt to the all-IP trend of services; it incorporates GE service to OTN system, which improves GE service dispatching and monitoring capability.
    Support L2 layer aggregation. Integration of L2 switching function to WDM equipment can effectively achieve the goal of flat network and simplify network layers.
  • Intelligent Service Dispatching Capability
    Widespread use of WSON. By loading GMPLS-based WSON on ROADM/ODUk switching platform, dual-plane intelligence on optical and electrical layers can be achieved, which shortens service deployment time and provides multiple recovery paths for key services to improve service survivability and increase utilization rate of network resources.
    Fast provisioning of service. The optical layer supports 2-10-degree ROADM, realizing end-to-end automatic configuration; the electrical layer realizes wavelength/sub-wavelength (ODUk) end-to-end automatic configuration via T-level ODUk switching, which remarkably reduce the time required for service provisioning.
  • Stable Service Transmission Capability
    ZXONE 8300 supports 80/96×10G/40G systems respectively; ZXONE 8500 supports160/192×10G or 80/96×40G systems; the max transmission distance of 10G/40G are 5000km/2000km respectively.
    Optical source technologies including out-band FEC, advanced FEC (AFEC), RZ and adaptive receiving together with various amplification modes such as RAMAN amplifier and high-power EDFA are adopted to increase the transmission distance of linear system.
    Support Automatic Performance Optimization (APO) to keep system performance optimized, reduce maintenance cost and adapt to environment parameter changes automatically. Provide Integrated Wavelength Feedback (IWF) patent technology to ensure the stability of wavelength in 50GHz-interval system.
    Support out-band time transmission, which can effectively avoid time inaccuracy caused by physical factors such as dispersion adjustment and route change and improve the stability of time transmission.
  • Smooth Service Upgrade Capability
    Smooth service expansion. Client-side or line-side boards can be added or reduced flexibly as required to protect operators' investment without affecting current service transmission.
    All boards of ZXONE 8300/8500 can be inserted interchangeably, which can save cost of spare parts, reduce maintenance difficulty and facilitate network reform and upgrade.
  • Complete Service Protection Capability
    Diversified optical layer protection. Support optical channel sharing protection (OPCS), multiplex section shared ring protection (OPMS), multiplex section 1+1 protection, equipment-side OUT 1:N protection and optical line protection (OLP). Among them, OPCS is a patent developed by ZTE, which can effectively increase optical channel utilization rate and save wavelength resources.
    Electrical layer protection (ODUk protection). Support ODUk sub-network connection protection (ODUk SNCP), ODUk shared ring protection (EPCS) and ODUk 1:N protection.
    L2-based intelligent Ethernet ring protection (ESR) provides guarantee for uplink aggregate.
  • Flexible Service Monitoring Capability
    All service boards support OTN overhead and so agile monitoring of SM, PM and TCMi overhead can be realized. As the equipment supports TCM overhead, the monitoring on cross-ring cross-area services is more comprehensive.
    ECC/DCC supports OSPF protocol and realizes automatic NE discovery and automatic route configuration functions with good network expandability. It also simplifies network configuration.
    ZXONE 8000 series products support optical and electrical monitoring; the monitoring mode can be selected according to the networking. Optical monitoring adopts 100M transmission with rapid protocol transmission which can meet the management requirement of large networks and improve monitoring efficiency.
  • Complete Equipment Protection Capability
    Support 1+1 hot backup for SNP unit, clock unit and power supply module unit.
    Provide overall protection for cross-connection unit. N:2 protection can be realized for cross-connection unit.
    Intelligent heat dissipation function. FCC intelligent speed regulating heat dissipation modules are located at the bottom and top layers of the shelf. Each FCC has 12 built-in speed regulating heat dissipation fans that support automatic and manual regulation of temperature.
  • High Level of Integration
    The line side and client side are separated to increase board integration. The separation of client side and line side can aggregate various different client-side services to the same line-side board to share the bandwidth, which effectively increases bandwidth utilization rate; the boards on the line side and client side can be combined flexibly so that the spare parts can be reduced from M × N to M + N (M and N mean client-side boards and line-side boards, respectively; M, N>2), which effectively reduces network cost and equipment room space.
    The equipment is green and eco-friendly with low power consumption. It can save 50% power consumption compared with average level in the industry. For a network including ten 80-wavelength sites, it can save 328,500 kWh power every year and reduce 249 ton CO2 discharge.
