• Intelligent Optical Network WSON

ZXWM M920 supports GMPLS/WSON control plane load, can realize rapid automatic route discovery. Strong ability for automatic resource discovery. Versatile resource management functions and fast end-to-end service provisioning and so on.

• Powerful Electrical-Optical Mixed Switching

ZXWM M920 is an intelligent WDM product with the most powerful electrical-optical mixed switching function, it can simultaneously support multi-granularity services dispatching in optical layer, electrical layer and the data L2 switching; optical-layer, electrical-layer and L2 layer can work together to randomly dispatch services from electrical layer to optical layer, which improves network flexibility.

• IWF (Integrated Wavelength Feedback) Patented Technique

Combination of patented wavelength centralized monitoring technique and precise temperature control further guarantees the wavelength stability of 50GHz wavelength spacing system. Realize smooth system upgrading from 100GHz spacing to 50GHz spacing.

• APO (Auto Performance Optimization): Secure and Reliable Optical Power Auto-balancing Technique

Embedded sub-network-level performance optimization algorithm is used to automatically establish and retain the optimized status of system optical performance, as exemplified by OSNR, maintain optimal overall system performance, drive down maintenance cost and improve maintenance efficiency, applicable to WDM system with frequently changing fiber parameters.

• Leading Protection Schemes

ZXWM M920 can provide multiple and effective protection modes: Optical subnet connection protective switchover (OSNCP); Unidirectional optical line protective switchover (ULSR); Unidirectional optical channel protective switchover (UPSR); Bidirectional optical line share protective switchover (BLSR); Bidirectional optical channel share protective switchover (BPSR); 1: N tributary protection etc. which with the switching time shorter than 50 ms.

• Power Service Access And Aggregation Ability

ZXWM M920 supports transparent transmission of optical signals in multiple formats, such as STM-N (N=1, 4, 16, 64,256), POS, GbE/10GE, ATM, ESCON, FICON and FC, which protect user’s benefit and provide an ideal means for network expansion.

Customs experience
