ZXWM M920

Features

• Excellent 100G transport performance
  The 100G system of the ZXWM M920 uses PM-QPSK coding technology, supports SD-FEC and has excellent B2B OSNR margin indicator, supports more than 1500km radio relay transmission. With the most advanced DSP technology, the dispersion tolerance can be ± 50,000 ps/nm and the PMD tolerance can be 30ps. More than 2500km transmission does not need the dispersion compensation and PMD compensation, which saves the costs and makes the OAM easier.
• Flexible integrated service access capability
  The client supports 100M-100G any service access: the access of STM-N, FE/GE/10GE/40GE/100GE, OTU1/2/3/4, DVB, ESCON and FC services.

　   The universal service access board enables hybrid transmission of the operator’s multiple services.

• Support optical cross-connected and WASON intelligent control plane
  The optical layer supports 2-9-dimensional ROADM. Automatic end-to-end wavelength configuration is supported.
  Support WASON control plane based upon GMPLS protocol. It can support the intelligent control of the network resource and network topology. It shortens the service deployment time, provides multiple recovery paths for the key services, improves the service survivability, and enhances the network resource availability.
• Carrier-class reliability protection
  Based upon rich experiences in engineering and R&D in optical network field for so many years, it supports multiple protection modes, e.g. fiber-class protection, wavelength-class protection and L2 protection.
  * Fiber class: 1+1 line protection, 1+1 optical multiplexing segment protection, and optical  multiplexing shared protection.
  * Optical channel class: 1+1 optical channel protection and optical channel shared protection.
  * L2 layer: ESR protection
• Complete support to time synchronization
  Support in-band/out-band transport 1588V2 and synchronous Ethernet.
