7.Application scenarios

Core Value of Application Scenario Deployment Method

High density ring/chain network nodes are deployed in intermediate nodes of ring or chain networks that require 80 channel capacity, achieving dynamic wavelength routing that doubles the system capacity compared to 40 channel systems, meeting high-density business requirements

The evolution of nodes from 40 waves to 80 waves requires the deployment of network nodes that need to be expanded to 80 waves in the existing 40 wave system to support smooth upgrades and protect existing investments

ROADM node supplements the uplink as an uplink expansion unit in ROADM node, increasing the density of uplink ports to provide 8 uplink ports, supporting independent VOA adjustment per wavelength, and optimizing transmission performance

Optical layer ASON network nodes serve as manageable on road units in networks that require optical layer intelligence features.Optical layer ASON supports automated business scheduling and protection

The online performance monitoring point utilizes two monitoring ports to connect to the Optical Performance Monitoring Unit (OPM) for real-time monitoring of the power and spectrum of the on road channel, achieving visualization of the optical layer

8.Maintenance and ordering information

Project Information
