7.Application scenarios

Core Value of Application Scenario Deployment Method

The wavelength downlink nodes of the ring network/chain network are deployed at the intermediate nodes of the ring network or chain network to achieve dynamic wavelength downlink support for any wavelength combination and downlink from any port, flexibly adapting to business change requirements

The ROADM node supplements the downlink as a downlink expansion unit in the ROADM node, increasing the density of downlink ports to provide 8 downlink ports, supporting independent VOA adjustment for each wavelength, and optimizing reception performance

Optical layer ASON network nodes serve as manageable downstream 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 downstream channel power and spectrum, achieving optical layer visualization

The 40 wave DWDM system is perfectly compatible with existing fixed grid systems deployed in traditional DWDM systems with a 40 wave @ 100GHz interval, achieving smooth upgrades

8.Maintenance and ordering information

Project Information

Component code TN12WSD9

Ordering instructions: When placing an order, it is necessary to confirm the working band (C-band) and channel spacing (100GHz fixed grid)

On site operation supports hot plugging, and anti-static wrist straps should be worn during operation.Pay attention to cleaning the fiber optic connectors

After the installation of VOA configuration, VOA attenuation calibration needs to be performed through the network management to ensure control accuracy

Two monitoring ports can be used to connect to a spectral analyzer for real-time monitoring of output spectra

After testing and verifying installation, insertion loss testing, port connectivity testing, wavelength scheduling function verification, and VOA function verification need to be conducted

Spare parts management, as the core board of ROADM nodes, is recommended to configure spare parts at critical network nodes
