8.Maintenance and ordering information

Project Information

Component code TN96WSD9

Ordering instructions: When placing an order, it is necessary to confirm the working band (extended C-band) and flexible grid configuration requirements

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

Core Summary:

TN96WSD9 is a flagship 9-port wavelength selective switch demultiplexing board for ultra 100G/400G/800G flexible grid networks in the OSN 9800 platform, representing the highest level of technology in the WSD9 series, achieving two core enhancement features: 12.5GHz fine flexible grid and extended C-band.

Core values and positioning:

Ultimate Spectrum Efficiency: With a minimum slice size of 12.5GHz, it supports fine spectrum allocation for any rate business from 100G to 1.6T.Compared to 50GHz fixed grid, it can improve spectrum efficiency by more than 50%.

Extended C-band coverage: Operating wavelength range of 1528.8-1567.6nm, supporting 96 wave @ 50GHz or higher density DWDM systems to meet future high-capacity transmission needs.

Refined power management: Independent 0-15dB VOA adjustment for each downstream wavelength, allowing for remote and precise adjustment of received power, optimizing receiver performance.

Intelligent operation and maintenance support: Provides 2 online monitoring ports and comprehensive alarm monitoring functions, supports optical layer ASON, and provides a foundation for intelligent optical networks.

The essential difference from other models in the same series:

The 12.5GHz slice granularity of TN96WSD9 is a revolutionary improvement, shifting spectrum management accuracy from the"extensive" 50GHz to the"refined" 12.5GHz.At the same time, expanding C-band support to cover 96 wave high-density systems is truly a next-generation WSD9 board for the future.

Application suggestion:

This board is the downstream core component for over 100G flexible grid networks in the OSN 9800 wavelength division system, particularly suitable for scenarios that require fine spectrum management, multi rate hybrid transmission, and large capacity business aggregation, such as national backbone network core nodes, large data center interconnection hubs, next-generation ROADM nodes, etc. When deploying, it is necessary to combine the iMaster NCE intelligent control system to achieve automated operation and maintenance of the optical layer and dynamic management of spectrum resources. For existing networks that still use fixed grids, TN12WSD9/TN13WSD9 is a more cost-effective choice.
