7.Application scenarios

Core Value of Application Scenario Deployment Method

The mixed rate flexible grid ring network/chain network deploys flexible grids at intermediate nodes in ring or chain networks that need to simultaneously carry mixed rate services such as 100G/200G/400G to support the bandwidth requirements of different rate services (100G occupies 1-2 slices, 200G occupies 2-3 slices, 400G occupies 3-4 slices), maximizing spectrum utilization efficiency

The evolution of nodes from fixed grid to flexible grid requires the deployment of nodes with flexible grid capability in the existing 80 wave @ 50GHz fixed grid network, which is compatible with existing 50GHz fixed grid devices and supports flexible grid evolution to protect network investment

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

8.Maintenance and ordering information

Project Information

Component code TN16WSD9

Ordering instructions: When placing an order, it is necessary to confirm the working band (C-band) and whether flexible grid support is required

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:

TN16WSD9 is a 9-port wavelength selective switch demultiplexing board for hybrid rate transmission enhancement in the OSN 9800 platform.It adds Flex Grid support on the basis of TN13WSD9, with 50GHz as the slice unit, and each channel can continuously occupy 1-8 slices.

Core values and positioning:

Flexible Grid Enable: Compared to the fixed 50GHz grid of TN13WSD9, TN16WSD9 supports flexible grid, which can meet the bandwidth requirements of different speed services such as 100G/200G/400G, significantly improving spectrum utilization efficiency.

Hybrid rate network core: In networks that simultaneously carry multiple rate services, TN16WSD9 can flexibly allocate spectrum resources to avoid bandwidth waste caused by fixed grids.

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

Compact Space Design: Compared to the 76.2mm width of TN13WSD9, TN16WSD9 adopts a 50.8mm width design, saving 33% of slot space.

The core difference from TN13WSD9:

On the basis of maintaining 80 channel capacity, TN16WSD9 has added flexible grid support (50GHz slicing), while reducing the front panel width from 76.2mm to 50.8mm, with slightly optimized power consumption (25.0W vs 25.4W).Choosing TN16WSD9 means obtaining both fixed grid compatibility and flexible grid evolution capability in a compact space.

Application suggestion:

This board is the downstream core component of the OSN 9800 wavelength division system for 80 wave @ 50GHz fixed+flexible grid hybrid networks, particularly suitable for scenarios that require flexible spectrum allocation, compact space design, and multi rate hybrid transmission. During deployment, it is necessary to fully utilize its online monitoring port and VOA adjustment function, combined with iMaster NCE to achieve automated operation and maintenance of the optical layer and dynamic management of spectrum resources. For new networks that require finer spectrum slicing (12.5GHz) or extended C-band, it is recommended to consider TN96WSD9.
