8.Application scenarios

Core Value of Application Scenario Deployment Method

The DWDM metropolitan core aggregation node is deployed at the middle node of the metropolitan core ring to achieve flexible up and down of 8-channel wavelength level local services at low cost, avoiding the construction of large terminal stations

The interconnection of regional data centers is located at the exit of the regional data center, providing high-density and low-cost DCI interconnection wavelength up and down solutions for 8 wavelengths to local devices

The intermediate communication station of the trunk line is located at the intermediate station of the long-distance trunk line.A continuous set of 8 wavelengths is sent to the local business network to save the wavelength resources of the trunk line and simplify the station configuration

Expanding fixed OADM nodes as fixed OADM nodes, combined with MR4/MR2 and other technologies, to build a flexible network with hybrid uplink and downlink capabilities that meet the requirements of different wavelength quantities

Cascaded expansion networking uses MI/MO interfaces to cascade multiple MR8 boards, constructing 16/24/32 channel OADM nodes that support smooth expansion of channel numbers to meet business growth needs

9.Maintenance and ordering information

Project Information

Component code TN11MR8 (specific version such as TN11MR8-XXX represents specific wavelength grouping)

Ordering instructions: When placing an order, it is necessary to confirm the wavelength grouping requirements.MR8 supports multiple sets of continuous 8-wavelength fixed configurations

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

Wavelength configuration does not require on-site configuration.According to the wavelength grouping at the time of ordering, the board has been fixed to correspond to 8 consecutive wavelength channels

If the cascade connection needs to expand the number of channels, it is necessary to correctly connect the MI/MO cascade ports to ensure the correct direction of the optical path

After testing and verifying installation, insertion loss testing, upper and lower channel connectivity testing, and cascading function verification are required

Spare parts management, as a passive component, has high reliability, but critical nodes can be configured with spare parts for quick recovery

Application suggestion:

This board is an 8-channel OADM component for DWDM core/aggregation layer in OSN 9800 wavelength division system, which is particularly suitable for scenarios that require fixed wavelength planning and continuous 8-channel uplink and downlink, such as intermediate nodes in urban core rings, interconnection of regional data centers, and intermediate communication stations in trunk lines. For scenarios that require more channels, smooth expansion can be achieved by cascading multiple MR8 boards. In conjunction with the iMaster NCE intelligent control system, unified management and operation of the core layer optical network can be achieved. For flexible nodes that require random wavelength configuration or optical layer ASON support, TN11MR2 is a more suitable choice.
