8.Application scenarios

Core Value of Application Scenario Deployment Method

The DWDM metropolitan core ring is deployed at the intermediate node of the metropolitan core ring, enabling flexible up and down of local services with four consecutive wavelengths at a low cost, without the need to deploy large multiplexing and demultiplexing equipment

The intermediate node of the long-distance trunk line is located at the intermediate station of the long-distance trunk line, and a continuous set of 4 wavelengths is sent to the local area to save the wavelength resources of the trunk line and avoid the construction of large terminal stations

Fixed OADM nodes are used as fixed 4-channel OADMs at sites that do not require reconfigurability, providing low-cost wavelength uplink and downlink solutions for collaborative networking with ROADM networks

Cascaded expansion networking uses MI/MO interfaces to cascade multiple MR4 boards, constructing 8/12/16 channel OADM nodes that support smooth expansion from 4 channels to more channels, adapting to business growth needs

The regional aggregation node is located at the regional aggregation point and routes 4 wavelengths down to the local business access ring to achieve wavelength level business scheduling between the backbone layer and the access layer

9.Maintenance and ordering information

Project Information

Component code TN11MR4

Ordering instructions: When placing an order, it is necessary to confirm the wavelength grouping requirements.MR4 supports a fixed configuration of 10 consecutive 4 wavelengths

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 4 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 and can appropriately reduce the proportion of spare parts, but key nodes can be configured with spare parts

Warranty service standard: The warranty period is 1 year, and technical support can be obtained through authorized Huawei distributors

Application suggestion:

This board is a 4-channel OADM component for the DWDM core/aggregation layer in the OSN 9800 wavelength division system. It is particularly suitable for scenarios that require fixed wavelength planning and continuous 4-channel uplink and downlink, such as intermediate nodes in urban core rings, intermediate stations in long-distance trunk lines, and regional aggregation nodes. For scenarios that require more channels, smooth expansion can be achieved by cascading multiple MR4 boards. In conjunction with the iMaster NCE intelligent control system, unified management and operation of the core layer optical network can be achieved. For scenarios that require random wavelength configuration or optical layer ASON support, TN11MR2 is a more suitable choice.
