7.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 wavelength level services at low cost for local business, without the need to deploy large multiplexing and demultiplexing equipment

ROADM network supplements the use of fixed OADM at sites that do not require complete reconfigurability, providing low-cost wavelength uplink and downlink solutions for collaborative networking with ROADM network

The intermediate node of the long-distance trunk line is located at the intermediate station of the long-distance trunk line, and the wavelength of the downstream part is saved locally to save the wavelength resources of the trunk line and avoid the construction of large terminal stations

Cascaded expansion networking uses MI/MO interfaces to cascade multiple MR2 boards, constructing 4/6/8 channel OADM nodes that support smooth expansion from 2 channels to multiple channels, adapting to business growth needs

Intelligent optical network nodes serve as manageable OADM nodes in networks that require ASON functionality.Optical layer ASON supports automated wavelength level business scheduling and protection

8.Maintenance and ordering information

Project Information

Component code TN11MR2

Ordering instructions: When placing an order, it is necessary to confirm the wavelength configuration requirements for the up and down channels.MR2 supports any combination of 2 DWDM 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 selection at the time of ordering, the corresponding wavelength channel has been fixed on the board

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
