3.Core functional characteristics

Functional Module Technical Description System Value

Wavelength uplink and downlink enable the uplink and downlink functions of two specific CWDM wavelength channels, while other wavelengths can be directly routed locally or inserted with specific wavelength services without the need for complete wavelength splitting, saving costs

Wavelength independent configuration supports any combination of 2 CWDM channels, with no fixed up/down rule restrictions, greatly improving network configuration flexibility.Users can freely choose up/down wavelengths according to business needs

Cascade expansion capability provides MI/MO cascade interface, which can be connected to another OADM board to achieve channel expansion.It supports smooth expansion from 2 channels to more channels, adapting to network expansion needs

The wavelength query function supports querying the configuration information of upstream and downstream wavelengths, making it easy for operation and maintenance personnel to grasp the current channel configuration status

CWDM supports a full band working wavelength range covering 1271nm~1611nm, and supports all 18 waves of CWDM compatible with all standard CWDM wavelengths, meeting the full band application requirements of coarse wavelength division systems

Passive design is mainly based on passive optical devices to achieve functions, with a power consumption of only 0.2W, ultra-high reliability, zero heat generation, and long service life, without the need for additional heat dissipation

7.Application scenarios

Core Value of Application Scenario Deployment Method

CWDM metropolitan access ring is deployed at various nodes of the metropolitan access ring to achieve flexible up and down of wavelength level services at a very low cost, without the need to deploy large multiplexing and demultiplexing equipment

Enterprise dedicated line access is provided at remote nodes close to enterprise users, offering a low-cost and fast deployment solution for connecting two dedicated line services up and down

The base station forward/backward transmission is on the 5G base station side, and CPRI/eCPRI services are routed up and down to the CWDM system to meet the low-cost and high bandwidth requirements of 5G forward transmission, supporting 12 wave/18 wave CWDM systems

Video surveillance is transmitted back to monitoring points in safe cities, enabling low-cost, long-distance video transmission of video streaming services through multiple monitoring points

Cascaded expansion networking uses MI/MO interfaces to cascade multiple CMR2 boards, constructing 4/6/8 channel OADM nodes that support smooth expansion from 2 channels to multiple channels, adapting to business growth needs

8.Maintenance and ordering information

Project Information

Component code TN11CMR2

Ordering instructions: When placing an order, it is necessary to confirm the wavelength configuration requirements for the up and down channels.CMR2 supports any combination of 2 CWDM 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

Special note: Support for 1271nm wavelength can be achieved by connecting third-party devices, although the device itself does not provide a 1271nm OTU board
