6.Application scenarios

Core Value of Application Scenario Deployment Method

DWDM line interfaces are deployed on the line side of OTM/OLA/ROADM sites, connecting devices with optical fibers to provide standard optical interfaces, integrating OSC processing, and reducing system complexity

The fine adjustment node of optical power is used at sites that require precise control of input fiber power (such as high nonlinear links) to remotely adjust output power through VOA, optimize nonlinear effects, and improve system OSNR

Intelligent optical layer monitoring points are deployed at key nodes in the network, utilizing MON ports and built-in optical power monitoring to construct an intelligent optical layer for real-time visualization of optical layer performance, supporting automatic power balancing and rapid fault location

The hybrid amplification structure interface is used in conjunction with an optical amplifier (OA) to provide interface and power regulation, simplifying the optical path connection of the hybrid amplification system and facilitating centralized control
