An optical tributary board mainly adds or drops optical signals at sites. The optical tributary board grooms the added signals to multiple optical line boards through the optical backplane to implement dynamic wavelength grooming in multiple line degrees, and performs the reverse process. The optical tributary board applies to a DWDM system.

An optical line board integrates the WSS, transmit/receive OA, OSC, and XFIU units. It can be regarded as a collection of traditional optical-layer boards. One optical line board can implement grooming of one line direction in an ROADM node.

Spectrum analyzer boards can not only support detecting the insertion loss between boards in the subrack and the optical backplane, but also can support centralized monitoring of optical signals without impacting the signal performance.

A system control and communication board interoperates with the NMS to manage boards and achieve communication between NEs. It supports NE data backup, intra-subrack configuration management, and alarm output.
