The TNG2WSMD09 board is a 9-port wavelength selective multiplexer/demultiplexer for the Super C band and supports optical power adjustment and online optical power detection.

G.652-specific DCMs are designed for standard single-mode fibers and generally cannot properly compensate dispersion in G.655 (Leaf) fibers, which have different dispersion characteristics. Using G.652 DCMs for G.655 fiber compensation is therefore incorrect.

The electrical-layer structure of OTN frames follows the path: OTUk → ODUk → OPUk → Client. OTUk is the outer frame layer that carries ODUk (Optical Data Unit), which in turn contains OPUk (Optical Payload Unit). The OPUk holds the client signal payload. This hierarchical encapsulation supports transparent transport of client signals over optical networks. Understanding this sequence is essential for managing signal mapping and monitoring in OTN networks as outlined in HCIP-Transmission documentation.

The statement that the OA gain can be reduced when expanding 100G channels in a 10G system to meet incident optical power requirements is false. In fact, the single wavelength incident optical power of a 100G system is higher than that of a 10G system, and gain adjustment needs to ensure the 100G channels meet their power requirements without degradation. Reducing OA gain indiscriminately could cause insufficient amplification for 100G signals, impairing performance. HCIP-Transmission specifies careful power management and gain setting to balance multi-rate systems during hybrid transmission expansion.
