Explanation
100G optical transport systems are built around three functional layers: the WDM line-side interface (A) handles wavelength multiplexing on the optical network, OTN processing (B) provides framing, forward error correction (FEC), and signal monitoring/management, and the client-side interface (C) connects the system to routers, switches, or other customer equipment - together these three cover the complete signal path from client to network and back.
Dispersion Compensation (D) is excluded because modern 100G coherent systems handle chromatic dispersion electronically inside the coherent DSP/ASIC, eliminating the need for external dispersion compensation modules (DCMs) as a standalone architectural component - it's absorbed into the processing layer, not a separate key technology.
Memory tip: Think "WOC" - WDM side → OTN core → Client side - the three interfaces that define a 100G system from edge to edge. If you see "Dispersion Compensation" as an option, remember that 100G coherent technology made external DCMs largely obsolete.
