LC versus SCIdentify the optical connector family; verify fiber and end-face polish independently.ST, SC and LC fiber formsIdentify exterior form only; no optical compatibility result.opticalCON DUO versus QUADDoes the fiber system specify opticalCON DUO or QUAD, and how many optical channels are documented? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.SMPTE 304M camera connector versus opticalCON DUO SMPTEDoes the camera link require the SMPTE 304M connector family or the distinct opticalCON DUO SMPTE system? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.FC vs ST fiber connectorsDistinguish the documented FC key/adapter arrangements from the ST bayonet example. A hybrid sleeve does not settle polish, fiber type or optical loss.
