Fiber-optic connectors: according to ITU, are passive components used to stably
but not permanently connect two or more optical fibers. They are indispensable to
a fiber-optic communications system in the sense that it allows add/drop
connections between optical channels.
Many types of fiber-optic connectors are available, such as:
FC: round fiber-optic connector with screw thread
ST: round plug-in fiber-optic connector
