The fiber optic connectors provide mechanical connection between two individual optical fibers. If used in a network to connect to optical fibers, fiber optic connectors provide connectivity within acceptable limits of loss budget. Since fiber optic connectors are easy to use and handle, they often replaces the time-taking and expensive fusion splicing methods. Fiber optic connectors are preferred, if the link loss budget can accommodate optical loss due to such mechanical connections.
If used in optical transmitter, a fiber optic connector aligns the optical fiber with light emitters in transmitters, In receivers, a connector aligns the fiber with the photo-detectors.
Major function of a fiber optic connector is to provide connectivity between two optical points. They combine two physically separated optical media by acting as an intermediator for the optical signal to pass from one medium to another medium.
Many connector types are available in the market and it is really confusing and hard to remember the advantages of each type of connectors. It is interesting and easy to remember connector types if we go through their development history. For example, the LC connector developed by Lucent.
With the development of various connector styles, each one has its own advantages, disadvantages, and capabilities. All fiber optic connectors have four basic components, which are the ferrule, connector body, cable, and coupling device.
