Many types of optical connector have been developed at different times, and for different purposes. Many of them are summarized in the tables below. Modern connectors typically use a physical contact polish on the fiber and ferrule end. This is a slightly convex surface with the apex of the curve accurately centered on the fiber, so that when the connectors are mated the fiber cores come into direct contact with one another. Some manufacturers have severa.
