Fiber optic adapters are used in fiber optic connection, the typical use is to provide a cable to cable fiber connection. ST fiber optic adapters are all threaded type, single mode ones are with zirconia sleeve and multimode ones are with bronze sleeve.
Fiber optic adapter is to achieve the same or different optical fiber connectors docking in optical links，make the light path connected under the small loss.It is to put the fiber of two surface precision docking, so that the optical output of light energy to the maximum coupling in the receiving optical fiber,and since it entered the optical link to minimize the effects on the system.Widely used in optical fiber distribution frame (ODF), fiber optic communications equipment, instruments, etc., superior performance,stable and reliable.
