What Is an Optical Cable Adaptor?

Optical fiber connectors are the most used optical passive devices in optical fiber communication systems. Most optical fiber connectors are composed of three parts: two fiber connectors and a coupler. Two fiber optic connectors fit into the two fiber ends; the coupler acts as an alignment sleeve. In addition, couplers are often equipped with metal or non-metal flanges to facilitate the installation and fixation of connectors.
