When installing any fiber system, we must consider low-loss method to connect fiber or cable with each other, to achieve the connection of the optical link. The combination of fiber optic link can be divided into two types: permanent and active. Permanent connection is achieved by splicing or fixed connectors; splicing connections usually achieved with connectors. Here I'd like to share some information of fiber optic connectors.
Generally, one connection needs one adapter and two connectors which are often used to join optical fibers where a connect/disconnect capability is required. Since fiber optic connectors have such merits as lower loss, lower cost, easier to terminate and to quicker connection and disconnection than splicing, they are widely applied in telephone company central offices and in outside plant applications to connect equipment and cables, or to cross-connect cables. Many types of optical connector have been developed at different times, and for different purposes.
With the rapid development of optical fiber telecommunication, many different types of fiber connectors are available, they share similar design characteristics. A fiber connector is mainly composed of three parts: the ferrule, the connector body, and the coupling mechanism. And the common types are FC, LC ESCON, MTC, SC, MPO/MTP, MU, ST, MT-RJ, etc. They are unique. Fiber cables transmit pulses of light instead of electrical signals, so the terminations must be much more precise. Instead of merely allowing pins to make metal-to-metal contact, fiber optic connectors must align microscopic glass fibers perfectly in order to allow for communication.
