Connectors, adapters, attenuators

Fiber optic connector (optical connector) is an element of a FOCL network used to terminate optical fibers and optical cables for their subsequent connection to passive or active elements of FOCL fiber optic communication lines. OPTOKON manufactures more than 20 types of optical connectors. This section presents the most used and basic types of optical connectors: FC, SC connector, ST, LC, MU type, as well as Quick-Cure (fast connector). The basis of an optical connector is a ferrule (core) with a channel in the middle. The ferrule is made of high quality ceramic, which allows the fiber to be preserved for multiple uses. The diameter of the channel depends on the type of optical fiber: single-mode fiber or multimode fiber. For single-mode it is 125 - 127 µm, for multimode it is 127 - 130 µm. For most types of optical connectors, the core diameter is 2.5 mm, but in modern optical connectors such as LS, MU, use a diameter of 1.25 mm. Optical fiber is tightly fixed in the connector by adhesive method, and the end of the core is polished to the required polish quality. Bare fiber adapter is used for quick mechanical connection to optical single-mode or multimode fiber with primary coating of 0.25 mm diameter. Basically optical sockets of this type are used for temporary connection of optical cable to the network. And its main application is to restore the operability of the optical line for some time and input control of optical fiber. They are reusable fiber optic connectors and are used for repair or optical measurements (tests). A bare fiber adapter consists of a special device that clamps the fiber and holds it in a 0.9 mm diameter buffer coating and a specific type of optical connector. Such adapters are used for the most common types of FC, SC connectors. FAST connectors - traditionally used in the field for quick installation of optical connector of the required type on optical cable or optical fiber. There are several technologies of fast connectors - gel connectors (Optokon QuickCure), welded connectors (Optokon SpliceOnConnector) or mechanical connectors.
