The Optical Fiber Distribution Box is suitable for the connection between the optical cable and the optical communication equipment. Through the adapter in the power distribution box, the optical signal is led out using an optical jumper to achieve the optical wiring function. It is suitable for the protective connection of optical cables and leads, as well as the fiber termination points in optical access networks. It is suitable for the protective connection of optical cables and leads, as well as the fiber termination points in optical access networks. From these three points you can get a deeper understanding of fiber distribution boxes.
Classification of fiber distribution equipment. As one of the key equipments of optical access network technology, optical fiber distribution equipment is mainly divided into indoor distribution equipment and outdoor distribution equipment. Among them, indoor distribution frames include rack type (hybrid distribution frame, optical distribution frame), cabinet type (hybrid distribution frame, optical distribution frame) and wall-mounted (optical distribution box, integrated distribution box) . Outdoor power distribution equipment includes distribution boxes, fiber optic junction boxes, and fiber optic junction boxes. These power distribution devices are mainly composed of power distribution units, fusion units, fixed and peeling protection units for optical cables, storage units and connection equipment. Integrated distribution products include corresponding digital distribution modules and audio distribution modules.
Fiber optic fixed connector technology. The requirements for fixed connections are low loss, small back-reflected light, simple operation and stable performance. Methods of making fixed joints include welding, V-grooves, capillaries, and sleeves. The most commonly used method in practical applications is fusion. In the future, there are three main development directions:
- V-groove and capillary structure are used to realize the fixed connection between ribbon fiber and light wave array, light and passive device array.
- Multi-core. In order to match the application of ribbon cables, it is necessary to develop multi-core fixed connectors;
- Improve accuracy, develop better matching fluids, and expand the application range of V-grooves, capillary tubes, and sleeve joints.
Application range of optical fiber distribution box. The introduction of optical cables, fixing and stripping protection, fusion and protection of optical fibers, storage of pigtails, storage and management of jumpers, fixed connection and cross-connection of optical fibers, etc. At the same time, optical splitters and wavelength division multiplexing can be installed according to customer requirements Value-added modules such as appliances.
