Ftth Box communication network has become the cornerstone of today's information dissemination world. With the further development of the network and the growing demand for communication bandwidth, users are using fiber in the last ten kilometers and the last mile of the entire communications network. FTTH mainly uses PON network technology, which requires a large number of low-cost optical splitter and other optical passive devices. The optical splitter is part of the FTTH network. With the promotion of FTTH, the market demand will be even greater. From the perspective of optical device development can be seen, fiber splitter has become a high-performance, low-cost optical splitter large-scale preparation of the mainstream technology. Through the production and optical fiber array package combination optical splitter chip, completed the optical splitter preparation, is the use of fiber optic PLC splitter. It is characterized by small size, low cost, good brightness of the spectroscope. But at the same time the technical threshold is relatively high, especially the mass production of large optical splitter production. In the international arena, ODF patch panel has been widely used in small-scale, high-performance optical device manufacturing and production, especially optical splitter chip. Optical engineers often use the ODF patch panel to test fiber in fiber optic cables. When the fiber is separated and tested separately, the fiber optic cable problem can be located within a single fiber. The wiring board can easily organize the fibers. In addition, working with the fibers in the tray of the fiber optic patch panel protects the fibers from any objects that may damage them in the environment. The fiber optic cable needs to be separated at one end to access the individual fibers. Separate the fibers into different ports, each with a fiber adapter. You can then use these adapters to insert individual fibers into other devices. The adapter on the ODF patch panel can have a variety of different shapes. In most panels, all adapters are of the same type, but if you are using multiple types of fiber connectors in your network, you may need to use a hybrid adapter to get the patch panel. These types of adapters can be used to connect different types of connectors on fiber optic cables. GreenTel provides various shapes Inline Closure. All the closures we offered are with a great sealing performance. High quality ABS material also ensures the durability whether the closure is in air, in pipeline or buried underground.
