Fiber Optic Rack And Cabinet

               The function of fiber-optic cabinet The fiber distribution frame is an important accessory equipment in optical transmission system, it is mainly used in optical fiber fusion, optical connector installation, optical path adjustment, redundant tail fiber storage and optical cable protection, it is important for the safe operation and flexible use of optical fiber communication network. Over the past more than 10 years, optical communications in the construction of the use of fiber optic cable is usually a few cores to dozens of cores, fiber-optic wiring rack capacity is generally under 100 cores, these fiber-optic wiring racks are more and more performance of the tail fiber storage capacity is small, the deployment of connection inconvenience, less function, simple structure Now optical communication has been widely used in long-distance trunk line and local network relay transmission, and the optical fiber has become the development direction of access network. All over the new optical fiber network construction, as far as possible to choose the large core number of optical cable, so that the fiber distribution rack capacity, function and structure of the higher requirements.

              Fiber-optic cabinet structure selection of fiber-optic wiring frame structure is divided into 3 types, that is, wall-mounted, cabinet-type and rack-type. Wall-hung type generally for the box structure, applicable to the number of optical cables and fiber core number of the Bureau is smaller; cabinet type is closed structure, core capacity is relatively fixed, the appearance is more beautiful; rack-type general is the use of modular design, the user can be based on the number of optical cables and specifications to choose the corresponding module, flexible assembly in the rack, it is a future-oriented structure, you can provide convenient conditions for the development of fiber-optic wiring rack. Optical fiber wiring frame should be used as far as possible to choose aluminum frame, its structure is firmer, the appearance is also beautiful. The size of the frame should be similar to the standard frame of the current transmission equipment to facilitate the arrangement of the machine room. Surface treatment process and color should also be similar to other equipment in the computer room to maintain the overall beauty of the room.Fiber Optic Rack And Cabinet

               Functional types of fiber-optic cabinets: The fiber-optic wiring frame as the terminal equipment of optical cable line should have 4 basic functions. After the ① fixed function cable enters the frame, the outer sheath and the reinforcing core should be mechanically fixed, the ground protection parts are installed, the end head protection is disposed, and the optical fiber is grouped and protected. After the fiber and the cable are fused, the extra fiber is coiled and stored, and the weld joint is protected by ②. The ③ leveling function plugs the connectors on the tail cable into the adapter and realizes the optical alignment with the optical connector on the other side of the adapter. Adapters and connectors should be flexible and unplugged, and the optical path can be freely provisioned and tested. The ④ storage function provides storage for a wide range of intersecting optical connections between racks, enabling them to be neatly placed in a regular manner. The wiring frame should have proper space and way so that this part of the optical connection line clear, easy to adjust, and can meet the minimum bending radius requirements.Fiber Optic Rack And Cabinet

               With the development of optical fiber network, the existing functions of fiber optic wiring rack can not meet many new requirements. Some manufacturers put some optical fiber network components, such as optical splitter, wavelength division multiplexer and optical switches, etc. directly into the fiber-optic wiring rack. In this way, both the components are conveniently applied to the network, and the fiber-optic wiring rack is added the function and flexibility.Fiber Optic Rack And Cabinet
