After splitting wiring box can store coiled fiber and fiber cable splicing leads households to achieve direct function of the cable to meet the needs of traditional transmission network project ODF Optical Distribution Frame ODF (Optical Distribution Frame) fiber optic patch panel is designed for fiber communications room designed fiber optic wiring devices, with fixed cable and cable termination protection function, transfer line function generates background light communication cable used in the construction of the past typically a few tens of core to core optical fiber distribution frame capacity generally 100 core less, these fibers exhibit a small patch pigtail more storage capacity, the deployment inconvenient connecting operation, less functionality, and simple construction shortcomings. Now relay transmission in optical communication has a long trunk and local networks widely used fiber optic technology has become the development direction of the access network. around in new fiber optic network construction, both try to use large core fiber optic cable, so that the fiber distribution frame capacity, function and structure made more high demand. 2 main functions can ODF pigtail cable core and protect function. ODF [1] can be assembled into a single optical fiber distribution frame, but also with digital distribution unit, the audio wiring unit with mounted in a cabinet / rack constituting integrated distribution frame. The device configuration flexibility, simple installation, easy to maintain, easy to manage, it is the fiber-optic communications cable network terminal, or a relay point to achieve emission fiber, fiber optic cable splicing and jump access to essential equipment. 3 Applications cabling systems, patch panels or equipment for horizontal wiring termination devices, and the focal point of interaction with termination. sturdy and easy to install design reduces installation and Operating expenses, facilitating greater positive identification space port identification, easy to manage, in line with the 19 "rack mounting standard. It is an optical transmission system is an important equipment, mainly for fiber splicing cable ends, an optical connector is installed, then adjust the optical path, the extra cable pigtail storage and protection, it is for the safe operation of optical fiber communication network and flexible use plays an important role. 4 basic types of fiber optic patch panels can be divided according to the different structure of the wall-mounted and rack type. wall-mounted fiber optic patch panels can be fixed directly on the wall, usually box structure for the number of cable and fiber counts are small places. rack ODF can be installed directly in a standard rack , and suitable for large-scale optical network rack patch panel is divided into two types, one is a fixed configuration of patch panels, fiber optic coupler is fixed directly to the chassis; Another modular design , the user can select the number and size of the cable corresponding module, to facilitate the restructuring and expansion of the network. 5 Features standard 19-inch width of the unit, either rack mount patch panels can also do wall mounting. Sophisticated technology structural parts with thick galvanized cold-rolled steel and surface passivation coating process, fiber distribution panel with plastic material doped with fire-retardant materials, light and flexible, yet durable. Large-diameter coiled ring design makes jump fiber pigtails and radius of curvature of each of these properties are held in more than 40mm. Either alone or assembled into an optical fiber distribution frame, but also with digital distribution unit, with audio wiring unit housed in a cabinet / rack and constructing an integrated distribution frame. Having cable entry, fixed and protection, cable termination and pigtail splice function, transfer function and jump fiber line storage, and pigtail cable core storage and protection functions. Drawer structure wiring box drawer-type structure, the operation may be withdrawn after completion back. 6 Common Specifications ODF unit 2.24 1.12 3.36 ODF ODF unit unit unit 5.72 4.48 ODF ODF ODF fiber distribution frame unit are galvanized and cold-rolled steel surface coating technology, fiber distribution panel using doping flame - The spray shrink material, light and flexible, and durable, with cable entry, fixed and protection, the cable terminal and pigtail splice feature, users can according to the actual needs of the number of matching the number of units or flange Specifications: Fiber ODF distribution wire rack 24 core / 48-core / 72 cores / 96 cores / 144 core is actually the ODF should be classified into the terminal box a class, rather than to patch a classification category. Security unit Security unit is inserted in the main distribution frame (MDF) terminal block for security personnel and equipment to prevent overvoltage, overcurrent damage the device. In the field of communications security unit mounted on the patch panel and shoulder protect communications equipment from over-voltage, over-current damage to the task. Security unit is inserted in the main distribution frame (MDF) terminal block for security personnel and equipment to prevent overvoltage, overcurrent damage devices. The so-called over-voltage, over-current, is to point out now foreign voltage and current devices on the device itself exceeds the normal operating voltage and current. Security unit, with the over-voltage, over-current protection devices and development progress. Currently, according to the device and product mix mainly: gas discharge tube plus PTC, PTC and other semiconductor discharge plus two types of security units. 1, the gas discharge tube plus PTC security unit works: When external over-voltage, gas discharge tube discharge current is directed into an outside line, if the duration is longer, the heat discharge sustaining discharge issued by hot melt melting block so that the outside of the direct conduction, short-circuit fail-safe, while the output alarm signal; when the line suffered when the current invasion, PTC resistance is rising rapidly, so that the line is similar to the open state, over-current phenomenon under control, after the overcurrent disappear, PTC automatic recovery; 2, semiconductor discharge plus PTC security unit model is ionized gas tube discharge, after discharge temperature is high, it may affect the life of the main distribution frame; at the same time the presence of the gas discharge tube and failure due to chronic leakage phenomenon, and the ground outside after failure presents an open state, in this case, reduce the reliability of protective security unit, can not even play its due protection. Semiconductor discharge security unit in addition to a gas discharge tube security unit basic functions, there are the following characteristics: semiconductor discharge due to low temperature, are unlikely to cause a fire; chronic leakage phenomenon does not exist, the reliability of protective security unit; semiconductors discharge voltage surge on the reaction rate can be lower than 1ns, fast response.
