As the number of users, fiber optic cabling has become increasingly complicated, how to effectively use data transmission and engine room space, rational management of the engine room cable becomes increasingly important. Fiber Distribution Box (Optical Fiber Distribution Box, referred ODB) optical transmission system is an important device, generally placed in the optical communication equipment room or rack, and for managing the fiber optic terminal wiring implement functions. Application of a fiber distribution box installer to provide richer functionality and flexibility of the wiring.
Fiber enclosures are usually rack, rack, wall-mounted. Usually 19-inch rack for rack mounting, according to the number of connections required, they have one or more rack unit (RU) height configuration, such as 1U, 2U and the like, or 4U. That is U Unit, generally refers to the height of network devices. Specifically, 1U equal to 44.45mm (1.75 inch) height of the rack, 2U mounting height is 2 x 44.45 = 88.88, or 3.5 inches. 3U height is 3 x 44.45 = 133.35mm, that is 5.25 inches. Standard size was developed by the Electronic Industries Association (EIA) of. The main difference IU / 2U / 4U fiber wiring box that can support different heights and fiber count.
Rack fiber distribution box is divided into different installation methods: drawer slide out and removable. A side-opening and drawer can more easily use the device, but they tend to cost more. The removable housing is usually cheaper, but not so easy maneuverability. Wherein the box is a drawer type optical fiber distribution type current application. Drawer Fiber Enclosure What are the characteristics of it?
Split tray design, convenient operation
drawer tray design is the use of split, the cartridge module can independently mounted sliding when superimposed. With separate pull mounting portion clinch locking means to prevent slipping. And a sliding tray having a locking function, can be withdrawn directly drawer slide to use, and can be withdrawn after the wiring work in lock, is very convenient.
Compact, high-density wiring, space saving
compact design, can accommodate a higher fiber density and the number of ports, the wiring density so as to enhance, maximize space-saving rack. HYC design of the chassis, a single cartridge 24 with a channel, 1U cartridge 6 can hold a maximum with the core 144 of the core 72 or LC connector SC connector; 2U cartridge can hold 12, the core 288 can be equipped with LC SC connector 144 or the interface of the core; 4U up with the core 576 of the core 288 SC or LC connector interface.
Rational design, efficient management cable
behind the chassis bracket with cable management, cable easy to manage, and the air in the space to ensure the circulation. Like HYC of this fiber chassis, front and rear have good wire management design, the front cartridge can be managed independently harnesses, each multilayer mounting enclosure does not interfere with superimposed easy cable management; the rear end of the casing a separate bobbin holder designed for fixing the trunk cable, a large number of redundant length of the trunk cable, to ensure that the cartridge is moved, the cable can stretch freely.
Optical Fiber Distribution Box Drawer flexible configuration, simple to install, easy to maintain, easy to manage, versatile, it can be used to jumper connectors, fiber splicing, as well as a high density optical storage MTP routing management. The main wiring area for the data center (of MDA), an intermediate distribution area (IDA) or horizontal distribution area (HDA) and the like connected to the trunk line optical fiber management, can be pre-mounted connector MPO / MTP adapter module or MPO / MTP adapter front panel, to achieve the desired interconnection between the backbone and the cross-connect cables and active devices.
HYC (English abbreviation HYC) is a national high-tech enterprises a focus on the basis of passive optical communication device development, manufacturing, sales and service in one. Main products fiber optic connector (High Density Data Center optical connector), WDM wavelength division multiplexer, PLC optical splitter, MEMS optical switch based passive optical devices are widely used in fiber to the home, 4G / 5G mobile communications, Internet data centers, defense and communications.
