The Fiber Patch Panel is a wiring connection device between an optical cable and an optical communication device or between an optical communication device. The fiber optic patch panel is used for the end-to-end and distribution of the backbone cable in the optical fiber communication system, which can easily realize the connection, distribution and dispatching of the optical fiber line. With the increasing degree of network integration, there have been set ODF, DDF, power distribution unit in one of the number of light mixed patch panels for fiber to the district, fiber to the building, remote module and wireless base station in the small and medium-sized Line system.
There are three types of fiber patch panels. Unit-type fiber patch panel is installed in a rack a number of units, each unit is a separate fiber patch panel. This patch panel not only retains the original characteristics of small and medium-sized optical fiber patch panel, but also through the structure of the deformation of the rack, providing space utilization, is a large-capacity optical fiber distribution frame early common structure. But because of its inherent limitations in the provision of space, in the operation and use of a certain inconvenience.
The drawer's fiber patch panel also divides a rack into multiple units, each consisting of one or two drawers. When the welding and transfer line, pull out the corresponding drawer to operate outside the frame, which has a larger operating space, so that each unit does not affect each other. The drawer is provided with a locking device in both pull-out and push-in conditions to ensure safe and reliable operation and use of devices within the unit.
Modular structure is the fiber optic patch panel is divided into a variety of functional modules, fiber optic cable splicing, transfer lines, cable storage and other functional operations, respectively, in the module to complete, these modules can be combined according to the need to install a common rack Inside. This structure provides maximum flexibility to better meet the needs of the communications network.
The selection of fiber optic patch panel is an important and complicated work, all localities should be based on the specific circumstances of the local, taking full account of various factors, in a serious understanding, repeated comparison on the basis of a best to meet the current needs And the future development of fiber optic patch panels.
