Ensure Stable And Accurate Operation

The modular structure divides the optical fiber distribution frame into various functional modules, the welding of the optical cable, wiring adjustment, connection line storage, and other functional operations, which are completed in each module. These modules can be combined and installed in a common rack as needed. Inside. This structure provides maximum flexibility and better meets the needs of communication networks. The introduction of modular high-capacity fiber distribution racks makes use of unique structures such as panels and drawers to facilitate the fusion and splicing operation of optical fibers. In addition, the use of vertical wiring grooves and intermediate distribution frames effectively solves the problem of fiber pigtails. Put and store problems. Therefore, it is the most popular type of large-capacity fiber distribution frame, but its cost is relatively high.

The selection of optical fiber distribution frames is an important and complex task. All localities should fully consider various factors according to the specific conditions of the local area. Based on careful understanding and repeated comparison, one can best choose the one that best meets current needs. And future development of optical fiber distribution frames.

The unitized optical fiber distribution frame is to install a plurality of units in a rack, each unit is a separate optical fiber distribution frame. Such a patch panel not only retains the characteristics of the original small and medium-sized optical fiber distribution frame, but also provides space utilization through the structural deformation of the chassis, which is an early common structure of a large-capacity optical fiber distribution frame. However, due to its inherent limitations in space provision, there is some inconvenience in operation and use.

The drawer type optical fiber distribution frame also divides a rack into multiple units, each unit consisting of one to two drawers. When welding and adjusting the line, pull out the corresponding drawer to operate outside the frame, so that there is a larger operating space, so that each unit does not affect each other. The drawer is provided with a locking device both in the pulled-out and pushed-in state, which can guarantee the stability and accuracy of operation and the safety and reliability of the connecting device in the unit. This optical fiber distribution frame, while cleverly providing a large space for the operation of the optical cable terminal, does not provide the greatest convenience in the storage and placement of the optical connection line as in the unit type. This type of rack is currently the most common form.
