What are the classifications of optical fiber distribution frames

<p>The <a href="https://www.tel-bridge.com/fiber-optic-distribution-frame" rel="noopener noreferrer" target="_blank">optical distribution frame</a> is connected to the optical fiber connectors. In the integrated wiring, the optical fiber distribution frame will appear after the optical fiber appears, and the optical fiber generally appears in the vertical subsystem, then the problem is here, what are the optical fiber distribution frames Classification? Follow us, we will tell you some classifications of optical fiber distribution frames.</p><p><br></p><p>Unitary</p><p>The unit type optical fiber distribution frame is to install multiple units on a rack, and each unit is an independent optical fiber distribution frame. This type of distribution frame 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 frame. It is a common structure in the early days of large-capacity optical fiber distribution frames. However, due to its inherent limitations in space provision, there are certain inconveniences in operation and use.</p><p><br></p><p>Drawer type</p><p>The drawer type optical distribution frame also divides a rack into multiple units, and each unit is composed of one to two drawers. When welding and adjusting the wires, pull out the corresponding drawer to operate outside the shelf, so that there is a larger operating space, so that each unit does not affect each other.</p><p>The drawer is equipped with a locking device in both the pull-out and the push-in state, which can ensure the stability and accuracy of operation and the safety and reliability of the connecting devices in the unit.</p><p>Although this kind of optical fiber distribution frame cleverly provides a larger space for the operation of the optical cable terminal, it still cannot provide the greatest convenience in the storage and placement of the optical connection line, like the unit type. This kind of rack is currently the most common form.</p><p><br></p><p>Modular</p><p>The modular structure divides the optical fiber distribution frame into a variety of functional modules. The fusion of optical cables, wiring, connection line storage and other functional operations are completed in each module. These modules can be combined and installed in a common rack as required. Inside. This structure can provide maximum flexibility and better meet the needs of communication networks.</p><p>The introduced modular high-capacity optical fiber distribution rack uses unique structures such as panels and drawers to make the operation of optical fiber splicing and wiring more convenient; in addition, the use of vertical wiring troughs and intermediate distribution racks effectively solves the problem of pigtail distribution. Putting and storage problems. Therefore, it is the most popular kind of large-capacity optical fiber distribution frame, but its cost is relatively high.</p>
