Fiber distribution frame classification

What are the classifications of optical fiber distribution frames? Fiber optic distribution frames are connected to fiber optic connectors. In integrated cabling, fiber distribution frames appear after the appearance of optical fibers, and optical fibers generally appear in vertical subsystems. So the question is, what are the fiber distribution frames? Classification? What are the functions of optical fiber distribution frame? How to calculate the fiber distribution frame?

Fiber distribution frame classification

1. What are the classifications of optical fiber distribution frames?

The unitized 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 rack. It is a common structure of early large-capacity fiber optic distribution frames. However, due to the limitations of its inherent space, there are certain inconveniences in operation and use.

The pull-out optical fiber distribution frame also divides a rack into multiple units, and each unit consists of one or two drawers. When welding and adjusting wires, pull out the corresponding drawer to operate outside the frame, so that the operation space is large, so that each unit does not affect each other.

The pull-out type is equipped with locking devices in both pull-out and push-in states to ensure smooth, accurate, safe and reliable operation of the connecting devices in the unit.

Although this kind of optical fiber distribution frame cleverly provides a large space for the operation of the optical cable terminal, it still cannot provide the greatest convenience in the storage and arrangement of optical connection lines, just like the unit type. This rack is by far the most common form.

Modular

The modular structure is to divide the optical distribution frame into various functional modules. Functional operations such as connection of optical cables, wiring, and storage of connecting wires are all completed in each module. The modules can be combined and installed in a common rack as required. in. This structure can provide maximum flexibility and better meet the needs of the communication network.

Launched a modular large-capacity optical fiber distribution frame, which adopts unique structures such as panels and drawers, making the operation of optical fiber fusion and wiring more convenient; in addition, the use of vertical wiring troughs and intermediate distribution frames effectively solves the problem of pigtail wiring. Placement and storage issues. Therefore, it is the most popular type of large-capacity fiber distribution frame, but its cost is relatively high.

2. What are the functions of optical fiber distribution frames?

The optical fiber distribution frame plays an important role in the safe operation and flexible use of the optical fiber communication network, which is embodied in the following four aspects:

After the optical fiber jumper enters the rack, the optical fiber distribution frame can fix the optical fiber jumper on the rack, and can also mechanically fix the outer sheath and strengthening core, so as to protect the optical fiber jumper from external mechanical damage.

The optical fiber distribution frame adopts a box structure, which can save space and optimize cable management.

The high-density pre-termination system used in the optical distribution frame can enhance the performance of the network, making the network reliable and scalable.

Optical fiber distribution frames can conveniently and quickly perform high-density interconnection and cross-deployment in data centers, simplify wiring deployment, increase wiring density, effectively reduce wiring faults, and achieve flexible wiring.
