ODF, DDF and power distribution units have been integrated into optical fiber distribution frame. These optical distribution frame is compatible with fiber-to cell, fiber-to building, remote modules, and wireless base stations. A small or medium-sized distribution system is capable of facilitating the scheduling, connection and distribution of optical fiber lines.

The optical fiber distribution frame plays an essential role in the current communication network.

The optical distribution frame is used to terminate and distribute the central office trunk optical cables in the process for communication system construction and network connectivity.

It can be used between optical communication equipment and optical cables. Wiring between devices.

The odf optical distribution frame is flexible enough to connect equipment and equipment, equipment, and optical cables. It also serves the purpose of scheduling and allocating fiber core resources, as well as fixing and protecting optical cable.

Mechanical moving parts must be easy to install, maintain, and rotate. The door’s opening angle should not exceed 110deg and the gap between the two should not exceed 3mm.

The bending radius of an incoming optical cable should not exceed 15 times its diameter when it enters the rack.

The structure must be strong, the assembly must be consistent, interchangeable and free from loose fasteners. Round edges should be used for exposed or manipulated areas.

Protective cover and gasket must be placed when the optical fiber of an optical cable passes through the hole in the plate. The radius of curvature must not be smaller than 30mm, regardless of where the fiber core or pigtail is bent.

The coating layer must have a smooth, uniform surface and color. There should also be no exposed bottom.

Text, graphics, symbols, and signs for the structural device must be clear, precise, and complete.

There are three types of optical fiber distribution frames: open, semi-closed, and closed. The odf optical distribution frame can be broken down into three parts depending on the use scenario: the optical odf for the cell fiber box distribution, the distribution frames of the wireless base stations distribution and the transmission area. Distribution frame, mixed distribution frames and other types.

The odf optical distribution frame structure allows it to be broken down into

Closed optical fiber distribution frame generally refers to ODF’s front, north, and side. Panels or doors are used to install ODF with doors or panels.

Semi-enclosed fiber optical distribution frame. This means that the front or rear part of the frame is exposed and the sides are generally closed.

The front is left completely exposed in an open fiber distribution frame.

It can be subdivided according to the rack operation mode into:

Fully front-operated optical fiberdistribution frame. This generally refers to ODF’s front-side operation.

Double-sided operation fiber distribution frames refer to operation from either the front or the back of ODF.

Depending on the functional composition of your rack, you can divide it into:

Generally, an ordinary optical fiber distribution frame refers to the structure of an individual rack.

A combined fiber optic distribution frame is a combination of two or more racks and wiring channels.

It is distinguished primarily by the diameter of the cores that carry the optical cables. The optical fiber distribution frame can be divided according to how many cores each one carries. This is typically 144 cores or 288 cores.

The rack height can be divided into three groups: 2600mm, 2200mm, and 2000mm. Its width should be an integer multiple 120mm. Its depth should be 300mm, 600mm, or 450mm.

The frame dimensions must not be deviated by more than +-2mm. The verticality tolerance between the outer surface and the bottom reference plane should not exceed 3mm.

Optical cable is an essential part of modern communication. This has been made possible by the construction of large-scale all-optical networks in the early stages. Traditional DDF optical distribution frame has also grown in importance to connect optical cable and equipment.

The shortcomings of using traditional optical odf extensively are slowly being exposed with the advancements in traditional telecom operations services like wireless networking, home broadband and group private lines as well as emerging 5G service offerings.

Access layer optical cables and aggregation layers optical cables are often connected to the appropriate communication equipment rooms. This increases optical odf ends demand and optical cable carrying capacity in computer rooms at all levels. Additionally, the number of odf optical distribution frame optical jumpers connecting to corresponding equipment is increasing. optical odf racks in computer rooms have the issues of limited space, low capacity and a single function. This eventually leads to tight spaces in transmission and data equipment rooms and congestion of fiber jumper channels.

Multi-device connectivity and multi-service concurrency are the norm in 5G network construction. The existing equipment room space is no longer sufficient to accommodate the network construction requirements of multiple types of equipment and ODF racks.

Comparable to previous mobile communication technology upgrades the O&M era will see changes in network standards, business operations, and a complete upgrade of network O&M techniques. Traditional optical odf only perform the basic tasks of terminating optical cable and connecting equipment.

The number of users connected to the network and the scope of operation has led to a multiplication of optical fibers.

Mixed connection of data devices at different network level on the odf optical distribution frame side leads to unclear optical path levels. This includes the backbone fibers in the cell, important group fibers and surrounding base stations fibers. Cable management can be very difficult. Side faults can make it difficult to identify the faulty cables or ports the first time. This puts a lot of pressure on the network operations and maintenance.

The new era of operation and maintenance has seen unprecedented network integration, with the content of services and terminals continuing to diversify. There are many new applications that emerge daily, and this requires a higher level of resource accuracy in the back-end network.

Traditional ODF doesn’t divide the passive integrated wiring and active equipment areas, lacks unified planning and labeling, and the locations can be quite scattered.

The principle of proximity is used for the connection and setting of the original ODF. Sometimes, the actual construction and maintenance of engineering can be hampered by inaccurate resources on site, which could pose hidden risks to the reliability and security of the network.

It is essential to plan the layout of the optical fiber distribution frames, optical cables, and pigtails within the equipment area in order to create a space-efficient layout. This will solve the three main problems of equipment room space, operation difficulty, resource accuracy, and resource accuracy. The following requirements must be met in order to divide the application scenarios within a general communication area.

(1) Before you use the optical fiber distribution frame, it is important to consider the area division of power supply, equipment, and MODF rack areas, clarify the scene classification, and realize the central and separate placements of the MODF Rack, in order to efficiently move the equipment space. This will lay the foundation for unified deployment, and utilization.

(2) It is important to take into account the environment and previous layouts when installing the optical fiber distribution frames. The columns are arranged in the same column which makes it easy to place fiber jumpers and saves resources.

(3) The optical fiber distribution frame should not be placed too close to the side of optical cable that enters the equipment room. This will allow for the use of old optical cables and pigtail channels, as well as reduce construction cost and investment.

Equipments (OLTs), which have a lot of user accesses such as FTTx access networks or cell resident networks, should reserve a certain amount of pigtails to meet future user development. This will allow for optimization and expansion of the network in later stages.

Connect the standard fiber patch using the dotted line (SiR2) and adjust the optical powers so that ODB is achieved (use the set key 0). Connect the fiber to be tested according to the solid line. The measured optical power value corresponds to the insertion loss value at the R1 end. The corresponding insertion value for the other end can also be measured if the fiber jumper direction is reversed.
