What are the advantages of optical fiber distribution frame

The popular meaning of patch panel

Distribution frame and cable management frame are a kind of equipment used to standardize network wiring. They are generally used in network installations (such as local area networks, etc.), used in conjunction with switches, and installed in cabinets.

Patch panel - the center of the network nerve

The function of the communication room and the equipment room is like the nerve center of the wiring system. The horizontal cables received from the work area are connected to the equipment ports on the patch panel in the way of mutual matching or crossover. Interconnection or cross-connection of cables is achieved through modular cables or jumpers.

The patch panel can be divided into modular patch panel (PatchPanel) and IDC type patch panel according to its operation interface. The rack can use modular IDC jumpers (commonly known as "duckbill jumpers" such as BIX-BIX, BIX-RJ45 jumpers), and cross-connect jumpers (JumperWire, CrossconnectWire) for line connection. Modular jumpers and IDC jumpers can be easily plugged and unplugged, while cross-connect jumpers require a special crimping tool (such as a BIX crimping knife) to crimp the jumper into the clip of an IDC connector.

The distribution frame can be divided into wall-mounted or rack-mounted by its installation method. Generally, the modular distribution frame is designed for rack-mounted installation, and can also be wall-mounted through accessories such as wall-mounted brackets; general IDC-type distribution frames Usually designed for wall mounting, but can also be rack mounted with some rack mount accessories or special designs.

Distribution frame is generally divided into data distribution frame and optical fiber distribution frame

3. Why use a patch panel?

1. From the design point of view

There is one requirement for integrated wiring, I don't know if you have noticed it, that is, the information point requires that the data and voice points can be interchanged when necessary, that is to say, the same voice point can be changed by the selection of jumpers without changing the wiring. Determine whether it is voice or data. In this way, the voice point and the data point are the same when wiring, and the design is very convenient, and there is no need to consider them separately.

If the cost is not an important consideration, connect all the information points to the rj45 patch panel, and then decide whether to jump to the switch or the voice patch panel through the jumper (it can be 110 or stg and other types on the voice module). Of course, this is a design that does not consider cost, and it is also a design that completely does not consider whether the terminal is voice or data. There are very few practical applications. In most cases, the difference between voice and data is considered, and there are many specific methods.

2. From the perspective of construction

There are many large-scale engineering information points. The use of jumper connection between the switching equipment and the wiring system can make construction management more convenient, and the cabinet will be very clean. After all, the jumper is much shorter. Testing is also much easier.

3. Management and maintenance

In fact, large users are very concerned about this aspect, and the patch panel can effectively improve work efficiency and reduce the time for error checking. It also provides a convenient and quick method for changing the usage mode of the terminal.

4. What are the advantages of the patch panel?

1. The traditional method of testing subscriber lines is done by manual operation. After adopting the centralized on-line method, the existing automatic test system can be used to test the subscriber lines of the remote office, so as to realize unattended or few people on duty.

2. The computer operation can be combined with the computer integrated management system to realize the automation of operation.

3. Centralized online can choose the shortest path and the nearest jumper, which only needs 2-3m, saving a lot of jumpers. The traditional method of jumper is generally more than ten meters, or even dozens of meters.

4. In case of moving the machine, changing the number and reversing the line in the project, the traditional method needs to remove a large number of jumpers, and the work is heavy. The centralized on-line method can be completed only by computer operation, which reduces the wear of the card contacts, prolongs the life of the patch panel, and reduces the occurrence of obstacles.

5.The patch panel jumper is completed in a centralized way, which avoids the confusion caused by multiple random jumpers in the traditional method, and makes the patch panel appearance beautiful and neat.
