Connecter Color-coded Pigtail

With the widespread application and rapid development of optical transmission equipment, the use of optical patch cords (ODF) and pigtails in the communication room has also increased dramatically. However, many units do not pay much attention to this aspect of management. The gathering of hundreds of pigtails from all directions to a certain location is a big test for the cleanliness and beauty of the computer room and the safety of business transmission. It can often be seen that after many pigtail jumper operations, the originally neat pigtails and optical jumper racks often become messy, difficult to sort out, and difficult to remove when they are not used. Not only has it seriously affected the appearance of the computer room, but also brought inconvenience to future operations, and also brought a greater threat to the security of the ongoing business.
The ODF rack should be distributed:
It is often seen in the equipment room that certain sections of the trunking are covered with pigtails, overlapping each other, while the pigtails in other trunks are very few. The occurrence of this situation is not conducive to the safety of the transmission business, but also It is detrimental to the beautiful environment of the computer room and causes a waste of resources. The main reason for this phenomenon is that the layout of the ODF rack in the computer room is not reasonable enough, and a large number of equipment that needs to use optical fibers are concentrated in a certain direction of the ODF rack. In order to avoid such phenomena, consideration should be given to the design and construction of the computer room. The ODF frame can be set in the center of the computer room to facilitate the pigtail to reach any position in the computer room, and the distribution of optical transmission equipment in the computer room should be considered.
Set the ODF jumper:
For the failure to make a reasonable layout during construction and design, or for some reason, there is indeed a large number of equipment that has a huge demand for optical fiber resources in a certain direction of the ODF rack, and the sub-ODF rack should be installed appropriately according to the situation. Replace a large number of optical jumpers in the trunking with optical cables. The sub-ODF rack is installed at the near device end. When performing fiber jumper operations between the equipment in the cabinet and the ODF rack, first jump to the corresponding sub-ODF rack and then jump from the sub-ODF rack to the equipment in the cabinet. But it should be noted that this kind of design will have a certain degree of optical attenuation, and the loss of experience value increase is below 1dB.
Optical fiber routing channel:
Due to the limited space resources of many computer rooms, generally only one cabling channel is set in the computer room, and the pigtails are routed together with the electrical signal cables. Because the pigtail is afraid of pressure and lacks a protective layer, if it is not protected by a sleeve, the pigtail is easily damaged and safe transmission is threatened. If the pigtail is protected by a pipe, the pigtail will not be threaded a few times, and the cable duct will be full. The arrival of the trunking is a waste of resources and is not conducive to the beauty of the computer room. If you can use special fiber optic cable routing channels. It can save the pigtail through the pipe protection, which saves resources and is conducive to the beautiful environment of the computer room.
Selection of ODF frame:
(1) There must be sufficient space for storing redundant pigtails.
(2) The flange interface of the ODF frame should be convenient for maintenance. If there is a problem with a flange interface, pull out a certain row where it is located, replace it and use it. (The commonly used ODF frame has 12 flanges as a unit, repairing one core will affect the other 11 cores).
