How to standardize the management of jumper line in integrated Cabling

For the integrated Cabling the importance of telecommunication and equipment is the convergence of data, voice and image.But for their overall design, equipment design, hardware configuration, construction maintenance and so on.
However, tend to ignore the quality between telecom and equipment inside the largest number of equipment maintenance and installation support - cable, fiber optic jumper, and ignore the problem, will give us the room management work to bring a lot of trouble.Therefore, we think it is necessary to manage the jumper correctly.

Generally speaking, reasonable jumper management can be divided into five stages: planning, preparation, wiring, testing and verification.
Jump line operation specification.
1, plan,
It is necessary to plan everything in advance.For jumper management, current and future demand planning should be done.
(1.1) change request.Various management activities, moves, additions, or changes (MAC) begin with change requests.The change request must contain all the necessary information to start the planning program.
(1.2) search records.After receiving the request form, the records should be searched to determine the circuit path used.
(1.3) correct routing.Before determining the correct jumper length, first find the best route between the connecting ports.It is usually the shortest route through horizontal and vertical cable ducts, and no other jumper or connector in the distribution frame may be obstructed or obstructed.Choose jump line, should avoid excessive slack, ensure appearance is neat.Jumping too tight will increase the tension on the connector, while excessive slack will cause trouble for jumper management and increase the management difficulty of the distribution frame.
2, preparation,
After the plan of jumping line management, it should follow the planned plan, and then should be ready to jump line management.Prepare as much as possible prior to the implementation of management operations, and study management records.Identify the location of the connection and reconnection port and the tag information for the associated port.
(2.1) first check the type of the jumper and then check the quality of the jumper.In order to ensure the quality of the jump line is correct, we have to check whether the jumper wire is damaged, in order to check if it is damaged, of course, from the first jump line to see the appearance, if conditional word, check available specialized equipment.
(2.2) then check the condition of the connection part to avoid physical damage to the connection.
(2.3) finally, it is necessary to clean the jumper joint and the connection part.
There are two ways to clean the fiber connector:
Contact cleaning method:
(1) and anhydrous alcohol wipe paper, USES the original wood pulp with special processing technology, low dust, pure texture, high water absorption, paper is exquisite, not shave perianth wiping surfaces, with low dust wiping paper with anhydrous alcohol to wipe fiber optic connectors;
(2) non-woven fabrics, do not produce fiber crumbs, strong, with no chemical impurities, soft as silk, will not cause allergic reactions, and not easy raising and dropping, as optical fiber connector or the production or test pin with a wiping cloth clean the ideal choice, in use process should cooperate with anhydrous alcohol to wipe fiber optic connectors.
(3) clean cotton swab, specially designed for internal cleaning of ceramic casing, or to be used in cleaning flange (or adapter);
(4) professional cleaner, fiber optic connectors for cleaner used for roll wipes band, outfit can scroll in the shell, without alcohol, clean every time very effectively and produce a new surface, convenient and practical.
Non-contact method:
(1) ultrasonic cleaning method, which turns the cleaning liquid into ultrasonic "liquid column" to the end face of the connector, and collects the waste liquid in the same small space and absorbs it;
(2) high-pressure blowing method. The principle is to apply the cleaning liquid on the end face of the connector, and then blow on the end face of the connector with high pressure.
(2.4) check the cleanliness of optical fiber connector.
After cleaning the fiber optic connector, you must check the end face.The general practice is to use a magnifying glass of 100, 200, or 400 times, and the image below shows the state of the fiber ends in a clean state and after being contaminated.
Jumper management, regardless of the method, for some serious pollution connector is still difficult to clean, need to cooperate with the use of cotton rod and alcohol and other cleaning fluid to deal with.
After this series of preparation work, that means that the jumper management of the wiring work can be expanded.
3, wiring
Installation of the distribution frame shall be performed according to the operating procedures.The new knot, burr, pinch and contact defects in the jumper can significantly reduce the jumper performance.To avoid such problems, the following factors should be considered:
(1) bending radius
The minimum bending radius allowed by the jumper is subject to the operating specifications of the jumper manufacturer.
The minimum bending radius of the non-shielded twisted pair (UTP) should be four times the diameter of the cable and eight times the diameter of the cable.Core 2 or 4 core level minimum bending radius of cable is greater than 25 mm, if the bending radius is less than this standard, may lead to the relative position of the wire change, leading to lower transmission performance.
(2) jumper stretch and stress.
During the wiring process, please do not overexert, or you may increase the stress on the jumper wire and connector, resulting in lower performance.
(3) binding
Jumpers do not always have to be bound. If they are bound by the firm's binding principles, do not bind them too tightly, or they will cause a twisted pair.Do not tighten the clamp too tightly, it should be free to rotate with each jumper.Use a special product and consider products that can be used repeatedly without a tool, such as a nylon adhesive tape.
4, test,
(1) after the jump line wiring to complete, but may not think whether the optical fiber link or copper link completely conform to the specifications or integrated wiring of international and national standards, it should be tested optical fiber or copper cable, only after the test standard, whether can only be judged by testing standards.
5, validation,
(1) it is worth taking some time to visualize the connection.Make sure the jumper is loose and not caught in the cabinet door.
(2) the last step is to close the worksheet associated with the change request that has been executed according to the current configuration update record.
Now the jumper is one of the important components in the integrated wiring system, especially the good management operation of the jumper wire in the data center project.It is believed that as long as the construction managers correctly and reasonably jump line management operation, it will make the whole integrated wiring become a system that is advanced, scientific, practical and reliable in the real sense.
Along with the application data center 40 g / 10 g / 100 g, the jump line installation and management becomes more and more important, the stand or fall of jump line management sometimes affect the whole channel attenuation, good management to ensure that fibre channel data transmission is at his best, streamline operations, such as planning, preparation, wiring, testing, validation, the steps to ensure the quality of system operation and management will be of great significance.
