Optical fiber jumpers are widely used equipment connection accessories in the field of optical communication, and their role in optical fiber transmission wiring should not be underestimated. Therefore, understanding the necessary usage and precautions is an indispensable step to help ensure high-quality fiber transmission quality and improve fiber durability. This article will introduce you specific operation guidelines and related suggestions from the three aspects of fiber jumper connection, disconnection and daily maintenance, so as to help you avoid unnecessary trouble and loss in fiber optic wiring.
Optical fiber jumper connection and disconnection method
Fiber patch cords can be used to connect a variety of network equipment and devices with fiber optic interfaces, such as optical modules, adapter panels, distribution boxes, wavelength division multiplexers and demultiplexers, and fiber optic transceivers. The following will take the common jumper to connect the optical module on the switch as an example to introduce the general operation steps in detail.
Fiber jumper connection steps
Remove the dust caps from the connectors at both ends of the optical module and fiber jumper, and save them for future use.
Insert the jumper connector correctly into the module.
Use cable ties to tie the fiber optic cable part tightly and shape it to protect the jumper.
Fiber jumper disconnection steps
Run the command to shut down the switch port where the optical module is inserted.
Carefully unplug the fiber jumper connector from the module.
Cover the connectors at both ends of the fiber jumper and the optical module interface with dust caps respectively.
Precautions:
Installers need to have sufficient technical knowledge and experience in network wiring to ensure installation quality and safety.
Be sure to wear protective gloves and an anti-static wrist strap when handling active devices to prevent fiber fragments and electrostatic damage.
Always ensure that the fiber optic connector end face is clean before use.
When using, pay attention to the bending radius of the fiber jumper. Excessive stretching or extrusion may cause loss.
Do not allow the jumper to be hung or placed at will from the device to prevent damage when the jumper is accidentally pulled.
Avoid frequent insertion or removal of jumpers in the device to reduce wear and tear.
When connecting, do not look directly at the end face of the jumper connector to prevent the laser from hurting your eyes.
After installation, the work area should be thoroughly cleaned.
Optical fiber patch cord maintenance method
Although the use of fiber jumpers is simple, its daily maintenance cannot be ignored. Proper cleaning and maintenance not only ensures smooth signal transmission, but also prolongs the service life of optical fibers to a certain extent.
Clean fiber jumpers in time
Why is fiber patch cord cleaning so important? An industry survey by a telecom giant identified connector contamination as the leading cause of network failures. It can be seen from this that once the optical fiber is polluted by dust, oil stains and other substances, the transmission quality of the optical signal will be greatly reduced. In addition, metal particles produced by the abrasion of the connector body and the optical fiber shell may also block the optical fiber, resulting in signal loss and loss to the user. Therefore, it can be said that optical fiber jumpers are actually very "fragile", and timely cleaning is essential.
Generally speaking, fiber patch cord cleaning is mainly aimed at the connectors at both ends. There are two main cleaning methods, dry cleaning and wet cleaning. The two are slightly different and can be used together. Commonly used dry cleaning tools include cassette-type optical fiber cleaning boxes and one-touch cleaning pens, etc., and wet cleaning tools include dust-free wipes, cleaning sticks, and the like.
Reasonable storage of fiber jumpers
The first thing to remember, whether or not a patch cord is in use, is: Do not bend or stretch it excessively. This is a common mistake everyone makes, and the worst result is a damaged jumper. Some damage caused by bending is visible to the naked eye, however, the loss may not be easily judged in some cases, for example, micro-deformation of the fiber caused by ultra-low temperature, millimeter-level displacement caused by buffer or jacket defects, poor installation or other. factor. Because such damage is not directly detectable, it is often overlooked and can lead to bigger problems in the long run. To avoid further losses, when jumpers must be replaced, the following factors should be considered:
Never bend fiber patch cords beyond their minimum bend radius, especially in tight spaces with high-density fiber optic cabling.
Re-route fiber patch cables to protect cables from breakage with suitable tools, such as horizontal cable management racks, etc.
Do not bump the fiber optic connector, otherwise the end face may be worn and the debris may stab the skin. Therefore, it is recommended to put a dust cap on the jumper at any time.
For equipment to detect and identify faults, such as breakage and total attenuation inside fiber optic patch cords, optical time domain reflectometry (OTDR) and fiber optic microscopes can be used.
