Fiber distribution box transmit signals through light waves. It is made from either glass or plastic fiber where light passes through. At the end of every fiber optics cable is a transmitter. When information or signals pass through this transmitter, it is converted to a LED that passes through the cable.The fiber optic cables have many advantages. It is more security and reliable than any other wire available. The fiber optic cable is in the high voltage environment. Dry-band voltage of the polluted sheath's surface of the all-dielectric self-supporting fiber optic cable is analyzed in this paper.Most fiber optic cables are designed professionally and are meant to work effectively for a long time. Just like any other units, the cables develop problems and it's up to you to identify and fix them. To help you out here are some of the most common fiber optic fiber problems.External damageCommon external damages are splits and scratches on the units. The units are highly sensitive; therefore, even the most minor damages have the ability to prevent effective transfer of signals. If you have noticed some defects on your units you should replace them as early as possible.Improperly installed connectorsConnectors join two or more cables and play a vital role in determining the effectiveness of the optic cables. It's common for some contractors to improperly install the cables resulting to cable problems. To fix the problems you should hire an experienced contractor to install the cables properly.StretchingIt’s wrong to have optic cables too long or too short. As mentioned, the cables are very sensitive and even a minor damage can prevent the cables from working properly. To prevent the cables from stretching you should ensure that you install them at the right place. You should also avoid pulling the cable jacket during installation. The best way of going about it is using grips at the connectors.Old ageJust like anything else under the sun fiber optic cables get old. Old cables are not only ineffective in their working, they also tend to develop problems every now and then. When your cables are old, the best way of fixing them is replacing them.
