Kinds of Optical Cables Available in the Market
There is a single mode and multi mode cable, both basically performing a rather similar task. The names right away tell the difference between the two.
• A single mode cable emits only one beam or one color of light. This type of cable sends data through this single beam of light. Interference is avoided because there is only a single ray of light. This means that a single mode cable can send data across long distances. Single mode optical cables are more popular in the market. They come in various lengths, and they are more adaptable, being able to perform a wider range of tasks.
• A multi mode cable simultaneously emits several beams of light, with each beam sent at a different angle so that interference between beams cannot take place. This nature of beam transmission is sensitive. Because of the sensitivity of the multiple beam mechanism, multi mode cables are usually only used for short distance data transmission to avoid disturbances. The two cables have roughly similar designs though.
There are other types of optical fiber cables. It is the construction of these cables that makes them different. Regardless of the type of optical cable, its main function is to transmit data. All optical fiber cables are basically the same in terms of essential component and function. However, it is important to note the differences, because one cable may be more appropriate than the other on an occasion.
Besides single mode and multi mode cables, there are also the loose tube cables. As the name implies, these have no insulation. The optical fibers are bare or are only covered thinly. They may only be insulated against water or chemicals by a special insulating gel. Loose tube cables are used for outdoor or underground transmission systems.
Tightpack cables are composed of a large bunch of optical fiber wires that are sorted into several sets. These are covered in usual cable insulation, but each fiber set has no protection. A special termination unit is required for every fiber set to stop connections. This type of cable is only apt for short distance transmission purposes.
A simplified version of a tightpack cable is the simplex cable, which makes use of one or two big optical fibers. This allows simple operation and lower energy usage. Outdoor and heavy-duty simplex cables are coated with hard-wearing insulation.
These types of cables can confuse and trouble carefree homeowners. Note that your devices at home may be using optical fiber cables. If you are enjoying your PC and internet, you are most likely enjoying the benefits provided by optical fibers.
