Communication is the most essential aspect of our lives these days. Be it mobile phones, emails, and so on., the primary idea is to transfer messages from one point to another at superb speeds. This transmitting of signals is performed through transferring mediums. The medium can be of 2 models:-
– ” cable ” transmission mediums
– Wireless transmission mediums
Among the cable transmission mediums one can choose from twisted wires, copper wires, fiber optic cables and several more. Fiber optic cables are mainly used to carry light. The cable is not a single wire, but on the other hand is a set of individual wires where every single wire is given a plastic-type coating. The whole cable is also given a protective covering according to the natural environment where it will be used. The environment of app will determine the strength, resistibility and flexibility of the wire. The material used is generally plastic or glass, depending on the variety of transmission. For shorter range, plastic is used whereas for medium and very long range, glass is used.
The optical system has three parts:
Optical transmitter
Optical receiver
Actual optic medium linking the transmitter and the receiver
The optical transmission device may be a laser, coherent light source or a light emitting diode. The real distribution of light thru the optical fiber is based on Maxwell’s formula.
Fiber optic cables are applied for various purposes which range from long distance tele-metering to fast information transmission from one node to some other within a building. There are numerous benefits of using fiber optic cables. Several of them are as follows:
Not influenced by electro-magnetic disturbance
There is no or quite little fiber crosstalk. Therefore data protection is maintained
Multi-plexing of significant number of signals is possible as high frequency bandwidths may also be used
Offer basic safety in hazardous areas
Much more practical as compared to other wired mediums
Much less ground loop issues are present in this kind of transmissions.
For some particular purposes, color coded cable are accessible. In total TWELVE colors are used in the cable markings. Every single color has its own specifications known to the professionals handling all of them. This technique makes it easier to use such cables and prevents problems.
These days hybrid cables are also used which are a combine of fiber optic cables and electrical wires. In these types of mixed cables, information and power are transmitted together.
Fiber optic cables are the best option, if performance and safety are recommended.It is one of the crucial points to keep in mind.
