Fiber Optic Cables – The Multi-Mode Cable

Compared to the single mode cable, the multimode fiber optic cables have larger cores. There are many technologies which this can be used including internet and cable TV connectivity.

The multimode fiber can allow up to 100 MBS bandwidth over short to medium distances. The single mode cables are the ones which are depended on for long distance communications and networking. The light waves in the multimode fibers are dispersed into several paths as they travel through the inner core. However, because it has a bigger core, one problem that may be met is the overlapping of the light pulses which go through it. This is why this fiber optic cable is only good for the short distance as the longer the data has to be transmitted, the more potential losses may have to be considered. This is one reason why internet connections now require the single mode cable for there is less damage to data, the data is more complete and the signals are clearer.

It really depends on the cable TV companies, but they may offer fiber optic cable TV using either the single mode cable or the multi mode cable. As previously mentioned, the shorter the distance is from the server to the receiving point the more the companies would choose to use the multi mode cable; for one thing, this is much cheaper compared to the single mode.

The applications for fiber optic cables have increased rapidly thought the years, ever since the first of the systems were installed in the late 70s. It was the telephone companies which first benefitted from this technology when they replaced their old copper wires to the fiber optic cables. Today, almost all telephone companies around the globe use fiber optic cable systems as the foundations which their local and long distance connections.
