A World of Free Space Optics Applications and Security


When considering the use of wireless optics it is important to explore free space optics applications and security. There are so many applications for this type of technology and it offers a secure environment as well.

One of the original uses of free space optics was in the Navy. Naval communications from ship-to-ship have been accomplished with free space optics for years.

One of the most pressing and important uses for the technology these days is in the private and public sectors. Many businesses and universities have problems getting connected because the fiber optic cables do not run all the way to the facility, but instead stop a mile or so away.

That last mile is critical and the use of free space optics applications and security can easily bridge that last mile and ensure that more businesses and institutions are able to connect and communicate. This means that the current use for this technology tends to be over shorter distances.

There are a number of entities that are able to take advantage of free space optics, including educational institutions, health care facilities, the government, cities, and corporations. Building-to-building communications within a confined area can easily be made possible with free space optics.

But what about the security risks, you ask? In unregulated space, wouldn't there be risks associated with security? With free space optics applications and security, a secure environment is easier to maintain than one might think.

One of the security risks of wireless transmissions is the interception of data. The broader the signal, the easier it is to intercept. Free space optics allows for a much narrower signal than traditional wireless methods of transmission and it stays narrow for the whole journey, which means there is a lower security risk.

With free space optics there is also an absence of what are termed side lobes, which is energy that is lost to the sides and back of the signal. This lost energy carries the same signal as the main transmission and this means it can be picked up by someone other than the intended target.

Another natural security feature of free space optics is the need for an uninterrupted signal between units. If the signal becomes blocked for any reason, including by a detector, the transmission will automatically end.

Thus the only way to pick up the signal that is being sent is to detect it behind the unit that is receiving the transmission. It is highly unlikely that this would be attempted, but the signal can be made to stop at the unit rather than extend past it and thus no one would be able to pick up the signal in that fashion.

Even a chance interception of the signal is rare and the signal is very difficult to decode should it be intercepted. This means that when it comes to free space optics applications and security there is very little worry about there being an issue. The method of delivery of the transmission automatically takes care of the security concerns.
