The easiest way to figure out fiber optics at least at the basic level is to get an explanation of the process. Fiber optic technology works by having engineering meet science head to head. Light is then sent through optical fibers via total internal reflection. The fiber’s core is then taken care of by a process called cladding. Cladding occurs when substances of a lesser refractive index become closer to a greater refractive index’s core material.
The detachment of the core and cladding could be an instant thing or there may be a buildup to the two coming undone. The refractive index is a way of figuring out the light speed of a substance. Inside of a vacuum the light travels at its top speed. Let’s think outer space for a second. In that case speeds can reach up to 186,000 miles per second.
The figuring out of a refractive index happens when the vacuum’s speed of light is divided by another medium’s speed of light. The core’s value ends up around 1.48. The end result for the refractive index is 1. The cladding for an optical fiber is 1.46. When a greater refractive index occurs the light moves even slower. How else does fiber optic technology work, read on!
When light travels inside an enclosed medium the light is cloned when it comes into touch with a steep angle. Therefore optical fibers can hold onto the light that’s within the core. When this happens the light bounces inside of its set limits. Timing is crucial for this light travel and if the timing is off the light travel will be immensely hindered inside of the fiber. Inside of what is called the acceptance cone there are angles that work within the fiber. The acceptance cone’s size is the result of the refractive index’s difference between the cladding and core of the fiber. In short, there’s only so much that an angle of light can do to enter a fiber. This is to keep the light circulated inside the central part of the fiber and do what it needs to do.
Fiber optic technology riles on the use of three different grades of fiber and each fiber is intended for different applications. The first are single mode fibers and they’re made solely of glass and are used for optic based networks that go a long instance. The next type of fiber is multi-mode fiber, which is sometimes made with a hybrid of plastic and glass or just glass only. Multi-mode fiber is made for networks in a 500 meter range. Of the two, single-mode is the costlier of the two. Then there’s special-purpose optical fiber such as photonic crystal fiber that’s used to bend light in order to keep it inside of the fiber.
Well that’s a wrap and we hope that fiber optic technology hasn’t scared you because it truly is amazing! Its inner workings are vast and in depth. We hope that this article serves as a suitable jumping point for a subject that is of great variety and interest until next time thanks for reading!
Video & Fiber Optic
CCTV cameras, a DVR and maybe a security officer are just not enough anymore. Chemical and pharmaceutical companies, schools, corporations and utility services are looking for more accurate, cost effective ways to secure life and property.
Enter Fiber Intrument Sales of Oriskany, New York and Sandia National Laboratories. FIS and Sandia developed the patented Fiber Fence fiber optic intrusion detection and perimeter security system.
Fiber Fence can detect and locate intruders anywhere along a fence line up to 10 miles in length further if multiple units are networked together. The System can be installed on existing objects such as perimeter fencing, walls, and gateways. An alert occurs when someone causes a disturbance to the optical fiber, or to the Mouse Trip sensor to which it is attached. Fiber Fence is relatively inexpensive, and very easy to install. System includes an OTDR for system monitoring and testing.
If the fence takes a direct electric strike from lightning or transformer near the perimeter, Fiber Fence will continue to work. There will not be any expensive electrical components to change.
Another fiber optic security system, part of the Fiber Fence family, is Cover Cop. A non electric sensor that will guard against any intrusion to a manhole or utility cover.
Mr. Richard Martinez, CPP - President and CEO of Homeland Protective Group, Inc. in New York City states, "Fiber Fence and Cover Cop, when integrated with the FIS Strike Zone Software, provides the ultimate form of security for correctional institutions, military installations and any other sensitive areas requiring perimeter security."
The benefits of Fiber Optic Security-
Applications - Fiber Fence and Cover Cop are ideal for large perimeters such as those around factories, water reservoirs, electric grids and airports. Fiber Fence has been installed to protect military facilities, nuclear power facilities, factories, storage yards, hazardous waste facilities and more. Since the system requires no additional electric to the fence line, it is much more afordable than other systems.
Anti-Spark' Optical Technology - The mechanical detection mechanism, called Cover Cop, is a hermetically sealed sensor that does not use electricity. It can't spark an explosion in underground utilities where combustible gases may be present.
Affordable Protection - Up to 500 or more utility covers can be monitored within a single system, over a distance of 80 or more kilometers. These monitoring distances are many times that of electronic systems, and eliminate the need for expensive inline repeaters to amplify the signal. Power is NOT required at the protected entrances or anywhere along the cable run.
The patented Strike Zone Security Solution combines advanced optical technology with specialized sensing devices and high tech security systems to achieve performance and reliability superior to other intrusion detection systems. Adopted by the U.S. Military, The Fiber Fence can monitor up to 16 km (10 miles) of fence line without requiring power anywhere along the perimeter. Systems can be cascaded to provide monitoring distances of up to 80 km (50 miles)
