The biggest advantage of optical fiber is the fact it is the most cost effective means of transporting information. Fiber can transport more information longer distances in less time than any other communications medium, as the photo on the left from the late 1970s illustrates so well.

These advantages makes the use of optical fiber the most logical choice in data transmission.Twenty five years ago, fiber was just being introduced. It was expensive and required PhD's from Bell Labs to install it while copper wire was easy to install. Today most communications installers do fiber and wireless as well as copper.

That's what the FOA is all about. We have hundreds of FOA-approved schools offering FOA certifications. About 25,000 students have been certified by FOA schools (10/2008.)Around the world, FOA is recognized as the leader in fiber optic education and certification.

You might think that eye damage from working with lasers would be the big concern in fiber optic installations. The reality is that high power lasers burning holes in metal or burning off warts mostly have little relevance to your typical fiber optic installation. Optical sources used in fiber optics are generally of much lower power levels (The exception is high power DWDM or CATV systems). Of course, you should always be careful with your eyes, especially when using a fiber optic microscope which can concentrate all the light from the fiber into your eye. NEVER look into a fiber unless you know no light is present - use a power meter to check it - and anyway, the light is in the infrared and you can't see anything anyway!

The real safety lecture will always be about small scraps of glass cleaved off the ends of the fibers being terminated or spliced. These scraps are very dangerous! The cleaved ends are extremely sharp and can easily penetrate your skin. If they get into your eyes, they are very hard to flush out. Don't even think about what happens if you eat one. Always wear safety glasses whenever working with fiber and always carefully dispose of all fiber scraps!

Fiber optics refers to the technology of transmitting light down thin strands of highly transparent material, usually glass but sometimes plastic. Fiber optics is used in communications, lighting, medicine, optical inspections and to make sensors. The FOA is primarily interested in communications fiber optics, so this book will focus on that application.
