Fiber Wavelengths

What is the science behind fiber optics?

Optical fiber strands are actual incredibly thin strand of glass. These long strands are incredibly thin threads. The strands are bound together lengthwise in bundles and they are then referred to as optical cables. Light signals are then sent across these very long cables from starting points to their final destinations. The light signals have the ability to travel very long distances at a rapid speed.

If you were to cut into or through an optical cable you would notice its core. This is where the glass is and this is where the light travels. Then there is a cladding material that surrounds the core and consistently reflects the light into the core as it travels along. Imagine for a moment a pipe with many twists and bends that you would like to send a stream of light down. How could you do this without getting the light stuck shining on the wall in front of you and not shining down to ever reach the end of the hall? You would line the hall with mirrors. This way the light would reflect along down the hall bouncing back and forth and picking up reflections until it lit the end of the hall. Lastly, in the construction of the cable, there is a plastic outer coating know as buffer coating. As you can assume, the buffer coating is there to protect the fiber from obvious things such as external damage, tearing or water.

There are two basic types of optical fibers – single mode and multi mode fibers. A single mode fiber sends laser infrared light through its small core. A multi mode fiber sends LED light infrared through a large core. There is a third unique type of optical fiber that is made from plastic. These optical fibers send a visible LED light that is red through a large core.

Casey Wedge

My name is Casey Wedge and I have been with Fastblue for a few years now. I have maintained a few different positions within the company and although I am currently the Regional Manager of Sales. I am very fond of writing and like to stay up to date on whats going on in the world of Telecom.

Aside from work, I have played hockey my whole life so I am decent on the rink and a very average mountain biker. Breakfast foods are my favorite and I enjoy spending time with many fellow UCSB Gaucho Alums – Olé!
