Fiber Optic connectors and cables are present in nearly every communications project that we might sell into, be it a DAS installation or a Base Station with wireless backhaul, you can be certain that fiber jumpers and cabling are being used somewhere in that network. Having a general understanding of fiber optics and the different fiber and connector types that are available will allow you to have a more productive conversation with your customer.
Some Fiber Basics: Transmitting Signals with Light
Digital Light Signals – Lasers inside the equipment generate the light that the fiber cables carry.
Just as copper cables use pulses of electricity to carry signals across a copy wire, Fiber Optic cable uses pulses of light. For digital communication we transmit in ones and zeros. For copper, the difference between a one and a zero is a change or variation in the electric pulse within a certain acceptable range. To keep it really simple, the presence of a pulse at a certain time is a one (1) and the absence of a pulse is a zero (0). The same principle is used for fiber optics only instead of electrical pulses we use pulses of light. A laser source inside the hardware is used to turn the light on and off. For Fiber Optics, again keeping it as simple as possible, the presence of a light pulse at a certain time is a one (1) while the absence of a light pulse is a zero (0). To further simplify it – light on = 1, light off = 0.

The Optical Core – a glass tube (core) propagates the light signals through the fiber cable.
Glass is inherently reflective and is a perfect medium for transporting light. Because of this, fiber optic cables use a glass tube (core) in their center to transport the light pulses generated by the lasers. These light pulses travel (propagate) down the glass core by reflecting (bouncing) off of the sides. Other than the original laser, the transported signal does not require any power whatsoever, the light reflecting inside the core is what carries the signal through the fiber cable. The signal does weaken the farther it travels and will eventually need to be regenerated but not before it has traveled quite a long way. Some fiber optic cables can carry signals for 60 miles or more before they need regenerated.
