There are three major wavelengths as far as fiber optic communication is concerned: 1550nm, 1310nm, and 850 nm. These operating windows are of typical operating length. The specific ranges are 1550nm having 1500nm ~ 160 nm, 1310 nm having 1250nm ~ 1310 nm, and 850nm having 800 nm ~ 900nm. These are not randomly selected operating windows. Each is chosen to best suit a given fiber optic cable or collection of cables.
A fiber optic color code refers to which light wavelengths they’re suited to, since certain optical fibers are only suited to certain colors and wavelengths. There are ranges by which the fiber operates best and you should know which operating window or wavelength range you should turn to. Every window is centered on a typical operating wavelength.
The Basics of Fiber Optics
- Fiber optic setups include tubes with rear and front surfaces that facilitate extra cable protection and better management. Meanwhile, the cable itself transmits photos to a second quantum dot that sit between two mirrors. The reflective surfaces catch the photon and bound it off the dot until absorption occurs. The cable also has a stripped end that bares the fiber and extends it into the connector via the ferrule. That’s how fiber optics beat out copper wires in terms of faster data and energy transmission. This process has made electronic wiring technology even more sophisticated and reliable than ever before.
- The only thing better than fiber optics in existence is graphite, which is an emerging technology that people should be on the watch out for in the coming decades. As for frequency, it refers to the fiber optic system’s light source modulation speed. Your fiber optic color code, to recap, should deliberately select the right operating windows in order to get the best match and performance for it. In turn, it should also look for the right frequency, which is measured in hertz or a pulse per second. Every setup, from your computer to your LCD TV, has a hertz setting you must comply with.
- The optical fiber system operates in megahertz or gigahertz because of its sheer amount of capacity. To be more specific, fiber optic cables are able to handle millions of pulses or billions to trillions of pulses every second. You should know the MHz or GHz speed you system operates on to maximize your investment and make sure everything works properly, because if you get specs wrong, it simply won’t run whether it’s cable television or your Internet connection. As for attenuation, it’s something that describes the optical power loss as light travels through the wire.
- Attenuation, measured in dB, is important because it also calculates and regulates how efficient your fiber optic cable is at delivering electricity and data to your PC, laptop, television, and Internet phone (VoIP). 10Log(Pout/Pin) is the definition of dB. For instance -3dB attenuation can be achieved from a power loss of 50%. Attenuation loss in your optic fiber connection should be taken into consideration when dealing with long-distance fiber optic systems. The standard acceptable mode fiber dB is 0.2dB attenuation every kilometer. It should stray from that particular figure.
