There are many different active and passive components that make up an optical network. A solid understanding of the function of these components is vital when designing a cost-effective optical network that will meet the bandwidth needs for many years to come. The CouplerThe optical coupler is often called a splitter and is depicted in Figure 1. It is a passive

Attenuation and dispersion are the two critical characteristics that determine the maximum distance an optical signal can be transmitted before the receiver is unable to detect it. AttenuationCompared to conventional transmission media the most attractive feature of fiber optic cable is its extremely low signal attenuation. The attenuation profile of a fiber is

The optical fiber is made up of two concentric cylindrical strands of silica surrounded by a plastic coating. The center most silica strand is the cone of the fiber with a refractive index1 of approximately 1.48. The core of the fiber physically transports most of the optical power. The core is surrounded by another strand of silica called the cladding. The

Three basic types of fiber optic cable are used in communication systems: 1. Step-index multimode 2, Step-index single mode 3, Graded-index Step-index multimode fiber has an index of refraction profile that “steps” from low to high to low as measured from cladding to core to cladding. Relatively large core diameter and numerical aperture characterize this fiber. The core/cladding diameter of a

Fiber optics is a medium for carrying information from one point to another in the form of light. Unlike the copper form of transmission, fiber optics is not electrical in nature. A basic fiber optic system consists of a transmitting device that converts an electrical signal into a light signal, an optical fiber cable that carries the light, and a receiver that accepts the light signal and

The most commonly used optical source is the LASER diode (Light Amplification by Stimulated Emission of Radiation). Physically, a laser converts electrical current to light, which is in turn coupled into an optical fiber. An important characteristic of a laser is its threshold current. A typical current Vs optical output power is shown in figure 6.&nbsp;

Fiber-optic communication is a way of transmitting information from one place to another by sending light all the way through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. First developed in the 1970s, fiber-optic communication systems have revolutionized the telecommunications industry and played a major role in the advent of the

Physics of Total Internal Reflection&nbsp; Consider a ray of light passing between two media of different refractive indexes n1 and n2 as shown in figure 3. If n1&gt; n2 the light ray as it passes from one media to the next will bend away from an imaginary line (the normal) perpendicular to the media’s mating surface. Conversely if n1 &lt; n2 then the ray will

Since its invention in the early 1970s, the use and the demand of optical fibre has grown immensely. Today, the uses of fibre optic are quite numerous. The most uses are popular in telecommunications, medicine, military, automotive and industrial. The improvement for this technology still in progress and it will always be upgrade days by days.
