Fiber optics


Today the world of fiber optics is bigger than ever. What is available to the engineer and the technician is now only apparent to the well informed. Not all engineers and technicians have a background or an education in the field of fiber optics. This report is intended to be an informative preliminary guide to those readers whose interest lies in the field of fiber optics.

The advantages of fiber optic systems are discussed and compared to conventional systems. Although a fiber optic system includes transmitters and receivers, this report concentrates primarily on fiber optic connectors and cables. It also includes a look at the characteristics of the fibers themselves.

The basis for this report is information obtained from a survey taken from a select number of manufacturers of fiber optic connectors and fiber optic cables. Available fiber optic connectors range from reusable to permanently installed, cheap to expensive, plastic to stainless steel. Some require special tools and preparation including the use of epoxy, whereas others can be used in the field quickly without any special tools or epoxy. Since many connectors, however, require epoxy, this report introduces six different types of epoxies, showing their characteristics and listing their applications.

The fiber cable has become a widely appreciated medium for data and information transmission systems. The consumer has many choices from one or two fibers per cable to a bundle fiber cable. The cables have many designs which lead to various applications. These cable designs and their characteristics are summarized and discussed.

There are many other optical devices that are available and on the market. Among these devices were not covered in this report, the coupling from one fiber to another (attached side by side) was investigated theoretically. The case where internal reflection in the fiber’s core created an evanescent field in the cladding (this is when the angle of incidence is greater than the critical angle) was emphasized. This shows that the power in the evanescent field is imaginary (reactive), and the angle of refraction is also imaginary. However, when the evanescent field extends on out to the second fiber’s cladding, and continues until it reaches and enters the second fiber’s core, power then exists; thus, optical power was transferred by way of an evanescent field.
