Communication Systems/Fiber Optic Systems
Long haul trunks were the first application of optical fiber to gain universal acceptance. Three alternate methods are coax (copper), terrestrial microwave and satellite. While microwave towers can be used to bridge relatively small bodies of water, cables or satellites are needed to span oceans.
Telegraph cables were first deployed in the mid-1800’s and the first successful trans-Atlantic cable was laid in 1858. For 100 years copper submarine cables were the principle means of communication between North America and Europe. In the 1960’s satellites gained ascendancy but today fiber cable dominates.
Fiber cable has some significant advantages over satellite technology:
• Fiber systems can be repaired, geo-stationary satellites cannot
• Fiber systems have a slightly longer life expectancy
• Fiber systems can be upgraded while in service
• Fiber deployment has a lower risk than launching a satellite
• Fiber propagation delay is significantly lower than satellites
The core of a conventional optical fiber is a cylinder of glass or plastic that runs along the fiber's length. The core is surrounded by a medium with a lower index of refraction, typically a cladding of a different glass, or plastic. Light travelling in the core reflects from the core-cladding boundary due to total internal reflection, as long as the angle between the light and the boundary is less than the critical angle. As a result, the fiber transmits all rays that enter the fiber with a sufficiently small angle to the fiber's axis. The limiting angle is called the acceptance angle, and the rays that are confined by the core/cladding boundary are called guided rays.
