Final answer:
A major concern when working with fiber-optic cable is maintaining low loss through total internal reflection, ensuring high bandwidth, and reducing crosstalk for effective communication signal transmission.
Step-by-step explanation:
When working with fiber-optic cable, a major concern is ensuring that there is no loss of signal quality, which is achieved through the principle of total internal reflection. The fiber is designed with a core that has a higher index of refraction compared to the surrounding cladding, preventing light from being transmitted between fibers in a bundle. This design ensures that light is propagated along the length of the fiber with minimal loss, a property known as low loss. It is crucial to maintain the integrity of this structure to avoid issues such as signal attenuation or data corruption. Additionally, the high bandwidth and reduced crosstalk are essential characteristics of fiber-optic cables that contribute to their efficiency in transmitting telephone, internet, and cable TV signals. A major concern when working with fiber-optic cable is the prevention of signal loss.
Optical fibers are designed to transmit light signals over long distances, but any disruptions or damage to the cable can result in a loss of signal strength. This can happen due to factors such as bending the cable beyond its maximum bend radius, sharp bends, twisting, or damage to the protective cladding. Another concern is maintaining the quality of the light signal. Any contaminants or impurities that enter the fiber-optic cable can scatter or absorb the light, causing signal degradation. This is why strict cleanliness and proper installation techniques are crucial when working with fiber-optic cables. Finally, fiber-optic cables are sensitive to excessive tension or stretching. Overloading the cable with excessive tension can cause the fibers to break, leading to complete signal loss.
