A fiber optic span is a type of cable that is used to transmit light signals over long distances. It is made up of thin strands of glass or plastic that are bundled together and surrounded by protective material. Each of these strands act as an individual optical fiber that transmits light from one end to the other. The light is sent through the core of the fiber by a process called total internal reflection which ensures that the light is reflected back and forth between the core and the cladding.
A fiber optic span consists of a transmitting end and a receiving end. At the transmitting end, a transmitter is used to convert electrical signals into light signals. These light signals then travel through the core of the fiber optic span and are detected at the receiving end. At the receiving end, a receiver is used to convert the light signals back into electrical signals.
Fiber optic spans are used in a variety of applications such as telecommunications, data transmission, video transmission, and even medical imaging. They are generally preferred over traditional copper cables due to their higher bandwidth capabilities, lower power requirements, and improved signal integrity. They are also less susceptible to interference from electromagnetic fields such as those created by power lines, making them an ideal choice for applications where interference is a concern.
Fiber optic spans are also much thinner than traditional copper cables and require less space for installation. They are also much lighter and more cost-effective, making them a preferred choice for many applications. In addition, fiber optic spans are also much more reliable than copper cables, as they are less likely to experience signal degradation over long distances.
