Tele-Optics has been in the forefront of this technology since the beginning. Bandwidth is an effective measure of the rate at which information can be sent. Low loss Loss indicates the amount of data-deterioration that occurs over a given distance. All mediums suffer some loss. Electromagnet immunity Copper cables radiate and pick up electromagnetic radiation.
Copper conductors act like antennae, either transmitting or receiving electromagnetic energy.
Fibers do not radiate or accept electromagnetic energy, and make an ideal trans-mission medium in environments that have a high level of EMI, such as in factories. A fiber-optic cable with the same information carrying capacity as a copper cable weighs much less than the copper cable. A single fiber can often replace several large copper conductors. The small size of fiber-optic cables makes them attractive for applications where space is restricted. Security Optic fibers do not radiate energy that can be received by a nearby antenna, and fiber-optic transmission are extremely difficult to tap.
