![]() "A 19-inch rack is a standardized frame or enclosure for mounting multiple equipment modules. The vector stencils library "Rack diagrams" contains 33 rack design elements for drawing the computer network server rack diagrams. The symbols example "Cisco optical - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park. The process of communicating using fiber-optics involves the following basic steps: Creating the optical signal involving the use of a transmitter, relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak, receiving the optical signal, and converting it into an electrical signal." ![]() Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals. Because of its advantages over electrical transmission, optical fibers have largely replaced copper wire communications in core networks in the developed world. The light forms an electromagnetic carrier wave that is modulated to carry information. ![]() "Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The vector stencils library "Cisco optical" contains 19 symbols of optical devices for drawing Cisco computer network diagrams. ![]()
