FIBER OPTIC COMMUNICATIONS
Fiber Optic Data Transmission Systems Fiber optic data transmission systems send information over fiber by turning electronic signals into light. Light refers to more than the portion of the electromagnetic spectrum that is near to what is visible to the human eye. The electromagnetic spectrum is composed of visible and near -infrared light ...
