Which of the following fiber-optic cable types use light emitting diodes (LEDs) as a data light source transmitter?
|
multi-mode
|
|
single-mode
|
|
Either A or B
|
|
None of the above
|
Explanation:
Detailed explanation-1: -In the case of multimode optical fiber, the core-to-cladding diameter is 50-62.5 to 125 micrometers. The diameter of the core is large enough to allow several light rays to transmit through it, and it uses an LED as its optical source.
Detailed explanation-2: -Fiber optic cables carry communication signals using pulses of light generated by small lasers or light-emitting diodes.
Detailed explanation-3: -A fiber optic cable is a type of cable that uses light to transmit data over long distances. It consists of a core made of glass or plastic that is surrounded by layers of protective material, such as cladding.
