Can a CATV laser modulate audio?
Now, that being said, there are lasers that are used in CATV transmission that are indeed amplitude modulated by the RF output of a CATV headend. So, technically, you could amplitude modulate an audio signal on the laser and change the “volume”. (Those CATV lasers operate at 1310 nm.) 4.8K views.
Does optical cable reduce volume?
The signal in an optical cable is a digital light and the reduction of the glow does not reduce the volume. The Digital optical signal needs to be decoded first to an Analog one, and the circuit used would also need a logarithmic resistance control for its volume control. 140 views.
Is the volume of a laser signal digital?
Typically the signal going through the optical cable is digital. The volume information if the data is music is contained in that digital signal. So, although volume is not in any way by how bright the laser signal is, it is controlled by the data contained in the transmission.
