In optical communication, important blocks of point-to-point links include the light source (typically a laser), which generates the optical signal; the optical fiber, which transmits the signal over distances; and the photodetector, which converts the received optical signal back into electrical form. Additional components may include amplifiers to boost signal strength, multiplexers and demultiplexers for combining and separating multiple signals, and various types of connectors and splices for ensuring effective signal transmission. These elements work together to ensure efficient and reliable communication over optical networks.
In the U.S.A it means you have the right of way but proceed with caution.
If you mean a gesture/action/sound to convey information then, Message, gesture or warning
signal
"Signal" is the verb.
A fiber optical signal is based on the transfer of photons, while an electrical signal is based on the transfer of electrons.
electrical signal can be converted to an optical sigal by using a LED or SOA(semiconductor optical amplifier). LED is the cheaper option but have the drawback of larger linewidth. Typically used for LAN (local area network). SOA produces an optical signal mostly by direct modulation tecnique .

Detector converts optical signal to electric signal
Optical signals (usually on the infrared band) optical s ignals generally mean visible light... so it mainly uses visible light.

Long Distance signal transmission!
a continuously variable signal. it could be electronic, mechanical, hydraulic, optical, etc.
only over fiber
The retina detects light and the optical nerve sends the signal to the brain.
Laser clipping primarily occurs in an optical transmitter. It happens when the input signal to the laser exceeds the maximum output level that the laser can produce, leading to distortion and a nonlinear response. This can result in signal degradation and loss of information integrity. In contrast, optical receivers generally deal with signal detection and amplification rather than generating light, so clipping is not a relevant issue in that context.
No. As long as the signal is getting through, the gauge of the optical connection makes no difference.
