Optical communication is any type of communication in which light is used to carry the signal to the remote end, instead of electrical current. The SNR ratio related to the optical communications has its own specifics. Depending on where the PON terminates, the system can be described as fiber-to-the-curb ( FTTC ), fiber-to-the-building (FTTB), or fiber-to-the-home ( FTTH ). The electric field is defined at each point in space as the force per unit charge that would be experienced by a vanishingly small positive test charge if held stationary at that point.
