Abstract:
1. An apparatus for receiving power and data signals using an optical signal within a predetermined wavelength range, the apparatus comprising: a first optical receiver configured to be optically coupled to an optical fiber carrying an optical signal and configured to receive least a first portion of the optical signal, wherein the optical receiver is operative to convert the intercepted first portion of the optical signal into an electrical signal and to provide the electrical signal as an output; an electrical filter including a low pass filter portion, the electrical filter having an input electrically coupled to the output of the optical receiver receiving the electrical signal therefrom, the electrical filter being operative to low pass filter the received electrical signal and further operative to provide the low pass filtered electrical signal as a power output signal; a second optical receiver configured to be coupled to the optical fiber and configured to intercept at least a second portion of the optical signal guided by the optical fiber, wherein the second optical receiver is operative to convert the intercepted second portion of the optical signal into a second electrical signal having a data portion and further operative to provide the second electrical signal as an output; and a power combination module having a first and second power inputs, and a combination power output, the first power input coupled to the power output signal from the electrical filter and the second power input coupled to an external power source and receiving external power therefrom, the power combination module operative to combine the power output signal and the external power signal into a combined power signal and to provide the combined power signal as a power signal output.
