An apparatus and method for measuring power and power losses of light transmissions in fiber optic cables. The apparatus includes a tester having a transmitter and a receiver, wherein the transmitter provides at one end of a fiber optical cable a test signal of a known wavelength of light modulated at a known or signature AC frequency. The receiver detects the transmitted signal at a second end of the cable, determines the modulating frequency of the transmitted signal for identifying the transmitted wavelength of light and measures power of the AC signal. If measuring the power loss, the receiver further compares the power intensities of the transmitted signal with the power intensity of a stored reference for determining the power loss associated with the transmission of a known wavelength of light.
A tester for measuring the optical power attenuation of light signals having specific wavelengths and powers transmitted through a fiber optic cable, comprising:
