PROBLEM TO BE SOLVED: To provide a reception unit for optical fiber links, a unit capable of separating optical signals in a visible region and optical signals in an infrared region that are simultaneously transmitted through an optical fiber and converting to electric signals, in a reception unit for use in optical fiber links which perform multiplex communication by simultaneously transmitting through an optical fiber a plurality of optical signals having a different wavelength from each other, and also to provide electronic equipment and an optical fiber link system using this unit. SOLUTION: The reception unit 36 for optical fiber links includes: a photo diode PD1 for receiving optical signals of infrared wavelengths and converting to electric signals; photo diodes PD2, PD3, PD4 for receiving optical signals of visible wavelengths and converting to electric signals; an interference filter 25 arranged on the light receiving face 20 of the photo diode PD1 to transmit only the near infrared light; and an interference filter 26 arranged on the light receiving faces 21-24 of the photo diodes PD2, PD3, PD4 to transmit only the visible light.
