The invention relates to the telecommunication industry, in particular, to milimeter-wave analog radio signal transmission over optical fiber (AROF) in the wavelenght division multiplexed (WDM) passive optical access systems (PON). Offered the hybrid AROF-WDM-PON fiber optical system, using the multi-level pulse amplitude modulation (M-PAM), in parallel to broadband internet data transmission, can provide transmission of millimeter-wave radio frequency range signal via existing, for 5G mobile communication, fiber optical distribution network.
