Phase stabilized fiber-optic link for transmission and distribution of UHF and EHF reference signals

Abstract

Experimental investigation results on phase stabilized fiber-optic link for transmission and distribution of microwave (UHF) and millimeter wave (EHF) reference signals are considered. The link under investigation operates in the remote optical self-heterodyne mode and contains two wavelength tunable laser sources, lengthy fiber transversal filter and Er-doped fiber amplifier. The designed link provides, in the frequency regions stated, transmitted reference signals with less than 1/spl deg/ phase instability with full compensation of the insertion loss.
