Abstract

A wavelength-division-multiplexed (WDM) optical interface has been proposed and demonstrated with the capacity of adding and dropping wavelength interleaved fiber-radio WDM channels spaced at 25 GHz and also enabling wavelength reuse, which eliminates the need for a light source at the base station. The proposed WDM optical interface is realized by the use of a multiport optical circulator in conjunction with multinotch fiber Bragg grating (FBG) filters. Its functionality is demonstrated both by experiment and simulation. The effects of optical impairments on the transmission performance of WDM channels were studied in detail through simulation for single and cascaded configurations of the interface.
