Abstract

Experimental measurements have been carried out on 62.5/12- and 50/125-μm multimode fiber links using 850-nm vertical-cavity surface-emitting lasers transmitters for their coherence bandwidth, a parameter commonly used for wireless systems. It is shown that characterization using the coherence bandwidth over any given signal band provides reliable indications of the performance of radio over fiber systems for the transmission of different wireless radio signals (GSM, UMTS, WLAN) without the need to test using modulated signals.
