Introduction
This high performance Analog RF Fiber Optic Transmission System converts RF
signals into intensity modulated light to be carried through standard single mode
optical fiber to the Optical Receiver. The Receiver converts the modulated light
back to the original RF signal. Fiber-Span uses high performance optical
components to ensure maximum dynamic range.
