We have developed a novel fiber sensor array telemetry that uses multiple all-fiber, all-optical switches for time domain multiplexing. Incorporating optical switches improves the telemetry by connecting only one sensor at a time to the buses and thu

We report on optimizing the signal-to-noise ratio (SNR) of large-scale fiber sensor arrays employing erbium-doped fiber amplifier (EDFA) telemetry with respect to the number of sensors per rung, the number of amplifiers per array, and the coupling ra

For part I see, ibid., p. 218, 1998. We discuss how to minimize the pump power required for large-scale fiber sensor arrays employing erbium-doped fiber amplifier (EDFA) telemetry with respect to the number of amplifiers per bus, number of sensors pe

We examine the signal-to-noise ratio (SNR) performance of a novel type of time domain multiplexed sensor arrays in which low gain (1-10 dB) fiber amplifiers are incorporated to compensate for splitting losses between sensors. The system noise figure

We report what we believe to be the first laboratory prototype of a fiber sensor array using multiple low-gain (5dB) remotely pumped amplifiers in a 10-rung ladder structure. Incorporating amplifiers improves the system noise figure to less than 20dB

We report what are believed to be the first measurements of the phase sensitivity of a fiber sensor array using multiple low-gain remotely pumped amplifiers with an interferometric sensor inserted. The measured phase sensitivities for individual rung

The acoustic fiber sensor arrays that have been developed over the past two decades for oil exploration and other applications can support hundreds of fiber hydrophones per fiber pair and exhibit exceptional properties, including shot-noise-limited s

Many applications require using common input and output fibers to support a large number of interferometric fiber sensors located far from the receiving electronics. Passive multiplexing of sensors is limited by splitting and dissipative losses to ap
