We report on the construction and performance of an eight-element time-division multiplexed fiber-optic sensor array. The array, which is based on a transmissive tapped-serial architecture recently developed at our laboratory, utilizes low-coupling-ratio fiber couplers (-1%) to couple light from each sensor element to an output fiber 'bus'. The network exhibits intrinsic optical crosstalk effects which have been fully characterized and compared to theoretical models. Crosstalk figures in the range -25 to -45 dB were experimentally observed, in good agreement with predicted levels of ~-27 to -40 dB.
