We report both experimental and theoretical results for a physical implementation of a bipolar encoding scheme suitable for fiber optic networks. The power spectrum of an erbium-doped superfluorescent fiber source is encoded, the bipolar correlations of the codes are verified, and rejection of multiple-access interference is demonstrated in a fiber-based testbed. Simulations of the correlation process identify key optical parameters and physical characteristics important to the design of future systems.
