Novel single-fiber bidirectional optical add-drop multiplexer for optical distribution networks

A novel single-fiber bi-directional optical add-drop multiplexer is proposed for wavelength division multiplexing distribution networks. It includes only two optical circulators and two sets of fiber Bragg grating, with advantages of passive, low insertion loss and cost- effective. Self-healing function can be provided passively to the distribution ring network with only one fiber. Very small degradation of bit-error-rate (power penalty < 0.1 dB) is observed when it is used for bi-directional add-drop and transmission.
