Abstract : Accordingly, one subject of the invention is to provide a fiber optic network system with low crosstalk between channels of the network by using spread spectrum and code-division multiplexing techniques. Another object of the invention is to provide a fiber optic ladder or star network system with low crosstalk between channels of the network by using spread spectrum and code-division multiplexing techniques. Another object of the invention is to provide an array of interferometric sensors using a fiber optic ladder or star configuration of interferometric fiber optic sensors and spread system and code-division multiplexing techniques to produce low crosstalk between sensors. A further object of the invention is to provide a fiber optic network system which utilizes spread spectrum and code-division multiplexing techniques to accomplish better suppression of unwanted signals with a shorter code sequence length
