Patent ID: 6856719

Claim:
An optical switch system comprising: N first type switch modules each including: M dual fiber input collimators; M dual fiber output collimators; and a switching device moveably positioned between said input collimators and said output collimators, said switching device configured to provide M signal paths for optionally switching signals coming said M input collimators toward said M output collimators; M input fibers respectively bringing signals in and connected to the corresponding input collimators of at least one of said first type switch modules; M output fibers respectively taking signals out and connected to the corresponding output collimators of at least one of said first type switch modules; said input collimators of each of said first type switch modules cascading the corresponding input collimators of another of said first type switch modules; and said output collimators of each of said first type switch modules cascading the corresponding output collimators of another of said first type switch modules; wherein M and N are integers, and said signals coming from the input fibers leaves from the output fibers under a condition that N channels of said signals in the M input fibers have been selectively switched by said N first type switch modules.
