Patent number: 10895691Abstract: This invention discloses highly scalable and modular automated optical cross connect switch devices which exhibit low loss and scalability to high port counts. In particular, a device for the programmable interconnection of large numbers of optical fibers (100s-1000s) is provided, whereby a two-dimensional array of fiber optic connections is mapped in an ordered and rule-based fashion into a one-dimensional array with tensioned fiber optic circuit elements tracing substantially straight lines there between. Fiber optic elements are terminated in a stacked arrangement of flexible fiber optic circuit elements with a capacity to retain excess fiber lengths while maintaining an adequate bend radius. The combination of these elements partitions the switch volume into multiple independent, non-interfering zones, which retain their independence for arbitrary and unlimited numbers of reconfigurations.Type: GrantFiled: August 2, 2018Date of Patent: January 19, 2021Assignee: TELESCENT INC.Inventor: Anthony Stephen Kewitsch
