摘要： High-resolution optical backscatter system and method to discover the end-to-end physical topology of complex, interconnected fiber optic network, and to automatically monitor and troubleshoot its performance. Each passive cable element has unique, substantially unchanging optical backscatter signature based on microscopic random imperfections of the glass core along the length of the optical fiber, measurable along the length of the optical fiber using an optical reflection meter. The resulting signature is a two dimensional array of data points (or trace) corresponding to the optical backreflection signal strength as a function of length. When multiple cables are interconnected to produce a link, the corresponding traces of the multiple cables are concatenated to produce a composite trace for the entire link. The composite trace is compared to the traces of individual cables and the series of cables comprising the link and the serial relationship in which they are interconnected is thereby determined.

摘要： Apparatus and methods are employed to install fiber optic cables in a data center facility using one or more cable dispensing robots that dispense fiber optic cable that is pre-spooled on a cable cartridge, by programmatically unspooling the cable from the cable cartridge and paying the cable out along a potentially transverse oscillatory path (e.g. sinusoidal curve) as the robot moves down a cable tray network that is arranged adjacent and above large numbers of equipment bays. A controller accesses a database which stores the state of the cables within the cable tray network. The database further stores information regarding availability of cable cartridges of standard cable lengths, which are potentially stored within a cable cassette loading/unloading system. The controller receives instructions on where and how to spatially deploy a fiber optic interconnect cable within the tray network of the data center facility.

摘要： Systems and methods to incrementally scale robotic software-defined cross-connects from 100 to more than 100,000 ports are disclosed. A system is comprised of individual cross-connect units that individually scale in increments of say, 96 interconnects in tier 1 to, for example, 1,008 interconnects total. A system comprised of multiple cross-connect units arranged and interconnected in a two-tier approach is disclosed, one which achieves fully non-blocking, any-to-any connectivity with the flexibility to grow incrementally. Methods to build out this system over time, in an incremental and non-service interrupting fashion, are described.

摘要： A highly scalable and modular automated optical cross connect switch devices which exhibit low loss and scalability to high port counts. 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. The separation into spaced-apart zones provides clearance for one or more robotic actuators to enter the free volume substantially adjacent to the two-dimensional array of connectors and mechanically reconfigure connectors without interrupting other circuits.

摘要： This invention discloses patch-panel systems for organized configuration management of large numbers of fiber optic interconnection strands, wherein each strand transmits high bandwidth signals between devices. In particular, a system for the programmable interconnection of large numbers of optical fiber strands is provided, whereby strands connecting a two-dimensional array of connectors are mapped in an ordered and rule based fashion into a one-dimensional array with substantially straight lines strands there between. The braid of fiber optic strands is partitioned into multiple independent, non-interfering zones or subbraids. The separation into subbraids provides spatial clearance for one or more robotic grippers to enter the free volume substantially adjacent to the two-dimensional array of connectors and to mechanically reconfigure one or more optical fiber strands without interrupting or entangling other fiber optic strands.

摘要： An automated, robotic patch-panel system in a highly compact form factor implementing Knots and Braids switching algorithms is disclosed. This system incorporates stacked layers of connector ports, each row of connector ports defining an arc with a radius of curvature, wherein the radius of curvature is substantially larger than the total height of the stacked layers. A synchronized gripper pair on a three axis actuation system is used to disconnect, weave and connect fibers arbitrarily across an array of dense connector ports on a curvilinear surface. Each row of connector ports is independently translatable by slight rotation to generate the proper relationship between surrounding fibers and the individual fiber undergoing the multi-step reconfiguration process.
