A fiber optic telecommunications device includes a rack for mounting a plurality of chassis, each chassis including a plurality of trays slidably mounted thereon and arranged in a vertically stacked arrangement. Each tray includes fiber optic connection locations and a cable manager coupled to the tray and also coupled to the chassis, the cable manager for routing cables to and from the fiber optic connection locations and defining a plurality of link arms pivotally connected such that the manager retracts and extends with a corresponding movement of the tray, wherein the link arms pivot relative to each other to prevent cables managed therein from being bent in an arc having a radius of curvature less than a predetermined value, each link arm defining a top wall, a bottom wall, and two oppositely positioned sidewalls, each link arm defining an open portion along at least one of the sidewalls and an open portion along the top wall for receiving cables therein, the open portions along the top wall and the at least one of the sidewalls communicating with each other.

1. A fiber optic telecommunications device comprising: a telecommunications chassis including: at least one fiber optic tray slidably mounted to the chassis, the at least one fiber optic tray slidable between a closed storage position and an open access position, the at least one fiber optic tray including:fiber optic connection locations for connecting cables; anda cable manager coupled at a first end to the fiber optic tray and coupled at a second end to the telecommunications chassis, the cable manager configured for routing cables to and from the fiber optic connection locations, the cable manager defining a plurality of link arms that are pivotally connected to each other such that the cable manager retracts and extends with a corresponding movement of the tray as the link arms pivot with respect to each other, wherein the link arms are configured to pivot relative to each other to prevent fiber optic cables managed therein from being bent in an arc having a radius of curvature that is less than a predetermined value during the movement of the tray, wherein at least two of the pivotally connected link arms include a compression spring therebetween to bias the link arms away from each other. 2. A fiber optic telecommunications device according to claim 1, wherein the chassis includes three slidable fiber optic trays arranged in a vertically stacked arrangement, each chassis sized and shaped to occupy a 1RU of standard telecommunications rack space. 3. A fiber optic telecommunications device according to claim 2, wherein the chassis includes three slidable fiber optic trays arranged in a vertically stacked arrangement on a right side of the chassis and three slidable fiber optic trays arranged in a vertically stacked arrangement on a left side of the chassis, each chassis sized and shaped to occupy a 1RU of standard telecommunications rack space. 4. A fiber optic telecommunications device according to claim 1, wherein the chassis includes twelve slidable fiber optic trays arranged in a vertically stacked arrangement, each chassis sized and shaped to occupy a 4RU of standard telecommunications rack space. 5. A fiber optic telecommunications device according to claim 4, wherein the chassis includes twelve slidable fiber optic trays arranged in a vertically stacked arrangement on a right side of the chassis and twelve slidable fiber optic trays arranged in a vertically stacked arrangement on a left side of the chassis, each chassis sized and shaped to occupy a 4RU of standard telecommunications rack space. 6. A fiber optic telecommunications device according to claim 1, wherein the connection locations are defined by fiber optic adapters. 7. A fiber optic telecommunications device according to claim 6, wherein each adapter includes electrical contacts that are configured to make an electrical connection with a fiber optic connector inserted into the adapter, the electrical contacts communicating with a controller mounted on the chassis. 8. A fiber optic telecommunications device according to claim 6, wherein the fiber optic adapters are mounted to the at least one tray with a snap-fit interlock. 9. A fiber optic telecommunications device according to claim 6, wherein the fiber optic adapters are LC-format adapters. 10. A fiber optic telecommunications device according to claim 1, wherein the cable manager includes five link arms that are pivotally connected to each other. 11. A fiber optic telecommunications device according to claim 1, wherein the at least one fiber optic tray is removable from the telecommunications chassis via a flexible lever. 12. A fiber optic telecommunications device according to claim 1, wherein each tray is mounted on the chassis via a slide assembly that includes a gear mechanism. 13. A fiber optic telecommunications device according to claim 12, wherein the slide assembly houses a flexible printed circuit board that flexes as the tray moves back and forth, the flexible printed circuit board configured to relay information from the fiber optic connection locations on the tray to other parts of the chassis. 14. A fiber optic telecommunications device according to claim 13, wherein the flexible printed circuit board relays information from the fiber optic connection locations on the tray to a central printed circuit board of the chassis, wherein the connection from the flexible printed circuit board to the central printed circuit board is made through a micro printed circuit board that is removably mounted within the slide assembly. 15. A fiber optic telecommunications device according to claim 14, wherein the micro printed circuit board includes at least one light-emitting diode to identify a particular tray. 16. A fiber optic telecommunications device according to claim 1, wherein the link arms are pivotally coupled with respect to each other so as to define a limited pivotal movement therebetween, wherein at least some of the link arms include snap-fit coupling features defined by cylindrical tabs on a first male end and cylindrical receptacles on an opposite second female end for providing the pivotal movement therebetween. 17. A fiber optic telecommunications device according to claim 1, wherein the chassis includes at least one pivot door with a spring-loaded latching mechanism for allowing and limiting access to the at least one fiber optic tray slidably mounted on the chassis.
