A rotary locking apparatus for locking and unlocking a fiber optic equipment tray and related methods are disclosed. The rotary locking apparatus may be a torsional rotary locking apparatus. The torsional rotary locking apparatus includes a rod having at least one protrusion and a torsion spring attached to the rod. The torsion spring may also be attached to a tray mount on the fiber optic equipment tray. The rod can be rotatably actuated such that the at least one protrusion selectively engages or disengages one or more of a plurality of slots in a tray guide to allow the fiber optic equipment tray to move from a closed to an open position. The torsion spring may be configured to lock the fiber optic equipment tray in either the open or the closed position when the at least one protrusion engages one of the plurality of slots in the tray guide.
1. A locking apparatus for a fiber optic apparatus, comprising: a rod having at least one protrusion configured to selectively engage one or more of a plurality of slots in a tray guide disposed on a chassis; anda torsion spring configured to attach to the rod and to a tray mounted on a fiber optic

The locking apparatus of claim 1, wherein the torsion spring is further configured to withstand a force when the fiber optic equipment tray is locked in the closed position such that fiber optic modules may be loaded from a rear of the chassis without the fiber optic equipment tray sliding forward. 10. The locking apparatus of claim 9, wherein the force is at least two (2) pounds. 11. The locking apparatus of claim 3, wherein the torsion spring is further configured to withstand a force when the fiber optic equipment tray is locked in the open position such that fiber optic modules may be loaded from a front of the chassis without the fiber optic equipment tray sliding backward. 12. The locking apparatus of claim 11, wherein the force is at least two (2) pounds. 13. The locking apparatus of claim 1, wherein at least two of the plurality of slots in the tray guide are spaced a fixed distance apart. 14. The locking apparatus of claim 13, wherein the fixed distance is between 3 and 4 inches. 15. A fiber optic apparatus, comprising: at least one tray guide disposed in a chassis having a plurality of slots and configured to receive at least one fiber optic equipment tray along a first direction, the at least one fiber optic equipment tray having at least one tray mount;a rod having a longitudinal axis parallel to the first direction and at least one protrusion, the at least one protrusion configured to selectively engage one or more of the plurality of slots in the at least one tray guide; anda torsion spring configured to attach to the rod and to the at least one tray mount on the at least one fiber optic equipment tray, wherein the torsion spring is further configured to lock the at least one fiber optic equipment tray in a closed position when the at least one protrusion engages a first one of the plurality of slots in the at least one tray guide. 16. The fiber optic apparatus of claim 15, wherein the rod is further configured to be rotatably actuated to allow the at least one protrusion to be disengaged from the first one of the plurality of slots such that the at least one fiber optic equipment tray is movable along the first direction within the at least one tray guide. 17. The fiber optic apparatus of claim 15, further comprising at least one module rail guide disposed on the at least one fiber optic equipment tray and configured to receive at least one fiber optic module from a rear of the chassis along the first direction. 18. The fiber optic apparatus of claim 17, wherein the at least one fiber optic equipment tray is locked in the closed position due to the at least one protrusion engaging the first one of the plurality of slots in the at least one tray guide. 19. The fiber optic apparatus of claim 15, wherein the torsion spring is further configured to lock the at least one fiber optic equipment tray in an open position when the at least one protrusion engages a second one of the plurality of slots in the at least one tray guide. 20. The fiber optic apparatus of claim 19, further comprising at least one module rail guide disposed on the at least one fiber optic equipment tray and configured to receive at least one fiber optic module from a front of the chassis along the first direction. 21. The fiber optic apparatus of claim 20, wherein the at least one fiber optic equipment tray is locked in the open position due to the at least one protrusion engaging the second one of the plurality of slots in the at least one tray guide. 22. A fiber optic apparatus, comprising: a plurality of tray guides disposed in a chassis, each of the plurality of tray guides having a plurality of slots and configured to receive a fiber optic equipment tray along a first direction;a plurality of fiber optic equipment trays, each of the plurality of fiber optic equipment trays comprising: a rod having a longitudinal axis parallel to the first direction and at least one protrusion, the at least one protrusion configured to selectively engage one or more of the plurality of slots of the tray guide;a torsion spring configured to attach to the rod and to at least one tray mount disposed on the fiber optic equipment tray, wherein the torsion spring is further configured to lock the fiber optic equipment tray in a closed position when the at least one protrusion engages a first one of the plurality of slots in the tray guide; andwherein the rod is further configured to be rotatably actuated to allow the at least one protrusion to be disengaged from the first one of the plurality of slots in the tray guide such that the fiber optic equipment tray is movable along the first direction within the at least one tray guide. 23.
