Fiber optic cable slack management module
A fiber optic cable slack management module includes a base defining a first cable management spool, an outer face of which is configured to contact cables when cables are pulled away from the base and a second cable management spool, within which the first cable management spool is located. An inner face of the second cable management spool is configured to contact cables when cables are in a relaxed, non-pulled state. The fiber optic cable slack management module defines a cable exit adjacent the first cable management spool and defined at least partially by the inner face of the second cable management spool, the cable exit defined by a channel positioned between the first and second cable management spools.
1. A fiber optic cable slack management module comprising:
a base defining a first cable management spool, an outer face of which is configured to contact cables when cables are pulled away from the base;
a second cable management spool, within which the first cable management spool is located, wherein an inner face of the second cable management spool is configured to contact cables when cables are in a relaxed, non-pulled state, wherein the fiber optic cable slack management module defines a cable exit; and
at least one tray removably mounted to the base, the at least one tray configured for managing cables, wherein an outer peripheral wall of the at least one tray defines the second cable management spool, a cable entrance point for the at least one tray being adjacent the cable exit, wherein the first and second cable management spools are configured such that the cables are looped once around the at least one tray and the first cable management spool does not contact the cables when the cables are in the relaxed, non-pulled state and contacts the cables when the cables are pulled away from the base.
2. A fiber optic cable slack management module according to claim 1 , further comprising a plurality of removable trays mounted to the base in a stacked configuration, each of the trays configured for managing cables, wherein an outer peripheral wall of each tray defines the second cable management spool, wherein fibers entering the base along a common plane are directed to multiple different levels provided by the trays via ramps defined by the trays.
3. A fiber optic cable slack management module according to claim 2 , wherein the plurality of trays comprises two trays.
4. A fiber optic cable slack management module according to claim 1 , wherein an input for the cable slack management module is defined by a fiber optic fan-out.
5. A fiber optic cable slack management module according to claim 4 , wherein the input is defined at a rear of the base and the cable exit is defined at a front of the base, wherein the input and the cable exit are generally aligned when viewed in a front to back direction.
6. A fiber optic cable slack management module according to claim 2 , wherein each tray defines a smooth, flush ceiling so as to allow unobstructed movement of the cables between the relaxed, non-pulled state and a pulled state.
7. A fiber optic cable slack management module according to claim 6 , wherein each tray defines cable retention fingers extending inwardly from the outer peripheral wall, the retention fingers fitting within notches defined by a cover for each tray so as to define the smooth, flush ceiling.
8. A fiber optic cable slack management module according to claim 7 , wherein the cover for at least one of the trays is defined by a floor of an adjacent upper tray.
9. A fiber optic cable slack management module according to claim 1 , further comprising snap-fit features for removably mounting to a telecommunications fixture.
10. A fiber optic telecommunications system comprising:
a telecommunications chassis including a plurality of fiber optic adapters mounted to the chassis;
at least one cable slack management module mounted to the chassis, the cable slack management module configured to manage cables extending from fiber optic connectors coupled to the plurality of fiber optic adapters, the at least one cable slack management module comprising:
a base defining a first cable management spool, an outer face of which is configured to contact cables when cables are pulled away from the base;
a second cable management spool, within which the first cable management spool is located, wherein an inner face of the second cable management spool is configured to contact cables when cables are in a relaxed, non-pulled state, wherein the fiber optic cable slack management module defines a cable exit; and
at least one tray removably mounted to the base, the at least one tray configured for managing cables, wherein an outer peripheral wall of the at least one tray defines the second cable management spool, a cable entrance point for the at least one tray being adjacent the cable exit, wherein the first and second cable management spools are configured such that the cables are looped once around the at least one tray and the first cable management spool does not contact the cables when the cables are in the relaxed, non-pulled state and contacts the cables when the cables are pulled away from the base.
11. A fiber optic telecommunications system according to claim 10 , further comprising a plurality of the cable slack management modules mounted to the chassis in a stacked arrangement.
12. A fiber optic telecommunications system according to claim 10 , wherein the plurality of fiber optic adapters includes LC format fiber optic adapters.
13. A fiber optic telecommunications system according to claim 10 , wherein an input for the at least one cable slack management module is defined by a fiber optic fan-out that separates ribbonized fibers into individual cabled fibers leading to the fiber optic connectors coupled to the plurality of fiber optic adapters.
14. A fiber optic telecommunications system according to claim 10 , further comprising a plurality of removable trays mounted to the base in a stacked configuration, each of the trays configured for managing cables, wherein an outer peripheral wall of each tray defines the second cable management spool, wherein fibers entering the base along a common plane are directed to multiple different levels provided by the trays via ramps defined by the trays.
15. A fiber optic telecommunications system according claim 11 , wherein each cable slack management module includes two of the trays.
16. A fiber optic telecommunications system according to claim 14 , wherein each tray defines a smooth, flush ceiling so as to allow unobstructed movement of the cables between the relaxed, non-pulled state and a pulled state.
17. A fiber optic telecommunications system according to claim 16 , wherein each tray defines cable retention fingers extending inwardly from the outer peripheral wall, the retention fingers fitting within notches defined by a cover for each tray so as to define the smooth, flush ceiling.
