Telecommunications module
A telecommunications module defines an interior with separate right and left chambers. An optical component is housed within the left chamber. Signal input and output locations are exposed to the right chamber. The right chamber allows excess fiber to accumulate without bending in a radius smaller than a minimum bend radius. A dual-layered cable management structure is positioned within the right chamber that defines a lower cable-wrapping level and a separate upper cable-wrapping level. The upper cable-wrapping level is defined by a removable cable retainer mounted on a spool defining the lower-cable wrapping level. Cabling carrying the input and output signals are passed between the right and left chambers before and after being processed by the optical component.
1. A telecommunications module comprising:
a housing including a main housing portion defining an interior formed by a first sidewall, a second sidewall, a bottom wall, a front wall, and a rear wall;
the interior defining a first chamber separated from a second chamber;
a fiber optic component housed within the second chamber;
a signal input location for receiving an input signal to be processed by the fiber optic component and a signal output location for exiting an output signal processed by the fiber optic component, wherein at least one of the signal input location and the signal output location is defined by the front wall, wherein a cable carrying the input signal is fixed adjacent the signal input location via a crimp assembly that allows an internal fiber of the cable carrying the input signal to move through a wall of the main housing portion, and a cable carrying the output signal is fixed adjacent the signal output location via a crimp assembly that allows an internal fiber of the cable carrying output signal to move through a wall of the main housing portion, wherein an excess fiber length formed when an outer jacket of the cables contracts more than the fiber therewithin due to temperature variations is accommodated by the first chamber to allow the excess fiber length to accumulate without bending in a radius smaller than a minimum bend radius; and
a cable management structure positioned within the first chamber, the cable management structure including both the cable carrying the input signal and the cable carrying the output signal wrapped therearound for cable management;
wherein the cable carrying the input signal and the cable carrying the output signal are passed between the first chamber and the second chamber before and after being processed by the fiber optic component, respectively.
2. A telecommunications module according to claim 1 , wherein the fiber optic component is a fiber optic splitter.
3. A telecommunications module according to claim 2 , further comprising a splice location adjacent the fiber optic splitter within the second chamber.
4. A telecommunications module according to claim 2 , further comprising a plurality of cables carrying output signals that have been split from the input signal by the fiber optic splitter.
5. A telecommunications module according to claim 4 , wherein each of the plurality of cables carrying output signals are fixed adjacent the signal output location via crimp assemblies.
6. A telecommunications module according to claim 1 , wherein the signal input location is defined by a selectively-exposable opening at the front wall.
7. A telecommunications module according to claim 6 , wherein the housing further includes a removable cover mounted to the main housing portion to define a top wall, wherein the cover defines a protrusion extending toward the main housing portion, the protrusion received within the selectively-exposable opening defined on the front wall of the main housing portion when the cover is mounted on the main housing portion, the protrusion of the cover being selectively breakable to expose the opening defined on the front wall of the main housing portion for use as the signal input location.
8. A telecommunications module according to claim 6 , wherein the signal input location is defined by at least two selectively-exposable openings at the front wall.
9. A telecommunications module according to claim 1 , further comprising an insect-infestation prevention device mounted at the signal output location, the insect-infestation prevention device defining a unitary body with a top end, a bottom end, a front end, a rear end, a right side, and a left side, the unitary body configured as an insert piece for at least partially covering an opening defining the signal output location of the module, the insect-infestation prevention device further defining a plurality of partial cutouts extending generally from the top end toward the bottom end of the body, the cutouts configured to receive cables, each of the cutouts defining a zig-zag configuration for increasing the density of cables that can be stacked within the cutouts in a direction extending from the top end toward the bottom end, and opposing mounting flanges on the right and left sides of the body, respectively.
10. A telecommunications module according to claim 1 , wherein the main housing portion defines a divider wall separating the first chamber from the second chamber, the divider wall defining a notch for allowing passage of cables between the first and second chambers.
11. A telecommunications module according to claim 1 , wherein the module is configured to be mounted to a telecommunications tray with a snap-fit interlock.
12. A telecommunications module according to claim 1 , further comprising a bend limiting boot positioned at the signal output location extending forwardly from the front wall of the main housing portion.
13. A telecommunications module according to claim 1 , further comprising a bend limiting boot positioned at the signal input location extending forwardly from the front wall of the main housing portion.
