Cable retention couplers and related methods

1. A retention assembly for coupling a cable comprising a plurality of optical fibers to a support, the retention assembly comprising:

a retention anchor configured to be coupled to a support, the retention anchor comprising:

a mounting plate configured to be coupled to a support, the mounting plate defining:

a first face;

a second face opposite the first face;

an entry hole extending through the mounting plate from the first face to the second face;

a latch hole; and

an engagement slot extending from a periphery of the entry hole; and

a retention coupler configured to be coupled to a cable comprising a plurality of optical fibers, the retention coupler comprising:

a retention support defining a first coupler face and a second coupler face opposite the first coupler face;

a retainer blade coupled to the first coupler face of the retention support via an extension;

an engagement surface associated with the second coupler face and configured to be adjacent a cable comprising a plurality of optical fibers, and

a latch member extending from the first coupler face and configured to engage the latch hole of the mounting plate,

wherein the retainer blade is configured to be passed through the entry hole, such that the extension extends through the entry hole from the first face to the second face of the mounting plate,

wherein the extension is configured to slide within the engagement slot of the mounting plate, such that the retainer blade is adjacent the second face of the mounting plate and the first coupler face of the retention support is adjacent the first face of the mounting plate,

wherein the latch member defines a lateral surface configured to engage an edge of the latch hole and prevent the extension from sliding out of the engagement slot once the latch member is received in the latch hole, and

wherein the retention support is configured to be flexed, such that the latch member is disengaged from the latch hole allowing the extension to slide within the engagement slot.

2. The retention assembly of claim 1 , wherein retainer blade comprises a catch element at an end of the extension remote from the first coupler face, the catch element being at least one of shaped or sized to pass through the entry hole and not through the engagement slot.

3. The retention assembly of claim 2 , wherein the retainer blade further comprises a stop element configured to engage an edge of the entry hole and prevent the extension from sliding farther into the engagement slot.

4. The retention assembly of claim 1 , wherein the engagement surface associated with the second coupler face comprises a plurality of ribs configured to prevent a cable from sliding relative to the engagement surface.

5. The retention assembly of claim 1 , wherein the retention coupler further comprises a projection extending from the second coupler face and having remote end coupled to the engagement surface, and wherein the projection defines a slot configured to receive a cable-tie for coupling a cable to the retention coupler.

6. The retention assembly of claim 5 , further comprising a cable-tie extending through the slot and configured to couple a cable to the retention coupler.

7. The retention assembly of claim 1 , wherein the retention coupler further comprises a grip element extending from the second coupler face opposite the latch member, and

wherein pulling or pivoting the grip element causes flexion of the retention support.
