a plate disposed within the second end portion;
a potting material disposed within the second end portion;
a plurality of nozzles extending from the plate within the second end portion, wherein the potting material surrounds each of the plurality of nozzles; and
a retainer washer disposed within the main canister body.

2. The breakout canister of claim 1 , wherein the main canister body further comprises an intermediate portion disposed between the first end portion and the second end portion, wherein a first intermediate opening is defined between the first end portion and the intermediate portion, and wherein the retainer washer has a maximum outer width greater than a maximum width of the first intermediate opening.

3. The breakout canister of claim 1 , wherein the retainer washer is an internal tooth lock washer.

4. The breakout canister of claim 1 , wherein the retainer washer is a first retainer washer, and further comprising a second retainer washer disposed within the main canister body.

5. The breakout canister of claim 4 , wherein the second retainer washer is disposed within the second end portion.

6. The breakout canister of claim 4 , wherein the second retainer washer is a plurality of second retainer washers.

7. The breakout canister of claim 4 , wherein a maximum outer width of the second retainer washer is less than a maximum outer width of the first retainer washer.

8. The breakout canister of claim 1 , wherein the main canister body further comprises an intermediate portion disposed between the first end portion and the second end portion, the intermediate portion having a conical shape.

9. The breakout canister of claim 8 , wherein the retainer washer is disposed within the intermediate portion.

10. The breakout canister of claim 1 , wherein the second end portion includes an internal stop, the stop disposed at a predetermined distance from the second end opening, and wherein the plate engages the stop.

11. The breakout canister of claim 10 , further comprising a plurality of nozzles extending from the plate within the second end portion, and wherein a height of each of the plurality of nozzles is less than the predetermined distance.

12. The breakout canister of claim 10 , wherein a cushioning element is disposed between the plate and the stop.

13. The breakout canister of claim 1 , wherein the second end portion defines an internal groove, and further comprising a retainer member received partially within the groove.

14. The breakout canister of claim 13 , wherein the retainer member is a retainer key.

15. The breakout canister of claim 1 , wherein the first end portion includes an internal stop.

16. The breakout canister of claim 1 , further comprising a second potting material disposed within first end portion.

17. An optical fiber trunk cable breakout assembly, comprising:
a trunk cable, the trunk cable comprising an outer jacket and a plurality of subunits extending from the outer jacket; and
a breakout canister, comprising:
