1. A fiber optic assembly comprising:
a housing having an exterior and an internal volume;
a cable port configured for a plurality of fiber optic cables to pass from the exterior of the housing to the internal volume of the housing; and
a cable strain relief comprising:
a base;
a restraint projection extending from the base so as to be located within the internal volume of the housing, wherein the restraint projection comprises a first face and an opposing second face, a leading edge facing the internal volume, and a trailing edge facing the exterior of the housing; and
an arm extending from the base, wherein the arm is configured to extend through the cable port to the exterior of the housing,
wherein the restraint projection is configured to receive the plurality of fiber optic cables banded at a first location and the arm is configured to receive the plurality of fiber optic cables banded at a second location, the first location disposed at the leading edge and the second location disposed proximate to the trailing edge, such that a first portion of the plurality of fiber optic cables is disposed at the first face and a second portion of the plurality of fiber optic cables is disposed at the second face, and the restraint projection resists lateral movement of the plurality of fiber optic cables relative to the base.
