Disclosed herein is an angular optical component retention and removal system that reduces the amount of space needed to accommodate fiber optic cables and enables optical components to be quickly and easily inserted, retained, and removed from an optical communications system. The optical component retention and removal system may include a single or plural angular retention sections that retain optical components in an angular orientation through a faceplate. The system may further include an insertion / retention mechanism that enables an optical component to be inserted and removed with a single hand. With the system, fiber optic cables extend at an angle from the optical components, requiring less clearance space in front of the faceplate for provision of the fiber optic cables.
