A communication socket comprises a housing including a base portion having a bottom wall and a plurality of sidewalls and a cover portion. The base portion and the cover portion are detachably engaged with each other. The base portion includes a plurality of knock-off holes for inserting an optical fiber at different positions in the sidewall and/or a plurality of fiber entries for inserting a fiber through the bottom wall. The fiber-connector-mounting portion extends from the base. Each of the fiber-connector-mounting portion includes a spacer for maintaining a fiber connector at a distance away from the bottom wall, and a space for inserting the fiber between the fiber connector and the bottom wall. The volume of the communication socket can be minimized, the integration thereof can be improved, the fiber can enter the communication socket in all directions while the fiber's bend radius is satisfied, and the management on the fiber and cable in the communication socket is effective.
