1. A fiber connector plug, comprising:
a fiber comprising a fiber core, a reinforced layer wrapped around the fiber core, and an outer layer wrapped around the reinforced layer, wherein a part of the fiber core extends out of the reinforced layer, and wherein another part of the reinforced layer is not wrapped by the outer layer;
a ferrule fastened to a front end of the fiber, wherein the ferrule comprises a front end face away from the fiber;
a sleeve-shaped main housing sleeved over a periphery of the fiber, wherein the main housing comprises a sleeve-shaped main shaft, wherein the main shaft comprises a front end and a tail end that are opposite to each other, wherein the main shaft accommodates the fiber, wherein the tail end is fastened to the fiber, wherein the tail end is disposed with a through hole that penetrates an outer surface and inner surface of the main shaft, and wherein the through hole is configured to fill glue into a gap between the fiber and the inner surface of the main shaft, and wherein the glue is configured to fasten the reinforced layer to the main shaft;
a front cover fastened to one end of the main housing and encircling the ferrule, wherein the front end of the main shaft is connected to the front cover, wherein the front cover comprises a front end face that is away from the main housing and a rear end face that faces the main housing, wherein the front end face of the ferrule is flush with the front end face of the front cover, or in an axial direction the front end face of the ferrule is located between the front end face of the front cover and the rear end face of the front cover; and
a slot formed between the front cover and the ferrule,
wherein the slot is configured to accommodate a ferrule sleeve of a fiber adapter, such that an end face of the ferrule sleeve is located in the slot, and
wherein the ferrule is configured to be inserted into the ferrule sleeve.
