Optical fiber connector with attenuation function

An optical fiber connector with attenuation function comprising:

• a connecting unit including a main housing and a connecting member that is disposed on said main housing, said main housing and said connecting member being arranged in a transverse direction;
• an adapter unit including an insertion seat that is connected removably to said main housing, and two guide frame bodies that are located respectively at two opposite sides of said insertion seat in said transverse direction, said insertion seat having two insertion holes that are spaced apart from each other in said transverse direction and that extend in a front-rear direction perpendicular to said transverse direction, each of said guide frame bodies extending in said front-rear direction away from said connecting unit and having a guide groove that extends in said front-rear direction, said guide grooves of said guide frame bodies facing each other;
• and
• an attenuation unit including two attenuation components that are arranged in said transverse direction and that are disposed within said main housing, two rear ferrules that are respectively connected to rear ends of said attenuation components, and that respectively extend rearwardly into said insertion holes, and two front ferrules that respectively connected to front ends of said attenuation components, and that respectively extend forwardly through and outwardly of said main housing;
• wherein said main housing of said connecting unit has two engaging open grooves that are formed respectively in opposite sides thereof in a lateral direction perpendicular to said transverse direction and said front-rear direction;
• and
• wherein said insertion seat of said adapter unit includes a seat portion formed with said insertion holes, and two engaging teeth protruding laterally and respectively from opposite sides of said seat portion and respectively engaging said engaging open grooves.
