Abstract
An optical-fiber connector includes an insulative main body having a pair of optical components extending forwardly therefrom. Each optical component defines at least one lens and a guiding post located at outside of the lens. Each guiding post defines a through hole extend through the guiding post and the main body in a front-to-back direction and fulfilled with the air for transmitting a test light. The test light from the through hole of the guiding post acts as an accurate measuring reference of the true position between the lens and the fiber because of having no displacement of the light path through a through hole.
Claims13
An optical-fiber connector, comprising:
- an insulative main body having a pair of optical components extending forwardly therefrom, each optical component defining at least one lens and a guiding post extending forwardly and located at outside of the lens;
- each guiding post defining a through hole extending through the guiding post and the main body in a front-to-back direction to service as a measure reference to test true position of the lens.
An optical-fiber connector, comprising:
- a main body defining receiving slots running through a rear face thereof for receiving fiber cables;
- a pair of lenses disposed at a front face of the main body in a first direction perpendicular to a front-to-back direction of the connector, the lenses being aligned with and couple with the fiber cables;
- a pair of guiding posts disposed at two sides of the pair of lenses along a first direction;
- a measuring reference means provided in the main body or the guiding posts which run through a front face and rear face of the connector and is filled with air.
A method of measuring true component positions in an optical module, comprising steps of:
- providing an insulative main body with two pairs of internal blind holes therein, said two pairs of blind holes being spaced from each other and symmetrically located by two sides of a center line of said main body;
- providing a pair of alignment posts on two opposite outer sides of said two pairs of internal blind holes along a transverse direction;
- and
- providing a passage extending through either the post or a centerline area of the main body in a front-to-back direction perpendicular to said transverse direction.
