Patent ID: 7008120

Claim:
An apparatus comprising: a substrate on which a light emitter and a light detector are mounted; a first optical module adapted to optically couple light received from a first optical cable to the light detector, said first optical module including a first lens to collimate light received from the first optical cable and a second lens optically coupled to the first lens to focus received collimated light onto the light detector, said first optical module including a head portion; a second optical module adapted to optically couple light produced by the light emitter to a second optical cable, said second optical module including a first lens to collimate light received from the light emitter and a second lens optically coupled to the first lens to direct light into the second optical cable, said second optical module including a head portion; wherein each of the first and second optical modules comprise a single piece polymer structure; a standoff fixedly mounted to the substrate, said standoff including two recesses defined therein, each said recess to engage the head portion of a respective optical module wherein at least one gap is formed between the head portion of each optical module and the respective recess, said gap to allow active alignment of an optical module wherein the optical module is positioned within the respective recess such that a maximum amount of light is optically coupled; and epoxy disposed in said gap for fixedly securing the head portion of an optical module to a respective recess upon completion of said active alignment.
