Abstract
An optical transmission system is disclosed wherein a multiplexed analog signal is supplied to a laser diode to modulate the intensity of a long-wavelength laser beam. A single mode optical fiber transmission medium has a first inclined end face at a proximal end and a second inclined end face at a distal end. The laser beam is coupled to the proximal end of the transmission medium by a coupling means including a single mode optical fiber connecting medium having one end connected to the laser diode and an opposite end having a third inclined end face complementary to the first inclined end face and a coupler for coupling the first and third inclined end faces in abutment relation. An optoelectrical transducer having a light receiving face is located adjacent the distal end of the transmission medium, the light receiving face being parallel to the second inclined end face of the transmission medium to divert rays of light reflecting from the transducer away from the angle of reentry to the transmission medium.
