Managing backreflection

An OSA comprising:

• a barrel;
• an optoelectronic transducer at least partially positioned within the barrel;
• a port defined by the barrel and configured to receive an optical fiber;
• an axis defined between a point on an optically active portion of the optoelectronic transducer and a point on a surface of the optical fiber;
• and
• a means for managing backreflection, the means serving to redirect an optical signal at least twice as the optical signal travels between the optoelectronic transducer and the port, wherein;
• for an optoelectronic transducer that comprises an optoelectronic transmitter, the means directs an optical signal generated by the optoelectronic transmitter along a path that converges with the axis at a predetermined location, and for a reflection of the transmitted optical signal traveling toward the optoelectronic transducer, the means directs the reflection along a path that diverges from the axis;
• and
• for an optoelectronic transducer that comprises an optoelectronic receiver, the means directs an optical signal received from a source external to the OSA along a path that converges with the axis at a predetermined location, and for a reflection of the received optical signal, the means directs the reflection of the received optical signal along a path that diverges from the optical axis.

An optoelectronic module comprising:

• a printed circuit board;
• a transmitter optical sub-assembly (TOSA) electrically connected to the printed circuit board;
• and
• a receiver optical sub-assembly (ROSA) electrically connected to the printed circuit board,
• wherein at least one of the TOSA or the ROSA comprises:
• a barrel;
• an optoelectronic transducer at least partially positioned within the barrel;
• a port defined by the barrel and configured to receive an optical fiber;
• an axis defined between a point on an optically active portion of the optoelectronic transducer and a point on a surface of the optical fiber;
• and
• an optical device positioned along the axis between the optoelectronic transducer and the port, the optical device comprising:
• a body at least a portion of which is formed from a material that is transmissible to light;
• a first surface of the body positioned at a first angle relative to a plane that is perpendicular to the axis;
• and
• a second surface of the body positioned at a second angle relative to the plane, wherein the first surface and the second surface are positioned at respective opposing ends of the body, and one or both of the first and second surfaces comprising:
• a first portion that is transmissible to light;
• and
• a second portion that is substantially non-transmissible to light.
