1. An optoelectronic device used with at least one optical fiber, the optoelectronic device comprising:
at least one transmitter disposed in the optoelectronic device and being configured to emit light;
a lens block disposed in the optoelectronic device adjacent the at least one transmitter;
an input on the lens block being configured to receive the light emitted from the at least one transmitter incident thereto;
a first section of a first reflective surface on the lens block being configured to reflect a first attenuated portion of the light;
a first output on the lens block being configured to output the first attenuated portion of the light to the at least one optical fiber;
a second section of the first reflective surface being configured to reflect a second attenuated portion of the light;
a second output on the lens block being configured to output the second attenuated portion of the light; and
at least one receiver disposed in the optoelectronic device adjacent the lens block and being configured to receive the second attenuated portion of the light propagated from the second output,
wherein the second output of the lens block comprises:
a second reflective surface opposing the first reflective surface, the second reflective surface being configured to reflect the second attenuated portion of the light; and
a refractive surface adjacent to a cavity being configured to refract the second attenuated portion of the light into the cavity to outside the lens block to the at least one receiver;
wherein:
the first reflective surface is disposed at an angled plane relative to the input and the first output;
the first section of the first reflective surface comprises first divisions of the first reflective surface disposed on the angled plane;
the second section of the first reflective surface comprises second divisions of the first reflective surface disposed at an angle from the angled plane; and
the first divisions and the second divisions are arranged in a checkered pattern across a portion of the first reflective surface.
