Fiber optic beam splitter

A fiber optic beam splitter comprising:

• a housing;
• a single first optical fiber;
• a pair of second optical fibers which meet and abut the single first optical fiber at a location within the housing, the housing overmolded over the single first optical fiber and the pair of second optical fibers;
• and
• an optical adhesive at the location where the pair of second optical fibers meet and abut the single first optical fiber.

An optical communication module comprising:

• first and second fiber optic beam splitters, each beam splitter comprising a housing, a single first optical fiber and a pair of second optical fibers which meet and abut the single first optical fiber at a location within the housing, the housing overmolded over the single first optical fiber and the pair of second optical fibers;
• a first light emitting diode (LED) and a first photodiode connected to the first fiber optic beam splitter;
• a second light emitting diode (LED) and a second photodiode connected to the second fiber optic beam splitter;
• wherein for the first beam splitter:
• a tip of a first of the pair of second optical fibers is connected outside of the housing to the first LED;
• a tip of a second of the pair of second optical fibers is connected outside of the housing to the first photodiode;
• and
• a tip of the single first optical fiber, which tip is outside of the housing, is in optical communication with an exterior of the module;
• wherein for the second beam splitter:
• a tip of a first of the pair of second optical fibers is connected outside of the housing to the second LED;
• a tip of a second of the pair of second optical fibers is connected outside of the housing to the second photodiode;
• and
• a tip of the single first optical fiber, which tip is outside of the housing, is in optical communication with an exterior of the module.
