ABSTRACT:
Optical triplexers are disclosed. The optical triplexers include an optical fiber, a first ball lens optically coupling a first optical signal between a first opto-electronic device and a first wavelength selective filter, and a second ball lens optically coupling a second optical signal between a second opto-electronic device and the first wavelength selective filter. The optical triplexers further include a second wavelength selective filter optically coupling the first and second optical signals between the first wavelength selective filter and a third ball lens and a fourth ball lens optically coupling a third optical signal between a third optical signal between a third opto-electronic device and the second frequency selective filter. The second wavelength selective filter optical couples the third optical signal between the fourth ball lens and the third ball lens. Thus, each of the optical signals are selectively coupled between one of the opto-electronic devices and the optical fiber.
