摘要： In an example embodiment, a method includes receiving a first combined optical signal (209A) at an edge filter (250). The method further includes redirecting, at the edge filter (250), a second combined optical (209B) signal toward a first zigzag demultiplexer (210); and passing a third combined optical signal (209C) through the edge filter (250) toward a light redirector (230) based on wavelength. The method further includes redirecting the third combined optical signal (209C) toward a second zigzag demultiplexer (220). The method may further includes separating, at the first zigzag demultiplexer (210), the second combined optical signal (209A) into a first optical signal on a first optical path (201) and a second optical signal on a second optical path (202 based on wavelength. The method further includes separating, at the second zigzag demultiplexer, the third combined optical signal into a third optical signal on a third optical path (205) and a fourth optical signal on a fourth optical path (206) based on wavelengths.

摘要： An example embodiment includes a system for communicating an optical signal. The system includes an optical transmitter and an optical receiver. The optical transmitter includes one or more lasers configured to produce a light signal and a transmitter optical sub assembly (TOSA) receptacle. The TOSA receptacle optically couples the lasers to an optical fiber and launches a quasi-multimode optical signal (quasi-MM signal) that includes at least one lower order mode optical signal and at least one higher order mode optical signal onto the optical fiber. The optical receiver is connected to the optical fiber via a receiver optical sub assembly (ROSA) receptacle. The optical receiver is configured to receive the quasi-MM signal and to substantially block the at least one higher order mode optical signal.

摘要： 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.
