Development of Optical Subassembly for Plastic Optical Fiber in High Speed Applications

A low cost optical sub-assembly design for large core fiber is presented. The full module is realized by assembling the low cost optical sub-assembly directly on the functional PCB. -7dBm optical power output and 6 dB extinction ratio are achieved at transmitter by the vertical self-alignment and horizontal passive alignment. 190 m link distance is achieved at 2.5 Gbps and 340 m link distance is achieved at 1.25 Gbps for the transmitter with grade index plastic optical fiber.
