Samenvatting
Quadrature Amplitude Modulation (QAM) is considered to increase the channel capacity in bandwidth-limited large-core step-index polymer optical fiber links since it can take advantage of widely used low-cost QAM chips. The baseband in-phase and quadrature-phase signals of the QAM signal can be transmitted in two different wavelength channels with two low cost LEDs, at 460nm and 650nm respectively. In the computer simulation, the occupied bandwidth with this implementation decreased to 1/3, compared to the normal implementation of QAM. Using 16 QAM, 60Mbit/s over 100m 1mm core diameter step-index PMMA optical fiber has been realized. This system showed the feasibility of QAM transmission for low-cost high-speed transmission over large core plastic optical fibre. Using a 650nm red LED which combines the higher bandwidth and enough optical power, the transmission capacity can be increased further.
