Paper Abstract

For short distance communications, graded index polymer optical fiber has been proposed as the physical transport layer for high data rate networks. This paper reports the results of various transmission experiments through polymer optical fiber. Bit-error-rate of < 10-9 has been obtained after transmission through 200 m of polymer optical fiber at received optical powers of -22 dBm at 155 Mb/s and -19 dBm at 622 Mb/s respectively. The experiment utilized a 659 nm laser as the source and a Si photodiode as a detector. The measured power penalty due to modal noise of < 1 dB is in agreement with the calculated results. The performance of a hybrid AM/BPSK optical fiber transmission system has been investigated. A BPSK modulated 2 Mb/s pseudorandom digital channel is substituted for one of the AM channels in a 60-channel cable TV system. For the subcarrier modulated digital channel, a bit error rate < 10-9 is obtained after transmission through 200 m of fiber. The intermodulation distortion (IMD) effects using long and short fiber lengths have been studied. The results show that distortion caused by the laser non-linearity did not degrade the system at low modulation depth. However, as the modulation depth of the BPSK signal is increased, the distortion is more pronounced. The differences in the measured IMD between the long and the short fiber is negligible, suggesting the fiber-induced distortion in the transmission system is small.
