Abstract
In this paper the channel capacity of a fiberoptic transmission system is estimated by upper and lower bounds. It is found that there is only a very small difference between these bounds so that the channel capacity is directly determined by them. The channel capacity is compared with the data rate of a binary transmission system with on-off-keying (OOK) of the optical power. A numerical example shows that the binary OOK-system achieves only about 20 - 25% of the channel capacity. This means that with improved transmission schemes the data rate of existing optical transmission systems can be increased dramatically. The only question left unanswered, is that of which modulation scheme does yield this improvement. It can be shown that a small improvement can be achieved using multilevel pulse amplitude modulation (PAM). For multilevel pulse position modulation (PPM), no improvement is obtained.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
