A prototypical fiber system Persans – 1/31/02
Elements of a communications system • signal source • transceiver (light source + modulator) • multiplexer • optical fiber • amplifier • optical fiber • demultiplexer • transceiver (receiver) • electronics Persans – 1/31/02
Limits of the capability of fibers • mode dispersion • material dispersion • waveguide dispersion Persans – 1/31/02
Fundamental limits of fibers: attentuation Persans – 1/31/02
Fundamental Limits • Limit on the amount of power we can put into one end of a fiber (non-linear loss) • Limits on the separation of two digital bits from one another (dispersion) • Limits on the loss in a fiber with distance • Limits on the detection of a signal from a background.
