Pulse of light indicates a 1-bit and absence 0-bit
Pulse of light indicates a 1-bit and absence 0-bit
Detector generates electrical pulse when light falls on it
Refraction traps light inside the fiber
Fibers can terminate in connectors, be spliced mechanically, or be fused to form a solid connection
LEDs and semiconductor lasers can be used as sources
Tapping fiber is complex ? topologies such as rings or passive stars are used
