Bidirectional optical fiber transmission system |
摘要 |
There is disclosed a bidirectional optical fiber transmission system. This system includes first and second light transmitter-receiver sets and a single strand of optical fibers. The light transmitter-receiver sets each comprise (a) a light receiver, (b) a light transmitter whose light source is a light emitting diode, and (c) means to isolate downstream and upstream light from each other. The optical fibers connect the light-transmitter-receiver sets through the light isolating means. The emission spectra of the light emitting diodes at least partly overlap each other and the isolating means have wavelength pass bands which do not substantially overlap each other.
