Multi-wavelength light emitting and receiving apparatus for monitoring connections by optical fibers

摘要: A multi-wavelength light emitting and receiving apparatus for monitoring connections by optical fibers comprising a case, an emission section, reception keyboard selecting operating modes measurement scales, display arrangement, processing unit including microprocessor connected to the feed. The sections are mounted in drawer provided with connector that can be inserted into complementary this latter containing keyboard, unit, It also contains at least one more emitting/receiving equipped said of case another controlled current source, light-emitting diode having wave-length different from first other photoreceiver spectral window covering amplifier outlet photoreceiver. Each has gain adapted response associated wavelength emitted situated corresponding drawer, such identical levels powers respectively diodes received photoreceivers amplifiers deliver output signals same levels.
