The multiplexor combines data received at the local interfaces into an outgoing data stream. The fiber optic modem transmits, at a first wavelength, the outgoing data stream to the fiber optic interface and receives, at a second wavelength, an incoming data stream via the fiber optic interface. The demultiplexor separates the incoming data stream into separate data streams, and forwards each of the separate data streams to its corresponding local interface."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fiber optic multiplex modem","description":"A fire alarm network fiber optic multiplex modem includes plural local interfaces, a fiber optic interface, a multiplexor, a fiber optic modem, and a demultiplexor.
