  • Single fiber optical communication system
    Patent number: 4736359
    Abstract: A single fiber optical communication system (SFOCS) allows, in many operational scenarios, one-person deployment and recovery of optical links. Wavelength division multiplexing (WDM) is employed to provide full-duplex, bi-directional transmission. An optical subsystem achieves the wavelength multiplexing and demultiplexing while at the same time allowing for an unpolarized terminal design. Selection by the system of the WDM operating wavelengths between a pair of SFOCS terminals is performed without operator intervention.
