  • Patent number: 9608760
    Abstract: The present invention is an optical terminal device comprising a signal modulator configured to generate a first signal modulated onto a first optical sideband of a first optical wavelength signal and a second signal modulated onto a second sideband of the first optical wavelength signal, the first signal being a different type than the second signal; a receiver configured to receive a third signal modulated onto the first optical sideband of a second optical wavelength signal and a fourth signal modulated onto a second sideband of the second optical wavelength signal, the third signal being a different type than the fourth signal; and a circulator coupled to the signal modulator and the receiver, wherein the circulator is configured to communicate with a node of an integrated network via an optical fiber. A remote node, a communication terminal, and a method of performing integrated network access are also disclosed.

  • Patent number: 5506712
    Abstract: A photonic frequency routing type time division highway switch which requires no conflict control at the input side, and incorporates no inherent splitting loss of the optical signal power. The switch is formed by a plurality of tunable frequency convertors for allocating frequency channels to the optical signals on the input highways at each timeslot; a frequency router for connecting the optical signals outputted from the frequency convertors to its outputs according to the frequency channels allocated to the optical signals at each timeslot; and a plurality of frequency multiplexed output buffers for outputting the optical signals outputted from the frequency router to the output highways such that a plurality of optical signals with different frequency channels which are in an identical timeslot are outputted at different timeslots.
