  • Patent number: 7637672
    Abstract: A pluggable optical transceiver includes a housing member comprising an extended portion to be plugged into a host device and an outer housing member to protrude out of the host device. An optical module mounted to the housing member can be coupled to an optical fiber. A circuit board is mounted to the housing member and electrically coupled to the optical module. The circuit board includes an electronic circuit and an electric interface configured to be electrically connected to the host device. The electric circuit is in thermal conductive communication with the extended portion to conduct heat from the electric circuit.

  • Patent number: 7493042
    Abstract: An optical communication system including a plurality of transceiver ports each including a transmitter configured to produce a downstream MLM-spectrum signal and a receiver configured to receive an upstream spectrum-sliced signal. The spectrum of the downstream MLM-spectrum signal comprises a plurality of distinct narrow-spectrum peaks each corresponding to a longitudinal mode.

  • Patent number: 7440701
    Abstract: An optical communication system includes a first wavelength filter, a bidirectional amplifier, and a second wavelength filter. The first wavelength filter can receive a downstream broad-spectrum signal and output a downstream spectrum-sliced signal in response to the downstream broad-spectrum signal. The bidirectional amplifier can amplify the downstream spectrum-sliced signal. The second wavelength filter can receive the amplified downstream spectrum-sliced signal from the bidirectional amplifier and route the amplified downstream spectrum-sliced signal. The second wavelength filter can also output an upstream spectrum-sliced signal in response to an upstream broad-spectrum signal. The bidirectional amplifier can amplify the upstream spectrum-sliced signal to product an amplified upstream spectrum-sliced signal that is subsequently routed by the first wavelength filter.
