  • Patent number: 9143236
    Abstract: The present invention is an apparatus and method that identifies and localizes fiber breaks or faults automatically, utilizing a fiber optic data transceiver that has ?OTDR functionality. The transceiver of the present invention is a single wavelength bi-directional transceiver that during normal operation sends and receives optical data streams in the same wavelength window using any protocol and reports the distance to the fault or multiple faults nearly instantaneously when the transfer of data is disrupted, without the need to have fiber lines dedicated for this purpose or physically connect and reconnect each fiber line to check for faults and eliminates the need to map out the distance to the remote transceiver.

  • Publication number: 20050201761
    Abstract: A fiber optic transceiver adapted for use in an optical fiber data transmission system is capable of detecting reflection problems in fiber optic links and providing information related to the distance to the point of reflection. The fiber optic transceiver contains a fiber interface, a receiver, a transmitter, and a microcontroller. The microcontroller controls the transmitter to modulate the laser power to transmit impulse test data and the transceiver includes circuitry and microcode to detect reflection due to fiber connection problems. This enables trouble shooting during installation and/or reconfiguring the connection automatically, in response to a connection problem, and provides a physical layer link.

  • Patent number: 6606430
    Abstract: A passive optical network which is capable of full duplex digital transmission at high data rates and which also provides analog broadcast transmission is disclosed. A central station provides analog broadcast transmission at a first wavelength of light and full duplex digital transmission using second and third wavelengths of light. Optical networking units, electrically or wirelessly coupled to end users in the network, are optically coupled to the central station via passive optical network nodes. The optical networking units resolve the two broadcast streams from the central station employing compact optics configured on a transparent substrate and provide burst mode digital transmission up stream to the central station on a time division multiple access basis.

  • Publication number: 20020054409
    Abstract: An optical transceiver adapted for use in an optical fiber data transmission system which is capable of efficiently detecting burst mode data transmission from multiple transmitters despite phase differences between data bursts is disclosed. The transceiver operating in a receive mode employs a front end which receives modulated light signals and converts the signals to modulated electrical signals and provides a digital signal. A back end, coupled to the front end, receives the digital signal and a clock signal and outputs data derived from the digital signal and phase aligned to the clock. The back end comprises a clock and data phase aligning circuit which derives plural phase shifted digital signals from the input digital signal and selects one of the phase shifted digital signals as an output. This provides output data which is phase aligned to the clock. High speed phase alignment is provided allowing accurate phase alignment on a burst to burst basis.

  • Publication number: 20020027688
    Abstract: A fiber optic transmitter and/or transceiver adapted for use in an optical fiber data transmission system which is capable of transmitting data at high data rates in burst mode is disclosed. A digital automatic power control circuit stores digital values for modulation and bias laser driver control. These values compensate for variations in laser power due to temperature variations or other factors and are reestablished on a burst by burst basis. The present invention further provides an optical transmitter or transceiver which can provide such capability without added cost or complexity. The optical transmitter or transceiver is further capable of operating in both burst and continuous modes.

  • Publication number: 20020027690
    Abstract: A fiber optic transmitter and/or transceiver adapted for use in an optical fiber data transmission system which is capable of transmitting data at high data rates in burst mode is disclosed. An analog dual loop automatic power control circuit samples monitored laser power peak and valley levels and uses them for modulation and bias laser driver control. These levels compensate for variations in laser power due to temperature variations or other factors. The sampled peak and valley levels are held between bursts in an analog level memory and are reestablished on a burst by burst basis. The optical transmitter or transceiver is further capable of operating in both burst and continuous modes.
