  • Patent number: 7218859
    Abstract: Techniques and systems for monitoring of optical signals are described. Each of a plurality of optical signals is supplied to an optical port. A port signal is generated based on each of the optical signals and each of the port signals is subjected to a time delay to create a time delayed signal, with a different time delay being present in each of the time delayed signals. The time delayed signals are multiplexed to create a multiplexed signal comprising a plurality of multiplexed signal components, each component corresponding to one of the time delayed signals and exhibiting a time delay characterizing the corresponding time delayed signal. A desired one or ones of the multiplexed signal components are selected by analysis or display by specifying a time delay present in the time delayed signal represented by the desired component, and selecting a signal component exhibiting the specified time delay.

  • Patent number: 7000863
    Abstract: A reel for storing optical fiber is disclosed that significantly reduces the torsional force applied to optical fiber as the fiber is being wound onto the reel for storage. The optical fiber reel comprises two spindles that are offset with respect to the rotational center of the reel. Such an arrangement causes the fiber to be wound onto the reel in a substantially linear fashion, thus preventing the torsional force and resulting twisting that cause micro-cracks to develop. The spindles are of a sufficiently large diameter to facilitate operational use of the fiber while stored on the spindle without increasing the attenuation of signals that could result from the use of a smaller diameter spindle.

  • Publication number: 20040001721
    Abstract: Techniques for monitoring optical transmissions between an optical transmitter and an optical receiver are described. A transmitter monitor is coupled to an optical transmitter and detects light, such as reflected light, conducted into the transmitter by an optical cable conveying light between the transmitter and the receiver. The transmitter monitor produces a signal providing information about the light conducted into the transmitter and adjustments are made to the transmitter operation based on the signal. A receiver monitor coupled to an optical receiver detects light conducted into the receiver by the optical cable. The receiver monitor produces a receiver monitor signal providing information about the light and adjustments are made to the receiver operation based on the signal. In addition, an optical signal is sent to the transmitter based on the receiver monitor signal, and the optical signal is used by the transmitter monitor to direct adjustments to the transmitter operation.

  • Patent number: 6564038
    Abstract: A method and apparatus are disclosed for suppressing interference in a radio frequency (RF) communication system using active shielding techniques. An opposing neutralizing signal is applied to actively neutralize stray signals in a microwave communication environment. An interfering or stray signal is detected using a sensing antenna, and the opposing neutralizing signal is generated in response thereto. The opposing neutralizing signal is applied to a signal neutralizing shield to shield any desired components or devices. The opposing neutralizing signal is approximately 180 degrees out of phase, and of equal magnitude to the detected interfering signal. A phase shifter/null feedback device receives the detected stray signal, if any, and adaptively adjusts the phase and magnitude of the opposing neutralizing signal. In one embodiment, the phase shifter/null feedback device includes an integrator that generates a DC value that is proportional to the energy of the interfering signal.

  • Publication number: 20030081905
    Abstract: An apparatus and method that prevents a damaging movement—in any plane—between fiber ends within a connector assembly, where a damaging movement is a movement of the fiber ends with the connector assembly which may give rise to a damaging thermal event while an optical power source is generating a high-optical-power-density signal that is propagated through the fibers. A prevention mechanism is integral to the connector precludes damaging movement. The prevention mechanism includes a) a locking mechanism that precludes any damaging movement while engaged and b) an indication generator that upon being engaged or disengaged generates an indication that can be used to control the on/off state of the optical power source.

  • Publication number: 20020097471
    Abstract: A process for optically transmitting data to a remote receiver includes receiving a stream of input data signals and modulating a mid-IR laser by direct modulation with a waveform whose sequential values are responsive of the data signals of the stream. The direct modulation includes pumping the mid-IR laser to produce high and low optical power levels in response to different ones of the values. The process also includes transmitting output light from the modulated mid-IR laser to the remote receiver via a free space communications channel.

  • Patent number: 6331908
    Abstract: A tunable semiconductor laser comprises a gain section having an MQW active region, a uniform pitch grating DFB region, and first waveguide. A composite reflector, including a second MQW region and a second waveguide, forms a cavity resonator with the DFB region. A tuning voltage applied to the composite reflector induces refractive index changes, thereby allowing the center wavelength to be altered.

  • Patent number: 6122875
    Abstract: A component shutter assembly and method of forming same. The assembly comprises a one-piece molded plastic, integrally formed shutter panel. The shutter panel may be molded in a small plurality of standard lengths and then one or both ends thereof cut to shorten the shutter panel to a specific, desired length once it is determined what-specific length of shutter is needed for a particular application. An independent, integrally formed end panel may then be secured to one or both ends of the cut shutter panel and ultrasonically welded thereto to form a finished component shutter assembly having a particular desired length and the appearance of a one-piece, integrally formed shutter. Embodiments directed to raised panel and louvered shutters are disclosed, as is a removable center panel section which may be used in connection with the louvered shutter panels if it is desired to provide a mid-panel section which is offset from the mid-point of the overall length of the shutter panel.

  • Patent number: 6108362
    Abstract: A tunable semiconductor laser comprises a gain section having an MQW active region, a uniform pitch grating DFB region, and first waveguide. A composite reflector, including a second MQW region and a second waveguide, forms a cavity resonator with the DFB region. A voltage applied to the composite reflector induces a quantum confined stark effect, thereby allowing the wavelength to be altered. In one embodiment, the current drive to the active region and the shape of the first waveguide (e.g., a raised-sine function) are mutually adapted so that N longitudinal modes have essentially the same threshold gain and so that the DFB region spanned by the first waveguide is segmented into N zones, each zone providing optical feedback at a different wavelength corresponding to a different longitudinal mode.

  • Patent number: 6081361
    Abstract: In a WDM fiber-optic network, a unique laser transmitter enables signals to be routed at three hierarchical levels: at one level discrimination among signal paths is based on N WDM wavelength channels, at another level discrimination is based on m AM subcarrier frequency channels, and at a third level discrimination is based on n FM subcarrier frequency channels. Thus, a total of Nmn distinguishable optical channels can be accommodated and a like number of users served. The laser transmitter comprises a broadband, tunable semiconductor laser which includes an intracavity, integrated composite reflector to which a tuning voltage and a FM dither signal are applied, an intracavity gain section to which drive current is applied, and an extracavity, integrated electroabsorption modulator to which an information (e.g., data, voice, video) signal and an AM dither signal are applied.
