Abstract: Methodologies for designing and assembling an analog Nyquist filter require a filter unit which includes a low pass filter in cascade with at least one tapped delay filter. A Signal Generator is used to generate a test pattern for input into the filter unit in order to create a reaction signal from the filter unit. This reaction signal is then compared with a desired Nyquist response. Based on this comparison, amplifier gains for taps in the tapped delay filter are weighted to establish a transfer function in the filter unit. In operation the transfer function shapes analog input signals with the desired Nyquist response for use as an output from the Nyquist filter.

Abstract: An analog signal processing device for equalizing a low pass filter to create a Nyquist filter in accordance with the present invention includes a low pass filter for passing a predetermined bandwidth, and a tapped delay filter connected with the low pass filter to create the Nyquist filter. In more detail, the tapped delay filter is used to sample an input analog signal having a predetermined symbol rate. The samples from the input signal are then respectively weighted to establish a system transfer function for the Nyquist filter. The purpose here is to minimize both inter-symbol interference and transmission bandwidth. A decision circuit can be provided to convert the input signal into a desired data format for creation of an output signal to be transmitted by the data transmission system. Also, the Nyquist filter can be selectively evaluated as an “eye diagram” and the system transfer function appropriately adjusted accordingly.

Abstract: A system for transporting a plurality of analog and/or digital signals over an optical fiber can include one or more master modems for modulating digital signals and/or RF inserters modulating video signals. The RF signals from the modem(s)/RF inserters are up-converted resulting in frequency bands that are non-overlapping and are spaced apart within a single sub-octave. The sub-octave signal is then converted into an optical signal and directed onto an end of an optical fiber. At the downstream end of the optical fiber, the received optical signal is converted to an RF signal at an optical receiver. The RF signal is then filtered, down-converted and directed to a selected coaxial distribution unit. From the coaxial distribution unit, the RF signal is demodulated, e.g. at a slave modem, to recover the initial analog and/or digital signal.

Abstract: A system for transporting a plurality of digital signals (i.e. “n” digital signals) over an optical fiber includes a plurality of modems for modulating each digital signal on a respective analog signal. Each resulting RF signal is processed by a corresponding up-convertor, which includes a mixer and local oscillator, to produce a frequency band which can be a double sideband or single sideband of the modulated signal. The resulting frequency bands output by the up-convertors are non-overlapping and are spaced apart within a single sub-octave. An RF combiner combines the frequency bands and the combined RF signal is converted into an optical signal by an optical transmitter that outputs to an optical fiber. An optical receiver converts the optical signal from the fiber to an RF signal that is directed to an RF splitter. Signal fractions from the splitter are filtered, down-converted and demodulated to recover the initial digital signals.

Abstract: A system and method are provided for transmitting multi-octave telecommunications signals, as sub-octave signals, on an optical fiber. Using different modems, digital signals are modulated onto respective radio frequency (RF) carriers. In detail, the resultant RF signals (fn) are all within a same lower frequency band. At least one fn is a multi-octave signal. A frequency changer switches each fn (possibly multi-octave) from the lower frequency band to an upper frequency band, where they avoid overlapping each other, and where they are each established as a sub-octave signal (f?n). A combiner then groups the individual sub-octave signals (f?n) into a single sub-octave signal (f?). Further, an electrical/optical converter creates an optical signal of wavelength (?) for transmitting the combined sub-octave signal (f?) over the optical fiber.

Abstract: A system for regulating the signal strengths of a plurality of Radio Frequency (RF) signals to reduce signal degradation includes a plurality of controllers. Each controller is operably positioned upstream of an electrical-to-optical converter which generates an optical signal for transmission over a fiber optic transmission path. Each controller functions to detect and identify RF signals whose strength exceeds a maximum value and immediately attenuate the RF signal to prevent the transmission path from being jammed by the signal. Each controller also performs a signal leveling function by sampling signal strength, over time, and uses moving window averaging or some other moving window statistic to level the RF signal. Structurally, each controller includes a detector, a signal attenuator and a signal amplifier that are operationally positioned along a signal path extending from a controller input port to a controller output port and are operationally connected to a processor.

Abstract: A system for transmitting an optical signal over a fiber optic includes a terminal for generating the optical signal. Due to its modulation, the optical signal includes a carrier having a wavelength “?”, with an upper sideband and a lower sideband. A tuner is connected with the terminal to adjust the wavelength “?” of the carrier of the optical signal relative to a band pass filter. The purpose here is two-fold. For one, this adjustment eliminates a sideband of the optical signal, to avoid fading, and it suppresses the carrier of the optical signal, to enhance the OMI while maintaining the linearity of the signal.

Abstract: A system for transporting a plurality of digital data streams over an optical fiber can include a plurality of upstream quadrature amplitude modulation (QAM) modems. Each QAM modem encodes a digital stream onto a carrier signal by modulating both the amplitude and the phase of the carrier signal. Each QAM modem also up-shifts the signal frequency, with each up-shifted signal having a frequency within a single sub-octave frequency band to suppress composite second order distortions that can occur during optical transport. The QAM signals are combined and converted to an optical signal that is transmitted over an optical fiber to a receiver. To convert the signal, a voltage source is connected with an electro-absorption modulator to provide a bias voltage for altering an optical power of the optical signal with a DC offset. The DC offset minimizes third order distortions of signals transmitted on the fiber optic.

Abstract: A system for transporting a plurality of relatively low-frequency information signals over an optical fiber can include a plurality of transmitters. Each transmitter receives one of the relatively low-frequency information signals as an input, processes the input signal, and outputs an up-shifted (i.e. relatively high frequency) signal that has a suppressed sideband to reduce transmission power requirements. Sideband suppression is accomplished using a technique in which a first component of the input signal is shifted in phase by 180 degrees and summed with a second, in-phase signal component. The signals output from the transmitters are then frequency stacked and the resulting signal is converted to an optical signal for transmission over an optical fiber. The up-shifted signals output from the transmitters have frequencies within a single sub-octave frequency band to reduce the adverse effects of composite second order distortions that can occur during optical transport of the information signals.

Abstract: A phosphor plate includes a glass layer, a wide-angle reflection dichroic filter and a phosphor layer. The wide-angle reflection dichroic filter is disposed on an exit surface of the glass layer. A first blue light and a second blue light of the incident ray are transmissible through the wide-angle reflection dichroic filter. The phosphor layer is disposed beside the wide-angle reflection dichroic filter. By the phosphor layer, the first blue light is excited as a first green light to be outputted and the second blue light is reflected to the wide-angle reflection dichroic filter. The second blue light and a portion of the first green light outputted from the phosphor layer are reflected by the wide-angle reflection dichroic filter, so that the portion of the first green light is transmitted through the phosphor layer and the second blue light is excited as a second green light by the phosphor layer.

Abstract: A system for transporting a plurality of digital signals includes a head-end unit for routing each digital signal to a particular modem, according to address information in the signal. At its respective modem, each digital signal is mixed for further transmission on a unique, modem-specific, radio frequency (fn) that is predisposed for a sub-octave transmission. A first converter then “stacks” a plurality of the different digital signals onto a common wavelength (?) for transmission as an optical signal over an optical fiber. At the receive end of the optical fiber, a second converter “de-stacks” the plurality of digital signals, and segregates them according to their respective unique radio frequency (fn). A distribution unit then directs each unique radio frequency signal to an addressed node for further transmission over a secondary network.
