摘要： An optical network monitoring system and method thereof are proposed. An optical line terminal (OLT) transmits a first optical signal to a plurality of optical interference devices. After the first optical signal passes the optical interference devices, the optical interference devices reflect back a plurality of second optical signals corresponding to the optical interference devices respectively to the optical line terminal. The second optical signals have different optical path differences. An optical/electrical converter unit converts each of the second optical signals into an electrical signal. A spectrum analyzing unit analyzes the electrical signal to extract a frequency component of the electrical signal, thus the fiber connection status to each optical network unit in the optical network system could be obtained. Therefore, the purpose of monitoring the optical network system is achieved.

摘要： A non-sampling-based Q-factor measuring apparatus and method use a power conversion module to transform the power variation of inputted optical signals in time domain into the variation in other domains, such as optical wavelength, optical polarization and different output ports of optical elements. Taking optical wavelength as an example, different levels of power variation respond different outputs of wavelength variation through the use of a power-to-wavelength conversion module. An optical filter then separates the inputted optical signals with different wavelengths. The power average of a wavelength for its corresponding optical signals is further calculated by a photo detector. Thereby, the information of the power variation for the inputted optical signals at levels 1 and 0 can be obtained, and the Q-factor for the inputted optical signals is easily measured.

摘要： An apparatus and method for simultaneous channel and optical signal-to-noise ratio (OSNR) monitoring is adapted to function in multi-channel wavelength-division-multiplexed (WDM) optical communication systems. A polarization controller is sequentially adjusted to perform the sequential polarization control with an optical signal. A polarization-selective electro-optic modulator acts as a polarizer and provides a signal dithering to improve the detection sensitivity. A beam splitter splits the dithered optical signal into two clusters. A photodetector receives the first cluster and measures the OSNR. An optical element receives the second cluster and monitors the channel wavelength of multiple channels. The apparatus can be packaged into a compact module and integrated on a chip. The channel monitoring covers a wide wavelength range and is tunable. The OSNR monitoring can be accurate over a wide dynamic range.

摘要： An apparatus and a method for monitoring optical signal-to-noise ratio are provided. It can be applied in dense wavelength-division multiplexed networks to monitor the transmission quality of each optical channel. The apparatus comprises an optical circulator, a tunable optical filter, a dithering signal, a dithered reflector, and two photodiodes. It can be integrated on a single chip. The invention utilizes the dithering and reflection functions of the dithered reflector, and passes the signal and the noise through the tunable optical filter once and twice, respectively. When the tunable optical filter is scanning and filtering the whole spectrum, the signal and noise powers are measured by the two photodiodes, respectively. The OSNR for each optical channel is then calculated according to the signal and noise powers. It can monitor channel location, wavelength drift, and OSNR by including a wavelength locker to act as an optical channel analyzer.

摘要： This invention demonstrates an adjustable monolithic multi-wavelength laser diode array formed on a substrate a plurality of diode lasers, each has an active section and two mirrors with similar multiple reflectivity peaks. A phase control section can also be included in each laser for fine tuning of the laser wavelength. Each laser in the laser array can emit light at the same wavelength or can be easily tuned to form an array with multiple wavelengths. To serve as an application example of this invention, sampled grating DBR lasers are designed to form a laser array with adjustable multi-wavelength outputs. By varying from laser to laser the sampling periods of the sampled gratings in each laser, a uniformly-spaced multi-wavelength laser array can be achieved with a simple tuning mechanism. The lasers can also emit light at the same wavelength or be tuned to other wavelengths by tuning the sampled grating mirrors. The technique for fabricating the laser array is similar to that for conventional DBR lasers and is already well established. The invented multi-wavelength laser arrays can find applications in WDM systems to offer the advantages of high performance, high reliability, compact size, and high speed.

摘要： An all-optical label swapping system and method superimposes a low-speed ASK label on top of a high-speed DC-balanced-line-coded ASK payload. An old ASK label is erased by modulating the combined payload and label signal with the inverse of the received ASK label.

摘要： An apparatus and method for measuring a coherence sampling quality-factor (Q-factor) are provided, which are used to monitor quality of an optical signal in an optical network in real time. The quality is evaluated by a Q-factor. A laser diode and a wavelength converter are used in the apparatus to achieve wavelength coherence and amplification of the optical signal. Furthermore, the laser diode and an optical switch are used together to obtain an optical pulse that can be utilized to sample the optical signal. Therefore, after entering into an optoelectronic converter, a baseband signal in the optical signal is reconstructed through the amplification of the optical signal and the coupling of the optical pulse, so as to detect the Q-factor and to monitor the quality of the optical signal.
