    Hello Dhiman,
    Would you please send me a copy of your project in order to reproduce the problem and figure out the cause.
    Also, send me your email address and affiliation.

    Hello,
    There are many polarization components in OptiSystem 14.0 that can be used to adjust the polarization of modulated signals and enable polarization division multiplexing. These components can be found in Default/Passives Library/optical/Polarization/….

    Hello,
    The MZM is not polarization sensitive. However, you may use two separate signals to represent a signal on each polarization then mix them using polarization combiner. You can find many examples in OptiSystem about using MZM in dual polarization transmission.

    Hello,
    it could be related to your computer memory. Did you try lower number of samples per bit and shorter sequence length? I guess it should work.

    Hello,
    OptiSystem 15.0 that will be released this month has optical and electrical complex conjugate components.

    Dear Ayat,
    there are few examples that exist in OptiSystem that you may use for your project. They are based on scripting.

    Dear Muhammad,
    the X coupler typically has transmission matrix that has built in coupling ratio and internal loss of the device. Both parameters are settable. You need to review the technical information about the component in the software documentation. You may check the “? Help” button in the component properties which gives you more details about the component.
    Regards,

    send me your project layout showing the position of visualizers.

    Dear Muhammad,
    This visualizer automatically detects, calculates and displays the optical power, noise, OSNR, Gain, noise figure, frequency and wavelength for each WDM channel at the visualizer inputs.

    The Dual Port WDM Analyzer (DPWDMA) estimates the signal and the noise power for each optical signal channel based on the resolution bandwidth for each input port. Click the Analysis tab to view the results (such as gain and noise figure) comparing the signal from the two input ports (see Figure 2).

    More details could be found in the component data sheet.

    regards,

    Hi Anand,
    The best version of OptiSystem to use is the latest version because it has up-to-date software which addresses the market and relative examples. Currently, Optiwave offers version 14 and in few weeks version 15 is coming out.
    regards,
    Ahmad

    It is a bidirectional device, which means you can use it in both directions.
    It should be easily tested using a CW source and a power meter.

    There is a mirror component called “Reflector Bidirectional” in OptiSystem. You can search for it using find component feature.

    There is no issue of CIDF scheduler error found in version 14. problem can’t be reproduced for any data rate.
    it looks there is a bug in version 7 that you use.

    Dear Chennuri,
    there is a component in OptiSystem called “Mach Zehnder Interferometer” that can be used for your application.
    You may contact Optiwave sales at sales@optiwave.com to get quote.
