    Select the report page, drag and drop a 2D graph into the report,then from the Project Browser, select the Fiber Length and drag and drop the parameter X shift into the X-axis of the graph. finally, From the Project Browser, select the BER Analyzer and drag and drop the result BER into the Y-axis of the graph.

    Regards,

    Dear friend;
    Mostly semiconductor lasers are used for FSO. There are several advantages of semiconductor lasers for free space optics (FSO) compared to LEDs: Better optical spectrum, high optical output, advantages for beam shaping, and so on. There are several atmospheric transmission windows and high quality semiconductor lasers with a suitable wavelength for these windows are available.
    One big advantage of FSO is the possibility to install a link within hours because there are no construction permits and time consuming construction work necessary.

    This file is OptiSystem SAC-OCDM sample as far as I am concerned (so you can find it in OptiSystem samples). I ran the simulation and it went smoothly with acceptable results except for the third user (which you should first enable in the simulation BTW). If you cannot open the file or do the calculation, this is a technical issue and you should contact Optiwave, which will probably answer after the weekend.

    Optical wireless communications (OWC) is a form of optical communication in which unguided visible, infrared (IR), or ultraviolet (UV) light is used to carry a signal while Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications

    Hi mohammed;
    it is not called circle laser,it is called continuous wave laser so the most important parameter is wavelength and there are many other important parameters.
    i hope to be benefited to you.

    you want to put a clear visual image on your research paper, then i would say that this is not the standard way of representing the schematic because you will see in standard journals the authors are not taking a screenshot rather they are drawing manually at some tool such as Microsoft word or others tools are also there. I am still not clear for what purpose you want to do so.

    i suggest you to keep same launching power for every transmitter and check the result for each receiver and proceed in a same way for different power levels using sweep concept. For varying the fiber length , you can also use the sweep concept and check the performance for different lengths

    it occurs due to consumption of large RAM of your PC then i suggest you to go for RAM addition if you have not done so far…Maybe that will help

    you can design your system in Optisystem as well and i guess no need to design wireless part in any other software. I am posting few links where the topic fiber-wireless has been discussed.

    If you are using null as input to your Matlab component, you sould find a way to create the output vectors which are normally created by the code “OutputPort1=InputPort1;” always suggested by Optiwave to be used as the first line of the Matlab program.

    please specificy the part you need the Matlab code for… Without specifying that information it will be difficult to understand what exactly your problem is

    i had suggested in previous post that you could make these changes by using MATLAB code..one thing you can do is convert the phase from degrees to radians using a MATLAB module..i guess this could be a way easier way to do it

    can simply choose the mentioned components and make the required design and regarding the parameters of DDF and DSF i believe the parameters in which changes have been made is specified in the figure itself. I thinks the person who has designed it would have specified the changes he has made in parameters and they seem evident in the figure itself.

    I presume that there must be some error which your friend makes while dealing with optigrating. As you know the equations are same in both the tools hence the probability of being incorrect of any of the tool is very small. I would suggest you to do exhaustive analysis on using it in optigrating and compare it with results shown by MATLAb. There must not be a huge difference.
