Determine the side "reception" of the SFP optics

Hello.

I have an upcoming implementation of dark fibre which requires me to run ZX SFP (cable distance of more than 10 k), but I need an attenuator in the side reception of the FPS at each end.

How I think we're the receiver?

With SFP 1350nm, it is not 'light' to see the exit and the number which is the transmitter, as it is on 850nm SFP - so, how do I do to the longer wavelength, those?

I've been unable to find a representation of the disgrametic of a CWDM SFP that indicates a specific - is it reasonable to assume a SFP WDM standard, is not the same thing?

Or should I connect with the attenuator on the one hand, check the input power, and then plug it into the other side and see if it makes a diference?

Thank you.

Look at Figure 1.

  • Is there a way to dynamically determine the number of parameters to a procedure side Server?

    Hello

    This is a helper method used to call a server-side function that traverses the bindVars parameter to fill the PARAMETERS of the function. Is there a way to dynamically determine the parameters input/output based on the procedure name in the stmt parameter? No member of the CallableStatement class looked promising, but the getParameterMetaData() in the PreparedStatement class method seemed it might be useful lead. However, I have not found any (yet) a detailed description of how to use it.

    protected Object callStoredFunction (int sqlReturnType, String stmt,

    Object [] bindVars) {}

    CallableStatement st = null;

    try {}

    // 1. Create a JDBC CallabledStatement

    St = getDBTransaction () .createCallableStatement)

    ("" start?: = '+stmt+ ";" end; ", 0);

    // 2. Register for the first variable binding for the return value

    st.registerOutParameter (1, sqlReturnType);

    If (bindVars! = null) {}

    // 3. Loop on values for the bind variables passed, if any

    for (int z = 0; z < bindVars.length; z ++) {}

    // 4. Set the value of vars binding provided by the user in the stmt

    st.setObject (z + 2, bindVars [z]);

    }

    }

    // 5. Set the value of vars binding provided by the user in the stmt

    st.executeUpdate ();

    // 6. Returns the value of the first variable binding

    Return st.getObject (1);

    }

    catch (SQLException e) {}

    throw new Aexception.getLocalizedMessage (e);

    }

    {Finally

    If (st! = null) {}

    try {}

    // 7. Close statement

    St.Close ();

    }

    catch (SQLException e) {}

    }

    }

    }

    PreparedStatement.getParameterMetaData () subject is exactly what you need for this task.

    Once you have the ParameterMetaData you can ask how many parameters are present, and how they are. Parameters are numbered from 1 to n, and you can use ParameterMetaData.getParameterMode (1); to get the function of parameter 1. The modes are defined as static values of the ParameterMetaData object. Check out the doc at http://docs.oracle.com/javase/7/docs/api/java/sql/ParameterMetaData.html

  • Determine the front panel in memory

    Hello!

    Is it possible to determine, the façade is loaded into memory, programitically?

    Thank you!

    Well, simple rule of thumb:

    LV does not load the memory front panel if it is not needed.

    LV charge front panel in memory if you view it.

    LV charge front panel in memory if the use of knots of property requiring the façade. This info can be obtained from the detailed help for this property:

    LV charge front panel in memory for some methods (also documented in detailed using the method).

    On a side note:

    Please do not mix the execution of code in the UI with the front loading thread. The user interface thread is still running and does not determine the weather (or not) front panels is loaded into memory.

    hope this helps,

  • can you connect the SFP - 10 G - SR low-support to SFP 1000BASE-SX?

    Hello world:

    today I use the SFP + 'SFP - 10 G - SR' in Cisco Catalyst 2960 S-48TD-L connect to the SFP 1000BASE-SX to 6509 WS - X 6724-SFP module.

    the port setting is master, but they do not work, even the light don't flush. Then, I also use the SFP 1000BASE-SX to replace SFP + SFP - 10 G - SR in

    2960 S-48TD-L, then they cany working.

    I look to the top of the cisco data sheet, there is no roadmap to satament database 10G sfp + can't low support 1 G sfp. So, I want to confirm the problem.

    Otherwise, the 10 FPS + can only use for 10G SFP +; can't go down the suport 1 G SFP.

    This means: If you want to use the 10 G SFP + the other old device also need to replace.

    Thank you ~ for your help!

    Hi Marvin,.

    I found this conversation today, because I'm looking for an answer on a question similar to the question that Jerry asked, at the opening of this discussion.

    So my problem is this. In a certain place, I need two 10 GB and a connection of 1 GB on an optical cable. To cut costs, I tried with WS-C2960X-48FPD-L, but because it contains only two ports of SFP +, I tried with two WS-C2960X-24PD-L which will be connected with the battery modules.

    Then, having two WS-C2960X-24PD-L, I have 2 x 2 ports SFP + 1 GB. There are two open questions:

    1. can I put 1 GB transmitter SFP module SFP + port (that I have a connection of 1 GB at remote site)?

    2. can I use two switches to 24 ports mentioned 2960, in a way that I use one of them for the two connections of 10 GB (using ports SFP + 10 GB connection) and the second member of the battery so that we (2 available) port SFP + is used to 1 GB SFP connection (using the SFP port + as mentioned in question 1)?

    I'm not sure if your previous statement covers my questions, because it is not clear if the 1 GB SFP transceiver can be inserted in the port SFP + WS - C2960X - 24PD - L (or any other a port SFP switch +).

  • Determine the best image to overlay size to use

    Hi people

    So I'm working with Premiere Pro CS6 make a video montage of a Minister of my friends. Over pieces of the video, I was just overlap citations and whatnot. I would like to achieve consistency in always making sure that they are included on the same location on the screen. So I thought that a simple way to do it would be to determine the pixel size of the sequence. And the report of properties folder that my sequence is 1440 x 1080. I thought I could just create and manipulate images of this exact size and drop them to the exact location.

    The problem is that when I create an image of this size and drop it in PP, right monitor shows the image with areas of pillarboxed video on each side of it. The image certainly seems to be on-site with the altitude, but the width is off and I don't know why?

    So what is the explanation here? Certainly it seems that properties of the sequence are at odds with what this area right monitor in PP.

    You can specify the PAIR of titles that you create:

    .

    Basically, HD anamorphic uses rectangular pixels

    in order to crush the 16: 9 image in a setting of 4 x 3.

    First use-squishes' back pixels in 16 x 9.

    If your film the layer source is 1440 x 1080 (1.333).

    you are right in a sequence of 1440 x 1080 (1.333)...

    you just need to create the corresponding aspect / securities.

    If you use another application to create your .png images

    I'd be inclined to 1920 x 1080 (1.0).

    This will suit your anamorphic sequence regardless of the BY.

    Hello

    Many TV can make upscan which means that they accept the entry at lower resolution and then fill the entire screen. I don't know your TV/monitor, but normally it can do the work in this way.

    Update: all modern televisions must have a lot of options for entry reports, you can watch old movies (ratio 4:3) on the use of 16:9 zoom function.
