2 meter 10GB cable - cooper or optical?

I need to connect to the server FPS + with switch Cisco SFP +. They are very close between them, so I need just 2 metres of cable. I can do this with two cables:

or the other

Assembly of optical cable Active SFP - 10 G-AOC2M of Cisco

or

Together cable Cisco SFP-H10GB-CU2M Twinax cable, passive, 30AWG

What are the advantages and disadvantages of these cables? What is the best?

I use the server for commerce, so it is important for me to have the best possible latency and speed.

They are functionally equivalent.

Optical, in general, has more resistance against RF interference, but at a distance of 2 m cases that shouldn't be a problem in all but the most extreme environments of use.

The copper version price is a little less than half the cost of optics.

Make sure that your server switch are compatible with part of your choice. Here is a link to the compatibility of switching matrix.

  • Are compatible cable SHC68-68-EP and SHC68-68-EPM cable?

    I use a DAQ card 6062E with a chassis SC-2345.
    For now, to connect with each other, I use a SHC68-68-EP of 2 meter long cable.
     
    Now I need a longer cable, this cable is only 2 metres but I need 5 meters.
     
    My question is: are SHC68-68-EP and compatible SHC68-68-EPM cable (for M-series cards)? (the EPM cable exists in versions 5 m and 10 m)
     
    Tips: 
    1. I downloaded the two support cables wiring diagrams OR. The only difference is: the new cable (EMP) for M-series cards, a PIN which was formerly assigned to GND is now separated into a new pair twisted and assigned to a signal (PFI 15 / P2.7).
    According to this, it seems that 'new' EPM cable can be used on other maps than M-series of retro-compatible way (but of course 'old' EP cables cannot be used on M-series cards because a single signal would be connected to the MASS).
     
     
    2. The SHC68-68-EP cable, I bought 3 weeks ago had a big label "NI SHC68-68-EPM" on his bag when I got it... Maybe OR ships 'new' EMP cables when order us EP cables 'old '?
     
     
    Does anyone have information about it all?

    Hi Fabrice,.

    It is possible to use the EPM cable with your E Series device. Changes to the MOU to create the EPM have no negative effect when used with the E series devices.

    The main difference between the two cables is the assignment of pins for PFI 15 (as you said). Cable EPM has also been optimized for digital extra lines on M Series devices to minimize noise and crosstalk on the PFI lines.

    Let me know if you have any other questions.

  • TV Toshiba 40L3433DG - not coaxial audio work?

    Hello!
    I'm sorry for my sentence, but English is not my natural language

    I have a problem with a coaxial audio output in TV Toshiba 40L3433DG, which is connected to the home theater LG BH6530T via coaxial converter in French - output optical. Home Theater is not playing the sound of the television but detect a TV - input optical signal is active in home theater settings, after that disconnect the cable TV coaxial, optical entry into a home cinema is inactive. I tried to play sound from TV programs (DVB - C), video from a USB key connected to the TV and YouTube.

    I first thought that the problem is in the coax - optical converter, but I borrowed from my DVD player old parents with coaxial output, I connected the coaxial cable from TV to DVD and home theater has started playing the sound sent from the old DVD drive. In this way, I have eliminated the potential problems with the coaxial cable, converter cable to fiber optics and optical of entry into home theater.

    There's the television... Now my question - does this kind of TV has a special option to activate the digital audio output? In the sound settings, I can choose digital output PCM or compressed. If the TV does not have a special option to activate the output, is the possibility to use a test mode to check the coaxial?

  • Install a secondary hard drive

    I have a small form factor and want to install a second hard disk in the optical drive.

    The new Seagate drive came with all the SATA cables. and the optical drive cable usual additional split from him. One of these cards is part of the new drive, but one that goes to the motherboard is too short to reach the appropriate connector. Seems that I just need a very short extension, but when I do my shopping for one I'm overwhelmed by a mess of all sorts of types of plug SATA cables and cable whose pictures are not clear enough for me to recognize exactly what I need.

    Can someone advise me please I need re this plug on each end, as well as the extension of better quality? Guidance appreciated.

    Clueless in Cableland,
    Rob

    Hi, Rob:

    I don't know what you plug installed on the hard drive, but like I said if it was the biggest power supply sata plug, I think what you need is then the sata data cable.

    One with a female end straight to the motherboard and the other female 90 degrees on the hard drive.

    SATA cable speed ratings do not matter.  Just get one that will reach from the motherboard to the hard drive.

  • Is it possible to route signals of relaxation between two chassis PXI-1002 with the PXI-8335?

    Hello

    as the subject says, I am interested in the delivery of a signal to trigger between two chassis PXI-1002. At present, these two chassis are connected by a MXI - 3 system using maps PXI-8335. The software is Labview 2010 sp1 and 380 NIScope drivers.

    We want to keep (a PXI-5122 by chassis) scanners supply separated due to the requirements of our measure! The chassis are connected via cable to fiber optic. This explains why I can not just use the shutter release in Star, or connect via 'Trigger' or 'clk' cards (the inputs / outputs to the front of the cards).

    I found a few examples, but they seem to all be designed for use with a chassis only, I'll call later to the examples that inspired me to this point. Each guide explaining the synchronization of several chassis systems seems to use another material or VI is not accesible to me. This makes me wonder if my hardware has the capacibilities I need.

    The first picture shows approximately where I started from (sorry I can't post VI, confidential...):

    Only the middle part is interesting. Two sessions are initialized and manipulated parallel, trigger too. This has led to delays in the signals and should now be fixed. This apart from the VI works fine.

    Goal is to trigger only on one channel but both devices! If possible, the device will trigger must be chooseable.

    I started to rebuild the VI using the "EX Synchronization.vi 5xxx niScope' seeming spontaneity. The result is shown in the following image:

    I tried different RTSI lines, but had no positive results. only the main channel has triggered.

    After this first approach, I looked in the "niScope EX .vi multi-Device configured Acquisition (TClk)" and other examples of TClk which seem to work for similar problems. The VI of reconstruction can be seen in the following images:

    (Sorry, I had to use two photos..)

    In this case, I didn't have no choice for trigger lines, it would automatically set the VI TClk. I tried to trigger on both devices, though. This second approach seemed promising to me, but it was an error:

    "niTClk Synchronize.vi:1".

    Index (starting at zero) of the session: 1

    The error reported by the pilot of the instrument:

    No registered trigger could be found between the
    devices on the route.

    If you have a PXI chassis, the chassis correctly identify in
    MAX and make sure that it has been configured correctly. If you use PCI
    devices, make sure they are connected with a RTSI cable and that the cable RTSI
    is saved to the MAX. Otherwise, make sure that there is an available trigger line
    the trigger bus shared between devices.

    Target unit: PXI2Slot4

    "Status code:-89125"

    This error came back even after I've identified this drug as possible to the MAX, as shown in the screenshot:

    In some of the textbooks, they showed how to get the MAX trigger lines, but as you can see, there is only booking options in my MAX. Whatever I do, I can't find options to define how to get my trigger signals...

    In principle, it is possible to trigger instruments in different chassis, which is indicated in this Guide and others... the question that remains is can it be done with my set of components?

    I understand that the use of multichassis compromised the integrity of the lines very adjusted as trigger in Star etc., so the configuration should be taken into account in some way, that my approach does not, I knew... But there must be a way to do this? And to start: to get just any signal from one device to the other trigger!

    For any advice on this issue, I would be very thanfull!

    Concerning

    Max1744

    Hi Max,.

    Thanks for the detailed post and explanations of your application and requirements. You're right using TClk, because this is the optimal method to synchronize the 5122 digitizers. The original VI you worked with is unique for some of the legacy scanners and does not directly work with scanners based on the most recent CMS (for example the 5122). The good news is that you can synchronize these cards to separate chassis, but it will use the calendar 66xx and synchronization (T & S) cards in the chassis of the master and the slave, as indicated in the guide that you have accessed. These are needed because a common reference clock must be shared between them as well as a couple of tripping. MXI itself can not handle export triggers and clocks, so there is no way to do this without physically wiring between the chassis with cards T & S. Unfortunately, regardless of what specific method, you use for synchronization, it will take a material extra beyond what you currently have.

    As one of your needs looks like it is necessary to retain wiring between the chassis directly, you may need to consider to synchronize using 1588 or GPS protocols. 1588 Protocol is a system for synchronization on the network while GPS course use antennas and locks for a common wireless signal. Although these synchronization methods may allow you to keep your chassis isolated, they will also require some manual configuration because you would be able to use the TClk synchronization and so the level of synchronization you can get between the cards may not be as good that can physically wire signals between the chassis using T & S cards.

    Hope this helps,

  • Windows 7 "Playback devices" do not recognize all options of reading?

    Hello

    I just changed my motherboard to a 'Gigabyte Technology Co., Ltd. model EP45-UD3P (Socket 775)"because my previous motherboard my have broken, (now I think that he could have the power supply, go figure).

    In any case, during the installation of the Windows 7 OS it have no sound options connected to the motherboard. The first audio option that I hung has my Philips flat screen TV via a HDMI cable to the video card. This was immediately recognized.

    Since then, I've hung up a Toslink cable to fiber optic to the motherboard to the receiver, this is not recognized at all.

    The only option that appear when you right click on the sound icon raise all the audio options and clicking on the 'reading devices' is the HDMI video card on television.

    Why Windows 7 will not be recognized the Toslink or analog options at the back of the motherboard?

    What can I do to fix this?

    I tried the tool audio Microsoft fixit, but nothing happened. Please, is there a way for it to work properly. Thank you.

    John

    After contacting the seller on eBay and them, which suggests looking in the BIOS I was able to get all the play back option to appear to "activate" the audio option under Advanced options in the BIOS.

    The seller said that this motherboard has already been used in a HTPC (Home Theater PC) and only the HDMI necessary option available.

    Here, the issue is resolved and I am able to listen to my music and movies through the optical audio or Toslink option so I'm a happy camper!

    Now, if only to get the IR to work with the remote for their 2250 Hauppauge TV card.
