    It’s done!
    Weeks of testing and developing of switch options and a international broadcast venue for live testing…

    I’ve tryed so long to tunnel GigaACE (PRI/SEC), Dante (PRO/SEC) and Control over different VLAN’s over a 10G SFP+-Lightpipe trunk.
    Now it happens…
    I’ve done the UEFA Championsleague -and Euroleague-Draw in Monaco a few days ago.

    Setup:

    DLIVE S5000 (Optioncards: Dante + SRC-Adapter)
    DM64 (Optioncards: AES, GigaACE, Dante128x128)
    2x DX168 (1x Stagebox, 1x Console)
    IP8 (Console)
    4x Microtik CSS326 with 10G SFP+ Modules (Singlemode 10km) [2x Promary / 2x Secondary)
    Lightpipe 200m SC/SC Multimode (8 pipes) I’ve used 4, the other 4 pipes are spare and connected to Mediaconverters. (Plan B Scenario)
    The Bandwith of the lightpipe-trunk was ca. 1,5 Gbit (GigaACE+DANTE+CONTROL) per switch

    GigaACE is a very fragile protocol. It’s absolutlely necessary to deactivat every Layer3-Feature. The switch has to act as a Layer2-Switch.

    At the end, the setup worked very well for me. No Audio glitches at all. Only on thing annoying me… after ca. 5-10 Minutes an error shows up ‘Console sync recovered’ but no Audioglitch in the connected Audiocards and Stageboxes…clean signal.

    For this kind of live-broadcastshow I had 80 Inputs and 90 Outputs (Tielines+Consoleoutputs) and ca. 100 Channels of Dante…
    The whole 4-wire Intercom is tunneled vie tielines through the GigaACE and all wireless mics (Shure Axient Digital) are connected and controled via Dante 96KHz

    For me the time of yamaha is over. I’ve used a PM7 in the past… but the Dlive is mutch more flexible and so intuitive in the way of patching and routing…

    Please contact me for questions. And if anaybody has a hint for my sync message of the console… please feel free to contact me.

    Regards
    Florian

    Here are some pics of the job.

    I’ve worked for PRG and Production office Germany.

    I’ll be glad to join you. This is an interesting application!

    Note: It is known that the ACE connection can only run via Layer2 Switch. It can also be found somewhere in the manual 🙂

    I recently tried to connect a DX168 with simple TP-Link fiber optic format converters via fiber optics. Unfortunately this didn’t work, I had clicks and didn’t get Preamp control. Unfortunately you can’t access these converters.
    Does anyone know any format converters that can solve this problem?

    I’ve used this TP-Link converter for years… TP-Link MC200CM (2x Primary, 2x Secondary and 2x Spare off course!)
    But now, I’m going with the mikrotik switches…
    for short distance (100-300m) I use Singlemode SFPs and Multimode fibre. It works without problems. (Singlemode Transceivers have more transmit power.
    Also the Adapter patches from SC to LC are Multimode. Only the SFP+ module is Singlemode

    that’s interesting. i thought so far that you can’t mix single and multimode, because they are different cross sections and i suspected that the lenses would have to be cut differently, because the angle of light entry is much narrower in singlemode. I must have misunderstood that.

    some video guys gave me this hint…

    with Multimode SFPs and MM Core+Patches 250m I have a cable loss of 3-5dB
    with Singlemode SFPs and MM Core+patches I have only 1-2db cable loss.
    Singlemode Transceivers are made for distances of 10km+… 250m is only a patch in singlemode-world 🙂

    best regards

    I guess a singlemode transmitter would work with multimode fibre but not the multimode transmitter with single mode fibre

    and btw not all singlemode SFP transmitters are made for long distances

    This is interesting indeed, I too use the TP-Link media converters with Gigace, 4 units plus a spare (😉) but the single mode and multi mode thing is news, wish I had this information earlier. It has been very reliable system for sure.
    I think the longest distance I have tried is 250m surface to mix rack. I have also used optical connectivity on the MADI card to feed various broadcast trucks again all successfully .
    Great system might have to give the 10Gb networks a look, thanks

    I tried to do this last summer with a Microtik CRS328 but the 1.8 firmware wasn’t out yet so the dLive wasn’t playing nice with VLANs and trunks.
    I’m keen to revisit.

    Did you actually manage to get the DX protocol working through the switch? I battled with this for days but kept getting glitches.

    Now they have removed the vlan tagging from gigAce, do I just connect the surface and rack onto the same VLAN with nothing else on it or do I connect it to a trunk port and somehow configure the VLAN of the rack and surface?

    Florian, are you able to share your Microtik config, I’m interested to compare it with mine to see if you found more stuff to turn off than me.,

    I also found that when I carried DX traffic, it resulted in a crazy high CPU load on the switch. I raised a ticket with Microtik but I never got to the bottom of it. How does your CPU load look?
