HD MADI fiber mode ?
Hi all, quick question about the fiber connections on the HD MADI interface. Are they single mode or multimode ?
The manual states only that the maximum distance is up to 2km.Which is kinda confusing since some sources says the multimode is capable up to 200m, others - up to 2 km..... |

Re: HD MADI fiber mode ?
Multimode
Distance is determined by MADI wavelength (there are a lot of different types and two types of emitters) and then also the cable. Just listen to the manual and don't worry about other sources.

Re: HD MADI fiber mode ?
So if my source is coming via LC Singlemode 1300nm can it be adapted to plug into HD MADI? Would it work? TIA!

Re: HD MADI fiber mode ?
The LC part means nothing hard. That's just the connector body style, you can always get an adapter cable to do that. SC is the standard in MADI. It's the multimode to single mode and visa versa that matters. Or is it visa versa? Is this a simplex feed or a ring/duplex feed? E.g. does the other end need to clock over MADI from your HD MADI? etc.
Mmm where can you find an old cheap FDDI multimode to single mode converter... expect they would work. Not sure with all the more modern Ethernet MC to SC adapters... depends on what they are doing exactly, would be interesting to test them. RME lets you specify, at least on some of their MADI products, if you want a single mode fiber interface, and obviously you can chose to swap a SFP multimode or single mode transceiver in any that use SFP. I am not sure but you could check with RME if they can offer single mode on the MADIface USB, and then you can use that as a stand alone single mode to coaxial copper adapter. A poor-man's MADI router, you can even mess with channel routing in TotalMix and leave it set up stand-alone. If you have a more complex setup then the RME MADI router I believe can be ordered with single mode ports, or maybe RME can let you know their plans for the initially unused SFP ports. https://www.rme-usa.com/madi-router.html Otherwise there are other companies out there that sell adapters you can probably Google for. Edit: was trying to recall who else I was thinking of, it's these guys: https://appsys.ch/en/products/flexiverters/flx-madi Last edited by Darryl Ramm; 12-10-2022 at 04:45 PM. |

Re: HD MADI fiber mode ?
What source is single-mode today?
That's your problem.

I'm willing to cut lots of slack if it's a big spiny thing made in Switzerland.
