Does anyone know if these are compatible with other brands of fiber converters? Specifically, the AJA FiDO optical miniconverters? I have several of the AJA ones, and would buy some BMD ones if I knew they were a compatible fiber standard, where I could have an AJA on one end and a BMD on the other.

Anyone confirm they work together? Or confirm they do NOT?

haven't tried them with FIDOs yet, but they do seem to work with Rattler2, cheap chinese units, and some of the studio technologies units. Since HD-SDI is a standard, I'd be willing to say they would work with FIDOs too...

BTW, they pass MADI audio (coax) as well as HD-SDI

they are compatible with all smpte standard units transmitting or receiving on 1310 wavelength.

Thanks, guys. I finally did find another thread on this, viewtopic.php?f=4&t=2590

Good to know these are all compatible.

since the sfp's should be compatible with any smpte compliant sfp i would like to see if anyone has considered replacing standard sfp with a wdm bidi sfp so that one fiber could be used to tx and rx

ditto!!

someone had mentioned doing just that a few weeks ago, but never came clean with any model info. would LOVE to do this, or have BMD offer this.

I think the real question here is the BMD box side of things ... Does it need a specificly programmed sfp like many Cisco , HP etc switches which won't recognize just any old sfp converter ...

I don't think they are smart enough to think the sfp id through. they can't even get the frame syncs to work on the 2ME. and for the record i use generic sfp's in my linksys/cisco switches

found a miranda unit that is tx/rx WDM single strand but over $2k. if anyone has one of these could try a module swap...

touche' haha

i would be curious about the 4k line as well ... per this topic viewtopic.php?f=18&t=12645&hilit=4k+mini+converter+optical+fiber

we have all hp stuff running multiple vlans for audio control internet etc ... HP is fairly picky there is plenty of 3rd party stuff "programed" for hp that works great but you just need to be sure its compatible ...

I think lynx makes a similar miniconverter product too sure would be nice of bmd to chime in on this !! we can all but hope they have someone who knows about their products

multiple VLANs for audio control internet….

wow that sounds like something sitting right in front of me! great minds…

i did try your 4k idea with a sdi dual link mux, didn't work though…ended up with a bunch of Studio Tech Model 410s, but VERY pricey. They do work exceedingly well so happy with the purchase. I get three feeds per fiber. with the mini conv down to $295 now, its still much cheaper to buy more strands of glass…

what i'd really like to find is a cheap fiber wdm and some ethernet devices outside the 1310nm window so i can stack data on top of the BMD video.

were they all in time my thought was to "trick" the 4k mux to think its all the same source all feeds needed to be genlocked?? but not surprised that the 4k mux was to picky to work =( sad ... studiotech makes great stuff but yeah they are proud of it!

I had hoped they would lower the cost of their opengear cards too since they are essentially the same hardware !?! asked but crickets ...

you should be able to find ethernet device easily but you are right most all sdi links seem to be in the 1310 wavelength ... check out lynx yellobrik stuff they have some sfp's that are mux/demux able along with a 4 and 9 ch mux ... no idea of cost ?? but i have seen their devices used and they seem to be solid.

Yeah been looking at this as well. The 4 channel yellowbrik mux is like 1500$ a side.

I will need 2 on each end...$6k. I can buy a lot of fiber...or anything for that much! Thor makes some components for about 150 ea. Even that is a little over the bang for the buck line as at the moment it will only save me one strand of glass to do this.

The cost of the single strand of glass is rarely the issue. It is getting that strand of glass IN PLACE that runs up the cost. At least for many of us, and certainly for me. When you have to dig trenches to bury it for a couple of miles, the cost of the glass is insignificant.

Yeah has nothing to do with setups. It's all about how much you can stuff down an already installed fiber. Mostly for us it's useful when interconnecting buildings with limited fiber infersrtucture. Being able to have ethernet, multiple sdi feeds back and forth and madi over a single fiber is awesome. And the $6k is nothing in the whole scheme of things when your talking that scale.
