Going to throw this out there, I’ve already spent almost an hour looking on google and not finding anything…
Does anyone know of an optical converter/adapter to go between 62.5um multimode and 50um multimode fiber? Seems like it would be a simple thing to produce and publish the loss values.
Reason, I bought a fiber light source and a power meter. The power meter doesn’t seem to care too much on the size of the fiber and which adapters I use to get the connectors to latch. But the light source was designed with an LED and a larger aperture LED… Using 50um cable results in a very large loss! Using a 50um LC connector through adapters is a huge loss (like -24dbm). After going round and round with the “manufacturer” and making several videos showing the problem, I finally bough a new cable that could be used with no adapters and it still has a problem. They just refunded me all me money for it and never even asked to return it (direct from China). They know that I know why it doesn’t work with “modern” 50um multimode cables (OM-3, OM-4, and maybe OM-5) and that it can’t work without changing the light source for a 50um compatible source. Yes I had to re-teach myself on all this stuff, never really been up to speed on fiber to begin with, but this certainly pushed me to figure it out.
So asking if anyone has seen an adapter/convertor that can be used to go from 62.5um source to 50um fiber, and hopefully for relatively cheap.
The single mode side of the light source works great, but the multimode is what I run at work and will run at home as I move towards some 10gbe stuff in my lab rack. Nothing I currently do requires the distance out of single mode fiber and I certainly wouldn’t try to run it 6 feet from switch to server in my lab.
