Hi Rhys<br>
<br>
For short MM cable runs you will probably get away with it using that adaptor(~<100meters with a typical 1mW VFL on OM1(worst case scenario I can think of)). I'm assuming your just looking to ID the other end of fiber. ?

That said, mixing MM / SM adaptors is always risky business.<br>
Usually I have a few patch leads(both OM3 & SM(OS1) on hand with the usual ST/LC fiber ferrule for the VFL and a mix of ST/LC/SC connectors on the other end for the various patch panels/fiber types I come across.<br>
Nothing worse thou when you have a faulty fiber, and you can barely see the fiber VFL light, so having the right gear on hand is handy. Fortunately, basic fiber testing gear has come down a lot in price over the years.</div>

<span style="font-size:11.0pt" lang="EN-GB">I have a pretty basic question about VFLs. I haven’t used one before but we need to trace some existing old MMF at a site and am about to buy a cheap VFL that has a universal connector for SC, ST, FC. We need LC as
all the patch leads convert to this. But all the LC female to SC male connectors I can see around are either SMF, significantly more expensive or internationally shipped. Need to get my hands on this for next week.
