Hello,
We are looking for large core diameter graded-index silica MMF. Core diameter must be higher than standard 62.5 µm and cladding remaining at standard value of 125 µm. So far, we have found two providers : DrakaElite TM (100/125) and Leoni (85/125). The lengths we need is just a few meters.. Unfortunately Draka sells only 2.2 km minimum and is too expensive for our project. Furthermore they have a strict policy to not send samples.. Leoni they don't have it on stock..
So, is there anybody who use these fibers and could sell us a short piece ? Or maybe anyone knows alternative suppliers for that kind of fiber ?
Looking forward to your feedback.
Cheers,
Miguel
You could try OZ Optics, they are based in Canada, but should have a base in Europe as well

Thank you for your suggestion ! After checking their fiber list, it seems that they don't have what we are looking for, but t I have contacted them just to be sure.

Thank you Sandeep. I had already asked to Fibercore and they don't have such fibers. The large core ones are step-index.. I had already searched on Nufern as well and did'nt find anything, but i will drop them an e-mail in case of..
Try OFS

Thank you O.A. Levring. Problem is that "classical" fiber fabrication involves that cladding diameter must be increased to 140 µm if you want graded core diameters to reach diameters of around 100 µm. We need to stay at standard 125 µm for cladding.. So OFS fiber you propose cannot be used..
