We bought around 60 or so 10Gb LR SFP+s from FS aswell, 8 were DOA but not had one fail in use as yet.
Haven't got many Solidoptics ones in use, but have had a couple of theirs fail, though they are keen to tell us how bad FS ones are... Never had any problems with anything from Flexoptics so starting to think they are worth the extra cost. Regards David Howes ----- Original Message ----- From: "Neil J.
