I just picked up on LC-LC cables at Fry’s and I haven’t seen any problems with them (knock on wood). I think the ones I bought had a certification on them, couldn’t tell you which one though I tossed the packaging.
As long as the glass isn’t broken and the ends are on good, and the cover is consistent all should be good.
I buy cables from cdw. Usually they are belkin, but occasionally other brands. But I havent yet had any issues.
