Searching the Internet with Google I can find many sellers of fibre patch leads but none of them state factors about their fibres in their spec sheets like the refractive index of their fibres or the V number, or NAs. If they were all different you would need matching optics etc. Is this because this is standardise across the board, so all patch leads will have the same figures? If so, what are the standard values here? Where can I see the standard?
Many thanks!
