Re: Cisco MDS9148 fiber cable

You can use both, but in SAN land 50mu is the cable most commonly used. But beware of connecting 2 patches together: try not to do that or if you need to, use the same specs. And another thing: 50mu can reach further than 62.5 and then there's the OM2, 2, 4 specs. OM4 can reach the farthest. I don't know the distances by heart, but I'd try to maintain some sort of standard. So once you go 50mu OM3, try to use that for all patches. But that's cosmetic.
