NMEA 2000 Questions

I'm gathering supplies/equipment to establish a NMEA 2000 network, for a garmin steadycast. While searching, saw some items labeled "micro c". Is there a difference between them?
If it says NMEA 2000, no matter the brand, aren't they universal?

Thank You.

Never heard of Micro c. All you need is Ts Terminators and drop cables. A Starter Kit should have it all.

Thank you very much !
