I have two Arista switches and I would like them to communicate in 1G through a direct link.
I know of three of options:
- Use copper RJ45 and SFP-to-RJ45 transceivers on both ends
- Use optical, with SFP to 1000BASE-SX transceivers
- Use optical, with SFP to 1000BASE-LX transceivers
Are there other options where there's some sort of 1G "direct attach" no requiring external transceivers?
