We are looking into adding a 10g fiber link between two of our locations however we arent sure if its possible. We have an HP Procurve 2910al on one side and an AdTran 1638 on the other and we are looking to go between with single mode fiber.
If we get the appropriate SFP adapters for either side does it matter if one SFP adapter is Adtran and the other is HP?
Yes, this technique is used all of the time on switch to switch communication. The underlying protocol is the same. It's the Switch and SFP's job to convert to this common layer 1 protocol.
In switch to switch communication, if the switches and SFPs go in accordance with the fiber specifications, there should be no issues. Certainly, if the switch or SFPs are of low quality, then network problems occur.
