Hey Guys, Probably a stupid question, but I can't find an obvious answer on Cisco. Are the following SFP's able to be used to together: One device is using at GLC-FE-100EX & the other end is using a 1000BASE-LX/LH (Single Mode fibre). I "think" these SFP's are compatible with each other.. But if someone can confirm this it would be great.
