Hey there! Hope this will help you :)
The QSFP+ optical ports of CE series switches must use QSFP+ (40GE) optical modules and cables.
When a 40GE optical port works in 4*10GE mode, it can use:
- a QSFP+ optical module and MPO-4*DLC or MPO-MPO-8*FC optical fiber
- a QSFP+ to 4*SFP+ high-speed cable
- a QSFP+ to 4*SFP+ AOC cable
