As an optical transceiver module for 10G data transmission, the 10G connection between SFP+ optical fiber module and XFP fiber module is feasible. If the optical module on both sides of the optical fiber link have 10 gigabit speeds, if the SFP+ module is on one side and the XFP fiber module is on the other side, the XFP optical module and the SFP+optical module are compatible at the same wavelength and signal rate, you can directly connect to the communication.
