10 Gigabit optical transceiver refers to an optical module transceiver that can send and receive 10 Gigabit data signals per second. At present, optical modules such as XENPAK, X2, XFP, and SFP+ (small form-factor pluggable) are widely used in 10 Gigabit Ethernet. Here we will briefly introduce the 10 Gigabit SFP + optical transceiver.
