Optical modules are optoelectronic devices that perform photoelectric and electro-optical conversion. The transmitting end of the optical module converts electrical signals into optical signals, and the receiving end converts optical signals into electrical signals. Optical modules are classified according to the package form, and the common ones are SFP, SFP+, SFF, Gigabit Ethernet Path Interface Converter (GBIC) and so on.
