The three dominant SFP wavelength categories—850 nm, 1310 nm, and 1550 nm—are not interchangeable. Each corresponds to specific fiber types, reach classes, and application environments such as short-reach data center links, campus backbones, metropolitan aggregation, or. When it comes to the connection between two optical modules, the following four factors should be considered: wavelength, speed, fiber type, and connection to the switch. In optical communication, different wavelengths are used to transmit multiple signals simultaneously over a single fiber optic cable.
