Can optical modules of different wavelengths be used interchangeably
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.
