What are the parameters of the optical module?

The parameters of optical module mainly include transmission rate, Center wavelength, Transmission distance, Single-mode/multi-mode, Interface type, etc.

Multimode has large loss but small dispersion during transmission, And is suitable for short-distance transmission, While single-mode has small loss but large dispersion during transmission, And is suitable for long-distance transmission.

Loss refers to the loss of optical energy caused by absorption, scattering and leakage of the medium when light is transmitted in the optical fiber. This part of the energy is dissipated at a certain rate with the increase of the transmission distance.

Dispersion occurs mainly because electromagnetic waves of different wavelengths travel at different speeds in the same medium. As a result, Different wavelength components of the optical signal reach  the receiving at different times due to the accumulation of transmission distances, Resulting in pulse broadening and inability to distinguish signal values.
