① The wavelength is different:

The working wavelength of the multi -mode light module is 850nm, and the working wavelength of the single -mode light module is usually 1310nm and 1550nm;

② Different transmission distance:

The farthest transmission distance of the multi -mode light module does not exceed 2km, and the transmission distance of the single -mode light module is generally above 10km;

③ The light source is different:

The multi-mode light module uses LED or VCSEL laser as a light source, and the single-mode light module is based on FD-LD laser or DFB-LD laser as a light source;

④ Different optical fiber:

Multi -mode light module with multi -mode optical fiber, single -mode light module with single -mode optical fiber;

⑤ Different application scenarios:

Many multimodal light modules of many optical module manufacturers can only be used for short -range transmission. For example: the longest transmission distance of Gigabit multi -mode light module is 550m, suitable for internal interconnection of data centers. Single -mode light modules are suitable for medium and long distances. City network transmission.
