Problems solved by technology
However, the photoelectric element will generate a lot of heat when it performs photoelectric or electro-optical conversion, and the optical waveguide is generally made of non-heat-resistant materials. Therefore, the heat will easily cause the part of the optical waveguide close to the photoelectric element Deformation that affects the transmission efficiency of the optical communication device
