Problems solved by technology

[0004] At present, optical modules usually use single-fiber single-wavelength transmission optical components, such as 100G QSF28 optical modules, figure 1 It is a schematic structural diagram of an existing single-fiber single-wavelength optical module, such as figure 1 As shown, the optical module requires 8 optical fibers for 4-transmit and 4-receive optical signal transmission. Therefore, the existing single-fiber single-wavelength transmission optical components cannot meet the requirements of the current network for speed and capacity, and the dense fiber channel There is a problem with crosstalk
