(1) The loss of Optical fiber Splitter is not sensitive to the optical wavelength, so it can meet the transmission needs of different wavelengths. (2) The beam splitting of Optical fiber Splitter is uniform, and the signal can be evenly distributed to the user. (3) The compact structure of Optical fiber Splitter, small volume, can be directly installed in the existing various handover boxes, do not need to leave a large installation space. (4) The single component of Optical fiber Splitter has many shunt channels, which can reach more than 32 channels. (5) The multiplex cost of 1x4 box splitter is low, and the more the number of shunt, the more obvious the cost advantage.
