(1) The loss of1x2 Optical splitter is not sensitive to the optical wavelength, so it can meet the transmission needs of different wavelengths. (2) The beam splitting of1x2 Optical splitter is uniform, and the signal can be evenly distributed to the user. (3) The compact structure of1x2 Optical 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 of1x2 Optical splitterhas many shunt channels, which can reach more than 32 channels. (5) The multiplex cost of1x2 Optical splitteris low, and the more the number of shunt, the more obvious the cost advantage.
