Abstract: One example optical splitter chip includes a substrate. The substrate is configured with an input port, configured to receive first signal light, an uneven optical splitting unit, configured to split the first signal light into at least second signal light and third signal light, where optical power of the second signal light is different from optical power of the third signal light, a first output port, configured to output the second signal light, an even optical splitting unit group, including at least one even optical splitting unit, configured to split the third signal light into at least two channels of equal signal light, where optical power of the at least two channels of equal signal light is the same, and at least two second output ports, which are in a one-to-one correspondence with the at least two channels of equal signal light.
