In designing and constructing star fiber-optic networks

optical splitter with different splitting ratios are designed conventionally according to the different losses of each optical line to distribute optical power unequally so that equal power reaches all optical nodes.However

every optical distributor is specially designed

not to be used universally

which is disadvantageous for design

production

backup and maintenance.Since the present optical receivers have fairly wide dynamic range of input power

allowing it to vary within a certain range

this paper proposes that optical star networks are rationally designed and constructed with optical equal distributor and introduces by examples the design and construction of multiple optical equal distribution networks.
