A polyimide for optical communications, having a monomer represented by the formula (1) as a repeating unit, and a method for preparing the same: Image wherein X1 and X2 are independently selected from the group consisting of halogen atom, halogenated alkyl group, halogenated aromatic ring group, -NO2, -OR1 and -SR1 (where R1 is halogenated alkyl or halogenated aromatic ring groups); and Z is selected from the group consisting of divalent halogenated aliphatic hydrocarbon, divalent halogenated aliphatic cyclic hydrocarbon and divalent halogenated aromatic hydrocarbon. Thus, light absorption loss at a near infrared light wavelength range can be minimized by using the polyimide, so that the polyimide is very useful as an optical material in the optical communications field using the light of a near infrared light region.
