The invention relates to a three-wavelength two-way optical fiber communication system which mainly comprises an optical fiber, a transmitter optical subassembly and a receiver optical subassembly, wherein the transmitter optical subassembly comprises a first light filter, a double-wavelength laser assembly and a first light testing assembly. The double-wavelength laser assembly emits a first laser ray Lambada1 and a second laser ray Lambada2 to an optical fiber through the first light filter. The first light testing assembly receives a third laser ray Lambada3 emitted by the optical fiber through the first light filter. The receiver optical subassembly comprises a second light filter, a light receiving and emitting assembly and a second light testing assembly. The light receiving and emitting assembly emits a third laser ray Lambada3 to the optical fiber through the second light filter and receives a first laser ray Lambada1 emitted by the optical fiber through the second light filter.
