PURPOSE: A seed photo-generating apparatus is provided to more efficiently create the seed light used in the passive optical subscriber network. CONSTITUTION: An optical amplifier(2) creates the amplified spontaneous emission and amplifies to output. A reflective filter(1) comprises a front side back mirror, a backside reflection mirro, and collimates. The reflective receives and filters the light outputted from the optical amplifier through the optical fiber terminal. The reflective filter outputs the light of the fixed wavelet through the optical fiber terminal. The light outputted from the reflective filter is amplified through the optical amplifier and outputted to the seed light. |
