UPSTREAM SOURCE LIGHT GENERATOR OF PASSIVE OPTICAL NETWORK SYSTEM AND METHOD OF GENERATING UPSTREAM SOURCE LIGHT

摘要

Provided is an upstream source light generator of a passive optical network (PON) system. The upstream source light generator includes an amplification part configured to amplify injection light, and a reflection part configured to receive the amplified injection light and generate reflection light by reflecting the amplified injection light with different optical delays according to wavelengths of the amplified injection light.
