OPTICAL POWER EQUALIZER FOR PASSIVE OPTICAL NETWORK

摘要

PROBLEM TO BE SOLVED: To provide an optical power equalizer capable of equalizing the optical power of optical signals in a passive optical network.

SOLUTION: A device capable of equalizing the optical power of optical signals in the passive optical network comprises: a first optical coupler for receiving optical signals having different optical power levels; an optical circulator capable of directing the optical signals from the first optical circulator; a laser diode capable of generating equalized optical signals having a predetermined range of optical power levels in response to the optical signals directed from the optical circulator, and a second optical coupler for receiving the equalized optical signals.
