被動式光網路系統

Abstract

本發明係揭露一種被動式光網路系統，包含複數訊號提供端，其係分別對應複數第一訊號接收端，並分別產生載有一下傳訊號之一第一光訊號。每一第一訊號接收端依序透過一分光器與一光濾波器接收第一光訊號，且擷取對應之訊號提供端所產生之第一光訊號，又輸出其餘第一光訊號。另有二光濾波器連接第一訊號接收端與複數第三光耦合器，以接收第一光訊號，並據此輸出不同波長之複數第二光訊號。每一第三光耦合器分別接收每一第二光訊號，以傳送至對應之第二訊號接收端。本發明於第一訊號接收端後建立新架構，具有高度發展性與經濟性。 A passive optical network system is disclosed, which comprises a plurality of signal providers respectively corresponding to a plurality of first signal receivers and respectively generating a plurality of first optical signals each carrying a downstream signal. Each first signal receiver receives the first optical signals through a power splitter and an optical filter, retrieves the first optical signal generated by the corresponding signal provider, and sends out the other first optical signals. Two optical filters connect with the first signal receivers and a plurality of third optical couplers to receive the first optical signals, thereby sending out a plurality of second optical signals of different wavelengths. Each third optical coupler receives the second optical signal to transmit it to the corresponding second signal receiver. The present invention builds a new architecture connecting the first signal receivers and has high developing and economical properties.
