Claims (3)
- 光ファイバ、OLT及びONUを備えるバス式光ネットワークシステムであって、
前記光ファイバは、アップストリームチャネルである送信バスと、ダウンストリームチャネルである受信バスと、を有し、前記送信バス及び前記受信バスのそれぞれはTDMA技術により多重アクセスを行い、
前記OLTは、最も近いONUに接続され、トラフィック制御機能を備えたOLTNと、最も遠く離れたONUに接続されたOLTFと、を含み、
前記ONUは、前記送信バス及び前記受信バスに接続され、FTTHネットワークと、ユーザのプライベートネットワークとの間のインタフェースとして用い、前記ONUそれぞれのMACプロトコルは、前記送信バスの周波数帯域にアクセスする際のトラフィック制御機能を有することを特徴とするバス式光ネットワークシステム。 - 前記FTTHネットワークの前記プライベートネットワークは、CPEを含み、
前記CPE及びそのインタフェースは、前記ONUに直接接続されているか、無線ネットワーク、同軸ネットワーク又はLANを介して前記ONUに接続されていることを特徴とする請求項1に記載のバス式光ネットワークシステム。 - 前記ONUのそれぞれの最大トラフィック量が制限されているため、許容最大トラフィック量を前記ONUそれぞれのトラフィック制御パラメータとして用い、
前記パラメータは、前記最大トラフィック量に応じて柔軟に変動可能であり、前記受信バスから前記ONUのそれぞれに送られるトラフィック量を前記OLTN のトラフィック制御パラメータとみなし、前記最大トラフィック量に応じて各ONUへの伝送を柔軟に変えることを特徴とする請求項1に記載のバス式光ネットワークシステム。
