| description | To easily change the number of routes, and reduce the size of wavelength selective switches without increasing the number of wavelength selective switches used.SOLUTION: An optical cross connect device includes a route group 210 including an OXC portion 220 having more than the number of connected routes, the OXC portion 220 includes an N-side port having two or more pairs of ports including a pair of ports for transmission and reception in a route, an M-side port that has two or more pairs of ports for transmission and reception, and a wavelength selection switch that realizes any one of or both a first wavelength selective switch function that outputs an optical signal input from the N side port to any port of the M side port, and a second wavelength selective switch function that outputs an optical signal input from the M side port to any port of the N side port.SELECTED DRAWING: Figure 7
【課題】容易に方路数を変更することができるとともに、使用される波長選択スイッチを増やすことなく、波長選択スイッチの規模を小さくすること。【解決手段】接続される方路の数以上のＯＸＣ部２２０を含む方路グループ２１０を備え、ＯＸＣ部２２０は、方路における送信用及び受信用の１対のポートを含む２対以上のポートを備えるＮ側ポートと、送信用及び受信用の１対のポートを２対以上備えるＭ側ポートと、Ｎ側ポートから入力された光信号をＭ側ポートの何れかのポートから出力する第１の波長選択スイッチ機能、及び、Ｍ側ポートから入力された光信号をＮ側ポートの何れかのポートから出力する第２の波長選択スイッチ機能、の何れか一方、又は、両方を実現する波長選択スイッチとを備える。【選択図】図７ |
