　上述のシャーシの前面カバーには、複数個の光モジュールが所定の間隔をもって一方向に並列に配置される場合がある。シャーシの前面カバーに露出した各光モジュールの端部におけるポートには、例えば、他のシステムとの相互接続を行う光ケーブル用コネクタおよび光ケーブルが接続される。各光モジュールが光モジュール用リセプタクルに接続される場合、光モジュールの接続端部が光モジュール用リセプタクル内の回路基板上に実装されるリセプタクルコネクタの被接続部に接続される。そのリセプタクルコネクタの被接続部は、上述の回路基板に電気的に接続されている。これにより、光ケーブル用コネクタおよび光ケーブルが、トランシーバモジュールを介して回路基板に電気的に接続されることとなる。 A plurality of optical modules may be arranged in parallel in one direction at a predetermined interval on the front cover of the chassis described above. For example, an optical cable connector and an optical cable for interconnection with other systems are connected to the ports at the ends of the optical modules exposed on the front cover of the chassis. When each optical module is connected to the optical module receptacle, the connection end of the optical module is connected to the connected portion of the receptacle connector mounted on the circuit board in the optical module receptacle. The connected portion of the receptacle connector is electrically connected to the circuit board described above. As a result, the optical cable connector and the optical cable are electrically connected to the circuit board via the transceiver module.
