摘要： The invention concerns a transmitter-receiver device (A, B) which comprises a receiver unit (RXA) arranged to receive light and optical signals from a transmitter unit (TXA) arranged to transmit light and optical signals. The device also comprises a supervising unit (CUA) which prevents the transmitter unit (TXA) from continuously transmitting light when the supervising unit (CUA) detects that the receiver unit (RXA) does not receive light. The supervising unit (CUA) is arranged to, when it detects that the receiver unit (RXA) does not receive light, change to a test mode where the transmitter unit (TXA) is controlled to intermittently transmit short light pulses the supervising unit has an output ( 109 ) where a status signal indicates whether the transmitter-receiver device is in said test mode. The invention also concerns a communication system which comprising at least two such transmitter-receiver devices.

摘要： Downstream digital telephony signals are transmitted over the 1310 nm transmission band of a silica optic fiber. Upstream digital telephony signals are transmitted over a "short wavelength" portion of the 1550 nm transmission band of the optic fiber, i.e. within a portion of the 1550 nm transmission band having wavelengths less than a predetermined threshold wavelength of 1550 nm. Simultaneously, downstream analog video signals are transmitted over a "long wavelength" portion of the 1550 nm transmission band of the optic fiber, i.e. within a portion of the 1550 nm transmission band having wavelengths exceeding the predetermined threshold wavelength of 1550 nm but still within an erbium-doped fiber amplifier gain profile. Thus, the upstream digital telephony signals are always transmitted at wavelengths shorter than the threshold wavelength and the downstream analog video signals are always transmitted at wavelengths longer than the threshold wavelength. Accordingly, no significant signaling conflicts occur between the upstream digital telephony signals and the downstream analog video signals, and both upstream and downstream digital telephony signals and analog video signals are reliably carried over the single optic fiber.

摘要：自由空間通信トランシーバは、レーザビーム送受信用望遠鏡と、データで変調された送信レーザビームを発生する同調可能レーザ送信器と、望遠鏡から受け取った受信レーザビームを処理してデータを回復する同調可能受光器と、送信レーザビームを望遠鏡へ導き、望遠鏡からの受信レーザビームを受光器へ導く同調可能ビームスプリッタとを含む。送信および受信レーザビームは、望遠鏡とビームスプリッタとの間を、同一直線上の平行自由空間ビームとして共通光軸に沿って通過する。送信および受信レーザビームは、交換可能な異なる波長で動作し、それによって全二重操作を実現する。ビームスプリッタには、その波長依存の透過特性が送信および受信の波長にしたがって調節される同調可能エタロンフィルタが使用される。選択的に、さらにＲＦ信号が共通光軸に結合され、望遠鏡によって送受信されてもよい。
