Abstract (en)
[origin: EP2309594A1] The system has an information transmitting unit (1) including an optical fiber unit (7) whose end embarked on a ship is fixed with laser beam emission units having a laser diode (19). Another end of the optical fiber unit is located at an altitude different from that of the ship. An electro-absorption modulator (9) modulates laser beam based on radioelectric signals. The former end of the optical fiber unit has a recovery and opto-electrical conversion unit (10) for recovery and opto-electrical conversion of the modulated part of the beam so as to retrieve the signals. The optical fiber unit is placed in a protection cable constituted of an internal protection braid made of Kevlar(RTM: para-aramid synthetic fiber).
