摘要： An apparatus for performing mode scrambling in a multimode optical fibre 1 comprises an electromechanical transducer 3 and a signal generator 9. A portion of the fibre 1, which is in the form of a loop 5, is arranged with its ends 6 fixed to the transducer 3, but with the remainder of the portion being left free to vibrate. The signal generator 9 drives the transducer 3 so as to form a succession of bends of differing bend radii in the portion of the fibre as a beam of electromagnetic radiation travels through the fibre, thereby “scrambling” the beam as it travels through the fibre.

摘要： The invention relates to a method and a system for transmitting messages between a control terminal and controlled terminals for use especially in home automation installations. The controlled terminals are installed on a transmission network connected to the control terminal. The messages all have the same structure and include an originator field and a destination field. To install a new terminal a data item specific thereto is entered in the terminal. The new terminal installed transmits an installation request message including the specific data item to the terminal. In response the control terminal transmits an installation message which includes all the data needed for the installed terminal to converse with the control terminal.
