Multichannel selector of longitudinal fashions

А.V. Kolomitsev
Annotations languages:

The use of the synchronized single-mode multifrequency radiation of laser is offered for the multichannel passing to information on the opened line of transmissions and fiber. Requirements which are produced to the radiation of single-mode multifrequency laser is high-fidelity synchronization of longitudinal fashions and stabilizing of frequencies of the intermode beatings. On condition of the use only of one laser-transmitter and offered selector of longitudinal fashions, it is possible to provide N of informative channels, the amount of which is equal to the amount of frequencies.
Keywords: synchronized одномодовое multifrequency radiation of laser
