FIELD: shaping and processing radio signals.
SUBSTANCE: in order to enhance identity of copy generation while retaining ability of controlling input radio signal replication process, proposed device is provided with newly introduced (N -1) fiber-optic four-terminal networks, each of them incorporating Y-type internal adding and separating fiber-optic directional couplers.
EFFECT: reduced consumption of optical fiber.
