FIELD: adjustable optical amplifiers and optical transmission lines.
SUBSTANCE: proposed controllable optical amplifier designed to transfer wavelength-multiplexing signals has, respectively, first gain control device (OE1, OE2, R1) and second dominating control device (OE2, R2, R1) having much slower output power control characteristic (Pout)in compliance with basic sold power (Psold). Transmission lines equipped with such amplifiers are characterized in that both fast changes in level and slow changes in attenuation can be compensated for in them.
EFFECT: provision for maintaining reception level with changes in quantity of wavelength-multiplexing channels.
