FIELD: communication equipment.
SUBSTANCE: invention relates to communication engineering and can be used in optical communication systems. Method includes steps of displaying a signal of an optical channel unit to be transmitted, n times the reference speed on X, the first signals of the physical link of the optical channel, wherein transmission rate of optical channel physical channel first signal is equal to mi times of reference speed, adding service data of indication of line sequence to each of X first signals of physical channel of optical channel for generation of X second signals of physical channel of optical channel; and modulating and transmitting X second signals of optical channel physical line using X preset optical modules in one-to-one correspondence.
EFFECT: technical result is increased transmission channel capacity.
