FIELD: optical networks.
SUBSTANCE: method and device (10a) for regeneration of optical signals with one or several means (1a,1b,1c), which may regenerate one of several various optical signals (DB3,DB4,DC1,DC2,DC3,DC4), received by device (10a), while device contains means (12) for determining quality of received optical signals (DB3,DB4,DC1,DC2,DC3,DC4), and means (1a,1b,1c) for regeneration of signals only regenerate predetermined number of signals (DC1, DB4), for which worst quality has been determined by device (12) for determining quality.
EFFECT: decreased production costs, decreased dimensions.
