Abstract

The invention relates to a procedure and an arrangement for two-way transmission over a common fiber, more exact an architecture to, in a common transmission fiber, create a division of traffic channels in two-way transmission with common amplification. Traffic is routed through a connection (1) with channels with a plurality of nodes, which each has an optical amplifier (2). According to the invention, a first channel group (5) coming in in one direction at one side of each amplifier is routed to the input of the amplifier, and a second channel group (6), which is coming in in opposite direction at the other side of each amplifier, also to the input of the amplifier. The traffic from the output of the amplifier is divided so that the first channel group (5) is routed further at the other side of the amplifier (2) in one direction of the connection (1), and the second channel group (6) is routed further along the connection (1) in opposite direction. The invention can be used to increase the capacity of fiber optical links and also to effect protection switching of ring networks.
