Abstract: The embodiments of the invention relate to a line switching component separable from a line card of a network node. The line switching component contains at least one input port for receiving an optical input signal from an optical transport network and at least one output port for transmitting an optical output signal to the optical transport network. The line switching component further contains at least one further output port configured to be connected to an input port of at least one optical interface of the line card and at least one further input port configured to be connected to an output port of the at least one further optical interface of the line card. The line switching component further contains a switchable optical path system configured to operate the line switching component in a first operation mode and to operate the line switching component in a second operation mode.

Abstract: Embodiments relate to an apparatus for a regenerative network node between a first and a second link portion. The apparatus comprises an input configured to receive, from the first link portion, a signal impaired by the first link portion, the signal including a data packet with a Forward Error Correction (FEC) encoded payload portion and a header portion. The apparatus comprises a signal regeneration unit configured to mitigate signal impairments of the first link portion to provide a regenerated FEC encoded payload portion. The apparatus comprises a processing unit configured to extract destination information in the data packet's header portion. If extracted destination information indicates that the data packet's destination is the regenerative network node, the data packet's regenerated FEC encoded payload portion is forwarded to a decoding unit of the regenerative network node. Else, the data packet's regenerated FEC encoded payload portion is forwarded to the second link portion.
