A system for converting a first and a second signal representative of payload and supervisory information, respectively, between an electrical format (PL, S) and a WDM optical format, includes: a first converter (L 1 , P 1 ) for converting the first signal between the electrical format (P, L) and a first disaggregated optical format, a second converter (L 2 , P 2 ) for converting the second signal between the electrical format (S) and a second disaggregated optical format, and an optical WDM converter (WDM-C, WDM-S) for converting the first and second signals between the aforesaid first and second disaggregated optical formats and the WDM aggregated optical format. The first converter (L 1 , P 1 ), the second converter (L 2 , P 2 ) and the optical WDM converter (WDM-C, WDM-S) are integrated to a single self-contained module (TM 1 , RM 1 ). The arrangement is adapted to be implemented as a transmitter, a receiver as well as a transceiver module.
