1. A system for converting a first and a second signal representative of payload and supervisory information, respectively, between an electrical format and a WDM aggregated optical format, the system including:
- at least one first converter for converting said first signal between said electrical format and a first, disaggregated optical format, at least one second converter for converting said second signal between said electrical format and a second, disaggregated optical format, and at least one optical WDM converter for converting said first and second signals between said first and second disaggregated optical formats and said WDM aggregated optical format, characterised in that said at least one first converter, said at least one second converter and said at least one optical WDM converter are integrated to a single self-contained module by means of signal propagation paths that are exempt from splices.

Abstract
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 (L1, P1) for converting the first signal between the electrical format (P, L) and a first disaggregated optical format,
- a second converter (L2, P2) 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 (L1, P1), the second converter (L2, P2) and the optical WDM converter (WDM-C, WDM-S) are integrated to a single self-contained module (TM1, RM1). The arrangement is adapted to be implemented as a transmitter, a receiver as well as a transceiver module.
