A wet mate optical connector 3 in combination with a wave division multiplexer 9, suitable for use in subsea data communications. Data is communicated from the surface to the optical connector via a plurality of optical fibres 4-7 disposed in an optical flying lead 3 and an umbilical cord, with each optical fibre transmitting electromagnetic radiation of different wavelengths. Each fibre is connected to an input side of the wave division multiplexer , which may be held within the optical connector. A single optical cable 10 on an output side of the multiplexer provides multiplexed optical signals to an interface of the connector, joined to a power and communications distribution module 11. This contains a demultiplexer 12 which demultiplexes the signal back into multiple signals with their respective wavelengths. A plurality of converters 13-16 convert each optical signal to an electrical signal, which are transmitted to respective electronic modules 17-20. The system can be used in seabed facilities for extracting hydrocarbons. |
