| 摘要 |
The present invention relates to a subsea data communication interface unit (11) for enabling data communication over a subsea data transmission line (18, 18a). The subsea data communication interface unit (11) comprises at least an electrical interface (20) for providing an electrical connection to the subsea data transmission line (18, 18a) and a transmitter (14) adapted to generate a data signal corresponding to the data to be transmitted. To obtain stable, robust and reliable communication, it is proposed that the subsea data communication interface unit (11) comprises a first voltage amplifier (24) connected between the transmitter (14) and the electrical interface (20), wherein the first voltage amplifier (24) is configured to convert the data signal generated by the transmitter (14) from a lower voltage signal (S-low) to a higher voltage signal (S-high). |
