Long distance transmission of 15 Gb/s digital data using subcarrier multiplexing and external modulation

摘要

This paper provides an overview of a high-speed link design using subcarrier multiplexing techniques with external modulators. Although we have few experimental results to date, we feel the techniques and technology described in this paper will enable the simultaneous transmission of multi-channel analog video and up to 15 Gb/s of digital data on a single wavelength. Furthermore, we show preliminary modeling that would indicate that at least four channels of 2.5 Gb/s can be sent over distances exceeding 500 km using a new dispersion technique that takes advantage of subcarrier multiplexing.
