27 December 1995 Wideband analog signal transmission in all-optical networks
Author Affiliations +
A research program at The MITRE Corporation was developed to examine all-optical networks. The central element in this all-optical local area network research testbed was an optical crossbar switch employing semiconductor optical amplifiers (SOAs) as the switching and gain elements. One of the initial applications demonstrated on this all-optical testbed was the capability to transmit amplitude modulated (AM) analog signals through this network. The successful implementation of this capability demonstrates that analog imagery, telemetry, radio frequency communications, and sensor information can be distributed over a switched all-optical network. The principal challenge associated with the transmission of AM signals through the all-optical network are the limitations imposed by the SOAs in the switch. These devices exhibit non-linear transfer characteristics, have limited dynamic range, and high noise levels. This paper will describe the techniques developed to demonstrate acceptable video signal transmission performance through the all-optical switched testbed using FM modulation and microwave subcarrier technology.
