Abstract

Subcarrier-multiplexed (SCM) optical links combine high-speed digital and analog signals onto an optical carrier.¹ Figure 1 shows how multiple antenna feeds could be distributed over a wavelength-division-multiplex (WDM) based system. At each port an optoelectronic (OE) switch selects the particular feed. Multiple users receive the full spectrum of signals simultaneously and can by way of the OE selector switch monitor a single desired feed.
