Abstract:
Methods, apparatus, and systems are provided for remoteable communication systems (Fig. 1). More particularly, the inventions of this system include a remoteable or distributed communications system having a plurality of front ends (Fig. 1, 110) located remotely from a base station. Each front end includes a receive side subsystem with an HTS filter (Fig. 1, 112), a non-linear modulator (see Fig. 1, 118), and may also include a low noise amplifier (Fig. 1, 116) coupled to the non-linear modulator (see Fig. 1, 118). The nonlinear modulator (Fig. 1, 118) modulates a RF signal in light prior to transport via an optical transmission path to the base station (Fig. 1, 160). Because the modulator is placed in the front end (Fig. 1, 118), no down conversion is required prior to transport of a received signal.
