System and method for transmitting high-bandwidth signals over a satellite communications system
First Claim
1. A method for communicating signals, comprising:
- splitting an optical signal having a first bit-rate format into a plurality of signals each having a bit-rate format smaller than the first bit-rate format, wherein the bit-rate formats of said plurality of signals have smaller transmission bandwidths than said first bit-rate format; and
transmitting said plurality of signals to a satellite.

Abstract
A system for communicating signals over a satellite makes more efficient use of bandwidth compared with conventional systems. In one embodiment, the system converts an optical signal having a first bit-rate format into a plurality of signals, each having a bit-rate format smaller than the first bit-rate format and thus smaller transmission bandwidths than the initial optical signal. The converted signals are then modulated and transmitted to a satellite over a predetermined frequency band. The satellite includes a first transponder having an operating bandwidth substantially equal to the transmission bandwidth of at least two of the transmitted signals, and a second transponder having an operating bandwidth sufficient to receive remaining ones of the transmitted signals. In one preferred embodiment, the higher bit-rate format signal is an OC-3 signal, the lower bit-rate format signals are OC-1/STS-1 signals, and the first and second satellite transponders have 36 MHz operating bandwidths. Given these parameters, the system communicates information using less bandwidth than is required by conventional systems.
