Abstract:
Quadrature amplitude modulation (QAM) techniques for use in optical systems are described. An optical transceiver may include a modulator configured to modulate data according to a scaled set-partitioning QAM (SP-QAM) scheme. The modulator may be configured to receive a plurality of bits, associate the plurality of bits with a plurality of symbols according to the scaled (SP-QAM) scheme; and transmit the plurality of symbols over an optical channel. A demodulator in an optical receiver may receive the plurality of symbols transmitted over the optical channel and associate the received symbols with a plurality of bits according to the scaled (SP-QAM) scheme; and provide the plurality of bits to a forward error correction decoder.

Claim (Index 8):
The optical transmitter of  claim 6 ,\n wherein points in the first set of points are arranged along a first direction and a second direction orthogonal to the first direction, and wherein the first set of points comprises a third point spaced a first distance away from the first point along the first direction, the third point having a non-zero offset relative to a corresponding point in the unscaled SP-8QAM constellation.
