Abstract :
By using a 1.3-μm external modulation system and a semiconductor optical amplifier, we experimentally demonstrated the feasibility of broadcasting 33 channels of 64-QAM digital CATV signals to eight 70-km optical fiber links. The presented results show that, with the vast momentum on developing M-QAM modems, potentially low-cost semiconductor optical amplifiers can possibly expedite the penetration pace of optical fibers in broad-band access networks.
