C. Tai et al., 8-WAY, 70-KM TRANSMISSION OF 33-CHANNEL 64-QAM SIGNALS UTILIZING A 1.3-MU-M EXTERNAL MODULATION SYSTEM AND SEMICONDUCTOR OPTICAL AMPLIFIER, IEEE photonics technology letters, 8(9), 1996, pp. 1246-1248
By using a 1.3-mu m external modulation system and a semiconductor opt
ical amplifier, we experimentally demonstrated the feasibility of broa
dcasting 33 channels of 64-QAM digital CATV signals to eight 70-km opt
ical fiber links, The presented results show that, with the vast momen
tum on developing M-QAM modems, potentially low-cost semiconductor opt
ical amplifiers can possibly expedite the penetration pace of optical
fibers in broad-band access networks.
