Py. Chiang et al., 33-CHANNEL 64-QAM SIGNAL TRANSMISSION USING A 1.3-MU-M SEMICONDUCTOR OPTICAL AMPLIFIER, IEEE photonics technology letters, 8(1), 1996, pp. 119-121
From the network evolution point of view, optical amplifiers in a hybr
id fiber coaxial (HFC) system may become extensively deployed at appro
ximately the same time as when analog AM-VSB video signals are all rep
laced by digital M-QAM or M-VSB signals. This letter demonstrates the
feasibility of using a 1.3-mu m semiconductor optical amplifier to tra
nsport 33 channels of 64-QAM signals with 30 Mbps/channel. A total sys
tem power budget of 20.3 dB was obtained.
