Abstract
Hybrid fiber-coax architectures have received considerable attention due to flexibility in data format and system upgradability. To support many users at the same time, optical amplifiers are essential to exploit the full capability of the architecture. With the available commercial optical amplifiers and low Rayleigh backscattering penalty, CATV operation at 1550 nm has become an active area of research. For trunk applications, externally, or directly modulated signals are first amplified and then split into different nodes at remote locations. Even though the technology for a linearized external modulator is mature, the high cost and high insertion loss of the ex-tema1 modulator makes a directly modulated system more attractive.
