Abstract
Fiber optic based analog and/or digital CATV systems experience composite second order distortion (CSO) caused by the interaction between the gain tilt of the doped fiber amplifier and the laser chirp due to modulation. The gain tilt for an analog/digital transmission system using a high power Er-Yb co-doped fiber amplifier has been experimentally measured and its contribution to the CSO of the transmission system is evaluated. The results are in good agreement when compared with the direct measurement of the CSO of the system with and without the amplifier. The dependence of the gain tilt on the input light modulation frequency and the input light wavelength is also investigated.
