摘要：

Transmissions of a 6-GHz 8-phase phase-shift-keyed (8 phi -PSK) signal over a 12. 5-km single-mode fiber with a 5-dB power margin and bit-error-rate (BER) of 10** minus **1**0 and a 6-GHz 16-ary quadrature-amplitude-modulated (QAM) signal over the same distance with a 2-dB power margin and BER of 10** minus **1**2 were demonstrated. The 8 phi -PSK digital modem operated at 78 Mb/s and the 16-QAM digital modem operated at 90 Mb/s. A high-speed multimode InGaAsP laser diode and a high-speed p-i-n diode were used in both fiber-optic transmission systems. Floor characteristics and power penalties observed in the BER performances of both systems were found to be caused by the intensity noise of the laser diode, particularly the reflection-induced intensity noise. 25 refs.
