摘要：

The effect of dispersive fibers on multichannel FM video transmission characteristics is experimentally investigated. A directly modulated 1.55-mu-m distributed feedback laser (DFB-LD) and a LiNbO3 external modulator with a CW 1.55-mu-m DFB-LD are used as optical signal sources. When the 1.3-mu-m single-mode fiber is used, directly modulated DFB-LD's suffer from second- and third-order intermodulation (IMD). The external modulator realizes good transmission characteristics irrespective of the fiber's dispersion value. This means that external modulators can realize multichannel FM television signal transmission systems that use the standard 1.3-mu-m SMF already installed in fiber optic subscriber loops.
