Fiber-to-the-Home Integration with Digital Link on Microwave Subcarrier Transport Systems

A directly modulated fiber-to-the-home (FTTH)/radio-over-fiber (ROF) transport system based on -1 side mode injection-locked and optoelectronic feedback techniques is proposed and demonstrated. Directly modulated baseband (BB) (622 Mbps) and radio frequency (RF) (622 Mbps/10 GHz) signals are successfully transmitted simultaneously over an-80 km standard single-mode fiber (SMF) transmission. Low bit error rate (BER) values and clear eye diagrams were achieved in our proposed systems. This demonstrated FTTH/ROF transport system is a promising candidate for broadband access networks.
