Abstract

We demonstrated the dependence of IR-UWB signal waveform on the RZ pulse width, and made it clear that optical RZ pulse width of 12.5 to 90 ps is necessary in combined 1.25 Gbps 10 km SMF and wireless link with UWB band of 7.25-10.25GHz. The 10Gbps (1.25 Gbps × 8TDM) IR signal transmission in optical fiber link is also demonstrated using 29 ps optical pulse. The system satisfies the communication quality in the wireless transmission range of 0.5 m-2.5 m.
