Real-time video streaming using ultra-wideband (UWB) technology is experimentally demonstratedalong long-reach passive optical networks (LR-PONs) with different wired and wireless reaches. Experimentaltests using external and direct modulation with UWB wireless radiation in the 10- and 60-GHz bands areperformed. An ultra-bendable fiber is also considered for a last-mile distribution. The video quality at theoutput of the optical fiber infrastructure of the LR-PON is assessed using the error vector magnitude (EVM),and the link quality indicator (LQI) is used as a figure of merit after wireless radiation. An EVM below -17dB is achieved for both externally and directly modulated LR-PONs comprising up to 125 km of optical fiber.EVM improvement is observed for longer LR-PONs when directly modulated lasers (DMLs) are used because of theamplitude gain provided by the combined effect of dispersion and DML's chirp. Compared with opticalback-to-back operation, the LQI level degrades to the maximum around 20% for LR-PONs ranging between 75 and125 km of fiber reach and with a wireless coverage of 2 m in the 10-GHz UWB band. The same level of LQIdegradation is observed using the 60-GHz UWB band with a LR-PON integrating 101 km of access network, alast-mile distribution using ultra-bendable fiber, and a 5.2-m wireless link.
