Abstract
The provision of quintuple-play services along wavelength division multiplexed (WDM) long-reach passive optical networks (LR-PONs) employing an ultra-bendable fiber in last-mile distribution is demonstrated experimentally. Particularly, the simultaneous transmission of three 100-GHz-spaced optical channels for the provision of double sideband orthogonal frequency-division multiplexing (OFDM) wireless and wired quintuple-play services to the premises of users located at 75, 85, and 100 km away from the central office is demonstrated. The OFDM-WDM LR-PON is tested considering the last-mile fiber distribution suffering from severe bending conditions without optical dispersion compensation. The experiments are performed for a worst last-mile fiber bending case emulated by considering a Corningr ClearCurver fiber experiencing 20 bends and a bend radius of 7.5 mm. All the OFDM signals received at the premises of users present error vector magnitude (EVM) levels compliant with the EVM thresholds of the corresponding standards. An EVM degradation in the OFDM signals received by each user not exceeding 0.8 dB due to the last-mile distribution fiber is achieved.
