A 10-Gb/s reconfigurable all-optical virtual private network (VPN) scheme in wavelength-division-multiplexed passive optical networks is proposed. The upstream VPN optical signal from the source optical network unit (ONU) is wavelength converted by mutual injection locking of a Fabry–Pérot laser diode at the optical line terminal to a different wavelength and then transmitted to the target ONU. The...
A 10-Gb/s reconfigurable all-optical VPN scheme in WDM-PONs based on mutually injection-locked Fabry-Pérot laser diodes is proposed and experimentally demonstrated. After 25-km fiber transmission, the power penalty at BER of 10−9 is 1.4 dB.
