Demonstration of a Fiber Powered Extender for PON Applications

This work proposes a new approach to powering PON extenders using the fiber powering technique, in order to make them virtually passives. In our demonstration, we show the feasibility of this technique applied to an SOA based extender for XG-PON/G-PON shared network reaching a distance of 50 km with a split ratio of 1:32. Results regarding the BER measurements and extender optical performance are discussed. This approach eliminates the batteries in the remote sites improving the reliability and the security of the system.
