Power over fiber in Raman amplified optical networks

Nowadays, the concept of passive optical networks is evolving and the powering of some elements in this kind of networks is a key issue, in order to keep the network survivability. In this work we propose the application of Raman pump remaining optical power at the receiver to be converted to electrical power. With a 24 dBm optical pump we achieve a 8 dB on/off gain over 25 km of single mode optical fiber and 27 mW of electrical power converted at the receiver.
