Remote Pumping in Point to Multi-point Networks
Abstract
A remotely pumped Erbium-doped system for the amplification of an optical signal for long-reach (LR) next-generation passive optical networks (NG-PONs) is presented in this paper. The next-generation networks will be deployed with/over the current point to multi-point technology with/without backward compatibility. Remote pumping allows extending the reach of the optical distribution networks and the magnification of the splitting ratio as well, which is most important for increasing the number of end users in the PON network. In our laboratory, we have successfully verified the functionality of the unidirectional and bidirectional remote pumping system based on an Erbium-doped fiber inserted into the route and remote pumping from a central office. Our measurement results prove that it is possible to extend the total reaching point to the multi-point system without the difficult incidence in the optical distribution network. Based on the results, the proposed amplifying passive optical network approach is capable of being used in passive optical networks in C band for extending the total reach of system or increasing the split ratio.
