Performance Impairments due to Gain Transients in a Raman-based Bi-directional Long-reach PON Link

A Raman-based bi-directional long-reach passive optical network (PON) link was proposed and had shown to be very robust toward WDM channel add/drops and therefore look promising for future high-capacity fiber-to-the-premises (FTTP) systems with bursty traffic. Penalty measurements on a weak data channel, under the influence of two strong neighbouring channels, being periodically added and dropped in the proposed link was reported.
