Intrinsically gain-flattened Erbium-doped fiber amplifier for metro networks
Kamna Pande

This study outlines the profile optimization of a dual-core fiber, having an erbium-doped inner core that gives a relatively flat gain spectrum in the C-band, compared to conventional erbium-doped fiber amplifiers. A typical metro network has multiple add-drop nodes, and signal traffic is fluctuating. It has been demonstrated that it is possible to achieve a low-cost fiber amplifier for metro networks that can operate in a stable fashion with the dynamic nature of these networks. The fiber parameters were optimized to achieve a median gain of ~ 23 dB, with a ± 2 dB gain excursion across the C-band. © Anita Publications. All rights reserved.
