<title>DWDM field trial: optical performance monitoring in a transparent and configurable multiclient metropolitan network</title>

Abstract

In this paper we present the topology of an optically transparent DWDM network testbed (part of the KomNet fieldtrial). We show results of our investigation on performance monitoring in the optical layer of this complex network. The testbed consists of a remotely configurable DWDM metropolitan area ring network (capable of transport up to 80x10 Gb/s) with two OADMs and one HUB/OXC and a long-haul bi-directional DWDM link (16x10 Gb/s, 8 spans over 750 km).
