“…The slight penalty of the drop channel at the HUB/OXC is due to the accumulation of amplified spontaneous emission in the EDFAs along the signal path. Increasing the launched channel power decreases the penalty by more than 1 dB, as demonstrated in previous lab experiments [5]. The additional decrease of receiver sensitivity at the configurable OADMs is attributed to the drop characteristic of the tunable FBGs.…”

“…An increase of the BER was detected after transmission of the selected channel through the entire DWDM metropolitan area network (rectangles, see inset and figure 6, OQM 3). The penalty of 3 dB (BER=10 -16 ) is due to EDFA noise accumulation in the ring network [5]. The penalty at BER=10 -15 is in the order of 1 dB.…”

“…This Siemens MAN consists of a bi-directional two fiber ring capable of transmitting up to 80x10 Gb/s using a 50 GHz interleaver technology [5]. The installed fibers are standard single mode fibers (SSMF) and are used by the Deutsche Telekom for real world data traffic.…”

“…Moreover, dynamic reconfiguration of a large number of DWDM channels in the optical layer (e.g. configurable 80x10 Gb/s network [5]) can result in a fast and very cost efficient reallocation of bandwidth. (ii) Optical networks support entire transparency to digital formats and bit rates of the transmitted data.…”

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).

“…The consequences of blocking include loss of revenue, reduced competitiveness, and service dissatisfaction. Recent improvements such as S-or L-band amplifiers [1], wideband fibers [6], and wavelength interleavers [7] have generated extra wavelengths, but at a considerable cost to the network operator. Alternatively, an extra degree of freedom (in addition to the wavelength) can be used to reference a channel by using other distinguishing entities (e.g., time, space, signal polarization, codes, etc.).…”

and C for the uniform line and right-angled bend, respectively, for frequencies, namely, 0.7 and 2.1 GHz.Note that as one moves away from the discontinuity, the L and C values naturally tend to those corresponding to the uniform line parameters. The variations of L and C versus frequency are consistent, as the predicted value of Z 0 ϭ ͌ L/C is 49.3°at both of the frequencies mentioned above, which, in turn, agrees well with the Z 0 plot shown in Figure 3. The glitch in L distribution that appears in the MoM solution [2] is not observed here, because it is believed to be a numerical artifact appearing in that solution. CONCLUSIONA simple, FDTD-based approach for extracting the parameters of interconnect transmission lines has been introduced. The validity of the method has been demonstrated by analyzing the right-angled bend. The method is straightforward and it enables the desired frequency characteristics to be computed in a single run. 1. J. Zhao and Z.F.

In this article, the characteristics, requirements and architectures of optical metropolitan area networks are presented. The main features of system offerings proposed for metro networks are also discussed. We outline our considerations about the evolution of metro area networks from SONET rings, to transparent wavelength‐routed WDM rings. We also describe the major transport impairments that limit the performance of transparent WDM metropolitan area networks and we present the characteristics of metro‐optimized optical amplifiers, fibers and optical add/drop multiplexers. Finally, we discuss recent research results that demonstrate that a properly engineered system utilizing application‐optimized components and fiber will enable the buildup of cost‐effective metro‐optimized WDM all‐optical networks.
