“…The device uses the fast gain saturation and recovery of a SOA inserted in the interferometer, effected by an externally inserted and synchronized controlling optical signal to switch bit-by-bit the state of the gate. It has been shown to be capable to operate as a 4 : 1 add-drop multiplexer on a 40 Gbit/s OTDM channel [24] with as little as 50 fJ energy per pulse [25]. Clearly the replacement of the SOA gates with the SOA-assisted Sagnac gates, will give the ability to the OXC to operate as an add-drop OTDM node for any selected wavelength channel before been forwarded to the appropriate output fibre.…”

A novel optical crossconnect architecture, capable for tens of terabit throughput and allowing the integration of wavelength and space switching, is presented for both WP and VWP networks. The architecture offers significant advantages in terms of crosstalk performance and node complexity. In the architecture, there are no crossovers and crosspoints. Therefore, the signal-to-crosstalk ratio per wavelength channel can be very high since each channel is processed independently from the others. This will also allow to introduce other all-optical techniques like adding/dropping of OTDM channels as well as optical regeneration. The proposed architecture is wavelength and link modular and particularly suitable for crossconnects with a very large number of wavelength channels. Performance aspects of a single as well as of a cascade of crossconnects have been simulated using a simulation tool.

Scalable architectures for all-optical label swapping nodes

et al. 2008

All-Optical Label Swapping (AOLS) nodes are believed to be part of the future networks. The original node designs, however, are very hard scalable. This article presents three alternatives that swap labels analogous to the original design. Two of the proposed new switches use the same all-optical technology to parallelly compare labels but, they divide fibres in data wavelengths that only transport payloads and label wavelengths that only transport labels. The third design sequentially compares the incoming label with addresses in the node available in order to make the routing decision. All three architectures are compared in terms of hardware necessary to perform routing.

“…Figure 1 shows the AOLS node-architecture proposed by the Lasagne project. The main functionalities such as label reading, label insertion and packet routing are based on the use of all-optical logic gates [8][9][10][11]. These functionalities are performed by the AOLS-block (Fig.…”

Benefits of label stripping compared to label swapping from the point of node dimensioning

et al. 2006

View full text Add to dashboard Cite

All-Optical Label Swapping (AOLS) is a promising packet-switching technology to accomplish the gap between router forwarding speed and fibre transmission speed. The hardware requirements from the node however are unarguable a big disadvantage of these kinds of nodes. In this paper, we present two alloptical label switching nodes. One is based on the MPLS technology and one is an alternative switching strategy for packet-switching: label stripping. We compare both node architectures in terms of hardware requirements for different switching strategies and network parameters (such as topology and number of nodes).
