Introduction

This solution allows to package optical signals, reducing the space required for switching the optical signal (Optical Space Switching), from an input port to an output port, with a higher transmission speed, lower power consumption and a higher productivity. The optical interconnection system is effectively able to reduce the space required for the transfer of signals, packing a large amount of data into smaller and more easily manageable packets. These packets are made on the basis of some characteristic physical quantities and using different multiplexing methods, and are then transferred within the interconnection network from an incoming port to an outgoing one where they are decoded and returned in their original form.

Technical features

The various types of multiplexing that can be selected are defined Mode (mode), Wavelength (wavelength), Space and Time Multiplexing, and can be associated in a variable way to obtain an interconnection network with multiple alternative routes, or more precisely multiple domains. , up to a maximum of four, while the solutions available today cannot multiply using only all 4 modes at the same time. Furthermore, the system exploits different modes of propagation, wavelength and / or other physical quantities characteristic of the optical signal, in an optical transmission medium (for example an optical fiber or an optical waveguide) as an additional domain for transport and exchange information.

Possible Applications

• Quantum computers and high performance computers (HPC): for the exchange of information between processors or between processor and memory;
• Data center: for the exchange of information between servers or between racks of servers;
• Network switches and routers: for exchanging packets (eg IP, Ethernet packets) between the different ports and / or cards of the router or switch.

Advantages

• Higher transmission speed and yields;
• Lower energy consumption: less laser + wider WDM (relaxation limits on optical components) consumption reduction;
• High band density thanks to the possibility of multiplexing optical signals on 2 or 3 different domains;
• Smallest footprint.
