Sub wavelength Networking

Technical Introduction

Intune's implementation of sub-wavelength networking, Optical Packet Switch & Transport (OPST), is a distributed optical switch fabric technology that uses ultra fast tuning lasers to provide fully meshed, any-to-any resilient port connectivity, and is service and data format agnostic.


Every port attached to the OPST fabric has a Fast Tuneable Laser (FTL) and Burst Mode Receiver (BMR) under that port’s local control. The system assigns a unique wavelength to each BMR, so as ingress packets are queued by class of service per wavelength. The laser is tuned in real-time (nanoseconds) and multi-service frames are launched to the chosen destination via the assigned wavelength. Each port, can therefore, send and receive frames to and from all other ports providing a fully distributed switching capability with no intervening OEO between source and destination.


The OPST architecture provides unequalled and elegant linear scalability as well as operational efficiency. As new ports are individually added to the optical mesh fabric the optical paths are discovered and the logical data paths are assigned non-blocking connectivity to the new ports on the OPST meshed fabric.


Intune's product family of iVX8000 switches has the unique ability to respond dynamically to changes in network service traffic demands while maintaining guaranteed class of service commitments. Access to this dynamic infrastructure is fully programmable and available via the Restful Web Services interface.
