The Cassini packet transponder enables network operators to easily extend and migrate existing metro and long-haul Dense Wavelength Division Multiplexing (DWDM) networks to add new 100G capacities and extend inter-datacenter and Layer3 services.

The Cassini is a 1.5RU form factor with system throughput of 3.2Tbps based on Broadcom StrataXGS™ Tomahawk™ Plus switch silicon. The Cassini design offers sixteen fixed 100 Gigabit Ethernet QSFP28 ports, plus eight linecard slots to incorporate a flexible mix of additional 200GbE ports or DCO optical ports based on coherent DSP and optical transceivers from leading optical technology partners.

The open network switch is loaded with the Open Network Install Environment (ONIE), which supports the installation of compatible network operating system (NOS) soſtware, including the open source options Open Network Linux and other commercial NOS offerings. Cassini supports Ethernet and optical line cards with MACsec security to enable secure encrypted connections on both client-side links and metro or wide area connections.
