100G DWDM Solution
Arista’s 100G DWDM solution is a 6 x 100G Coherent DWDM line card for the 7500E series with integrated wire-speed encryption and analog coherent CFP2 optical interfaces. The line card delivers error-free performance up to 3000kms of fiber and consumes less than 140W per 100Gbps, which includes Layer 2/Layer 3 switching, wire-speed encryption and coherent DWDM. The standards-compliant coherent CFP2 optics are software tunable and support up to 96 channels in the C-band. Similar to any other Arista platform, the DWDM line card utilizes the single binary image of Arista’s extensible operating system (EOS).
Evolution of Coherent DWDM technology, along with advancements in digital signal processors with soft-decision FEC enables 100 Gbps DWDM to be integrated into a spine switch for long distance transmissions. The Arista Coherent 100G DWDM solution integrates Layer 2/Layer 3 switching with wire-speed MACsec encryption and coherent DWDM interfaces. Industry standard encryption with MACsec protects data integrity and customer confidentiality, which is critical to any organization. The use of standard pluggable coherent optics improves serviceability, and the un-bundling of optics allows for a flexible pay-as-you-grow model.
The Arista solution dramatically lowers both CapEx and OpEx for cloud data center operators compared to alternative non-integrated DWDM solutions and provides a simple, reliable and secure way to enable high bandwidth between data centers for cloud interconnect.
