NEW Arista DCS-7500R-8CFPX-LC 8x 200GB Tunable Coherent DWDM Switch Line Card

The DCS-7500R-8CFPX-LC puts eight ACO-CFP2 coherent DWDM ports into an Arista 7500R chassis, so data center interconnect and metro links can run directly from the switch without separate transponders. It uses CFPX-200G-DWDM optics, tunable from 191.2 to 195.95 THz with soft-decision FEC.

Each port supports 100G PM-QPSK at over 5000 km, 150G PM-8QAM at 2000 km, or 200G PM-16QAM at 1000 km. The card is rated at 1.6 Tbps, and each port can be tuned to the wavelength assigned on the line system, so the same spare optic covers many channels.

Every port supports wire-speed 802.1AE MACsec with GCM-AES-XPN 128-bit or 256-bit encryption. MACsec requires an Arista MACsec license, sold separately (LIC-MOD-1-MACSEC).

It fits the 7504R, 7508R, 7512R and 7516R (DCS-7504, DCS-7508, DCS-7504N, DCS-7508N, DCS-7512N and DCS-7516N). System latency is under 4 microseconds at 64 bytes, and the 12 GB buffer gives about 40 ms per ingress port, useful on long-haul links. Power is 900 W typical and 1180 W maximum; the card weighs 20 lb.

A seller refurbished DCS-7500R-8CFPX-LC is also available.

Line cards and fabric modules are hot-swappable in Arista modular chassis, so you can add or replace one without powering the chassis down.

This DCS-7500R-8CFPX-LC is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
