7135LB Series

7135LB series devices, optimized for 25G speed, leverages the programmable FPGA integrated with L1 connectivity, helping customers taking their network to the next level. Available in the 1RU form factor with 48 x SFP28 ports and 4 x QSFP ports 7135LB is multiple devices in one; performing layer 1+ switching in only 5ns at 25G speed, enabling customers to upgrade their network with no impact to the latency.

The Arista 7135LB Series supports the L and LB development standard optimized for Arista’s network applications and can be leveraged to run 3rd party partner applications. FPGA application developers can utilize the platform to deploy and deliver their performance critical apps. On top of the market-leading FPGA functionality, the devices combine a multitude of Layer 1+ network functionality on to the same devices:

  • Signal regeneration
  • Port mirroring
  • Dynamic patching/link management
  • Ad-hoc tapping without rewiring
  • Layer 1+ statistics on every link
  • Media conversion
  • Telemetry and more

The devices provide Layer 1+ configurable features such as dynamic patching, tapping, one-to-many replication, media conversion, packet stats and precise timestamping. The also include the following functionality:

  • 7ns layer 1 switching between front panel ports
  • 2.5ns latency from front panel to FPGA
  • Various specifications for RAM and Transceivers
  • Development toolkits and low-latency IP Cores

7132LB Series


Robust Switches with Comprehensive Feature Sets

Feature Description
Simplified stack Fan-out with 5ns of latency, equivalent to a single metre of fiber or copper interconnect, and insignificant jitter.
Integrated with existing FPGA tools Reduce costs by converting between different Ethernet media types e.g. one end of a link can be twinax and the other 10GBASE-LR single-mode fiber.
Layer 1+ functionality Save rack space and reduce complexity by leveraging dynamic patching, tapping, one-to-many replication, telemetry and comprehensive port statistics on a single device.
Feature rich Avoid the need to build features in-house by leveraging Arista’s access control, syslog, SNMP, packet stats, tcpdump, JSON RPC API, time series data, streaming telemetry and more - included as standard within the 7130 Series.
Easy app deployment Streamline operational processes through Arista’s built-in application infrastructure which allows developers to wrap applications into simple packages for deployment.
Enterprise ready Deploy FPGA applications with ease - the FPGA platform integrates with a 64-bit x86 management processor and the MOS or EOS Operating system to provide user extensible solutions.
Ultra-low latency Fan-out with 5ns of latency, equivalent to a single metre of fiber or copper interconnect, and aggregate in 39ns.
