Arista DCS-7130-48LBAS-F | 7130L 48-Port 10G SFP+ FPGA Switch, Atomic Clock

Q: What is the purpose of the atomic clock in this model?
A: The integrated Rubidium atomic clock provides superior holdover accuracy and enables timestamp precision of ±75 picoseconds when synchronized via PPS input. This is critical for financial trading applications requiring precise timestamping and time synchronization across multiple devices.

Q: What applications is the DCS-7130-48LBAS-F designed for?
A: This switch is optimized for ultra-low latency applications including high-frequency trading, network tap aggregation with timestamping, packet capture and monitoring, FPGA-based network processing, and custom application development requiring sub-10ns latency and picosecond-level time precision.

Q: Can I develop custom FPGA applications on this platform?
A: Yes, the DCS-7130-48LBAS-F supports full custom FPGA development using Arista development toolkits and IP cores. The Xilinx VU9P-3 FPGA is user-programmable and Arista provides application frameworks, standard APIs, and remote JTAG programming capabilities for deploying custom network applications.

Q: What does the -F suffix indicate in the model number?
A: The -F suffix indicates front-to-rear airflow configuration with 2x AC power supplies included. This model ships ready to deploy without requiring separate PSU/Fan kit purchases, unlike the base model (DCS-7130-48LBAS#) which requires separate power supply ordering.

Q: What is the difference between the LB and LBAS models?
A: The LBAS model includes an integrated atomic clock (Rubidium oscillator) for superior timing precision and holdover performance, while the LB model uses a standard OCXO clock. The atomic clock enables ±75 picosecond timestamp accuracy when synchronized via PPS, making the LBAS ideal for applications requiring the highest timing precision.
