Arista DCS-7130-48G3S-F | 7130 Connect 48-Port 10G Layer 1 Switch, 4ns Latency

Q: What is the primary use case for the DCS-7130-48G3S-F?
A: This Layer 1 switch is designed for ultra-low latency applications including high-frequency trading, financial data centers, media broadcast, and HPC environments where 4-nanosecond deterministic latency is critical.

Q: What optics are supported on the SFP+ ports?
A: The switch supports a wide range of SFP+ optics including 1000BASE-T/SX/LX, 10GBASE-SR/LR/ER, 10GBASE-CR direct-attach copper, long-range multi-mode (LRM), and DWDM transceivers up to 80 km.

Q: How does a Layer 1 switch differ from a Layer 2 or Layer 3 switch?
A: Layer 1 switches forward data at the physical layer with full signal regeneration but no buffering or queuing, resulting in sub-nanosecond latency and zero jitter. They function as remotely configurable patch panels ideal for ultra-low latency requirements.

Q: Does the DCS-7130-48G3S-F support redundancy?
A: Yes, the switch includes 2 hot-swappable redundant AC power supplies and 2 hot-swappable redundant fan trays for high availability in mission-critical deployments.

Q: What management interfaces are available?
A: The switch offers CLI via serial console and SSH, web-based GUI, JSON-RPC, and SNMP. It runs Arista MOS (Management Operating System) based on Linux with comprehensive packet statistics and signal quality monitoring.
