Manage Multi-Speed Ethernet Lab Connectivity in a Single Chassis
Test labs supporting equipment across multiple Ethernet speeds often rely on manual cabling or separate switching platforms for each rate, adding complexity, cost, and setup time. Keysight fixed configuration automation switches consolidate 1, 10, 25, 40, 50, 100, 200, and 400 GbE connectivity into a single Layer 1 platform with Quad Small Form-factor Pluggable 28 (QSFP-28) or QSFP Double Density (QSFP-DD) interfaces. Per-port speed and media type configuration lets engineers match each connection to the test scenario without hardware changes. The HS series scales from 32 to 512+ ports using spine-and-leaf topologies managed by Velocity Core.
1 to 400 GbE Flexibility
Support eight Ethernet speeds (1, 10, 25, 40, 50, 100, 200, and 400 GbE) in a single chassis, configurable on a per-port basis to match each test scenario.
Multi-Media Support
Connect single-mode fiber, multimode fiber, direct attach copper, and active optical cable media within the same platform, eliminating the need for separate switching fabrics.
Spine-and-Leaf Scalability
Scale from 32 to 512+ ports by linking multiple chassis in a spine-and-leaf configuration managed by Velocity Core or Velocity TestStream.
Zero-Impact Connections
Automated Layer 1 connections are deterministic and assured with zero impact on test traffic, supporting port tapping, traffic replication, and rate aggregation.

Frequently Asked Questions
Both models deliver the same multi-speed Layer 1 switching capabilities with Quad Small Form-factor Pluggable 28 (QSFP-28) and QSFP Double Density (QSFP-DD) interfaces at speeds from 1 to 400 GbE. They differ in chassis size and port density.
The HS series supports single-mode fiber, multimode fiber, direct attach copper (DAC), and active optical cable (AOC), all within a single chassis. Each port can be individually configured for speed and media type without affecting other connections.
Multiple HS series chassis can be linked in a spine-and-leaf configuration to scale from 32 to 512+ ports. Velocity Core or Velocity TestStream manages the expanded topology as a single logical fabric, giving engineers flexibility in port speeds, media types, and physical switch placement.
Yes. The HS series supports aggregation of multiple lower-speed ports to a single higher-speed port, enabling labs to use existing lower-speed test tools for higher-speed testing through rate conversion. This helps extend the useful life of existing test equipment as Ethernet speeds increase.
The HS series integrates with Velocity Core for centralized topology management, just-in-time provisioning, and secure remote access. It also works with third-party automation systems, giving teams the flexibility to incorporate the switches into existing lab infrastructure.
