Why X2
Open architecture
Drive continuous innovation through fully programmable, software-defined switching. XISA gives you assembly-level access to programmable engines. No vendor lock-in.
Operational efficiency
Reduce infrastructure sprawl with efficient, workload-optimized switching. 40% lower power consumption than incumbent 12.8T switches. Sub-700ns latency.
Future-proof investment
Evolve your network to deliver more performance from your existing investments. UEC-ready for emerging AI networking standards.
Trusted by
Powering the world's most demanding infrastructure.
Xsight's X2 chip will form an integral part of the terabit routing needs of the next generation of Starlink satellites.”

Key features
Native 100 G SerDes
128 × 100G PAM4 LR SerDes with industry-leading reach. No retimers required for in-rack DAC connections, reducing BOM cost and latency.
X-IQ Intelligent queuing
64K queues with fine-grained per-flow scheduling. Absorb worst-case microbursts while maintaining consistent tail latency.
Fully shared packet buffer
Dynamic buffer allocation across all ports. No stranded memory; maximum utilization under variable traffic patterns.
Fast link recovery
<100 microsecond link recovery handled in microcode. Far faster than BGP convergence for rapid failover.
X-Switch architecture
X2 is built on the X-Switch parallel execution architecture. Unlike traditional match-action pipelines, X-Switch executes instructions across programmable micro-engines simultaneously, maintaining line rate without recirculation penalties.
Software and SDK
X2 integrates with industry-standard network operating systems and provides a complete development toolkit for custom implementations.
SONiC/SAI
Full SONiC and SAI integration with production-ready drivers
X-SDK
Complete toolchain including compiler, simulator, debugger
XBM
Instruction-accurate emulation for pre-silicon development
XASM
P4-like compiler support with direct XISA mapping
