Supplier Aggregation Switch OSFP

OSFP-based aggregation switches provide high-density, high-speed connectivity with up to 1.6Tbps per port, optimized for AI, ML, and hyperscale data center environments.

Overview of OSFP in Aggregation Switches

The Octal Small Form Factor Pluggable (OSFP) connector system is designed for high-speed, high-density data center applications, supporting 8- or 16-lane I/O connectivity with aggregate data rates up to 1.6Tbps per port and scalable to 3.2Tbps with stacked connectors (Molex, TE Connectivity, Amphenol). OSFP supports 56G, 112G, and 224G PAM4 signaling, providing flexibility for current and future high-speed interconnect needs while maintaining signal integrity and thermal performance .

Key Features

• High Bandwidth: Each OSFP port can handle up to 224Gbps per lane, enabling ultra-high-speed aggregation for AI, ML, and cloud workloads .
• Thermal Management: Integrated heat sinks and optimized form factor improve cooling efficiency, allowing higher-power modules without compromising reliability .
• Cable Compatibility: Supports direct-attach copper (DAC), active copper (ACC/AEC), active optical cables (AOC), and pluggable transceivers, providing flexibility in deployment .
• Backward Compatibility: OSFP connectors are backward compatible with 56G and 112G modules, simplifying upgrades and long-term scalability .
• High-Density Design: Suitable for hyperscale data centers, AI clusters, and high-performance computing environments, where space and power efficiency are critical .
