Core Switch QSFP Solution

QSFP-based core switches provide high-speed, high-density connectivity for data centers, supporting 40G to 400G per port with flexible deployment and scalability.

Overview of QSFP Switches

QSFP (Quad Small Form-factor Pluggable) switches are designed for high-bandwidth, low-latency networking, making them ideal for core and aggregation layers in data centers. They convert electrical signals into optical signals, enabling data transfer rates from 40 Gbps up to 400 Gbps per port, with multi-channel architecture allowing parallel data streams for increased throughput and efficiency . QSFP switches are compatible with both multi-mode and single-mode fibers, supporting short- and long-distance connections .

Key Features

• High Port Density: QSFP switches can host multiple high-speed ports in a compact form factor, reducing the need for additional switches and saving rack space .
• Flexible Transceiver Support: Compatible with QSFP+, QSFP28, QSFP56, QSFP-DD, and OSFP modules, allowing upgrades from 40G to 400G or beyond .
• Low Latency and High Throughput: Ideal for AI/ML workloads, cloud data centers, and high-performance computing, with support for RoCEv2 and EVPN multi-homing .
• Scalability: Breakout options allow a single QSFP port to split into multiple lower-speed connections (e.g., 1 x 400G → 4 x 100G), enabling flexible network design .
• Operational Efficiency: Hot-swappable modules reduce downtime during maintenance or upgrades, and built-in telemetry provides real-time network monitoring .

Deployment Scenarios

• Core Layer: QSFP switches serve as spine or aggregation switches, connecting multiple leaf switches and servers with high-speed uplinks .
• Data Center Spine-Leaf Architecture: Supports dense 100G or 400G uplinks for leaf switches, enabling scalable and high-performance network fabrics .
• Enterprise Aggregation: Provides high-capacity interconnects between distribution switches and core routers, reducing latency and improving throughput .

Example Solutions

• Edgecore AIS800-64D: High-performance, low-latency switch with breakout options for 400G leaf connectivity, programmable telemetry, and support for 400G QSFP-DD and future 800G OSFP modules .
• 32-Port 100G QSFP28 SONiC Switch: Enterprise-grade aggregation switch with line-rate L2/L3 throughput up to 3.2 Tbps, supporting ROCEv2 and EVPN multi-homing .
• QSFPTEK Data Center Switches: Offers a range of 10G to 800G transceivers and QSFP modules for flexible deployment in modern data centers .

Cabling and Connectivity

QSFP switches support:

• Direct Attach Copper (DAC) and Active Optical Cables (AOC) for short-range high-speed connections.
• LC-type fiber connectors for multi-mode or single-mode fiber links .
• Breakout cables to split high-speed ports into multiple lower-speed connections for flexible network design .

Benefits

• High Bandwidth: Supports modern applications requiring massive data throughput.
• Space and Cost Efficiency: Dense port configurations reduce CapEx and OpEx.
• Future-Proofing: Modular QSFP ports allow upgrades to higher speeds without replacing the entire switch.
• Enhanced Network Management: Telemetry and monitoring features enable proactive performance optimization . QSFP core switches are essential for scalable, high-performance networks, providing the flexibility, speed, and reliability required for modern data centers and enterprise environments.
