QDD-400G-DR4-S Cisco 400G QSFP-DD 400GBASE-DR4 SMF 500m Transceiver

The QDD-400G-DR4-S Cisco 400G QSFP-DD transceiver is typically deployed in high-density data center environments and enterprise core networks where medium-range fiber connectivity is required. It benefits network architects and engineers managing scalable infrastructures needing reliable 400G links that support virtualization, cloud services, and high-throughput applications over single-mode fiber.

How It's Used:

• Connecting spine and leaf switches in hyperscale data center fabric deployments to enable low-latency, high-bandwidth communication.
• Facilitating high-capacity inter-rack links in enterprise IT environments handling large-scale virtualization and storage traffic.
• Supporting telecom central office aggregation points requiring 400G transport over distances up to 500 meters without signal regeneration.
• Implementing scalable backbone links within campus networks that demand future-proof upgrades to 400G speeds.
• Enabling high-performance computing clusters to maintain fast data exchange with minimal footprint using QSFP-DD form factor transceivers.

This transceiver supports operational efficiency by delivering high-speed, medium-range connectivity that aligns with evolving network architectures. Its compatibility with Cisco QSFP-DD ports ensures seamless integration, helping organizations scale bandwidth capacity while maintaining manageable infrastructure complexity.
