QSFP-DD Fiber Optic Hybrid Cables are high-performance, high-density interconnect solutions designed for 400G and 800G networks, offering both optical and copper connectivity with verified compatibility and reliability.

Overview

QSFP-DD (Quad Small Form-factor Pluggable Double Density) cables are designed for high-speed data center, enterprise, and service provider networks, supporting data rates up to 400G and beyond. These cables come in fiber optic, copper, and hybrid configurations, providing flexibility for short-reach and long-reach interconnects . Hybrid cables combine the advantages of active copper and optical fiber, optimizing power consumption, latency, and cost while maintaining high signal integrity .

Key Features

• High Data Rates: Supports 400G and 800G Ethernet, with some hybrid solutions reaching 1.6T per port .
• Connector Types: Uses MTP/MPO for multimode fiber, duplex LC for single-mode fiber, and QSFP-DD connectors for copper or hybrid assemblies .
• Hybrid Architecture: Combines optical and copper channels in a single cable, reducing power consumption and latency by up to 50% compared to conventional active electrical cables .
• Interoperability: Certified and tested on major network equipment from Cisco, Arista, Juniper, and Dell, ensuring reliable operation across multiple platforms .
• Standards Compliance: Compliant with IEEE 802.3bs, 400GAUI-8/CEI-56G-VSR-PAM4, and other industry standards for high-speed Ethernet .
