Ruckus 40G-QSFP-C-00501 40 Gbps Direct Attach Cable QSFP QSFP Passive Twinax

Overview

The Ruckus 40G-QSFP-C-00501 is a passive direct-attach twinax cable engineered for 40 GbE (40GBASE-CR4) links between QSFP+ ports. Designed for high-density rack-mount or data-centre switch interconnects, this cable provides a cost-effective, high-bandwidth copper path with zero transceivers required. It supports full 40 Gbps aggregate data rate (4×10 Gb channels) and is ideal for adjacent-rack or same-rack high-speed uplinks or switch stacking.Because it’s passive twinax, it consumes negligible additional power, adds minimal latency, and simplifies inventory compared to optics + fiber. Deployment is straightforward: plug the QSFP+ ends into compatible ports, secure the cable routing, and you have a high-throughput link ready for servers, aggregation or spine/leaf switches. If you’re building a dense 40G fabric and have switch chassis with QSFP+ uplinks, this cable gets you there with minimal complexity and predictable operations.

Key Features

• Supports full 40 Gb/s (40GBASE-CR4) via QSFP+ to QSFP+ twinax copper link. 

• Passive twinax construction: no active components, lower cost, lower power, ideal for short-reach rack-row links.

• Fixed length (0.5 m / ~1.6 ft) optimized for high-density same-rack connections, reducing slack and improving performance. 

• QSFP+ MSA-compliant connectors and memory map support, ensuring compatibility with Ruckus/Brocade platforms and enabling status monitoring.
