Detailed Specifications
Ruckus E100G-QSFP-QSFP-P-0301 100GBase Passive Twinax Direct-Attach Cable (DAC)
Overview
The Ruckus E100G-QSFP-QSFP-P-0301 is a passive twinax copper cable assembly designed for short-reach, high-density 100 GbE links in data-centre racks and aggregation fabrics. With QSFP28 (100G) connectors at both ends, it plugs directly into compatible switch or router QSFP28 ports×eliminating the need for separate transceivers, thus reducing cost, power-draw and heat in rack row installations. According to supplier info, this cable supports 100 GBASE-CR4 operation (≈103.125 Gb/s) over 3 metres of twinax cable. In practice, if you're linking adjacent racks, top-of-rack switches in the same row, or creating high-bandwidth interconnects between leaf/spine switches, this cable gives you a cost-efficient and low-latency path without fiber optics. Because it's passive, there's no active electronics, so reliability is high and failure risk low×ideal for dense rack rows where simplicity and performance matter. Use case: connecting two QSFP28 ports on leaf switches at 100G to feed server racks or uplink to spine.
Key Features
Full-rate 100 Gb/s (100GBASE-CR4) twinax cable supports high-density switch interconnect.
QSFP28 to QSFP28 connectors×plug straight into matching ports.
3 metre fixed length optimised for intra-rack or adjacent-rack cabling.
Passive copper (twinax) construction: lower cost, lower power and simpler than active optical solutions.
MSA compliant QSFP28 form-factor; vendors list compatibility with Ruckus/Brocade equipment.
