Detailed Specifications
Ruckus E100G-QSFP-QSFP-P-0101 100 Gb Passive Direct Attach Cable QSFP28
Overview
The Ruckus E100G-QSFP-QSFP-P-0101 is a passive twinax copper direct-attach cable (DAC) engineered for 100 Gbps links (100GBASE-CR4) between QSFP28 ports. Its fixed length of approximately 3.3 ft (1 m) fits short-reach rack-row or same-rack interconnects where fibre may not be required.Designed for high-density switching deployments, this cable plugs directly into QSFP28 ports on compatible switches—no separate transceivers needed. It is ideal for server-to-switch, switch-to-switch, or spine/leaf links in data-centre and campus aggregation environments. Because it uses passive twinax copper, power consumption and latency are minimized compared to active optics. In essence: a reliable, cost-effective 100G uplink option where reach is short and performance matters.
Key Features
Supports full 100 Gbps aggregate (4 × 25 Gb channels) over QSFP28-to-QSFP28 copper link.
Fixed 1 m (≈3.3 ft) length optimised for rack-row or adjacent rack connections
Passive twinax construction: no active electronics, lower power draw, lower latency.
Hot-plug QSFP28 compliant; plug into compatible 100G ports on data-centre switches.
Certified compatible for Ruckus/Brocade-style systems: reduces interoperability risk.
