Ruckus E25G-SFP28-TWX-P-0301 25 Gbps SFP28 Passive Twinax Cable
Overview
The E25G-SFP28-TWX-P-0301 is a passive twinax copper direct-attach cable (DAC) designed for 25 Gbps (25GBASE-CU) links between SFP28 ports. Engineers use it for short-reach, high-bandwidth connections such as top-of-rack to aggregation switch links, adjacent-rack uplinks or stacking links within the same rack. The fixed length of ~3 metres (≈9.84 ft) makes it ideal for compact deployments where fibre isn’t needed. Because it’s passive copper, the cable needs no powered optics, reducing power consumption and complexity compared to active optics or fibre. Applicable especially for dense switch racks where multiple 25G links are required and you want minimal latency and cost. As a certified OEM accessory by Ruckus, it ensures compatibility with Ruckus/Brocade switch platforms and supports standards-compliant plug-and-play deployment.
Key Features
Full-rate 25 Gbps (25GBASE-CU) direct-attach copper link between SFP28 ports.
SFP28 ↔ SFP28 connector, fixed ~3 m length (~9.84 ft) tailored for rack-row or adjacent rack connections.
Passive twinax copper design—no active electronics, power draw negligible, ultra-low latency.
Compatible with Ruckus/Brocade (and other standards-compliant) 25G SFP28 ports—reduces interoperability risk.
Ideal for short-reach links in data centres: top-of-rack, aggregation stacks, switch interconnects.
