Iuron IU-CAB-QSFP/4SFP+-P3M QSFP+ to 4x SFP+ 40Gbps Passive Copper Cable

The Iuron IU-CAB-QSFP/4SFP+-P3M is a passive copper breakout cable assembly that bridges a single 40Gbps QSFP+ port to four independent 10Gbps SFP+ ports over a single 7-meter run. Designed to SFF-8436, SFF-8431, SFF-8432, and SFF-8472 specifications, it delivers a structured, cost-effective interconnect solution for data center and enterprise environments where high-density 10G/40G Ethernet connectivity is required between switches, routers, HBAs, and storage systems. As a fully passive assembly with no active signal conversion components, it draws only a single 3.3V supply and maintains full MSA compliance across both the QSFP+ and SFP+ interfaces. Its commercial temperature rating and RoHS compliance make it well suited for rack-to-rack and shelf-to-shelf deployments in structured cabling environments.

Key features & benefits

• 40G to 4x10G Breakout Architecture — A single QSFP+ port running at 40Gbps is split across four SFP+ lanes each operating at up to 10.3125Gbps, enabling direct fan-out connectivity without additional switching hardware.
• Fully Passive Copper Construction — No active components or signal processing chips are required, reducing power draw, latency, and potential failure points while keeping total cost of ownership low.
• Full MSA Compliance — Compliant with SFF-8436, SFF-8431, SFF-8432, and SFF-8472 specifications, ensuring interoperability with any standards-conformant QSFP+ and SFP+ port infrastructure.
• 7-Meter Reach — Supports transmission distances up to 7 meters, providing meaningful reach for rack-to-rack and shelf-to-shelf interconnects within a data center row or pod.
• Dual Management Interface — Serial and I2C management interfaces are supported, allowing host systems to query cable status and diagnostic data through standard in-band management protocols.
• RoHS Compliant — Manufactured without restricted hazardous substances, meeting RoHS requirements and supporting environmentally responsible procurement and disposal practices.
