Iuron IU-CAB-QSFP/4SFP+-P0.5M 40Gbps QSFP+ to 4× SFP+ Breakout Cable

The Iuron IU-CAB-QSFP/4SFP+-P0.5M is a passive copper breakout cable assembly that bridges a single 40Gbps QSFP+ port to four independent 10Gbps SFP+ ports, enabling cost-effective bandwidth disaggregation within data centers, enterprise switching environments, and storage networks. Built to SFF-8436, SFF-8431, SFF-8432, and SFF-8472 specifications, the assembly requires no active components or external power conditioning beyond the standard 3.3V supply drawn from the host device, which simplifies deployment and reduces potential failure points. With support for up to 7 meters of reach and a per-channel data rate of 10.3125Gbps, it is well suited for rack-to-rack and shelf-to-shelf interconnects where structured cabling flexibility and density are priorities.

Key features & benefits

• 40G-to-4×10G Breakout Architecture — A single QSFP+ port is fanned out to four SFP+ connections, allowing one 40Gbps uplink to serve four independent 10Gbps downstream devices without additional switching hardware.
• Passive Copper Design — No optical components or active electronics are required along the cable path, keeping power consumption minimal and eliminating the need for dedicated transceiver modules at either end.
• Up to 7 Meter Reach — Supports transmission distances up to 7 meters, providing sufficient reach for most intra-rack and adjacent-rack interconnect scenarios in dense data center environments.
• 10.3125Gbps Per-Channel Data Rate — Each of the four lanes operates at up to 10.3125Gbps, fully supporting 10G/40 Gigabit Ethernet applications across switches, routers, and host bus adapters.
• Multi-Standard Compliance — Compliant with SFF-8436, SFF-8431, SFF-8432, and SFF-8472, as well as the latest SFP+ and QSFP MSA specifications, ensuring broad interoperability with standards-conformant equipment.
• Single 3.3V Power Supply — Operates from a nominal 3.3V supply drawn directly from the host connector, eliminating the need for external power rails or converters.
• Serial I2C Management Interface — Provides a serial I2C management interface for diagnostic and monitoring capabilities consistent with SFF-8472 digital diagnostics requirements.
• RoHS Compliant — Manufactured in accordance with RoHS directives, supporting environmental compliance programs and green procurement policies.
• Commercial Temperature Rating — Rated for operating temperatures from 0°C to +70°C and storage temperatures from -40°C to +85°C, covering standard commercial data center and enterprise environments.
