BlueOptics 470-13411-BL InfiniBand/sklenené vlákno kábel 3 m QSFP 4xSFP+ konektor samec/konektor samec

The BlueOptics 470-13411-BL InfiniBand/fibre optic cable is a 3 m QSFP to 4xSFP+ male/male direct attach solution designed for short-reach, high-speed interconnects in racks and adjacent rack rows. Implemented as a passive twinax copper type compliant with MSA guidelines, it supports aggregated 40G links (40GBase-CR4 / 4×10GBASE-CR) and is intended for use with hardware platforms that support QSFP to 4×SFP+ direct attach connections.

Advantages

This 3-meter cable offers low latency and low power consumption typical for passive direct attach twinax solutions. Built to MSA compatibility, it is tested for interoperability with major networking hardware that supports the original form factor and signaling. The cable uses industry-standard 30 AWG conductors and provides a cost-effective option for short-distance 40G and 4×10G electrical interconnects.

Suitable for

• Interconnecting QSFP ports to multiple SFP+ ports in rack switches and servers
• Short-distance links inside and between adjacent racks (up to 3 m)
• High-speed Ethernet, FCoE and InfiniBand applications up to 40 G aggregate
• Data center top-of-rack and server-to-switch connections

Key specifications

• Cable type: passive direct attach twinax copper
• Length: 3 meters
• Connector configuration: QSFP (male) to 4×SFP+ (male)
• Supported link modes: 40GBase-CR4 and 4×10GBASE-CR (aggregated 40G)
• Wire gauge: 30 AWG
• Standards: MSA-compliant form factor and electrical signaling

How to use

Install the BlueOptics 470-13411-BL by inserting the QSFP plug into a QSFP-compatible port and each SFP+ plug into the target SFP+ ports. Ensure the connected devices support passive DAC operation and the intended transmission protocol (40GBase-CR4 or 4×10GBASE-CR). Use the 3 m length for short-reach connections inside racks or between adjacent racks; avoid stretching or sharp bends to maintain signal integrity.

Recommendations

Verify device compatibility and port settings before deployment. For environments requiring active optics or longer runs, choose appropriate fiber or active modules. Store and route the cable to avoid tight bends (minimum bend radius per manufacturer guidance) and protect connectors from contamination when not in use.
