BlueOptics AA1404033-E6-BL InfiniBand/optický kabel 1 m QSFP 4xSFP+ samec/samec

The BlueOptics AA1404033-E6-BL InfiniBand/fibre optic cable is a 1 m QSFP to 4xSFP+ male/male direct attach cable designed for short-range, high-speed connections in data center and networking environments. Supporting 40GBase-CR4 and 4x10GBASE-CR signaling, this passive twinax copper assembly provides a straightforward means to link switches, servers and storage hardware that accept QSFP-to-4xSFP+ direct attach connections. The compact 1 m length is intended for rack-to-rack or within-rack use where low latency and minimal power consumption are required.

Advantages

The cable offers a passive design that eliminates the need for active transceivers, reducing power consumption and latency while simplifying installation and maintenance. Manufactured to MSA-compliant mechanical and electrical standards, its components are selected to match common data center hardware platforms and support Ethernet, Fibre Channel over Ethernet (FCoE) and InfiniBand protocols at line rates up to 40 Gbit/s over the 1 m length. The QSFP-to-4xSFP+ form factor enables flexible connectivity between 40G ports and multi-10G ports without intermediate modules.

Suitable for (tasks / use cases)

• Direct connections between QSFP and 4xSFP+ ports in rack or adjacent rack environments
• 40GBase-CR4 and 4x10GBASE-CR intra-rack links for switches and servers
• High-throughput, low-latency links for storage arrays and SAN fabrics
• Short-distance InfiniBand and Ethernet interconnects in data centers

Key specifications

• Length: 1 meter
• Connector types: QSFP (male) to 4xSFP+ (male)
• Transmission capacity: up to 40 Gbit/s aggregate (4x10G lanes)
• Cable type: passive twinax copper (30 AWG)
• Standards: MSA-compliant QSFP to SFP+ direct attach form factor
• Power consumption: passive (negligible, typically ~0.1 W system-level saving vs active solutions)
• Typical applications: Ethernet, FCoE, Fibre Channel and InfiniBand at short distances

How to use

Insert the QSFP plug into a compatible QSFP port and each SFP+ plug into the corresponding SFP+ ports on the target device. Ensure both devices support passive QSFP-to-4xSFP+ direct attach twinax cables and are configured for the intended link speeds and protocols. Avoid excessive bending near the connectors and secure the cable to prevent strain on the plugs. After physical installation, verify link status and speed via the network equipment management interface and, if necessary, adjust port configurations to enable the expected 40G or 4x10G operation.

Recommendations

Use this 1 m passive QSFP-to-4xSFP+ cable for short-distance links within racks or between adjacent racks. Confirm device compatibility with passive DACs and MSA QSFP/SFP+ form factors before deployment. For longer runs or where active signal conditioning is required, consider active optical or active copper alternatives.
