InfiniBand/optický kabel BlueOptics 10323-BL 5 m QSFP samec/samec

The BlueOptics 10323-BL is a 5 m InfiniBand/fibre optic cable with QSFP male connectors on both ends, designed for short-range high-speed interconnects in racks and adjacent rack rows. It supports 40G data rates and is suitable for electrical direct-attach twinax connections that follow 40GBase-CR4 and QSFP MSA form-factor conventions. The cable is intended for reliable, low-latency links between switches, routers, storage systems and other data center hardware that accept QSFP-to-QSFP passive direct attach solutions.

Advantages

This 5 m cable provides a cost-effective connection for 40G links with low power consumption and minimal active components, resulting in reduced latency and simple, robust operation. Manufactured to MSA-compliant mechanical and electrical characteristics, it is compatible with major hardware platforms that support QSFP passive direct-attach twinax solutions. The cable construction and component selection are intended to deliver a long service life and consistent performance for short-distance high-bandwidth applications.

Suitable for

• 40G inter-switch links within the same rack or adjacent racks
• Connections between switches, routers and storage arrays supporting QSFP/QSFP
• High-throughput InfiniBand and Ethernet fabrics using 40GBase-CR4 or equivalent protocols
• Data centre top-of-rack and middle-of-row short-reach connections

Key specifications

• Length: 5 metres
• Connector type: QSFP male to QSFP male
• Data rate support: up to 40 Gbps
• Cable type: passive direct-attach twinax (copper) for short-range links
• Wire gauge: 30 AWG (typical for this cable class)
• Form factor: QSFP MSA-compliant mechanical interface

How to use

Verify that both devices support passive QSFP direct-attach twinax connections and the 40GBase-CR4 or equivalent protocol. With equipment powered down or following live-move safety procedures required by your site, align the QSFP connectors and insert the cable into the QSFP ports until the retention latch engages. After installation, power on equipment and check link status via device LEDs or management interfaces. For removal, disengage the latch and withdraw the connector straight out to avoid stressing the cable or ports.

Recommendations

For optimal performance, use this cable for short-reach connections only (such as within racks or between adjacent racks). Avoid tight bends and excessive pulling forces; maintain the cable radius recommended by the hardware vendor. Confirm vendor compatibility for passive DAC usage in your specific switch, router or storage platform to ensure full protocol and management support.
