InfiniBand-/glasvezelkabel BlueOptics P06149-B24-BL 2 m QSFP56 stekker/stekker

The BlueOptics P06149-B24-BL is a 2 m InfiniBand / fibre optic direct attach cable with QSFP56 male-to-male connectors. Designed for short-reach high-speed links, this 200G-capable cable is intended for rack and adjacent-rack connections in data centers and high-performance networking environments. The cable follows MSA guidelines for QSFP56 interconnects and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand applications that support passive DAC twinax connections.

Advantages

This 2 m QSFP56 male/male direct attach cable provides a compact, low-latency physical link for high-speed ports. As a passive twinax solution it requires no external power and offers reduced complexity compared with active optical modules for short-distance runs. The cable is manufactured using industry-standard components and MSA-compliant connector interfaces, supporting reliable mechanical and electrical mating in compatible hardware platforms.

Suitable for

• High-density switch-to-switch connections within a rack or between adjacent racks
• Direct links between servers and top-of-rack switches for storage or clustering
• Short-reach InfiniBand or 200G Ethernet links in data center aggregation layers
• Environments that require low-latency, low-power interconnects

Key specifications

• Cable type: passive twinax direct attach (DAC)
• Connector type: QSFP56 male to QSFP56 male
• Length: 2 meters
• Nominal data rate support: up to 200 Gbit/s (200GBase-CR4)
• Wire gauge: 30 AWG
• Compliance: MSA-compliant QSFP56 interface

How to use

Ensure both network devices support passive QSFP56 direct attach twinax connections and the intended transmission protocol (for example, 200GBase-CR4). Power down or follow hot-plug guidance from your hardware vendor if required, align the QSFP56 housings with the module slots and insert the connector until it latches. Verify link status and speed in the switch or host management interface. For removal, release the connector latch and pull straight out to avoid stressing the cable or port.

Recommendations

Use this 2 m passive QSFP56 DAC for short-reach connections inside racks or between adjacent racks. Avoid sharp bends and tight cable ties near the connectors, maintain proper bend radius per vendor guidance, and confirm compatibility with the hardware vendor's supported cable types to ensure proper link negotiation and performance.
