Cabo de fibra ótica InfiniBand BlueOptics CBL-NTWK-0417-01-BL 1 m QSFP ficha/ficha

The BlueOptics CBL-NTWK-0417-01-BL is a 1 m InfiniBand/fibre optic cable with QSFP male-to-male connectors designed for high-speed data transmission in data centres and high-performance computing environments. The 1 metre length and QSFP-to-QSFP interface provide a compact, low-latency connection for short-reach links between compatible switches, routers, storage systems and server adapters. The cable supports 40G applications and is suitable for use where a reliable direct connection with minimal power consumption is required.

Advantages

This QSFP male-to-male cable offers straightforward plug-and-play connectivity for devices that support QSFP interfaces and 40GBase-CR4 or InfiniBand protocols. As a short-reach direct attach solution, it provides low latency and low power consumption compared with active optical transceivers. The cable is built to MSA-compliant form factors and uses high-quality components to ensure consistent signal integrity across the 1 m link.

Suitable for

• Connecting QSFP ports in adjacent racks or within the same rack
• 40GBase-CR4, Ethernet and InfiniBand links for short distances
• High-performance computing clusters and data centre switches
• Storage systems and server interconnects requiring 40 Gbit/s links

Key specifications

• Cable type: QSFP-to-QSFP direct attach (male-to-male)
• Length: 1 metre
• Supported data rate: up to 40 Gbit/s (per cable pair as defined by supported protocols)
• Transmission medium: twinax copper direct attach for short-range electrical signalling
• Connector type: QSFP (Quad Small Form-factor Pluggable)
• Design: passive direct attach cable (no active electronics in cable)
• Wire gauge: 30 AWG (typical for Twinax DAC)

How to use

Verify that both devices (switches, routers, storage arrays or host adapters) support QSFP passive direct attach cables and the intended protocol (40GBase-CR4, Ethernet or InfiniBand). Align the QSFP connectors with the ports and insert until the retention latch engages. Avoid excessive bending of the cable near the connector ends; maintain gentle curves and do not exceed the minimum bend radius specified by your equipment manufacturer. For removal, press the connector latch and pull straight out to prevent damage to the port or plug.

Recommendations

Use this 1 m QSFP male-to-male cable for short, direct links inside racks or between adjacent racks where low latency and low power consumption are priorities. Confirm compatibility with the hardware vendor's supported cable list and run an initial link test after installation to verify signal integrity and the negotiated link speed.
