Network Cable BlueOptics QSFP-40G-5M-CM-BL QSFP InfiniBand 5m Black

The BlueOptics QSFP-40G-5M-CM-BL QSFP InfiniBand 5m Black is a 5-metre high-speed network cable with QSFP connectors on both ends, designed for short-range, high-throughput links in data centres and rack environments. It is intended for reliable 40G-class connections between switches, routers, storage systems and other QSFP-capable hardware. The cable's robust build and black outer jacket support stable operation in dense rack deployments and managed cabling runs.

Advantages

This QSFP cable provides a direct attach solution for high-bandwidth interconnects with low latency and low power overhead. Its QSFP-to-QSFP terminations enable straightforward plug-and-play integration where QSFP ports are supported. The 5 m length is suitable for connections within and between adjacent racks while keeping signal integrity for short-distance, high-speed transmission. The cable's construction emphasizes durability and long service life for professional networking environments.

Suitable for

• Inter-rack and intra-rack 40G connections in data centres
• Connecting QSFP-capable switches, routers and storage arrays
• High-throughput InfiniBand or Ethernet links requiring short, direct connections

Key specifications

• Cable length: 5 m
• Connector type: QSFP to QSFP
• Intended data rate class: 40G-class links
• Application: short-range direct attach interconnects
• Colour: Black
• Weight: approximately 0.44 kg

How to use

Install the BlueOptics QSFP-40G-5M-CM-BL by inserting each QSFP connector into the corresponding QSFP port on your devices while both endpoints are powered down or according to your hardware vendor's hot-plug guidance. Ensure that connected devices support passive direct-attach QSFP links at the intended data rate. Route the cable to avoid tight bends and mechanical strain, secure it within the rack to reduce movement, and verify link status through the device management interface after connection.

Recommendations

Use this cable for short-distance, high-bandwidth links inside racks or to adjacent racks; verify compatibility with your hardware vendor for passive QSFP direct-attach cables and avoid exceeding recommended bend radii to maintain signal performance and service life.
