BlueOptics QSFP-40G-2M-EN-BL InfiniBand Fibre Optic Cable 2m Male/Male

The BlueOptics QSFP-40G-2M-EN-BL InfiniBand Fibre Optic Cable 2m Male/Male is a 2-metre high-speed connection designed for short-range, rack-to-rack networking in data centers and high-performance computing environments. This cable uses QSFP-to-QSFP connectivity to support up to 40 Gbps data rates and is intended for applications that require low latency and reliable signal transmission over a 2 m distance. The design follows Multi-Source Agreement (MSA) form factors and is compatible with hardware platforms that accept QSFP 40G interfaces.

Advantages

The cable provides a compact, factory-terminated solution that simplifies rack cabling and reduces installation time compared with discrete transceivers plus patch cords. As a direct-attach solution for short distances, it offers low power consumption and very low latency since it does not require active optical transceivers for the link. High-quality materials and adherence to MSA specifications ensure mechanical and electrical compatibility with a wide range of switches, routers and storage systems that support 40G QSFP links.

Suitable for

• Interconnecting switch-to-switch ports within racks or across adjacent racks
• Server to switch connections in high-performance computing clusters
• Storage system links and SAN top-of-rack connectivity
• InfiniBand and 40G Ethernet environments requiring short-range direct attach cabling

Key specifications

• Connector type: QSFP (male) to QSFP (male)
• Length: 2 metres
• Supported data rate: up to 40 Gbps
• Cable type: direct-attach (twinax/direct copper or passive InfiniBand/40G DAC form factor)
• Compliance: MSA-compliant QSFP 40G form factor
• Typical use: short-range rack connectivity with low latency and low power consumption

How to use

Install the BlueOptics QSFP-40G-2M-EN-BL by inserting each QSFP male connector into the corresponding QSFP port on your networking equipment until it engages. Ensure both endpoints are powered off or follow hot-plug procedures recommended by your hardware vendor. Verify link status through the device management interface and confirm the negotiated speed and protocol (40G Ethernet or InfiniBand) are supported by both devices. For best performance, route the cable to avoid sharp bends and minimize exposure to electromagnetic interference.

Recommendations

Use this cable for short-distance connections (up to 2 m) between compatible 40G QSFP ports. Confirm hardware compatibility with the device vendor documentation and ensure devices support passive direct-attach cabling. Avoid bending the cable beyond the manufacturer’s minimum bend radius and keep the connectors clean when making or breaking connections.
