BlueOptics QSFP30-03-BL InfiniBand Fibre Optic Cable 3m QSFP Male-Male

The BlueOptics QSFP30-03-BL InfiniBand Fibre Optic Cable 3m QSFP Male-Male is a 3‑meter high‑speed connectivity solution designed for short‑reach links in data centers and high‑performance computing environments. It features QSFP male connectors on both ends and supports InfiniBand and other 40Gb/s class applications where QSFP interfaces are used. The cable is intended for direct connections between compatible QSFP ports in switches, routers, storage arrays and compute nodes, offering a compact physical profile for rack-to-rack or in-rack interconnects.

Advantages

This 3m QSFP male-to-male cable provides a straightforward, low-latency connection suitable for high throughput requirements. Its QSFP interface ensures standardized mating with QSFP ports and supports multi-protocol traffic including InfiniBand and 40G Ethernet-compatible links. The cable’s passive design minimizes power consumption and simplifies installation and maintenance in dense rack environments.

Suitable for

• Short‑reach connections between QSFP ports in data center racks
• High‑performance computing clusters and InfiniBand fabrics
• Interconnects between switches, routers and storage hardware with QSFP support
• Upgrading or replacing existing QSFP direct‑attach links at 40G class speeds

Key specifications

• Connector type: QSFP male to QSFP male
• Cable length: 3 meters
• Supported protocols: InfiniBand and 40G-class applications (e.g., 40G Ethernet, FCoE, Fibre Channel where QSFP is supported)
• Passive direct-attach cable suitable for short-distance electrical signal transfer
• Low power consumption due to passive design

How to use

Connect each QSFP male connector to the corresponding QSFP port on the devices you intend to link. Ensure both devices support passive QSFP direct‑attach cables and the intended protocol (InfiniBand or compatible 40G application). Route the cable to avoid sharp bends and mechanical strain; secure it within the rack to prevent movement. After physical installation, verify link status and negotiate speed and protocol settings in the device management interfaces.

Recommendations

Use this cable for short-distance, high-bandwidth links inside racks or between adjacent racks. Confirm hardware compatibility and firmware settings for passive QSFP direct-attach cables before deployment. Avoid routing near heat sources and maintain bend radii consistent with QSFP connector guidelines to preserve signal integrity.
