BlueOptics QSFP28-DAC-1M-SS InfiniBand/fibre optic cable 1m Male/Male

The BlueOptics QSFP28-DAC-1M-SS InfiniBand/fibre optic cable 1m Male/Male is a 1-metre direct attach cable with QSFP28 connectors designed for high-speed interconnects in data center and enterprise networking environments. It supports QSFP28 interfaces used for 100 Gigabit connections and offers a compact, low-latency physical link between compatible switches, servers and network adapters. The cable is suitable for short-reach connections where high throughput and signal integrity are required.

Advantages

This QSFP28 direct attach cable provides a simple, fixed-length connection that eliminates the need for separate transceivers, reducing power consumption and component count. With a Male/Male QSFP28 interface and a one-metre length, it supports reliable high-bandwidth transfers while minimising signal loss over short distances. The cable is engineered to maintain electrical performance and low latency, making it appropriate for latency-sensitive applications and dense rack deployments.

Suitable for

• Short-reach 100 Gigabit links between switches and routers
• Server-to-switch high-speed interconnects in racks
• InfiniBand fabrics and HPC cluster connections requiring QSFP28
• Data centre top-of-rack and middle-of-row cabling

Key specifications

• Connector type: QSFP28 Male to QSFP28 Male
• Cable length: 1 metre
• Function: Direct attach cable for electrical high-speed links
• Supported link class: 100 Gigabit (QSFP28)
• Usage range: short-reach interconnects within racks or between adjacent racks
• Form factor: compact DAC assembly for dense installations

How to use

Ensure both devices support QSFP28 direct attach connections before installation. Power down or follow hot-plug guidelines of your equipment as recommended by the device manufacturer. Align each QSFP28 plug with the corresponding port and insert until the connector latches securely. After connection, verify link status and negotiated speed on both endpoints through network management tools or device LEDs. If removing the cable, release the latch mechanism and pull straight out to avoid damage to the connector or port.

Recommendations

Use this 1 m QSFP28 DAC for short, high-bandwidth links inside racks or between adjacent racks. Avoid excessive bending or pulling; maintain the minimum bend radius specified by the device vendor. Confirm compatibility with your switch and adapter vendor documentation to ensure proper operation and supported link speeds.
