Product information

Description

The BlueOptics FN-CABLE-QSFP28-2-BL is a Direct Attach Copper (DAC) cable engineered for high-speed InfiniBand and fiber-optic network links. Measuring 2 m in length and finished in black, the cable terminates in a single QSFP28 connector on one end and four QSFP28 connectors on the other, enabling compact, low-latency interconnects in racks and switch-to-server connections. It is intended for dense networking environments where reliable, short-reach, high-bandwidth links are required.

Advantages

This DAC cable provides low-latency, high-throughput data transmission suitable for InfiniBand fabrics and compatible QSFP28 ports. The fixed 2 m length reduces signal loss over short distances and simplifies cabling in racks. Its robust housings and black finish help maintain consistent mechanical connections and a tidy physical layout. The design minimizes power consumption compared with active optical alternatives while offering predictable performance in controlled environments.

Suitable for

  • Server-to-switch connections in data centers
  • High-performance computing clusters using InfiniBand
  • Top-of-rack and spine-leaf network fabrics
  • Short-reach interconnects within racks and cabinets

Key specifications

  • Cable type: Direct Attach Copper (DAC)
  • Length: 2 m
  • Connector 1: QSFP28
  • Connector 2: 4x QSFP28
  • Weight: 0.25 kg
  • Colour: Black

How to use

Install the cable by aligning the QSFP28 connector keyed features with compatible QSFP28 ports and gently inserting until the connector latches. Ensure devices are powered down or that hot-plug procedures recommended by the device manufacturer are followed. Route the 2 m cable to avoid sharp bends and reduce mechanical stress on the connectors. Verify link status on both endpoints after connection to confirm proper operation.

Usage recommendations

Use this DAC cable for short-distance, high-bandwidth links in controlled temperature environments. Avoid exposure to moisture and excessive vibration. For longer distances or environments requiring electrical isolation, consider optical transceivers and fiber cabling instead.
