BlueOptics 100G-DACP-QSFP1M-BL InfiniBand-glasvezelkabel 1 m QSFP28 zwart

The BlueOptics 100G-DACP-QSFP1M-BL InfiniBand fibre optic cable 1 m QSFP28 Black is a 1 metre passive direct-attach cable engineered for 100G connectivity in data centre and high-performance networking environments. It uses QSFP28-compatible connectors on both ends and is intended to provide a compact, low-latency connection between InfiniBand or Ethernet ports that support QSFP28 form factor. The cable’s black jacket and slim profile are suited to dense rack installations where predictable 100 gigabit links are required.

Advantages

This fibre optic cable supports 100G data rates and is built with QSFP28-compatible male-to-male connectors to ensure straightforward plug-and-play use between compatible networking devices. Its 1 metre length minimises excess cabling in rack-mounted systems, helping to reduce clutter and maintain airflow. The passive direct-attach design offers low power consumption and stable signal transmission over short distances, making it a practical choice for server-to-switch or switch-to-switch connections within a rack or across adjacent racks.

Suitable for

• Short-reach 100G connections in data centres
• Direct connections between QSFP28 ports on switches and servers
• High-performance computing clusters using InfiniBand interconnects
• Rack-level cabling where minimal cable slack is required

Key specifications

• Connector type: QSFP28-compatible male-to-male
• Length: 1 metre
• Cable type: Passive direct-attach (DAC) for short-reach links
• Supported data rate: 100 Gigabit
• Jacket colour: Black
• Form factor: QSFP28

How to use

Verify that both network devices support QSFP28 ports and 100G passive direct-attach cables. Ensure devices are powered down or follow hot-plug guidelines from the equipment vendor before insertion. Align each QSFP28 connector with the port and insert until it seats firmly; the cable is male-to-male so no additional transceivers are required. After connection, confirm link status and configuration through device management interfaces and perform any required port configuration for 100G operation.

Recommendations

Use this 1 m DAC cable for short-distance links inside racks or between adjacent racks to maintain low latency and minimal power usage. Avoid tight bends near the connectors and route the cable to prevent strain on the plugs. For links longer than short-reach DAC specifications, select an active optical cable or appropriate fibre transceiver solution.
