Product information

Description

The BlueLan R8M59A-BL QSFP28 InfiniBand DAC Cable is a 0.5 m direct-attach copper solution engineered for short-reach, high-throughput interconnects in data center environments. Designed with QSFP28 connectors on both ends, this DAC cable supports low-latency, high-bandwidth links between InfiniBand-enabled switches, adapters and storage devices. Its black jacket and robust construction provide mechanical durability for dense rack deployments while maintaining signal integrity for demanding applications.

Advantages

This DAC cable delivers a compact, low-power physical connection that eliminates the need for transceivers and fiber transceivers for short distances, reducing cost and complexity. The QSFP28-to-QSFP28 configuration ensures straightforward plug-and-play installation and stable electrical performance. With a 0.5 m length the cable minimizes signal loss and latency for high-performance computing and storage traffic, and its durable black outer jacket improves resistance to abrasion in crowded cable runs.

Suitable for

High-performance computing clusters and InfiniBand fabrics
Direct connections between switches, routers and adapters in racks
Short-reach links in data centers and server rooms
Storage area network connections requiring low latency

Key specifications

Cable length: 0.5 m
Cable type: Direct attach copper (DAC)
Connectors: QSFP28 to QSFP28
Suitable interface: InfiniBand high-speed links
Weight: 0.15 kg
Colour: Black

How to use

Ensure both devices support QSFP28 InfiniBand connections and are powered off or in a safe state for hot-plugging according to the equipment manufacturer’s guidance. Align the QSFP28 connectors with the device ports and insert until the latch engages; confirm a secure mechanical connection. After installation, verify link status in the host or switch management interface and monitor for expected bandwidth and latency parameters. For removal, release the connector latch and gently extract the cable to avoid stressing the port.

Usage recommendations

Route the cable to avoid sharp bends and excessive tension; maintain minimum bend radius recommended by the enclosure or system vendor. Use short DAC lengths like 0.5 m for the lowest latency and best signal integrity in top-of-rack or adjacent-rack connections. Check compatibility with your InfiniBand switch or adapter firmware if link negotiation issues occur.
