InfiniBand/sklenené vlákno kábel BlueOptics CPAC-DAC-100G-3M 3m QSFP28 samec

The BlueOptics CPAC-DAC-100G-3M 3m QSFP28 Male is a 3-metre direct attach cable engineered for 100 Gbps InfiniBand and fibre-channel applications. It provides a short-reach copper/fibre solution with QSFP28 male terminations designed to deliver low latency and high throughput in rack-to-rack and intra-rack connections. The cable is intended for use in data centers and high-performance computing networks where stable, high-bandwidth links are required for switches, servers and storage systems.

Advantages

This QSFP28 cable supports 100 Gbps data rates with minimal signal loss and reduced latency compared with longer optical transceivers. The fixed 3 m length simplifies cabling layouts in dense equipment racks and reduces the need for additional patch panels. Robust connector housings and standardized pinouts ensure compatibility with equipment that accepts QSFP28 direct attach connections. Energy consumption is lower than active optics for equivalent short-reach links, and the cable design promotes consistent performance under continuous high-load conditions.

Suitable for

• Short-reach 100 Gbps connections between switches within a rack or adjacent racks
• Server to switch links in high-performance computing clusters
• Storage network interconnects and SAN uplinks that require low latency
• Network equipment testing and lab environments requiring reliable QSFP28 links

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 3 metres
• Rated data rate: 100 Gbps
• Cable type: direct attach (DAC) suitable for short-reach interconnects
• Use case: InfiniBand and high-speed Ethernet/fibre channel environments
• Latency: optimized for minimal latency in point-to-point links

How to use

Verify that both devices accept QSFP28 direct attach connections and are rated for 100 Gbps operation. With equipment powered down or following hot-plug guidelines from the vendor, align the QSFP28 connector with the port and insert until it seats securely. Ensure proper cable routing to avoid sharp bends and strain on the connectors; maintain the specified bend radius. After connection, check link status in the network equipment management interface and confirm negotiated speed and link health. For removal, follow vendor hot-unplug recommendations and depress the connector latch before withdrawing the plug.
