DAC cable CBO 100G-QSFP-QSFP-P-0301 100G direct-attach QSFP-to-QSFP, 100 Gbps, passive, blue

CBO DAC cable 100G-QSFP-QSFP-P-0301 is a passive direct-attach copper cable with QSFP connectors on both ends that supports 100 Gbps links for short-reach interconnects. Intended for use in data center top-of-rack and server connections, the cable delivers low latency and energy-efficient connectivity with plug-and-play installation between devices equipped with QSFP ports.

Advantages

The passive DAC design provides a cost-effective, low-power alternative to active optical modules for short distances. With QSFP-to-QSFP connectivity at 100 Gbps, the cable minimizes signal conversion and reduces latency. Its fixed form factor requires no additional configuration, enabling quick deployment in dense rack environments. The blue jacket offers easy visual identification among network cabling.

Suitable for

• Short-reach connections between top-of-rack switches and servers
• Direct links between routers, switches or network interface cards with QSFP ports
• High-throughput aggregation and spine-leaf topologies in data centers
• Environments where low latency and energy efficiency are priorities

Key specifications

• Connector type: QSFP-to-QSFP
• Nominal data rate: 100 Gbps
• Passive direct-attach copper construction
• Cable color: blue
• Optimized for short-reach rack and chassis interconnects
• Plug-and-play deployment without external power source

How to use

Ensure both devices have compatible QSFP ports and support 100 Gbps operation. Power down equipment if recommended by the hardware vendor, insert one QSFP connector into each port until the latch engages, and power up devices if previously powered down. Verify link status through device LEDs or management interfaces and confirm negotiated speed and link health. For hot-pluggable setups, follow the equipment manufacturer’s guidance for safe insertion and removal.

Recommendations

Use this passive DAC for short distances within racks or between adjacent racks; avoid using it for long-span links. Maintain a gentle bend radius to prevent cable damage and route the cable to minimize strain on connectors. For environments with high electromagnetic interference or where longer reaches are required, consider using active copper DACs or optical transceivers as alternatives.
