## Summary description

CBO DAC Cable QSFP28 SC282801L1M30 1M is a 1‑metre direct-attach copper (DAC) cable with QSFP28 connectors, designed for 100Gbps short-reach interconnects. It provides a fixed, low-latency link between compatible network devices such as switches, routers and NICs. Ideal for data center top-of-rack and server-to-switch connections where cost-effective, power-efficient and reliable short-distance cabling is required.

## Long description

The CBO DAC cable QSFP28 SC282801L1M30 1 m is a 1-metre direct-attach copper (DAC) cable equipped with QSFP28 connectors, intended for 100 Gbps short-reach links. It offers a fixed copper connection between compatible network devices such as switches, routers and network interface cards, providing low latency and predictable performance for data centre top-of-rack and server-to-switch connections.
Advantages
This QSFP28 DAC cable delivers a cost-effective and power-efficient solution for 100 Gbps interconnects over short distances. The integrated QSFP28 connectors eliminate the need for separate transceivers and reduce component count in rack deployments. The fixed copper assembly provides stable electrical characteristics and low latency compared with active optical alternatives for equivalent short-reach applications. Installation and replacement are straightforward due to the one-piece design and standardized QSFP28 form factor.
Suitable for
 Top-of-rack switch to server 100 Gbps connections
 Switch-to-switch short-distance interconnects within racks or adjacent racks
 High-throughput server NIC connections
 High-performance compute clusters and storage arrays requiring low-latency links
Key specifications
 Connector type: QSFP28 to QSFP28 copper assembly
 Cable length: 1 metre
 Maximum data rate: 100 Gbps
 Form factor: Direct-attach copper (fixed cable, non-detachable transceivers)
 Typical application: Short-reach interconnects within racks
 Latency characteristics: Low latency, suitable for time-sensitive traffic
 Power consumption: Passive copper solution with no additional power draw for transceivers
How to use
Ensure both endpoints support QSFP28 direct-attach copper connections and are rated for 100 Gbps links. With devices powered down or with ports administratively disabled, align the QSFP28 connectors and insert the cable into each port until the latch engages. Re-enable ports and verify link status via device management interfaces or indicator LEDs. For routine troubleshooting, confirm link speed and check cable seating if the link does not come up; replace the cable if electrical continuity or performance is suspect.
Usage recommendations
Use this 1 m DAC cable for short, fixed-length connections inside racks or between adjacent racks to achieve cost- and power-efficient 100 Gbps links. Avoid sharp bends and maintain minimum bend radius specified by the manufacturer. Store and handle the cable to prevent connector contamination and inspect connectors before installation to ensure reliable contacts.
