DAC kábel CBO QSFP28-DAC-1M 1 m kompatibilný s portmi Nokia QSFP28

Direct attach copper (DAC) cable CBO QSFP28-DAC-1M is a 1-meter passive copper cable compatible with Nokia QSFP28 ports. It is engineered for short-reach 100GbE connections between switches, routers and servers that use QSFP28 interfaces. The cable provides a low-latency, high-throughput physical link suitable for data center top-of-rack connections and high-density server interconnects.

Advantages

The CBO QSFP28-DAC-1M offers predictable electrical performance and low latency for 100GbE links without the power consumption and complexity of optical transceivers. As a single-cable solution, it reduces component count and simplifies installation in dense rack environments. Its fixed 1 m length is suitable for reliable short-distance connections and minimizes signal degradation compared with longer copper runs.

Suitable for

• Top-of-rack switch-to-switch 100GbE connections
• Server-to-switch high-throughput links in data centers
• Short-reach interconnects in network aggregation and spine-leaf architectures
• Test lab setups requiring reliable QSFP28 physical links

Key specifications

• Interface: QSFP28 to QSFP28 compatible with Nokia QSFP28 ports
• Cable type: Passive direct attach copper (DAC)
• Supported data rate: 100 Gigabit Ethernet
• Length: 1 meter
• Use case: Short-reach, rack-level connections
• Connector form factor: QSFP28 compliant plug

How to use

Insert each QSFP28 plug into the corresponding QSFP28 port on the devices to be connected, ensuring the latch engages and the connectors are fully seated. Verify port configuration and link negotiation on both devices; the cable is passive so no additional power or module configuration is required beyond standard port settings. For best signal integrity, route the cable with gentle bends and avoid tight kinks or sharp edges.

Recommendations

Use this 1 m DAC cable for short, rack-level 100GbE links where low latency and minimal power overhead are important. Avoid extending beyond recommended rack distances and replace the cable if the housing, latch, or conductor shows signs of damage. Ensure compatibility with your Nokia QSFP28 ports in device documentation before deployment.
