## Summary description

CBO QSFP28-DAC-5M is a 5-meter Direct Attach Copper (DAC) cable designed for QSFP28 ports and compatible with Nokia equipment. It provides a low-latency, cost-effective copper connection for short-reach links such as server-to-switch or switch-to-switch interconnects, supporting QSFP28 form-factor high-speed interfaces. Ideal for data center and rack-level connectivity where a fixed, reliable copper link is required.

## Long description

CBO QSFP28-DAC-5M is a 5-meter Direct Attach Copper (DAC) cable designed for QSFP28 ports and compatible with Nokia QSFP28 interfaces. It provides a fixed copper connection for short-reach, high-speed links such as server-to-switch or switch-to-switch connections within data center racks. The cable supports QSFP28 form-factor electrical signaling and is intended for low-latency, cost-effective cabling where fiber transceivers are not required.
Advantages
The DAC cable offers predictable electrical performance and low latency compared with active optical alternatives for short distances. Its 5 m length simplifies rack-level cabling and reduces the need for separate transceiver modules, lowering overall link cost and power consumption. Compatibility with QSFP28 ports ensures straightforward installation in equipment designed for 100GbE or other QSFP28 electrical interfaces.
Suitable for
 Server-to-switch connectivity in data centers
 Switch-to-switch interconnects within the same rack or adjacent racks
 High-throughput, low-latency links in compute clusters
 Short-reach interconnects where cost and power efficiency are priorities
Key specifications
 Form factor: QSFP28-compatible direct-attach copper
 Length: 5 meters
 Medium: Twinax copper cable with fixed QSFP28 connectors
 Typical use: Short-reach, rack-level high-speed interconnects
 Latency: Low electrical latency appropriate for 100GbE-class links
 Power: Passive copper (no external power) or active copper as specified by vendor compatibility
How to use
Insert the QSFP28 connectors into the corresponding QSFP28 ports on each device until the connectors latch. Ensure devices are powered down or that hot-plugging is supported by the equipment manufacturer before insertion if required. After connection, verify link status in the host devices and confirm that the expected speed and lane configuration are negotiated. For best results, avoid sharp bends and mechanical strain on the cable and secure excess slack within the rack to prevent stress on the connectors.
Usage recommendations
Use this 5 m DAC cable for reliable, cost-effective rack-level connections where QSFP28 electrical interfaces are supported. Confirm compatibility with your Nokia equipment model and firmware, and follow equipment vendor guidance for hot-plugging and link configuration to ensure stable operation.
