## Summary description

Direct attach copper (DAC) cable CBO QSFP28-DAC-3M, 3 meters long, designed for QSFP28 ports and compatible with Gigamon equipment. Provides a low-latency, short-reach wired connection for 100GbE setups, switches, and network appliances. Ideal for rack-to-rack links, top-of-rack connections, and high-throughput server interconnects where a cost-effective, power-efficient cable is required.

## Long description

The DAC cable CBO QSFP28-DAC-3M is a 3 meter direct attach copper (DAC) cable engineered for QSFP28 ports and compatible with Gigamon QSFP28 equipment. It provides a short-reach, low-latency wired link for 100 Gigabit Ethernet (100GbE) environments, enabling reliable rack-to-rack and top-of-rack connections. The cable is suitable for high-throughput server interconnects and network appliances where power efficiency and reduced latency are priorities.
Advantages
This 3 m DAC cable offers a cost-effective alternative to active optical cables for short distances, with lower power consumption and minimal signal latency. Its direct attach copper design ensures stable electrical performance for 100GbE links and compatibility with QSFP28 ports used in switches and network devices. The fixed length and pre-terminated connectors simplify installation and reduce the need for transceivers, lowering overall system cost and cabling complexity.
Suitable for
Rack-to-rack 100GbE connections in data centers
Top-of-rack (ToR) switch uplinks
High-throughput server interconnects
Connections between switches and network appliances compatible with QSFP28 ports
Key specifications
Connector type: QSFP28 to QSFP28 compatible with QSFP28 ports
Cable type: Direct attach copper (DAC)
Length: 3 meters
Supported data rate: 100 Gigabit Ethernet (100GbE)
Typical reach: short-reach, suitable for rack and top-of-rack deployments
Latency: low, suitable for latency-sensitive applications
Power consumption: lower than comparable active optical solutions
How to use
Install the DAC cable by inserting each QSFP28 connector into the corresponding QSFP28 port on the switch, server, or network appliance until it seats securely. Ensure both ends are connected to devices that support QSFP28 interfaces and 100GbE operation. Route the cable within the rack to avoid tight bends and mechanical strain; maintain recommended bend radius for copper DAC assemblies. After connection, verify link status and speed via device management interfaces or LEDs to confirm successful negotiation at 100GbE.
Usage recommendations
Use this DAC cable for short-distance, high-bandwidth links where low latency and energy efficiency are required. Avoid using the cable in environments with excessive vibration, extreme temperatures, or where longer distances are needed; in such cases, consider fiber or active optical alternatives. Store and handle the cable by the connector housings and avoid sharp bends to preserve signal integrity and ensure long-term reliability.
