## Summary description

CBO DAC cable QSFP28 SC282801L3M26 3M is a 3-meter direct attach copper (DAC) cable with QSFP28 connectors at both ends, designed for short-range 100GbE interconnections between switches, routers, and servers. It provides a low-latency, energy-efficient link for high-speed data center applications, simplifies cabling, and is suitable for rack-to-rack and top-of-rack connections.

## Long description

The CBO DAC cable QSFP28 SC282801L3M26 3 m is a 3‑meter direct attach copper cable with QSFP28 connectors at both ends, designed for short-range 100GbE interconnections in data center environments. It creates a low-latency, energy-efficient physical link between compatible QSFP28 ports on switches, routers, and servers, and is intended for rack-to-rack and top-of-rack deployments where high throughput and simple cabling are required.
Advantages
This direct attach copper cable delivers native 100 Gigabit Ethernet throughput with minimal latency and reduced power consumption compared with active optical modules for short distances. The QSFP28 form factor ensures straightforward compatibility with QSFP28 ports, and the fixed-length design eliminates the need for transceivers and additional patching hardware, simplifying installation and lowering total cost of ownership. Its copper construction provides stable signal integrity for the specified short-range applications.
Suitable for
 Short-range 100GbE links between top-of-rack switches and aggregation switches
 Direct connections between servers and switches in the same rack or adjacent racks
 High-density data center environments requiring low-latency connectivity
 Temporary or permanent interconnects where simple, plug-and-play cabling is preferred
Key specifications
 Connector type: QSFP28 to QSFP28
 Cable type: Direct attach copper (DAC)
 Length: 3 meters
 Data rate: Supports 100 Gigabit Ethernet links
 Latency: Low-latency physical connection suitable for high-throughput applications
 Application: Short-range rack-to-rack and top-of-rack interconnects
How to use
Plug one QSFP28 connector into a compatible QSFP28 port on the network switch or router and the other connector into the corresponding QSFP28 port on the target device or server. Ensure both devices are powered down or follow hot‑swap guidance from the device vendor if the system supports hot insertion. Verify link status and interface configuration in the device management console and adjust port settings as required for 100GbE operation. Route the cable to avoid sharp bends and secure it within the rack to maintain signal integrity and airflow.
Usage recommendations
Use this direct attach copper cable for distances within rack or adjacent racks as specified; avoid using DAC cables beyond the recommended short-range limits. Confirm QSFP28 port compatibility with the device vendor and follow vendor guidelines for hot-plugging and supported link speeds. For longer distances or fiber-based infrastructure, consider using optical transceivers and fiber cabling instead.
