## Summary description

CBO QSFP28-DAC-2M is a 2-meter passive direct-attach copper (DAC) cable with QSFP28 connectors designed for short-reach high-speed interconnects. It connects QSFP28 ports in switches, routers or servers, providing low-latency, energy-efficient links for 100GbE or compatible systems. Ideal for rack-to-rack or chassis connections where cost-effective, reliable cabling is required.

## Long description

CBO QSFP28-DAC-2M is a 2-meter passive direct-attach copper (DAC) cable with QSFP28 connectors designed for short-reach, high-speed interconnects. It provides a compact, energy-efficient physical link for 100 Gigabit Ethernet or compatible systems, enabling direct connections between QSFP28 ports in switches, routers, or servers. The cable is intended for rack-to-rack or within-chassis connections where predictable latency, low power consumption, and cost efficiency are required.
Advantages
The passive direct-attach copper design delivers low latency and minimal signal processing overhead, helping to maintain high throughput for demanding data center traffic. As a 2 meter assembly with QSFP28 connectors at both ends, the cable simplifies installation and reduces the need for transceivers. Its copper construction offers lower power consumption compared with active optical solutions for short distances and provides reliable electrical performance in structured server and switch environments.
Suitable for
 Short-reach 100GbE connections between racks or within a single rack
 Direct connections between QSFP28 ports on switches, routers, and servers
 Cost-sensitive deployments in data centers and server rooms
 Low-latency applications such as virtualization backplanes and storage networks
Key specifications
 Interface: QSFP28 to QSFP28
 Length: 2 meters
 Cable type: Passive direct-attach copper (DAC)
 Supported data rate: Designed for 100 Gigabit Ethernet or compatible high-speed links
 Connector form factor: Quad Small Form-Factor Pluggable (QSFP28)
 Typical use: Short-reach electrical interconnects within racks and between adjacent racks
How to use
Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port until the connector latches. Ensure that both devices are powered down or that hot-plug procedures recommended by the equipment manufacturer are followed. After insertion, verify link status and speed in the host devices' management interface or LED indicators. For best performance, avoid sharp bends and keep the cable routed to minimize interference with airflow and other equipment.
Usage recommendations
Use this 2 m passive QSFP28 DAC for short-distance 100GbE links where low latency and low power consumption are priorities. Confirm compatibility with your switch, router or server vendor and follow their guidance on supported passive cables. For longer distances or where electrical isolation is required, consider optical transceivers and fiber cabling instead.
