## Summary description

Passive copper Direct Attach Cable (DAC) by CBO, model QSFP28-DAC-2M, 2 meters long. Designed for QSFP28 ports, it provides a cost-effective short-reach connection between compatible network devices such as switches, routers, and servers. Ideal for 100GbE or passive high-speed interconnects in data centers, it simplifies cabling and reduces power consumption compared with active optical modules.

## Long description

The Copper DAC Cable CBO QSFP28-DAC-2M is a 2-metre passive direct attach cable designed for QSFP28 ports and compatible 100GbE hardware. As a copper passive solution, it provides a short-reach interconnect that links switches, routers and servers without the need for separate transceivers. The cable offers a straightforward, low-power option for high-density networking environments and is suited to data centre top-of-rack and adjacent-rack connections where distances up to two metres are required.
Advantages
This passive QSFP28 direct attach cable reduces overall system cost by eliminating the need for active optical modules and separate transceivers. Its copper construction lowers power consumption compared with active optical solutions and simplifies installation with an integrated QSFP28 connector on each end. The fixed 2 m length helps maintain cable management and supports high-density port deployments while delivering the bandwidth and signal integrity expected for 100GbE links.
Suitable for
Short-range 100 Gigabit Ethernet connections between switches, routers and servers
Top-of-rack and adjacent-rack interconnects in data centres
High-density networking racks where low latency and low power are priorities
Key specifications
Connector type: QSFP28 on both ends for direct attach use
Cable type: Passive copper direct attach cable
Length: 2 metres
Supported data rate: 100GbE (QSFP28 standard)
Typical use: Short-reach interconnects within racks or between adjacent racks
Power profile: Passive (no active components, lower power consumption than active optical solutions)
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on your networking devices until the connector latches. Ensure both devices are configured for 100GbE operation and check link status through the devices' management interfaces. Route the cable to avoid sharp bends and maintain recommended bend radius for high-speed copper assemblies. For removal, release the connector latch and withdraw straight out to avoid damaging ports.
Usage recommendations
Use this passive DAC for short, direct connections up to 2 metres inside racks or between adjacent racks. Verify device compatibility with QSFP28 passive copper direct attach cables in vendor documentation before deployment, and maintain proper cable routing and strain relief to preserve signal integrity and port longevity.
