## Summary description

Passive 2‑meter direct-attach copper (DAC) cable from CBO, model QSFP28-DAC-2M. Designed for QSFP28 ports, it provides a short-range, low-latency connection between switches, servers or network appliances without optical transceivers. Ideal for high-density racks and top-of-rack connections where a cost-effective, power-efficient 100GbE or compatible link is required.

## Long description

The CBO QSFP28-DAC-2M is a passive 2‑meter direct-attach copper (DAC) cable designed for QSFP28 ports. It provides a short-range, low-latency physical link for 100 Gigabit Ethernet and compatible connections without the need for optical transceivers. The cable is intended for high-density rack environments and top-of-rack connections where reduced power consumption and lower per-link cost are priorities.
Advantages
This passive DAC cable delivers low latency and low power consumption compared with active optical solutions, while offering a simple plug-and-play installation for QSFP28 interfaces. Its 2 m length suits short interconnects inside racks or between adjacent racks, enabling cost-effective 100GbE links with consistent electrical performance and minimal setup complexity.
Suitable for
Top-of-rack (ToR) switch to server connections
Switch-to-switch links within the same rack or adjacent racks
High-density data centre interconnects where space and power are constrained
Environments that require 100GbE or compatible direct copper connections without transceivers
Key specifications
Cable type: Passive direct-attach copper (DAC)
Connector format: QSFP28 to QSFP28 compatible
Length: 2 meters
Supported data rate: Designed for 100 Gigabit Ethernet and compatible standards
Use case: Short-range, intra-rack or adjacent-rack connections
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on your devices until the latch engages. Ensure both ends are fully seated and that the host devices support passive DAC links at the intended data rate. No additional transceivers, optical modules, or power sources are required for standard passive operation. When removing the cable, release the connector latch before pulling to avoid damaging the port.
Usage recommendations
Verify compatibility with your switch or server vendor's QSFP28 port firmware and supported copper cable lists before deployment. Use this 2 m passive DAC for short-distance links inside racks or between adjacent racks; for longer runs or different power/latency profiles, consider active cables or optical transceivers.
