## Summary description

CBO QSFP28-DAC-2M is a 2‑metre passive copper Direct Attach Cable (DAC) designed for QSFP28 ports. It provides a short‑reach, low‑latency connection between QSFP28‑equipped switches, routers or NICs without optical transceivers. Suited for 100GbE links in data centers and server racks, it offers straightforward plug‑and‑play installation and power‑efficient operation.

## Long description

CBO QSFP28-DAC-2M is a 2-metre passive copper Direct Attach Cable engineered for QSFP28 ports. The cable delivers a short-reach, low-latency 100GbE connection between devices equipped with QSFP28 interfaces, such as switches, routers and network interface cards (NICs). As a passive copper solution, it eliminates the need for separate optical transceivers and supports plug-and-play installation in densely packed data center and server rack environments while keeping power consumption minimal.
Advantages
The passive copper design offers low latency and reliable signal transmission for short-distance 100GbE links. Its 2 m length provides flexibility for inter-rack and intra-rack connections without excess slack. Being a Direct Attach Cable reduces component count and operational power compared with optical transceivers, simplifying cabling and maintenance. The QSFP28 form factor ensures compatibility with standard QSFP28 ports and supports a straightforward plug-and-play deployment.
Suitable for
Short-reach 100 Gigabit Ethernet links in data centers
Connections between QSFP28-equipped switches, routers and NICs
Server-to-switch or switch-to-switch links inside racks
Low-latency high-throughput links in HPC or virtualization environments
Key specifications
Form factor: QSFP28 Direct Attach Cable (DAC)
Length: 2 metres
Cable type: Passive copper twinax
Supported data rate: 100 Gigabit Ethernet (100GbE)
Connector type: QSFP28 on both ends
Typical use: Short-reach links within racks or between adjacent racks
How to use
Install the CBO QSFP28-DAC-2M by inserting each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked. Ensure connectors are fully seated and the cable is routed to avoid sharp bends or excessive strain. The cable is designed for hot-plug use; devices will typically recognise the connection automatically and negotiate the 100GbE link. No additional transceivers or fibre patching are required.
Usage recommendations
For reliable operation, maintain bend radii recommended by the manufacturer and avoid running the cable near sources of strong electromagnetic interference. Use the 2 m passive DAC for short, high-bandwidth connections inside racks or between adjacent racks; for longer distances or mixed-media environments consider active optical solutions. Periodically inspect connectors for dust or damage and reseat if link issues occur.
