## Summary description

Passive copper direct-attach cable (DAC) CBO QSFP28-DAC-1M, 1 meter length, QSFP28 to QSFP28. Designed for short-reach 100Gb/s connections between compatible switches, routers and network adapters using QSFP28 interfaces. Offers low-latency, low-power physical connection without transceivers, suitable for data center top-of-rack and adjacent-rack links.

## Long description

The BlueOptics DAC cable CBO QSFP28-DAC-1M is a 1 meter passive copper direct-attach cable (DAC) with QSFP28 connectors on both ends. It provides a straightforward physical link for short-reach 100Gb/s connections between devices with QSFP28 ports, eliminating the need for separate optical transceivers. This cable is intended for use in high-density networking environments where low latency, low power consumption, and cost-effective connectivity are required for top-of-rack or adjacent-rack links.
Advantages
This passive QSFP28 to QSFP28 cable delivers a compact, low-latency connection while consuming less power than active optical modules. Its fixed 1 m length reduces cable management complexity in rack environments and offers predictable electrical performance for 100Gb/s links. The integrated connectors simplify installation and reduce component count compared with solutions that require separate transceivers and fiber patch cords.
Suitable for
 Short-reach 100Gb/s connections between switches and routers with QSFP28 ports
 Top-of-rack and adjacent-rack data center interconnects
 High-density server or storage uplinks where space and power are limited
 Lab and test environments requiring reliable fixed-length copper links
Key specifications
 Connector type: QSFP28 to QSFP28
 Cable type: passive twinax copper direct-attach
 Data rate: 100 Gb/s
 Length: 1 meter
 Application: short-reach rack-level interconnects
 Latency: low, electrical direct-attach link
 Power consumption: lower than comparable optical transceiver solutions
How to use
Install the CBO QSFP28-DAC-1M by inserting each QSFP28 connector into the corresponding QSFP28 port on your network devices until the latch engages. Ensure both ends are fully seated and that devices are powered according to vendor instructions. The cable is plug-and-play for most compatible switches, routers and adapters; verify link status through device management interfaces and check firmware compatibility if required. Avoid bending the cable sharply near the connectors and route it to minimize interference and mechanical strain.
Usage recommendations
Use this passive DAC for short-distance, high-speed links within the same rack or between adjacent racks to maximize energy efficiency and reduce component complexity. Confirm QSFP28 port compatibility and firmware support on both ends before deployment. For longer distances or where optical isolation is required, consider active optical solutions instead.
