## Summary description

CBO QSFP28-DAC-5M is a 5-meter passive copper Direct Attach Cable (DAC) designed for QSFP28 interfaces. It provides a fixed, low-latency connection between compatible networking devices, suitable for short-range links in data centers, switches and servers. The cable simplifies rack-to-rack or intra-rack connections with reliable signal integrity and plug-and-play installation.

## Long description

CBO QSFP28-DAC-5M is a 5 meter passive copper Direct Attach Cable (DAC) engineered for QSFP28 ports. It enables a fixed low-latency electrical connection between compatible QSFP28 devices, intended for short-range links within racks or between adjacent racks in data center environments. The cable is a factory-assembled, plug-and-play solution that maintains signal integrity without the need for external transceivers, simplifying installation and cabling management for switches, servers and high-performance networking equipment.
Advantages
This passive copper DAC delivers predictable latency and consistent electrical performance for short-distance interconnects. Its pre-terminated design eliminates the need for separate optics modules and reduces power consumption compared with active optical solutions. The 5 m length provides flexibility for intra-rack and near-rack topologies while preserving signal quality through controlled impedance construction. Connector housings are keyed for correct orientation and secure mating in QSFP28 ports.
Suitable for
Rack-to-rack and intra-rack high-speed connections in data centers
Direct links between QSFP28-capable switches, routers and servers
Environments where low latency and minimal power draw are priorities
Short-reach interconnects for storage and compute clusters
Key specifications
Interface: QSFP28-to-QSFP28 passive copper direct attach
Length: 5 meters
Data rate support: Designed for 100 Gbps QSFP28 applications
Cable type: Twinaxial copper with controlled impedance
Connector: QSFP28-compatible plug housings with standard latch
Installation: Plug-and-play, no additional transceivers required
Typical use range: Short-reach connections within racks or between adjacent racks
How to use
Install the cable by aligning the QSFP28 connector with the port and pressing until the latch engages; repeat for the other end. Ensure both endpoints are powered down or follow hot-swap procedures recommended by your hardware vendor if required. After seating the cable, verify link status and negotiated speed on connected devices. No additional configuration is typically necessary beyond standard port settings on switches or servers.
Usage recommendations
Use the cable for short-reach connections where 100 Gbps QSFP28 electrical interconnects are supported by both devices. Avoid tight bends and excessive strain on the cable; follow rack management best practices to maintain signal integrity. For longer distances or where galvanic isolation is needed, consider optical transceivers or active cabling alternatives.
