## Long description

BlueOptics DAC cable CBO QSFP28 5 m is a passive direct-attach twinax copper assembly with QSFP28 connectors, designed for short-reach high-speed links between networking devices. At 5 meters length it provides a fixed copper connection suitable for server-to-switch and switch-to-switch interconnects where low latency and cost-effective cabling are required. The cable supports QSFP28 port interfaces and is intended for use with compatible Juniper equipment and other systems that accept passive DAC QSFP28 modules.
Advantages
This passive DAC cable delivers low latency and high electrical signal integrity over a 5 m twinax copper link without the need for optical transceivers or external power. Its QSFP28 connectors offer a compact, industry-standard interface for 100 Gigabit Ethernet or other QSFP28-supported protocols, reducing port occupancy and simplifying rack cabling. The fixed-length copper assembly is economical for short-distance runs and eliminates the need to manage separate SFP/QSFP transceivers and fiber patch cords.
Suitable for
Short-reach 100 GbE connections between servers and switches
Switch-to-switch uplinks within the same rack or adjacent racks
High-density data center top-of-rack cabling
Environments where passive, low-latency copper links are preferred over active optics
Key specifications
Connector type: QSFP28 to QSFP28
Cable type: Passive twinax (DAC) copper
Length: 5 meters
Use case: Short-reach links for high-speed networking
Compatibility: Designed for systems that accept QSFP28 passive DAC assemblies
How to use
Install the DAC cable by firmly inserting each QSFP28 connector into the corresponding port on the networking devices until the latch engages. Ensure both devices are powered off or follow hot-plugging procedures recommended by the device manufacturer. Verify link status through device management interfaces after connection. Avoid excessive bending, kinking, or pulling on the cable and route it to prevent strain on connectors and ports.
Usage recommendations
Maintain a minimum bend radius as specified by the manufacturer and avoid routing the cable near strong electromagnetic sources. For reliable operation, use this passive 5 m DAC in short-distance setups such as within racks or between adjacent racks; for longer distances consider active optical solutions. Confirm compatibility with device firmware and port settings before deployment.
