Ideal for data centers and rack-to-rack links where 1 m passive copper is suitable.

## Long description

The BlueOptics DAC cable CBO QSFP28-DAC-1M is a 1-meter passive copper Direct Attach Cable with QSFP28 connectors engineered for 100G links. It provides a plug-and-play electrical interconnect for short-reach connections between switches, routers and servers without the need for separate optical transceivers. The cable is suitable for rack-to-rack and intra-rack deployments where latency, power consumption and cost are important considerations.
Advantages
The passive copper construction delivers low latency and minimal power consumption compared with active or optical alternatives. With QSFP28 connectivity and support for 100G data rates, the cable offers a straightforward, low-cost solution for high-density network environments. Its fixed 1 m length simplifies cable management in dense racks and reduces the need for additional transceiver inventory.
Suitable for
 Short-reach 100G connections between top-of-rack or leaf switches
 Direct server-to-switch links within the same rack
 Rack-to-rack interconnects in data center pods
 High-density patching in aggregation and spine layers
Key specifications
 Connector type: QSFP28 to QSFP28
 Length: 1 meter (fixed)
 Media: Passive copper twinax
 Data rate: 100 Gbit/s
 Latency: minimal, electrical direct attach
 Power: passive, no external power required
 Form factor: direct attach cable for short-reach links
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on network devices until the latch engages. Verify link status on the connected devices and ensure firmware or port settings match the 100G configuration required by your network. The cable does not require separate transceivers or additional power. For removal, depress the connector latch and pull straight out to avoid damaging the port.
Usage recommendations
Use this 1 m passive DAC for connections within a rack or between adjacent racks where 1-meter reach and low latency are sufficient. Avoid tight bends and excessive strain on the cable; maintain manufacturer-recommended bend radius and secure the cable to prevent mechanical stress on QSFP28 ports. Confirm device compatibility with QSFP28 passive DACs and check port settings for 100G operation before deployment.
