## Summary description

CBO DAC cable CBL-NTWK-0932-Q4S3M is a 3 m direct-attach copper (DAC) assembly with QSFP28 connectors supporting 100G data rates. Designed for short-reach connections between switches, routers and servers in data centers, it provides low latency, reduced power consumption and a cost-effective alternative to optical transceivers for rack-to-rack or intra-rack links.

## Long description

CBO DAC cable CBL-NTWK-0932-Q4S3M 100G QSFP28, 3 m direct-attach copper is a pre-terminated twinax copper assembly with QSFP28 connectors engineered for short-reach 100 Gigabit Ethernet links. The 3 m direct-attach copper cable is intended for high-density data center environments where low latency, low power consumption and budget efficiency are required for rack-to-rack or intra-rack connectivity between switches, routers and servers.
Advantages
The cable delivers native 100G performance over a fixed 3-meter channel while eliminating the need for separate optical transceivers and fiber patch cords. Its passive copper construction reduces power draw compared with active optical solutions and provides predictable latency and signal integrity for short distances. The QSFP28 connectors ensure compatibility with equipment supporting QSFP28 100G interfaces, enabling simple, plug-and-play installation and predictable performance in dense installations.
Suitable for
 Short-reach 100G connections between top-of-rack or spine switches
 Direct server-to-switch links in high-density racks
 Interconnects in data centers where cost-effective, low-power links are required
 Environments that prioritize minimal latency and simple cabling management
Key specifications
 Connector type: QSFP28 to QSFP28
 Cable type: Direct-attach twinax copper (DAC)
 Nominal data rate: 100 Gigabit Ethernet
 Length: 3 meters
 Construction: Passive copper assembly for short-reach links
 Typical use: Rack-to-rack and intra-rack interconnects
How to use
Insert each QSFP28 connector into compatible 100G ports on networking equipment until the latch engages. Ensure both equipment ports are powered down or follow hot-plug guidance from your hardware vendor if live insertion is supported. Verify link status via the switch or server management interface and confirm proper interface negotiation for 100G operation. For reliable operation, route the cable to avoid sharp bends and excessive strain on the connectors; maintain the manufacturer's recommended bend radius and secure the cable to prevent movement in high-flow airflow areas.
Usage recommendations
Use this direct-attach copper assembly for connections up to 3 meters where optical transceivers are not required. Avoid using the cable beyond its intended short-reach range and inspect connectors for debris before insertion. Store unused cables in a dust-free location and handle QSFP28 plugs by the housing to prevent damage to the contact interface.
