## Summary description

Direct attach copper (DAC) cable CBO OCTTAPCABLE3M is a 3-meter QSFP-compatible pre-terminated interconnect designed for short-reach links between QSFP ports. It provides a low-latency, power-efficient connection for switches, routers and network appliances that accept QSFP-compatible DACs, simplifying rack-to-rack or within-rack cabling without optics.

## Long description

BlueOptics CBO DAC cable OCTTAPCABLE3M is a 3 m QSFP-compatible direct attach copper (DAC) cable engineered for short-reach interconnects between QSFP ports. The pre-terminated cable connects QSFP-capable switches, routers and network appliances without the need for separate optical transceivers, offering a low-latency and power-efficient link suitable for within-rack and rack-to-rack connections. The cable’s QSFP compatibility and fixed copper construction simplify deployment and reduce component count for data centre and enterprise topologies.
Advantages
This 3 m DAC cable delivers predictable electrical performance for high-speed QSFP interfaces while minimizing power consumption compared with optical links. Being pre-terminated and QSFP-compatible, it reduces installation time and eliminates the need for separate SFP/QSFP transceivers and optics. The direct copper design provides low latency and consistent signal integrity for short-distance connections inside racks or between adjacent racks, and its fixed length helps maintain tidy cable management.
Suitable for
 Short-reach links between QSFP ports in data centre and server rack environments
 Switch-to-switch or switch-to-router connections within the same rack or between adjacent racks
 High-throughput, low-latency links for cluster and storage interconnects
Key specifications
 Cable type: Direct attach copper (DAC)
 Connector compatibility: QSFP-compatible plugs at both ends
 Length: 3 metres
 Use case: Short-reach, within-rack and adjacent rack interconnects
 Performance characteristics: Low latency, power-efficient compared with optical transceivers
How to use
Install the DAC cable by inserting the QSFP-compatible connectors into the corresponding QSFP ports on each device until the latch engages. Ensure both ports support QSFP-compatible direct attach copper links and that devices are powered and configured for the intended link speed. Route the 3 m cable to avoid sharp bends and excessive strain; secure it for proper cable management and to maintain connector seating. No separate transceivers or optics are required because the cable is pre-terminated.
Usage recommendations
Verify device compatibility with QSFP-compatible DACs before installation and choose the 3 m length for short, rack-level interconnects to achieve optimal latency and power efficiency. Avoid environmental exposure to moisture and extreme temperatures, and inspect connectors for debris before connecting.
