## Summary description

Direct Attach Copper (DAC) cable by CBO, model 100G-QSFP-QSFP-P-00501, providing a 100G connection between QSFP28 and QSFP ports. Designed for short-reach, high-bandwidth links in data centers and network racks, it offers a low-latency, energy-efficient alternative to optical transceivers. Suitable for server-to-switch or switch-to-switch interconnects where compatible QSFP ports are available.

## Long description

The CBO DAC Cable 100G QSFP28 to QSFP (100G-QSFP-QSFP-P-00501) Direct Attach Copper provides a fixed, high-bandwidth 100 gigabit link between QSFP28 and QSFP ports. Engineered for short-reach interconnects in data centres and network racks, this passive copper assembly delivers low latency and consistent throughput without the need for optical transceivers or additional power-consuming modules. The cable supports native 100G signaling and is intended for use where compatible QSFP ports are available on servers, switches and similar networking equipment.
Advantages
This DAC cable offers a compact, low-latency connection option with predictable electrical performance over short distances. It reduces total system power consumption compared with active optical solutions, simplifies installation by eliminating transceiver pairing, and provides a cost-effective alternative for dense rack-to-rack and server-to-switch links. The fixed-assembly design ensures mechanical stability and consistent signal integrity when used within its supported reach.
Suitable for
Server-to-switch 100G links in data centre racks
Switch-to-switch aggregation or spine connections at short distances
High-bandwidth top-of-rack (ToR) interconnects where QSFP ports are present
Environments prioritising low latency and reduced power draw
Key specifications
Connector types: QSFP28 to QSFP
Nominal data rate: 100 Gbps
Cable type: Direct attach copper (DAC), fixed assembly
Target reach: short-reach links within racks or between adjacent racks
Application: server, switch and network equipment interconnects supporting QSFP
How to use
Install by inserting each QSFP connector into the corresponding QSFP or QSFP28 port until the latch engages. Ensure both endpoints support 100G over DAC and that ports are powered and configured for the intended link. Avoid excessive bending near the connector and route the cable to prevent strain on the latches. If the cable is passive, no external power or configuration is required beyond standard port setup on connected equipment.
Usage recommendations
Verify port compatibility and firmware or driver support on network devices before deployment. Observe the manufacturer’s specified maximum bend radius and maximum supported distance for reliable performance. For installations in high-interference environments or longer runs, consider active copper or optical alternatives.
