## Summary description

CBO DAC cable QSFP28 SC282801L1M30 is a 1-meter direct-attach copper (DAC) cable designed for QSFP28 ports. It provides a short-reach, low-latency connection suitable for high-speed networking equipment, switches and servers supporting QSFP28 interfaces. The fixed-length copper assembly offers reliable electrical signalling for rack-to-rack or intra-rack links, simplified installation and lower power compared with optical transceivers.

## Long description

CBO DAC cable QSFP28 SC282801L1M30 is a 1-meter direct-attach copper (DAC) cable for QSFP28 ports, engineered for short-reach, high-speed links. The fixed-length copper assembly connects QSFP28-capable switches, network adapters and servers with a low-latency electrical interface. Designed for rack-to-rack or intra-rack connections, this cable removes the need for separate transceivers while providing a cost-effective and power-efficient alternative to optical links.
Advantages
The direct-attach copper design delivers low latency and predictable signal integrity for high-throughput environments. A 1 m length minimizes cable slack and improves airflow in dense racks. The pre-terminated QSFP28 connectors simplify installation and reduce configuration time compared with separate transceiver and patch-cord assemblies. Using copper eliminates the need for optical transceivers and associated power consumption, providing an economical option for short-distance interconnects.
Suitable for
 Short-reach connections between QSFP28 ports in the same rack or adjacent racks
 High-performance computing clusters and dense data center top-of-rack networking
 Switch-to-server and switch-to-switch links requiring 100Gb/s electrical interfaces
 Environments where low latency and low power consumption are priorities
Key specifications
 Connector type: QSFP28 to QSFP28 direct-attach copper
 Cable length: 1 m
 Transmission: electrical (copper) for short-reach links
 Data rate: supports 100Gb/s class QSFP28 interfaces
 Form factor: fixed-length, pre-terminated assembly
 Application: rack-to-rack and intra-rack interconnects
How to use
Install the DAC cable by inserting each QSFP28 connector into the corresponding port until the latch engages. Confirm link status on connected devices and ensure ports are configured for the expected speed and lane mapping. Because the assembly is fixed-length and pre-terminated, no additional transceiver modules or patch cords are required. Route the cable to avoid sharp bends and maintain recommended bend radius for copper assemblies to preserve signal integrity.
Usage recommendations
Use this 1 m direct-attach copper cable for short-distance QSFP28 interconnects inside racks or between adjacent racks. Verify compatibility with the host hardware QSFP28 port specifications and firmware recommendations before deployment. For longer distances or fiber-based redundancy, consider optical solutions instead of DAC copper assemblies.
