## Summary description

CBO QSFP28 DAC cable SC282801L5M26 is a 5-meter direct-attach copper (DAC) interconnect for QSFP28 ports. Designed for short-reach high-speed connections, it provides a low-latency link between compatible switches, servers or network adapters without transceivers. Useful for data center top-of-rack or spine links, it simplifies cabling and reduces power consumption compared with optical modules.

## Long description

CBO DAC cable QSFP28 SC282801L5M26, direct-attach copper, 5 m is a 5‑metre direct-attach copper interconnect designed for QSFP28 ports. Built for short‑reach, high‑speed connections, this cable provides a low‑latency, point‑to‑point link between QSFP28‑equipped switches, servers and network adapters without the need for separate optical transceivers. The fixed copper assembly simplifies rack cabling and reduces power consumption compared with optical module solutions, making it suitable for dense data centre top‑of‑rack and spine deployments.
Advantages
The direct-attach copper design offers predictable electrical performance and low latency for 100GbE or compatible high‑speed links. Its 5 m length supports flexible rack placement while avoiding additional transceiver purchases and associated power draw. The cable is factory‑terminated for plug‑and‑play installation into QSFP28 ports, reducing deployment time and minimizing connector compatibility issues. By eliminating optical modules, it lowers operating costs and simplifies spare parts management.
Suitable for
Short‑reach 100GbE connections between top‑of‑rack switches and servers
Spine‑to‑leaf or switch‑to‑switch links in data centre fabrics
High‑density cabling environments where power efficiency is important
Environments that require plug‑and‑play direct copper links without transceivers
Key specifications
Interface type: QSFP28 to QSFP28 direct‑attach copper
Length: 5 metres
Cable medium: twinaxial copper assembly
Supported data rates: suitable for 100GbE and compatible QSFP28 speeds
Latency: low electrical latency for short‑reach links
Connector: factory‑terminated QSFP28 plugs on both ends
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on network switches, servers or adapters until the latch engages. Ensure ports are powered down or follow hot‑swap procedures recommended by the equipment vendor when inserting or removing the cable. After connection, configure the network interfaces according to your switch or server operating system to enable the desired link speed and protocols. Monitor link status via device management interfaces to confirm proper negotiation and operation.
Usage recommendations
Use this direct-attach copper cable for short interconnects within the same rack or adjacent racks. Avoid routing the cable near high‑power conductive sources or sharp bends; maintain the manufacturer’s recommended minimum bend radius. For longer distances or where optical isolation is required, consider optical transceiver solutions instead.
