## Summary description

CBO DAC cable QSFP28 SC282801L3M26 is a 3-meter direct-attach copper (DAC) assembly for 100G QSFP28 interfaces. Designed for short-reach high-speed connections between switches, servers and routers, it provides low-latency, low-power connectivity without transceivers. Ideal for data center top-of-rack links, server interconnects and high-density networking.

## Long description

BlueOptics DAC cable CBO QSFP28 SC282801L3M26 100G is a 3-meter direct-attach copper (DAC) assembly for QSFP28 interfaces, designed for short-reach high-speed connections. The cable provides a wired connection between QSFP28 ports on switches, servers and routers, delivering 100 Gigabit per second bandwidth without separate optical transceivers. Its fixed copper construction reduces power consumption and latency compared with active optics for suitable short-distance links in dense network environments.
Advantages
The DAC cable offers native 100G throughput in a single, pre-terminated assembly that eliminates the need for separate transceiver modules, simplifying installation and lowering total system cost. Its copper direct-attach design results in reduced power draw and minimal signal conversion overhead, improving energy efficiency for rack-level and top-of-rack connections. The 3 m length is optimized for short-reach interconnects in data center racks and server cabinets, and the QSFP28 connector format supports high-density deployments.
Suitable for
Top-of-rack switch to aggregation switch connections
Server-to-switch high-speed links within the same rack or adjacent racks
High-density network fabrics and leaf-spine architectures
Short-reach interconnects in data centers and server rooms
Key specifications
Interface: QSFP28 to QSFP28
Nominal data rate: 100 Gbit/s
Media: direct-attach copper (passive copper assembly)
Length: 3 m
Connector type: QSFP28 form-factor plugs
Typical use: short-reach, rack-level interconnects
How to use
Install the DAC cable by inserting each QSFP28 plug firmly into compatible QSFP28 ports on network devices until the connector latch engages. Verify port settings and link status on the connected devices; the cable requires no separate driver or module configuration in most standard QSFP28-capable switches and servers. For predictable performance, use the cable for connections within the specified length and in environments that meet the equipments operating conditions.
Usage recommendations
Route the cable to avoid tight bends and sharp edges; maintain the manufacturers minimum bend radius for copper assemblies. Use this DAC cable for short, high-bandwidth links where passive direct-attach copper is supported by your hardware to benefit from lower latency and power consumption compared with optical transceivers.
