## Summary description

CBO QSFP28-DAC-1M is a 1‑metre passive copper DAC cable designed for 100G connections between QSFP28 ports. It provides a low-latency, cost‑effective direct attach solution for short‑reach links in data centers, switches and servers. The fixed 1m length and passive design simplify installation and reduce power consumption while ensuring compatibility with QSFP28 interfaces.

## Long description

CBO DAC Cable QSFP28-DAC-1M is a 1 metre passive copper direct attach cable engineered for 100G connections between QSFP28 ports. The cable delivers a fixed, short-reach interface for interconnecting switches, servers and storage systems in data centers and server rooms. Its passive design eliminates the need for optical transceivers, reduces power consumption and provides a straightforward, low-latency physical link for high-bandwidth applications.
Advantages
The 1m passive copper construction offers low latency and predictable signal integrity across short distances, while keeping acquisition and operating costs lower than comparable optical links. A fixed-length assembly simplifies cable management and rack planning. Compatibility with QSFP28 form-factor ports makes the cable suitable for direct attach between compatible 100G devices without additional modules, and the passive design contributes to reduced heat generation and lower power draw in densely populated racks.
Suitable for
Short-reach 100G server-to-switch connections in data centers
Switch-to-switch uplinks within the same rack or adjacent racks
High-bandwidth storage system interconnects
Top-of-rack (ToR) and leaf-spine network segments requiring 100G links
Key specifications
Connector type: QSFP28 to QSFP28
Length: 1 metre fixed
Cable medium: Passive copper twinax
Nominal data rate: 100 Gbps
Application: Short-reach direct attach for intra-rack and adjacent-rack links
Power: Passive (no active electronics, lower power consumption)
How to use
Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port until the latch engages. Verify link status on connected devices and configure interfaces at the operating system or switch level as required by your network setup. Because the cable is passive, no additional power or module negotiation is necessary beyond standard port configuration. Ensure ports are compatible with passive QSFP28 DACs and that firmware or vendor settings do not block third-party direct attach cables if applicable.
Usage recommendations
For reliable operation, use the cable for short-distance connections within the same rack or between adjacent racks, avoid tight bends near the connector ends, and keep the cable away from high-heat sources. Confirm device compatibility with passive QSFP28 DACs and follow equipment vendor guidance for port configuration and maximum supported cable length.
