## Summary description

Twinax direct attach copper (DAC) cable CBO QSFP-100G-CU1M-HU is a 1-meter QSFP28 male-to-male assembly supporting 100 Gbit/s links. Designed for short-reach interconnects between compatible 100G ports, it provides low-latency, power-efficient connectivity for switches, routers and NICs in data centers and server racks.

## Long description

The CBO QSFP28 100G DAC cable QSFP-100G-CU1M-HU 1 m Male-to-Male is a 1‑metre twinax direct attach copper assembly engineered for short‑reach 100 Gbit/s links. This QSFP28 passive cable connects compatible QSFP28 ports on switches, routers and network adapters to deliver a low‑latency, power‑efficient physical interconnect for data‑centre top‑of‑rack and server‑to‑switch connections.
Advantages
The cable provides reliable 100 Gbit/s connectivity with minimal signal loss and inherent low latency due to its copper twinax construction. Its 1 m length reduces clutter in dense rack environments and simplifies cable management while avoiding the need for separate transceivers. The QSFP28 male‑to‑male form factor is compatible with industry standard QSFP28 ports and is suitable for high‑density installations where power and cost efficiency are priorities.
Suitable for
 Short‑reach interconnects between switches and routers within racks
 Direct connections from servers or NICs to aggregation switches
 High‑density data centre top‑of‑rack deployments
 Low‑latency networking for HPC and storage clusters
Key specifications
 Connector type: QSFP28 male to QSFP28 male
 Data rate: 100 Gbit/s
 Length: 1 metre
 Cable type: Twinax direct attach copper (DAC)
 Typical application: Short‑reach point‑to‑point links
 Latency: Passive copper, inherently low
How to use
Insert each QSFP28 connector firmly into the corresponding QSFP28 port until the retention latch engages. Ensure both ends are connected to compatible 100G ports on devices that support passive twinax DAC cables. Route the cable to avoid sharp bends and mechanical stress; maintain the specified minimum bend radius to preserve signal integrity. No external power or configuration is required beyond ensuring the host devices are configured for the intended 100G link.
Usage recommendations
Verify compatibility with the target switch, router or NIC vendor and confirm link settings before deployment. Use the 1 m length for short‑reach connections inside racks or between adjacent units to minimize attenuation and maintain optimal thermal and cable management conditions.
