Frequently Asked Questions
What is a 100G passive DAC cable used for?
A 100G passive DAC cable connects high-speed network equipment within data centers over short distances. It's commonly used for server-to-switch, switch-to-switch, and storage interconnects where low latency and cost efficiency are priorities.
Why choose a passive QSFP28 DAC over active or optical solutions?
Passive DAC cables eliminate power consumption, reduce heat generation, and offer lower total cost of ownership compared to active DACs or optical transceivers. They're ideal for distances up to 5-7 meters where signal integrity remains excellent.
Is this 50CM DAC cable compatible with my network equipment?
Yes, this MSA-compliant QSFP28 copper DAC works with any standard 100G Ethernet equipment featuring QSFP28 ports. Verify your device supports 100G DAC connectivity before purchase.
What makes the 50CM length ideal for data centers?
The 50CM length is optimized for top-of-rack and intra-rack connections, providing flexibility without excess cable while maintaining signal integrity. This length reduces clutter and simplifies cable management in dense server environments.
