Why Resilient Tec?
Enterprise AI Infrastructure, Backed by People Who Know It
Resilient Tec was built for one reason: serious AI and networking teams need a supplier that delivers the right hardware, fast — and stands behind it unconditionally.
We're not a marketplace. We're not a liquidation warehouse. We stock, test, and support every product we sell — from 25G SFP28 DAC cables to 800G OSFP breakout assemblies — and we back it all with a lifetime, no-questions-asked warranty.
✓ Lifetime Warranty on Everything
Every product we sell — new or refurbished — is covered. If it fails, we replace it. No expiration date, no registration required, no hoops to jump through. We call it radical transparency: if the gear isn't working, we make it right.

✓ Same-Day Shipping
Orders placed before cutoff ship the same business day. When your rack is down or a build is stalled waiting on a cable, days matter. We maintain deep inventory across NVIDIA/Mellanox, Cisco, Arista, and Brocade-compatible optics and DACs so we can ship what you need, when you need it.
✓ Fully Tested — New and Refurbished
Every refurbished unit is tested before it ships. We don't drop-ship mystery inventory. Transceivers, DAC cables, and server components are inspected and verified to spec. When you receive it, it works.
✓ Deep Expertise in High-Speed Interconnects
We specialize in the hardware that moves data between GPUs, switches, and storage: DAC cables, AOC cables, optical transceivers, and breakout assemblies from 1G through 800G. Our team understands the difference between HDR and NDR, when to use a passive DAC vs. an active optical cable, and which SKUs are actually compatible with your switch — not just what the spec sheet says.
✓ Compatible With Your Gear
We carry OEM-compatible optics and cables that are protocol-tested and functionally identical to branded equivalents — at a fraction of the cost. Our inventory covers NVIDIA/Mellanox, Cisco, Arista, and Brocade platforms. If you're running InfiniBand HDR, 400G Ethernet, or building a DGX cluster, we have the exact cable you need.
✓ Competitive, Transparent Pricing
Enterprise hardware doesn't have to come with enterprise markups. We price fairly, post prices publicly, and offer volume discounts for larger builds. No hidden fees, no bait-and-switch availability.
✓ Real Support
Have a compatibility question before you buy? Not sure if you need an AOC or a DAC for a 7m run? Call us at 888.442-3849 or use our contact page. You'll reach someone who actually knows the product — not a script reader.
