ACT AddOn Certification Test

Testing is really what sets us apart. Our in-house staff of lab technicians have fine tuned our process for over a decade. With an industry-leading Data Traveler process, every single product is put through our rigorous specifications, tested to OEM standards as well as physically tested in its intended environment. We take your exact configuration and recreate it in our lab to guarantee its functionality and performance. We do this with every product 100% of the time.

Code that makes the difference

Not only are our products put through a rigorous testing method, each part is coded in our in-house lab. With advanced Firmware and DOM coding all Network Transceivers and Direct Attach Cabling are programmed to the OEM specification. We pride ourselves on our internal programming team and their ability to replicate authenticated code.

Custom Coding Solutions

Most companies won't bother with custom networking solutions. We realize that today's data centers can be filled with multiple manufacturers' parts and that at some point they need to communicate to one another. At AddOn, we provide custom coding solutions to fit our customers needs. If needed, we can deploy field technicians to troubleshoot along side IT Directors to come up with a customized solution. We believe in providing the full spectrum of networking solutions to our customers.
