Immune to Lightning and Other Micro Interruptions
Twisted pairs are susceptible to impulse noise and voltage spikes from things like lightning, electric motors, radio transmitters, etc. These noises are typically large and short in duration. If the noise source is large enough, the noise will be seen as micro-interruption on the transmission lines. For some systems, micro-interruptions result in a re-synchronization or full-retrain of the link; a retrain is service affecting and may have service down for several seconds or in some cases minutes depending on the particular technology. Aktino systems can “ride through” micro-interruptions and resume data transmission without interrupting service. The ability to ride through micro-interruptions are part of an array of features that provide unprecedented reliability and resiliency to copper plant.
Enhanced Noise Immunity Can Eliminate Unavailable Seconds (UAS)
Riding through micro-interruptions is especially important for applications like mobile backhaul where systems are exposed to lightning. Although there is a lot of variation, lightning transients typically have durations of tens to hundreds of microseconds. Aktino systems can ride through these interruptions and maintain service even in the presence of lightning.
Evidence of the significant benefits of this functionality was demonstrated in a mobile backhaul trial with a major service provider conducted under the challenges of harsh weather conditions. In the trial, Aktino’s Ethernet over Copper solution performed to meet and exceed Fiber Service Level Agreements (SLAs). In evaluating the Aktino solution's performance during lightning storms, the provider reported that it addressed a key weakness of legacy T1 technology by demonstrating a significant decrease in unavailable seconds (UAS). As a result, providers now have fast and cost-effective solution that not only meets their bandwidth and reach requirements, but also their reliability requirements.
