In this guide, we'll break down everything you need to know: how these two cable types differ in construction and protection level, where each performs best, how they stack up on upfront cost versus long-term value, and what to consider before you specify either one for your next. In this guide, we'll break down everything you need to know: how these two cable types differ in construction and protection level, where each performs best, how they stack up on upfront cost versus long-term value, and what to consider before you specify either one for your next. Executive Summary: Both armored and unarmored fiber optic cables transmit light signals at near-speed-of-light speeds. But when it comes to protecting your fiber optic network from rodents, construction damage, and harsh weather, the difference between these two cable types can mean the difference. Every optical fiber cable project faces the same critical question: should you choose an armored cable or a non-armored one? At first glance, the choice may look simple. Armored cables appear stronger, non-armored cables are cheaper. The wrong choice can: Or. When choosing fiber patch cables, one common question arises: Should you choose armored or unarmored fiber optic cables? Each option is engineered for different environments and protection requirements, offering distinct advantages in durability, flexibility, and cost. Understanding their. This Cable Jacket Selection Note is intended to provide the reader with an organized selection methodology when selecting the optimum optical cable for a specific application. You select between them based on route exposure, rodent risks, burial requirements, tension loads, and overall ODN architecture.
