Well, typically how you stand out as anything is to ensure it's on your resume in your job experiences along with what you accomplished with it. Make sure that you list your jobs that you did cable installation and work with low voltage. Anytime on those jobs you completed a cable installation project ahead of time or without using all the materials, list that as an accomplishment. Emphasize - but don't spam - cable installation and low voltage work on your resume. Rather than assertion, be confident and enthusiastic.

You can buy the BICSI "Information Technology Systems Installation Methods" (ITSMM) manual and read through it. At $260 it's a little pricey, but it's a good read for understanding the proper way to install structured cabling:https://www.bicsi.org/education-certification/[email protected]/technical-publications/information-technology-systems-installation-methodsIt has a lot of good information that might help you understand what's going on. Also, it might cause you to die on the inside as you see just how much structured cabling isn't done to code/standards. I'm not even talking minor stuff, but major stuff like just tossing cable across the ceiling tiles and not using plenum-rated cable when it should be used which are both life and health threatening if a fire breaks out.You can get BICSI certified. They have copper and fiber cabling installation certification courses along with other ones.
