On the other hand, I know of several security integrators who subcontract their large network cable installations to companies who specialize in that work. Their subcontractors use cable testing equipment and provide them with a cable test report certifying that the cable installation is sound. Their own technicians also certify the cable work that they perform themselves on smaller projects.
While network test equipment exists in the $4,000 to $12,000 range, a good network cable tester can be had for about $500.
It is worth mentioning that there are also cable testers that show the PoE power draw of installed equipment, which can be used to determine the total draw on a PoE switch. A complete examination of cable testing equipment is beyond the scope of this column, as is a discussion of cabling infrastructure standards and training.
