Rolled Over Network Cable Tested
A common concern is that network cable will be damaged when rolled over by various machines on a job site, but how much of an impact does that actually have?
IPVM tested cables using a cable certifier and cable qualifier to accurately measure performance decay
In this report, IPVM examines:
- Scissor lifts, SUVs, job carts, and wheeled garbage cans rolling over cable
- Impact of cables without a spline, with a 2-way spline, or a 4-way spline
- Certification Results
- Qualifier results
- Recommendations
