Twisted copper cables (TCCs) is a crucial part of the
framework for Internet of Things (IOT). In Ethernet cabling communication
systems, return loss is a major signal limiting factor that needs to be
evaluated before deployment. The prevalence of sub-standard and copper clad
aluminum (CCA) cables in the market makes a method of evaluating cables
necessary to minimize signal degradation after installation. Installation
stresses are also anticipated from repeated coiling and uncoiling of cables.
There is the need for an objective method of evaluating TCCs selected for
deployment. In this paper, four category 6 unshielded TCCs from different
manufacturers including one CCA cable were selected for the test. In this
paper, the four cables were subjected to repeated coiling tests anticipated
during installation to obtain their return loss. The Feature Selective
Validation (FSV) tool which is a standardized tool for objectively comparing
data sets was used to evaluate their resilience or otherwise to the effects of the
coiling. The results show that the CCA cable gave the highest variations in
return loss from the coiling tests in all the four pairs. This indicates that
the CCA cable presented the least resilience to the cables manipulation and has
the highest potential to degrade after installation. The method provided can be
used by cable installers and engineers to undertake an objective evaluation of
TCCs performance measurements before deployment. This can help them minimize
potential liabilities that may arise from installing substandard cables such as
fire outbreak and poor quality of service.
