Engineers and technicians in the telecommunications field constantly assess and reassess network stability and connection strength. As we adapt to what will soon be a 5G world, network cable testing will be key to maintaining informational infrastructures, giving companies a financial and technological edge over competitors and helping them to fulfill CISPR, EN and IEC standards. Network testing can be divided into three general branches: data network, cellular network and radio network tests. LAN cable certification, discussed below, is one of the most important communications tests included in these categories.
LAN Cable TestING
LAN cable testers, also known as cable certifiers, test local area networks (LAN) composed of fiber, copper, and twisted pair cables for strength and connectivity and to identify and troubleshoot issues. LAN cable testing continues to be one of the most essential steps in comprehensive network testing; cable certification is a manufacturer’s final step in granting warranties for new cabling installation, and is considered “future-proof” as new technologies in the field are designed specifically to meet certification standards.
Communications Test Equipment
Data network testing measures the efficacy of fiber, copper and twisted pair wired connections. During cable installation, certification, verification and troubleshooting, cables need to be checked for connectivity and faults to avoid outages by data network diagnostic tools.
To analyze radio signals, a radio tester is utilized to determine whether a signal is produced in the right bandwidth and assess parameters like single sideband (SSB) phase noise, modulation/demodulation and harmonics.
Cellular network test instruments monitor the RF components that send information between cell towers and wireless devices. Smartphones, Wi-Fi signal quality and video data transfers all depend on cellular testing, especially the monitoring of antenna for high levels of RF or conducting alignment tests.
