A “Network CT100 Cable Tester” appears to be a specific model or type of cable tester used for checking the quality and connectivity of network or Ethernet cables. These testers are essential tools for network technicians and IT professionals who work with network cabling infrastructure. Here are some common features and functions you can expect from a network cable tester like the Network CT100:

1. Cable Testing: It can verify the continuity and proper wiring of Ethernet cables, including Cat5e, Cat6, and Cat6a cables. It checks for open circuits, short circuits, and miswiring.
2. Wire Mapping: The tester typically displays a wire map of the cable to ensure that each conductor is correctly connected at both ends.
3. Length Measurement: Some cable testers can measure the length of the cable and help identify the location of cable breaks or faults.
4. Testing Remote Units: Many cable testers come with remote units that can be attached to one end of the cable, allowing you to test cables over longer distances.
5. Display: The tester typically has an LCD screen or LED indicators that show the test results, making it easy to identify cable issues.
6. Tone Generator: Some cable testers have a tone generator function, which can help identify a specific cable within a bundle or identify cable endpoints in a wall.
7. PoE (Power over Ethernet) Testing: Advanced models may support PoE testing, ensuring that both data and power are delivered correctly to devices such as IP cameras or VoIP phones.
8. Shielded Cable Testing: It can check the continuity and quality of shielded Ethernet cables (STP).
9. Fault Localization: The tester can pinpoint the location of cable faults or breaks, which is especially useful for troubleshooting.
10. Battery or Power Source: Cable testers usually run on batteries or have a rechargeable internal battery, ensuring they can be used in various field conditions.

The “Network CT100″ may be a specific model or brand of cable tester, and the features and operation might vary depending on the manufacturer and model.
