The length constant can vary from cable to cable, even of the same type produced by the same manufacturer. It can also vary

TESTING CONTINUITY - OVERVIEW
When testing for continuity of a cable, you are checking that all conductors within a cable are connected properly from one end
TESTING CONTINUITY - TERMINATED OR INSTALLED RJ45/RJ12 CABLE
Testing Continuity
Testing Continuity-Installed
8-wire Ethernet cables can have an additional set of errors. A miswire simply means that the pin on one side of the cable is not
connected to the identical pin on the other side of the cable (for example, pin 2 on one side is connected to pin 6 on the other side).
Certain pairs of conductors are required to be twisted together from endpoint to endpoint. These errors are called split pairs, and
can be present in cables that don't have any miswires.
Testing continuity is not the same as testing bandwidth. Other testers exist for verifying the amount of data that can pass through

to the RJ45 port (if you are testing an Ethernet cable) or RJ12 port (if you are
testing a phone cable) located at the top of the main tester body. If testing a wall port, connect a known good patch cable

The first and most convenient way to identify installed cables is by using location ID remotes. Using location ID remotes, you can trace
The second way to identify cables is using the VDV Scout
Pro 2's built-in analog tone generator. The tester will place a low-frequency
voltage on the cable. By using an analog tone probe (Klein Tools VDV526-054, VDV500-060, or most other manufacturers’ analog
tone probes, sold separately), a cable can be identified by the tone it is carrying. This technique only allows one cable to be traced per
tone generator, but has additional benefits like the ability to trace a cable manually behind certain wall materials, or trace unterminated
cables of non-standard types.
LanMap™ Location ID Remotes cannot be used to verify continuity

T568A Cable with Split Pairs:
A common error in building a cable is to put all the pairs in pin sequence 1-2, 3-4, 5-6 and 7-8. This will
produce the correct continuity, but the pairs are designated to be on pins 3-6 and 4-5 in the middle of the connector for compatibility with
phone wiring. This wiring error is only detected by the split pair test since the designated pairs are not twisted together.
