|To test just a spool of cable, the following is by far the quickest method. Dont forget to test from both ends; the lengths should be the same. If not, then there is a break in the cable reel. |
This test should be done on all spools of cable prior to installation. In the absence of an OTDR, use an optical loss tester. Do not use a visual Fault Locator. Even if the cable has a break in it, you may see light at the end of the cable.
