Week 8 chapter 15

1) What is the difference between the permanent link and channel testing?

The permanent link includes only that portion of the cabling installation that is "permanent" (think punched down). It includes jack to rack -or- wall outlet to patch panel. One connector is allowed at each end but any patch cables must be accounted for and removed from the test results. This generally means you must use the cables that came with your test equipment so the equipment knows exactly what to subtract the channel link includes two or more patch cables and may include multiple patch panels - possibly in multiple closets.

2) if you have installed a category 6a cable, what is the maximum NEXT that can be supported for a 500mhz channel.

26.1

3) what is the insertion loss budget for 300 meter link intended to operate at 10Gbase-SR using OM3 fiber.

ILB = (2 x 0.75db) + (0.3km x 3.5dB/km) = 2.6dB

4) What are the basic recommended steps for troubleshooting a cable problem?

1. Split the system into logical elements.2.Locate the element that is most likely the cause of the problem. 3. Test the element or install a substitute to verify it as the cause of the problem.4.If the suspected element is not the cause, move on to the next likely element.5. After locating the cause of the problem, repair it or replace it.
