Alt vide you with a list of pass/fail results, it is important to know not only what is b also what results the tester is programmed to evaluate as passes but and failures. Master I 1. What is the difference between the permanent link and channel testing . If you have installed a Category 6A cable, what isthe maximumNEXT that canbe sup ported for a 500MHz channel? What is the insertion loss budget for a 300 meter link intended to operate at using OM3 fiber? 3. 10GBase-SR Identify cable testing tools. Cable-testing tools can range from simple, inexpensitea litany mechanical devices to elaborate electronic testers that automatically supply you vw of test results in an easy-to-read pass/fail format. It's important to identify these and u stand their benefits. Master It You are asked to install a fiber-optic lin and splice points. Based on the cable length, number of connections, and splice points you have estimated the insertion loss to be verv close to the insertion loss budget for the intended application. After installing the link, you find that the insertion loss is higher than the budget. It's now time to go and find the points in the link that could be causing unusually high loss. You suspect that it may be due to the splices in the system. Which measurement tool would you use and why? k that requires multiple connections Troubleshoot cabling problems. Cabling problems account for a substantial number of network support calls. Because network uptime is a critical condition for maximizing an organization's business, troubleshooting problems quickly is very important. Understanding some basic steps will help you improve the speed of your process and repair of a network customer's Master It What are the basic recommended steps for troubleshooting a cable
