Question
Topic A: Fiber Optic Cabling
What advantages do fiber optic cables offer over twisted pair or other media choices? What are the disadvantages to implementing fiber optic cables?
The impact of EMI on fiber optic cables
Topic B: Twisted Pair Cabling
What is the difference between the T568A and T568B standards? When should you use both standards?
What type of cable would you use to connect two hosts together in a back-to-back configuration using twisted pair cable?
When should you use stranded core twisted pair cable instead of solid core twisted pair?
Which part of the cable is used to carry data?
The impact of EMI on twisted pair cables.
Explanation / Answer
Topic A
1. Extremely high bandwidth
2. Easy to accomodate increasing bandwidth
3. Resistance to electromagnetic interference
4. Early detection of cable damage and secure transmissions
Disadvantages of Fiber Optics:
1. Installation costs, while dropping, are still high
2. Special test equipment is often required
3. Susceptibility to physical damage
4. Wildlife damage to fiber optic cables
Topic B
1. Difference between the T568A and T568B standards - The important difference is the pin positions of Green and Orancge in them. Thses 2 pins are interchanged.
2. We should use cross cable to connect back-to-back configuration.
3. T568B twisted pair cable should be used.
4. Copper wire in twisted pair is used to carry data.
