37. What type of fiber cable should be placed in the ground for a campus network? - I would suggest using a combination of both Single mode and multi-mode. Single mode would offer a higher transmission rate and at a greater distance. I would use these runs to interconnect the greater distantance buildings. For the shorter runs, I would use multi-mode which is less expensive and can provide equivalent speeds at shorter distances. Having a combination will be more cost effective and keep transmission speeds high in the gigabit range.
38. What type of networking cables would you use in a new building? Discuss the issues related to your selection. - First we need to look at all cables and see what will be the most cost effective choice. If using standard copper (Cat6e) you will get gigabit transfer speeds but at only a 328 foot maximum run without repeaters. This cable choice is ideal at the office level with a central switch. If you have to go vertical in between floors and underground, then fiber optic would be ideal. These can go miles per single run and can transfer 100’s of gigbits per second. There is no EMI and is very secure. You could also use multi-run fiber for desktop computers if you require very secure connections that are not susceptible to EMI and can’t be tampered. Most networks today use a combination of both fiber and copper to suit their needs.
