LABSHEET 6: TRANSMISSION MEDIA

1. Identify the following scenario either fiber optic or copper (UTP). (Fiber/Copper) a. A Company must provide network connectivity between three buildings on a single campus. The cables must be run outside and there is a high probability of lightning storms in the area.  Fiber. b. A company must provide network connectivity between two buildings located 1 km apart.  Fiber. c. A company must provide 100 Mbps connectivity to users located in their main office by running the central switch to the individual desktops. The maximum distance from the switch to a workstation is 60 meters.  Copper. 2. Identify the following scenario is a cabling best practice or not. (Yes / No) a. In an effort to prevent people from tripping over cables, Charles ran the cables through the false ceiling over fluorescent lights.  No. b. Yasmin labeled all cables and recorded their location as she installed them.  Yes. c. Damon decided to follow T568A termination cabling standard for all straight-through cabling needs in his network.  No. d. Samuru needed to connect a device to the network. She located a bunch of old, hand-terminated cables in a drawer. Assuming the cables were good, she selected one and connected her device.  No.
