The company wants to upgrade its network infrastructure to include
1000Mb switches and 10/100/1000 auto sensing network interface cards in
each desktop. Recommend the cabling type that you would use in this
You need to use a cable that can pass 1000 Mb/s. I would recommend using either of the following optical fiber (1000BASE-X), twisted pair cable (1000BASE-T), or shielded balanced copper cable (1000BASE-CX).
P.S for the previous question you asked about connecting a machine 400 meters away please note the following:
"Ethernet is subject to the "5-4-3" rule of repeater placement: the network can only have five segments connected; it can only use four repeaters; and of the five segments, only three can have users attached to them; the other two must be inter-repeater links." reference http://www.difi.net/top_menu/44/mid_menu/58/89/left_menu/127
