RE: Physical Layer and Data Link Layer Christopher Twiner 9/5/2016 6:12:00 If we were planning for gigabit networks then the maximum for twisted pair networks is 100meters or around 330 feet. After this the signal needs to be "amplified need to be plugged into a switch to perform the amplification and allow for a further 100m if needed. RE: Physical Layer and Data Link Layer Labib Makar 9/7/2016 8:26:36 Hi Christopher, Thanks for your great posting. as you mentioned above, the maximum length for twisted pair networks is 100 meters. But to be honest, this is in theory, practical real world you would find distances that longer than 100 meters and those kinds of cables still function probably. or even you might see distance than 100 meter and the cable is not that efficient. there are many factors affect the performance of the cable, some of these factors are for example, the

RE: Physical Layer and Data Link Layer Winifred Oloni 9/5/2016 9:05:39 Yes I would consider the maximum cable length limitations . According to our text "When end users operate equipment at maximum distances, it is important to re that they must meet the restrictions on all types of equipment used, including the electrical environment, cable construction, and cable wiring. This means that wh want to operate at a maximum cable distance, you must contact the computer and/or modem vendors to obtain their maximum cable distance before you proceed FitzGerald, J., Dennis, A., Durcikova, A. (2015). Business Data Communications and Networking, 12th Edition . [VitalSource Bookshelf Online]. Retrieved from RE: Physical Layer and Data Link Layer Omar Fares 9/5/2016 9:56:49 I would suggest to use shielded cables and move them away from the source of noise to prevent error. I would also suggest repeaters to a attenuation. I would suggest repeaters rather than amplifiers because amplifier amplifies the signal and the noise. On the other hand, repe regenerates the original signal. RE: Physical Layer and Data Link Layer Joseph Office 9/6/2016 10:51:2 For the accounting firm to reduce network traffic and interference, there are a number methods that can add to this effort. In terms of cabling, it is recommended company use cable that is properly shielded to reduce interference from outside signals. In addition, using a heavy duty cable shielding will also be beneficial as it is
