Cable Specifications, Limitations, and Considerations
________________, might cause connectivity failure or intermittent connectivity issues. You need to ensure that the Ethernet cable length is not exceeded. If it exceeds the maximum length, you need to install a repeater to amplify the signal. For example, the maximum length of a UTP cable is 100 meters. If you are exceeding this length, then you know there are going to be connectivity issues.
Distance, Even though the distance is something that a Network Administrator doesn't look at when troubleshooting connectivity issues
In an office, above the ceiling tiles, there is a space before the roof. This space is called the ______________, which is used for laying down the network and power cables. In this space, you should use the plenum-rated cables because they use a cable jacket made of low-toxicity material. If a fire breaks out, plenum cables are much safer and do not create toxicated smoke compared to PVC cables. Plenum-rated cables are used in offices, other commercial and residential complexes. ___________, are used in cable risers and elevator shafts where you cannot use plenum cables. Riser-rated cables have the self-extinguish capability to stop a fire from spreading through the cable, which means that the fire cannot spread vertically. It is possible to use plenum cables as a replacement for riser cables but not vice-versa.
Plenum and Riser-rated
1) _____________, other than the outer plastic sheath, each pair is separately insulated in foil or a similar substance, which prevents electromagnetic interferences from affecting the signal transmission taking place within the wire. Even though it is designed to prevent electromagnetic interferences, it is difficult to install and is also expensive. The metallic shielding at both ends must be grounded. STP is rarely used in Ethernet networks. 2)_____________, same as STP, except the four pairs do not have individual shielding. Just like STP, there is an outer plastic sheath. An example of a UTP is the telephone cable.
Shielded and Unshielded, There are several different types of UTP cables available. However, their differentiation is mainly on their transfer rates. CAT1 - Up to 1 Mbps CAT2 - Up to 4 Mbps CAT3 - Up to 10 Mbps CAT4 - Up to 16 Mbps CAT5 - Up to 100 Mbps CAT5e - Up to 10 Gbps CAT6 - Up to 10 Gbps CAT6a - Up to 10 Gbps CAT7 - Up to 10 Gbps Starting from CAT3 to CAT7, all of these cables can run up to 100 meters.
_____________, one of the key reasons for connectivity issues. If everything on the network is working fine except the new system you connected to, you may want to check its speed settings. You should have speed settings, such as 10/100/1000 Mbps, selected according to the network speed. For example, if you have a switch that operates at 100 Mbps but your system's network adapter is configured at 1000 Mbps, you will likely face issues.
Speed The speed will be limited with the network adapter settings. It is also limited by the type of cable you use. For example, even if the network adapter is configured with 1000 Mbps, but the cable you use is CAT5, you will be able to transmit the data at a speed of only up to 100 Mbps. To ensure that speed does not become a limitation, you need to use the correct speed and cable.
_____________, data rate, which defines the amount of data transmitted in a specific time. A system may not be able to meet the throughput threshold due to several factors. For example, if you are trying to transmit the data from your system to a file server and find that transmission is slow, you need to monitor the network adapter to ensure a reasonable amount of .............
Throughput, The throughput can also be limited by the type of cable you use. If a cable is capable of 100 Mbps speed, no matter at what speed or how much data you send over this cable, it cannot go beyond the 100 Mbps speed. To test the network adapter for the throughput, you need to use throughput testers, which help you test the upload and download speeds. However, other system bottlenecks, such as constant read and writes on the hard drive, may impact the transmission from the system. This is because the hard drive is either receiving or sending data using the network adapter.
