The 100Base-TX (sometimes referred to 100Base-T) cable was until 2010 maybe the most popular cable about since it has actually actually changed the larger 10Base-T and 10Base-2 (Coaxial). The 100Base-TX cable provides fast increases to 100Mbits and also is an ext reliable because it uses CAT5e cable (see the CAT 1/2/3/4/5 page).There is additionally 100Base-T4 and also 100Base-FX available, i beg your pardon we discuss at the end of this article.

So what does 100Base-TX/T4/FX mean?

We space going to rest the "100Base-T" into three components so we can make it easier to understand:


The number 100 represents the frequency in MHz (Mega HertZ) for which this cable is made. In this situation it is 100 MHz. The better the MHz, the greater speeds the cable deserve to handle. If you try to usage this type of cable for higher frequencies (and, therefore, speeds) it will certainly either not work or become extremely unreliable. The 100 MHz rate translates come 100Mbit every second, which in theory means 12 Mbps. In exercise though, friend wouldn"t get an ext than 4 Mbps.


The indigenous "Base" describes Baseband. Baseband is the type of interaction used by Ethernet and also it method that when a computer is transmitting, it provides all the easily accessible bandwith, conversely, Broadband (cable modems) share the bandwidth available. This is the factor cable modem users notification a slowdown in speed when they are associated on a liven node, or once their ar is downloading and install all the time at preferably speed! that course with Ethernet you will notice a slowdown in speed yet it will certainly be smaller sized in comparison come broadband.


The "T" refers to "Twisted Pair" physical medium that tote the signal. This reflects the structure of the cable and tells united state it consists of pairs which space twisted. Because that example, UTP has actually twisted pairs and this is the cable used in such cases. The 100Base-T is used periodically to refer to the 100Base-TX cable specification. For more information, watch the "UTP -Unshielded Twisted Pair" web page where friend can discover information ~ above pinouts for the cables. Every 100MB rated cables, except the 100Base-FX, usage CAT5 cable.


The TX (sometimes referred together "T" only) way it"s a CAT5 UTP straight through cable using two of the four easily accessible pairs and supports increases to 100 Mb. Maximum length is 100 meters and minimum length between nodes is 2.5 meters.


The T4 method it"s a CAT5 UTP straight through cable making use of all four accessible pairs and supports speeds up to 100 Mb. Maximum size is 100 meters and also minimum length between nodes is 2.5 meters.


The FX method it"s a 2 strand fiber cable and also supports speeds up to 100 Mbs. Maximum length is normally up to two kms.

To summarize, store the following in mind:

100Base-TX/T4 functions for 100 Mb networks only and also uses unshielded twisted pair cable v RJ-45 connectors at each endAll CAT5 UTP cables have 4 pairs that cables (eight wires).100Base-TX (sometimes referred to as 100Base-T) provides two the the four easily accessible pairs in ~ the UTP cable, whereas the 100Base-T4 provides all 4 pairs.100Base-FX likewise works for increases to 100 Mb but uses fiber optic cable instead of UTP.
