Category 5 cable is usually called in breif as Cat5 cable. This includes UTP cat5 cable, cat5e cable, SCTP cat5 cable, RJ45 jack cat5e, Patch panel cat5e and cat5e Patch cable.
Let's talk about UTP cat5 cable first. The UTP is short for unshielded twisted pairs. It is made up of 4 pairs (8 conductors) of twisted conductors.UTP cat5 cable is most often used for transfering data. At At present, cat5 cabe is the most common cable in the world. Frequency range of UTP cat5 cable is 1MHz to 100MHz, and attenuation is 24dB.
Cat5e cable is short for Category 5e cable. This is upgrated UTP cat5 cable. They have similar structure, the difference is that cat5e cable is made to more strigent standards than cat5 cable. This is aimed to transmit at a speed of 1 gigabit per second maximum. The frequency range for cat5e cable is 1MHz to 100MHz. Attenuation is 24dB.
SCTP cat5 cable is another kind of cat5 cable. SCTP is short for Screened Twisted Pairs. This cable is similar to cat5e cable except that it has a shield to protect the conductors from interfrence. This cable is widely used in European countries. The specifications are almost the same as cat5e cable.
Cat5e RJ45 jack is a work outlet. This is designed to maintain cat5e cable peformance.
