Cat5e cable is one of the most common types of cabling used in the networking industry. It is the successor of the Cat5 cable and is backward compatible with Cat5. The "e" in "Cat5e" is the Roman numeral V and stands for "enhanced." The distinguishing feature of the Cat5e cable is its performance and features. It has a performance parameter of 250 MHz and contains four twisted wire pairs with equal length.
Cat5e Ethernet Cable -- be it Cat5e Riser Cable, Cat5e Plenum Bare Copper, or Cat5e PVC Cable -- is one of the most widely used ethernet cables. If you are mulling over buying Cat5e ethernet cable, read this updated guide to make an informed decision.
Cat5e Cable - Understanding The Title
The “Cat” in the Cat5e stands for the category, “e” stands for enhanced, and 5 represents its generation. In nutshell, Cat5e is an enhanced 5th generation cable. This cable supersedes Cat5 ethernet cable.
Cat5e cable is an unshielded twisted pair cable that is used for Ethernet connection in computer networking installations. The Cat5e cables are available in various categories depending upon the transmission capacity. The Cat5e cables are less expensive than the Cat6 cables but are not backward compatible with the Cat5 cables. The Cat5e cables are used for up to 10BASE-T applications.
Cat5e Cable - Inner Structure
The inner structure comprises 8 conductors that are tightly bundled together in 4 twisted pairs. These twisted pairs reduce the effects of crosstalk and also cancel electromagnetic interference.
The conductors are the most important part of any ethernet cable as they transfer signals from one device to another and also connect devices to the internet network. They come in 2 different materials:
Pure Copper is also known as bare copper and solid copper
Copper-Clad Aluminum
If there are no budget constraints, then you should go with the cables with pure copper conductors. Why? Let us explain. Pure copper conductors have way less attenuation than copper-clad aluminum conductors. Attenuation is a loss of signal strength. As the attenuation is higher in CCA cables, the connectivity continuously disrupts in harsh environments (places where crosstalk and EMI are high).
Also, pure copper conductors have far less DC resistance; in fact, as much as 55% less DC resistance. It means bare copper conductors transfer more energy into signals whereas CCA conductors far less into signals (and more into heat).
Last but not least, pure copper conductors provide top-notch protection against EMI and crosstalk. The only factor where CCA conductors are better than their pure copper conductors is that of pricing. But what’s the point of saving a few bucks when the whole connectivity will be disrupted?
Cat5e Cable - Data Transfer Rates & Bandwidth
Be it Cat5e Plenum Bare Copper, Cat5e PVC Cable, or Cat5e Riser Cable, the data transfer rates and bandwidth capacities remain the same for enhanced 5th generation cables.
The Cat5e demonstrates maximum data transfer rates of 1 Gbps up to a distance of 50 meters or 164 feet. The data transfer rate plummets to 100 Mbps when length increases to 100 meters or 328 feet. The cable comes with a bandwidth capacity of up to 350 MHz.
Types of Cat5e Ethernet Cable A Cat5e ethernet cable comes in the following 3 types:
Cat5e Plenum Bare Copper
Cat5e Riser Cable
Cat5e PVC Cable
Let’s discuss each one of them in detail.
Cat5e Plenum Cable
You can identify a Cat5e Plenum Bare Copper cable from CMP-rated marking on its outer jacket. The CMP is the highest rating for jackets of the ethernet cables. As these cables are fire retardant and UV resistant, you will run them in the plenum or horizontal spaces of the buildings.
Cat5e Riser Cable
A Cat5e Riser Cable comes with a CMR rated jacket. This is the second best rating for jackets of the ethernet cable. These cables are also fire resistant and UV resistant. You will buy a CMR-rated or riser-rated ethernet cable if you want to run one in the vertical or riser spaces of the buildings. Though riser-rated cables are also made from supreme quality polyvinyl chloride but the same is not as fine as that of plenum-rated cables.
Cat5e PVC Cable
Buying network cables isn't the most interesting task in the world, right? But it has to be done. When you are buying Cat5e cables, it's important to know the difference between the PVC cables and the Plenum cables. This blog will look at what the differences are so you can make an educated choice.
A Cat5e PVC Cable is made from low-quality polyvinyl chloride. You will buy a PVC cable if you need to run one in the outdoor spaces. This cable too has some salient features such as the jacket is chemical resistant and sunlight resistant.
Cat5e Cable - STP vs UTP
Two factors that heavily influence the performance of Cat5e cable in a negative manner are none other than EMI and crosstalk. To provide protection against the same, manufacturers add an extra layer or layers of protection in the form of a foil sheet.
This sheet is either wrapped around all 4 twisted pairs combined or over each twisted pair separately. Such cables that have extra protection against crosstalk and EMI are called STP (shielded twisted pairs) cables. You will buy an STP cable if you need to run it in harsh environments - spaces where EMI and crosstalk are excessive.
Unshielded Twisted Pair (UTP) cables, as the name suggests, do not have any extra layer of protection. STP cables are much more expensive than their UTP counterparts. You will buy a UTP Cat5e Plenum Bare Copper or Cat5e Riser Cable if you need to run it in spaces where crosstalk and EMI are non-existent.
Cat5e Applications
A Cat5e cable supports the following applications: ANSI X3T9.5 TP-PMD (FDDI), ATM PMD 155 Mbps IEEE 802.3 Fast Ethernet :10 Base-T, 100 Base-T4, 100 Base-X IEEE 802.5 :4/16 Mbps Token Ring, IEEE 802.12 :100 Base-VG.
Conclusion:
Cat5e cable is the latest Ethernet cable standard, which is used for 10/100/1000-Base-T Ethernet applications. The cable is installed in most offices, businesses, and homes. The cable supports Ethernet, Fast Ethernet, and Gigabit Ethernet networks. Cat5e cable serves as an alternative to Cat3 cable, which is not intended for high-speed Ethernet applications.
Cat5e cable is an unshielded twisted pair (UTP) cable. It has eight wires, which are colored with different colors. The eight wires are twisted together to minimize interference. Another type of cable, Cat5e cable with an extra protection layer, is Cat5e cable with an extra protection layer. It is used to protect the cable from cable-destroying pests.
