When selecting the appropriate Category of cable to support your network, note that there are different grades within each Category. A higher grade cable with the proper installation will allow for a higher margin of error, ensuring top performance today and an extra buffer to support future technology. Properly selecting Cat5e, Cat6, Cat6a, Cat7 solutions will optimally support current and future network speed requirements. But which one should you choose? This text will give you some guidance.

The Cat5e has Replaced the Cat5 Ethernet Cable

cat5e ethernet cableCat5 cable can support 10/100 Ethernet. That is, Ethernet and Fast Ethernet. However, Cat 5e cable can support Ethernet, Fast Ethernet, and Gigabit Ethernet. Cat5e Cable is completely backwards compatible, and can be used in any application in which you would normally use Cat 5 cable. Crosstalk is the electrical interference that results when one wire’s signal affects another wire’s signal. Cat5e cable has been improved over Cat5 cable in this respect, and cross talk has been greatly reduced. We all know that bandwidth is directly related to network support. The greater the bandwidth, the greater the information-carrying capacity in a given period of time. Cat5e cable is rated at 100 MHz, and it is this increased bandwidth (compared to Cat5 cable) that allows it to support Gigabit Ethernet. Since 1G is widely used today, the Cat5e has gradually replaced the Cat5.

Use Cat5e or Cat 6 Ethernet Cable?

cat6 UTP patch cableCat6 is a standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the Cat5/5e and Cat3 cable standards. Compared with Cat5 and Cat5e,  Cat6 features more stringent specifications for crosstalk and system noise. The cable standard provides performance of up to 250 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T/1000BASE-TX (Gigabit Ethernet). We may notice that both Cat5e and Cat6 can support Gigabit Ethernet, however, Cat6 is certified for Gigabit networking and will perform better over longer distances. So choosing the Cat6 cable will be more stable to meet the Gigabit needs. But one thing you should keep in mind is that your network is only as fast as your slowest component, so unless every piece of your network (routers, cables, etc.) supports Gigabit Ethernet, you will not be able to reach those speeds.

Differences between Cat6 and Cat6a Ethernet Cable

cat6a stp cableThe latest standard from the TIA for enhanced performance standards for twisted pair cable systems was defined in February 2009 in ANSI/TIA-568-C.1. According to this standard, Cat6a is also called Augmented Cat6, which is 10-Gigabit Ethernet over copper proposal to the Cat6 standard. Category 6a performs at improved specifications, in particular in the area of alien crosstalk as compared to Cat6, which exhibited high alien noise in high frequencies. Cat6 specifies cable operating at minimum frequency of 500 MHz—twice that of Cat 6, for both shielded and unshielded. It can support future 10 Gb/s applications up to the maximum distance of 100 meters on a 4-connector channel. Compared with the Cat6, Cat6a is more effective and flexible. As 10G is more and more widely used, Cat6a will become more and more popular.

Cat7 Will be the Ethernet Cable of Choice

cat7 network patch cableCat7 cables are designed to support much higher frequency signals than Cat5e and Cat6. This allows Cat7 cabling to carry a larger amount of information. Cat7 cable is also able to better protect the signals traveling over the cable. The shielding as well as the tighter twists of the pairs in Cat7 cable lessens the effects of crosstalk and EMI. Cat7 cable is commonly terminated using a GG45 connector, which is a connector that it backwards compatible with the 8p8c RJ45 connectors used on Cat6 or Cat5e cable. The GG45 connector has four additional conductors that provide support for frequencies of up to 600MHz. The higher frequencies allow Cat 7 cable to support 10-Gigabit Ethernet. Currently, Cat7 is not widely adopted. Cat5e and Cat6 solutions sufficiently support the bandwidth requirements of today’s data centers, networks, and end users. Using Cat7 for a connection to a desktop would be unnecessary because the bandwidth would not be utilized. It may also be an unnecessary expense for many data center applications for the same reason. However, as technology advances and requirements increase, Cat7 cable will become more relevant in the data center and desktop connections.

Cat5E Patch Cables,Patch Panels And More In PriceCable

Cat5E Patch Cables are the enhanced version of Category 5 Patch Cables, and go along the same lines as basic Cat5 network cables. The difference between the two is that Cat 5e network cables fulfill higher standards of data transmission. While Cat 5 network cables are common in existing cabling systems, Category 5e network cables have almost entirely replaced Cat 5 in new installations.In PriceCable, provide Cat5E Patch Cables used for network cabling, includes shielded, crossover, flat and solid patch cables ect.

Cat 5e network cables is still widely used in infrastructure, construction, industrial fields, correlates are stable support network transmission, effectively providing gigabit Ethernet, the smooth operation of various applications of web based data communication cable (also called “string”). In 100 MHZ bandwidth, the super five kinds of different brand different line bandwidth, higher bandwidth, channel letter is better.

Cat 5e network cabling is used as a cabling infrastructure for 10BASE-T (Ethernet), full duplex 100BASE-TX (Fast Ethernet) and 1000BASE-T (Gigabit Ethernet, or GbE) networks. The Cat 5e standard provides performance of up to 100 MHz and can be used up to a maximum length of 100 meters.

As with Category 5 (Cat-5) cables, Cat 5e cables typically consist of four unshielded twisted pairs (UTP) of copper wire terminated by RJ45 connectors. Cat 5e is distinguished from the original Cat 5 standard primarily in its performance requirements. Cat 5e has stricter specifications in a number of areas, including Near-End Crosstalk (NEXT), Power Sum Equal-Level Far-End Crosstalk (PS-ELFEXT), attenuation and return loss.A newer specification for CAT5 cable – CAT5 enhanced (“CAT5e” or “CAT 5e”) – supports networking at Gigabit Ethernet speeds (up to 1000 Mbps) over short distances by utilizing all four wire pairs, and it is backward-compatible with ordinary CAT5.

If you want to produce their own cat5e cable, we also provide bulk cat5e cable, it is primarily available in 3 different types, each type has a specific application. Bulk solid Category 5 cable, the most commonly used, is comprised of a Riser Rated (CMR) PVC jacket and solid core conductors. Solid core conductors allow the cable to be run long distances while maintaining performance, but reduces the number of times it can be flexed before breaking. This makes solid cat 5 cable perfect for permanent installation applications (long runs from patch panels to wall plates) where the cable will not move much once installed. Stranded is comprised of a PVC jacket and stranded core conductors making it very flexible. This flexibility allows it to be flexed many times with no negative effects on performance making it perfect for building patch cables. Plenum (CMP) also has solid core conductors, but is built with a low smoke, fire retardant jacket that make it safe for use in plenum air spaces (check your local building codes for requirements).

I suspect that you may need to buy the cat5e patch panels to support the cat 5e patch cord.The patch panel provides the user with the option to reconfigure where the lines are routed to quickly.I’m not sure if you needed,but I want to tell you that,in PriceCable.com,I can find A series of Cat 5E cables related products.Buy with confidence.
