Can I Use Cat5e Patch Cable With Cat6 Patch Panel?

As a key component of copper cabling system, copper patch panel is popular with people. And there are Cat5e patch panels and Cat6 patch panels available on the market. It is not difficult to understand that Cat5e patch panel is used with Cat5e patch cable, while Cat6 patch panel is used with Cat6 patch cable jointly. But can I use Cat5e patch cable with Cat6 patch panel or Cat6 patch cable with Cat5e patch panel? This article will tell you the answer.

Overview of Cat5e and Cat6 Patch panel

First, let’s have a brief overview of Cat5e patch panel and Cat6 patch panel. Cat5e patch panel is compliant with TIA/EIA 568 industry specifications and is used for high speed LAN transmission. In addition, Cat5e patch panels are available in 6-port and 8-port module groupings, in 8, 12, 24, and 48-port sizes. The high density panel design can be mounted to standard racks or cabinets, accommodate top, bottom or side cable entry, and also save rack space. While Cat6 patch panel is specially designed for 1G Ethernet applications. It also meets the TIA/EIA 568 industry specification and each patch panel terminates with standard 110 termination tools on the rear, which allows quick installations. Cat6 patch panel on the market covers 12, 24, 48, and 96-port configurations.

Cat5e and Cat6 patch panel

Can I Use Cat5e Patch Cable With Cat6 Patch Panel?

In fact, there isn’t much difference between these two types of patch panels. What matters is the difference of wire gauge specified between Cat5e and Cat6 patch cables. It’s well known that both Cat5e and Cat6 patch cable contain four twisted pairs of copper wires, but Cat6 patch cable is thicker than Cat5e. This is because there is a longitudinal separator inside Cat6 patch cable which isolates each of the four pairs of twisted wire from the others, reducing crosstalk and allowing for better signal. And another reason is that Cat6 patch cable utilizes copper conductor which has larger diameter than that of Cat5e patch cable. So you may ask, if I use Cat5e patch cable with Cat6 patch panel, will it be too loose? Slightly Yes, but electrically it will still make contact and work well.

Can I Use Cat6 Patch Cable With Cat5e Patch Panel?

Sometimes you may also encounter the situation where you want to use Cat6 pacth cable with Cat5e patch panel. The content above has mentioned that Cat6 patch cable is thicker than Cat5e patch cable. In spite of the size difference between them, the fact is that Cat6 patch cable is backward compatible with Cat5e patch cable. Therefore, you can feel free to use Cat6 patch cable with Cat5e patch panel.

Note

When plugging Cat5e patch cable on a Cat6 patch panel, the Cat5e patch cable is small enough that it is possible to get what looks like a good connection. However, the contact is not actually good or the plug is not in the right place. While plugging Cat6 patch cable on a Cat5e patch panel, the larger wire may end up bending or even breaking the port. Therefore, in both cases, it is necessary to install and test each connection carefully to make system work fine.

Conclusion

In theory, doing like these is not recommended. Using Cat5e patch cable with Cat5e patch panel or Cat6 patch cable with Cat6 patch panel will get the best performance. FS.COM provides both high-density Cat5e patch panels for Fast Ethernet applications and Cat6 patch panels for 1G/10G Ethernet applications, such as 24 port Cat5e patch panel, 48 port Cat5e patch panel, 24 port Cat6 patch panel, 48 port Cat6 patch panel, etc. In addition, Cat5e shielded patch panel, Cat5e unshielded patch panel, Cat6 shielded patch panel and Cat6 unshielded patch panel are available.

Things You Have to Know About Wireless Network

Nowadays, network has become a part of our daily life. We get used to the behaviour that we turn to Internet for help to solve a problem or we look through the website to know what happened around us, just like we go to bed at night. Being able to get access to the network is important for us. In the past, there was only wired network. But now, there is wireless network which makes it more convenient for us to surf the Internet. We know that a wireless network is very similar to a wired network with one big difference: devices don’t use Ethernet network cable to connect to the router. Instead, they use radio wireless connections called Wi-Fi (Wireless Fidelity), which is a friendly name for the 802.11 networking standards supported by the Institute of Electrical and Electronics Engineers (IEEE). We know that access point (AP) is a central device that is common used in wireless network. But sometimes we hear something like Wi-Fi range, frequency band or Wi-Fi standard. Do you know what they refer to? This article is going to introduce things you have to know about wireless network.

Wi-Fi Range

The Wi-Fi range refers to the coverage area of an access point’s Wi-Fi signal. Generally speaking, in a good and stable wireless network, the maximum distance for wireless device to receive Wi-Fi signal can reach about 150 feet from the access point. However, this distance will change based on the capability of access point. In addition, there are some other factors that will have an impact on the performance of Wi-Fi signal, such as the power of the devices involved, the environment, the Wi-Fi standard and so on. Among them, the impact of Wi-Fi standard is relatively large, and it will be introduced in the latter part of this article.

Frequency Band

The frequency band refers to the radio frequencies used by the Wi-Fi standard: 2.4 GHz and 5 GHz. The 2.4 GHz and 5 Ghz bands are currently the most popular, collectively being used in all existing network devices. Generally, the 5 Ghz band delivers faster data rates than 2.4 GHz band, but its Wi-Fi range is a little less than that of 2.4 Ghz band. Depending on the standard, some wireless routers use either the 2.4 GHz or the 5 GHz band, while others that use both of these are called dual-band wireless routers, such as Linksys DD-WRT WRT1200AC.

Wi-Fi Standard

The Wi-Fi standard determines how fast a wireless network can be and how much signal area it can cover. To understand what the Wi-Fi standard is, you have to learn about the development history of Wi-Fi standard.

Wi-Fi Standard

802.11b: This was the first commercialized wireless standard. It offers a top speed of 22 Mbps and operates only on the 2.4 GHz frequency band. The standard was first available in 1999 and is now totally obsolete.

802.11g: Introduced in 2002, the 802.11g standard marked the first time wireless networking was called Wi-Fi. The standard offers the top speed of 54 Mbps but operates on the 2.4 GHz band. It is also becoming obsolete.

802.11n or Wireless-N: Available since 2007, 802.11n has been the most popular Wi-Fi standard, with lots of improvements over the previous ones, such as making the range of the 5 GHz band more comparable to that of the 2.4 GHz band. The standard operates on both 2.4 GHz and 5 GHz bands and it offers a top speed of 600 Mbps.

802.11ac: Sometimes referred to as 5G Wi-Fi, this latest Wi-Fi standard operates only on the 5 GHz frequency band and currently offers Wi-Fi speeds of up to 1,750 Mbps (or even faster with latest chip) when used in the quad-stream (4×4) setup. The standard also comes with the 3×3, 2×2, 1×1 setups that cap at 1,300 Mbps, 900 Mbps and 450 Mbps, respectively.

Network technology has move forward without stopping its step. And now there are 802.11ad and 802.11ax Wi-Fi standard for wireless network. Besides, the later standards are backward compatible with the earlier ones.

Conclusion

Network is of close link with our life, bringing us incomparable convenience on our life and work, especially wireless network. It is necessary to know some knowledge about wireless network. I hope this article is helpful for you when you choose wireless devices and solve some problems related to wireless network. To build a good wireless network, FS.COM provides quality Ethernet network cable, such as Cat5e cable, Cat6 cable and Cat7 cable. Also, you can find wireless access point here.
