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.

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.

Things You Need to Know About Home Network

Network has become an indispensable part of our daily life. If you have a computer at home, I’m sure that you are not unfamiliar with home network. In the past, there was only one way for home network deployment—wired network. However, the pace of network technology development has never slowed down, and now, there is wireless network, which makes it more convenient to get access to the network. As we are in wired network or wireless network environment every day, it is necessary for us to know something about network, especially home network. This article will introduce some basic knowledge about wired network and wireless network.

home network
Wired Network

In wired network, there are two important devices, one is router and the other one is network cable.

Router

We know that router is designed with several physical ports on the front or back of the unit, such as one WAN (wide area network) port, four LAN (local area network) ports and one power input port. Also, there are some LED lights to display device status. All WAN port and LAN ports are RJ45 interface, so one end of network cable can be plugged into them. But for the other end of network cable, there is one difference between WAN port and LAN port. For WAN port, the other end of network cable is plugged into an Internet source, such as broadband service provider; while for LAN port, the other end of network cable is plugged into the RJ45 port on Ethernet-ready device, like computer. The moment you plug a device into a router, you have yourself a wired network.

Network Cable

As for the selection of network cable used for the connection, either cat5e cable or cat6 cable will be OK. The latest network cabling standard currently in use is cat6 cable, which is designed to be faster and more reliable than cat5e cable. Both of them support data speed at 10Mb/s, 100Mb/s and 1000Mb/s, while cat6 cable is able to achieve 10Gb/s. Also, cat5e cable and cat6 cable can be used interchangeably, For most home usage, what cat5 cable has to offer is more than enough. But if you think about future-proof, cat6 cable is a great option in addition to its high price.

Wireless Network

For wireless network, devices don’t use network cable to connect to the router. Instead, they use radio wireless connections called Wi-Fi (Wireless Fidelity). This is one big difference between wireless network and wired network. The devices used in wireless network don’t need to have ports, just antennas, which are sometimes hidden inside the device itself. In order to build Wi-Fi environment, an access point (AP) is required.

Access Point

An access point is a central device that broadcasts a Wi-Fi signal for Wi-Fi clients to connect to. Generally, each wireless network belongs to one access point. For example, when you hang around some stores, you can see different networks popping up on your phone’s screen and each of them belongs to one access point. For home wireless network deployment, you can buy an access point separately and connect it to a router. Now on the market, a kind of wireless router is available, which is a regular router with a built-in access point. This makes your wireless network building more convenient.

Conclusion

In a typical home network, there are generally both wired and wireless devices, and they can all talk to one another. To build a stable home network, it is important to choose quality router, network cable and access point. Though FS.COM does not provide router, you can find high quality network cable and wireless access point. For more details, please visit our site.

Applications of FHX Ultra MTP/MPO Cassettes

Nowadays, data communication technology has developed rapidly. To achieve high speed transmission, it is very common to see complex cabling system in data center, which may even include thousands of fibers. Under such circumstances, saving space in data center is a critical issue. Therefore, fiber optic components or cabling solutions which are characterized by high density will gain the popularity among data center managers. MTP component is such one that can satisfy the requirement. And this article is going to introduce FHX ultra MTP/MPO cassettes and their applications in data center.

Overview of FHX Ultra MTP/MPO Cassettes

MTP/MPO cassette is widely used for high-density cabling in data centers. It is pre-terminated and pre-tested enclosed unit which can provide secure transition between MTP and LC, SC or MTP discrete connectors. And it is usually structured with LC, SC or MTP adapters on the front side of the cassette and MTP adapters at the rear of the cassette. FHX Ultra MTP/MPO cassette has three types: FHX ultra 8F MTP-LC cassette, FHX 12F MTP-LC cassette and FHX MTP conversion module. Here is a figure for you to have a better understanding of these three types of MTP cassettes.

FHX Ultra MTP MPO Cassettes
Applications of FHX Ultra MTP/MPO Cassettes

For application, MTP cassette can be easily found in 10G, 40G and 100G network applications in data center.

FHX Ultra 8F MTP-LC Cassette

Since both FHX ultra 8F MTP-LC cassette and FHX 12F MTP-LC cassette serve to realize the transition from small diameter ribbon cables terminated with MTP connector(s) to the more common LC interfaces used on the transceiver terminal equipment, this part will take FHX ultra 8F MTP-LC cassette as an example. The FHX ultra 8F MTP-LC cassette is structured with four LC duplex (8-fiber) adapters on the front side of the cassette and one 12-fiber MTP adapter at the rear of the cassette, and it is often used for 10G to 40G connection. As the following figure shows, we can also add FHX ultra enclosure and FHX MTP adapter panel to the cabling solution. From the left to the right, four 10G SFP+ transceivers are plugged into four 10G ports on the 10G switch. Then they are connected to LC adapters on the FHX ultra 8F MTP-LC cassette through four LC duplex patch cables. The cassette is installed in the FHX ultra enclosure. One MTP trunk cable connects two MTP adapters respectively on the rear of the cassette and MTP adapter panel. Finally, the 40G QSFP+ transceiver on the 40G switch is connected with MTP adapter on MTP adapter panel through another MTP trunk cable. In this application, 100% fiber utilization is realized. What’s more, the 1U fiber enclosure can house 18 x 8F FHX cassettes or 12 x 12F FHX cassettes, with the total fiber capacity up to 144 fibers for LC interface, greatly saving cabling density.

FHX MTP Conversion Module

The FHX MTP conversion module has several kinds, this part will take 3x MTP-8 to 2x MTP-12 (24-fiber) conversion module as an example. This kind of FHX MTP conversion module is structured with three 8-fiber MTP adapters on the front side of the module and two 12-fiber MTP adapters at the rear of the module. We can use FHX ultra enclosure to hold MTP conversion module. The following figure shows the cabling solution for 120G to 120G connection. Three 40G QSFP+ transceivers are respectively plugged into 40G ports on three 40G switches on both sides. Then the three 40G QSFP+ transceivers are connected with three 8-fiber MTP adapters on the front side of the module through three MTP trunk cables. Finally, two 12-fiber MTP adapters at the rear of two respectively modules are connected through two MTP trunk cables. This cabling solution utilize Based-8 MTP cabling system and achieves 100% fiber utilization. With the use of 1U FHX ultra enclosure, twelve 3x MTP-8 to 2x MTP-12 conversion module can be used in this cabling solution, which creates a 33% spacing-saving upgrading path.

A Closer Look at OM5

We know that for short-reach optical interconnects, multimode fiber is a cost-effective solution. As data centers are constantly moving towards faster speeds and higher densities, the multimode fiber also has evolved over time, from OM1, OM2 to OM3 and OM4 multimode fiber. Now, OM5 is coming. This article will guide you to have a closer look at OM5.

Overview of OM5

OM5, also known as wide-band multimode fiber (WBMMF), is recognized within both the Telecommunications Industry Association (TIA) and International Electrotechnical Commission (IEC) standards. It is designed to support shortwave wavelength division multiplexing (SWDM) which would use 850nm, 880nm, 910nm and 940nm for transferring signals.

OM5

Characteristics of OM5

What makes OM5 different? What are characteristics of OM5? The following part will make a summary.

Size: OM5 fiber is laser optimized multimode fiber (LOMF) of 50 micron core. Therefore, OM5 cabling supports all legacy applications at least as well as OM4, and is fully compatible and intermateable with OM3 and OM4 cabling.

Color: TIA has specified lime green as the official cable jacket color for OM5.

Bandwidth: The operating band of OM5 is from 850 to 953nm and its effective modal bandwidth is specified at the lower and upper wavelengths: 4700 MHz.km at 850nm and 2470 MHz.km at 953nm.

Speed: OM5 can support 40G, 100G and 400G Ethernet by accommodating SWDM. And it is designed and specified to support at least four WDM channels at a minimum speed of 28Gbps per channel through the 850-953 window.

Distance: When transferring signals at the speed of 10 Gb/s, OM5 can achieve 550 meters; when transferring signals at the speed of 40 Gb/s, OM5 can achieve 440 meters; when transferring signals at the speed of 100 Gb/s, OM5 can achieve 150 meters.

Working principle: Since SWDM will enable 40G and 100G over few fiber strands, when using 25GBASE-SR specifications, 100 gigabit OM5 fiber links could be created using 2-fiber 25 gigabit channels on 4 different wavelengths. Similarly, using 100GBASE-SR4 specifications, 400 gigabit OM5 fiber links could be created using 8-fiber 100 gigabit channels on 4 different wavelengths.

Cost: As the matter of fact, OM5 cabling will costs about 50% more than OM4.

Comparison Among OM5, OM4 And OM3

By comparison, it is not difficult to find that there are many differences between OM5, OM4 and OM3.

  • OM5 carries at least 4X more capacity than OM4 over a meter of fiber and carries 5.7X more capacity than OM3 over a meter of fiber.
  • The color of OM5 fiber is lime green, while standard OM3 and OM4 fiber is aqua.
  • The effective modal bandwidth for OM5 is 4700 MHz.km at 850nm and 2470 MHz.km at 953nm. While OM4 is 4700 MHz.km at 850nm and OM3 is 2000 MHz.km at 850nm.
  • For 100 transmission speed, OM5 uses 2-fiber 25 gigabit channels on 4 different wavelengths, while OM4 and OM3 requires the use of 8-fibers via 100GBASE-SR4.
  • OM5 supports transmission distance of 440 meters for 40G SWDM system and 150 meters for 100G SWDM system. While OM4 can only achieve 350 meters for 40G SWDM system and 100 meters for 100G SWDM system; OM3 can support 40G SWDM system with distance of 240 meters and 100G SWDM system with 75 meters.

Conclusion

As a new type of multimode fiber, OM5 fiber does have a breakthrough in some aspects. However, it is not very popular on the market. Maybe because its strength is not prominent. Therefore, for OM5, it still has a long way to go. For 40G/100G network deployment, FS.COM will will keep you upgraded with the latest development of wide band multimode fibers.
