10GBASE-T Cabling Vs. 10G SFP+ Cabling in 2017

When it comes to 10G network, we usually make a choice between 10GBASE-T cabling and 10G SFP+ cabling. In fact, many people still prefer 10G SFP+ cabling that uses SFP+ DAC cable, because they think it matches better for the requirements and emerging trends of today’s data center. Now the 10G network is quickly becoming mainstream, especially on consumer desktop systems. That means the cost of 10GBase-T switches will need to come down. Also, other “IOT” home components that decide to offer 10G will probably go for 10GBASE-T, such as game consoles, streaming boxes, etc. So, do you still recommend 10G SFP+ over 10GBASE-T nowadays for network deployment? This article will discuss this topic.

10GBASE-T Vs. 10G SFP+

Vote for 10GBASE-T
  • The 10GBASE-T ports are physically smaller which is important for non-data center devices. They are also easier to use. You just plug in an ethernet cable and it works. No need to deal with optical transceiver compatibility and all of those problems.
  • 10GBASE-T cabling is backwards compatible with 1G ports which will still be used for things like IPMI and other low bandwidth devices. You could just get one 10GBASE-T switch and connect up everything you have to it. Going with 10G SFP+ makes it difficult to find something that juggles enough of both kinds of ports for all of your 10G and 1G devices.
Vote for 10G SFP+
  • 10G SFP+ is better for future-proof cabling system. You can migrate to 40G QSFP+ smoothly and keep the existing cables. Even OM4 can do 100Gbps up to 150 meters. It is not known if Cat6a, Cat7 or even Cat8 will be able to pull off anything above 10Gb. And this will be stuck at 10G for quite some time.
  • 10G SFP+ interface that has been widely deployed for 10G ToR switches continues to use less power, typically less than 1 W per port. It also offers better latency—typically about 0.3 microseconds per link. While 10GBASE-T latency is about 2.6 microseconds per link due to more complex encoding schemes within the equipment.
  • 10GBASE-T switches are still expensive and there is a very limited choice of those that actually work. Also 10GBASE-T NICs add a premium over 10G SFP+. From a cost perspective, it is cheaper to go the 10G SFP+ cabling since you can find so many used 10G switches for deals, along with decent NICs. In addition, there is more support, driver wise for 10G SFP+ NICs than 10GBASE-T.

By comparison, we find that if flexibility and scalability are more important, 10GBASE-T cabling is a better option; but if power consumption and lower latency are critical, 10G SFP+ cabling may be more suitable. We also find that the cost of 10GBASE-T cabling is no longer in the ascendant. If 10GBASE-T want to acquire an absolute advantage, the primary goal now is to get 10GBASE-T cheaper and more power efficient and bring the cost way down so it can finally replace Gigabit as the next base level networking.

A Third Choice

If you do not have to choose vanilla or chocolate, you could have both 10GBASE-T and 10G SFP+ in the same switch, such as Ubiquiti EdgeSwitch 16 XG and UniFi Switch 16 XG. Both of them feature twelve 10G SFP+ ports and four RJ45 10GBASE-T ports to efficiently deliver and aggregate data at 10G speeds. But some people point out that the 10GBASE-T ports on the Ubiquiti switches actually don’t work reliably at 10Gbps speed. Therefore, before you buy it for those four RJ45 10GBASE-T ports, you have to make sure that they can work without issues. Here is a figure of them for you.

Conclusion

If you were building out a 10G cabling system from scratch today, which technology would you choose for your 10G network connectivity? Both 10GBASE-T cabling and 10G SFP+ cabling have their own advantages. And both of them occupy an important position in the future of network design and best practices. As for which one to choose, it all depends on your specific need. FS.COM can provide cost-effective solution for your 10G network deployment, such as Cat5e bulk cable, 10G SFP+ transceiver, 10G SFP+ DAC cable, 10GBASE-T SFP+ Transceiver and so on.

All About Cat7

Network has become an indispensable part of our daily life. Many homes and businesses today deploy network with either a wired network connection or a wireless connection, and these two network connection methods have their own advantages: wired connection is typically faster than wireless connection and has lower latency; while wireless connection makes it easier to get access to the network from nearly any convenient location. As network technology has kept stepping forward, these two types of network hardware also continue to advance, satisfying the requirements of users. Take wired connection for example, now a newer cable category is Cat7 ethernet cable. This article will focus on Cat7 and share the advantages and disadvantages of Cat7 cabling.

Overview of Cat7

Cat7 ethernet cable is not currently recognized by TIA/EIA, but it is designed to support 10G Ethernet with distance up to 100 meters. It can offer transmission frequencies of up to 600 MHz, which is 6 times larger than Cat5e and 2.4 times larger than Cat6. The Cat7 ethernet cable contains four twisted copper wire pairs, just like the earlier standards, and shielding has been added for individual wire pairs and the cable as a whole. In addition, Cat7 ethernet cable is terminated with GG45 (GigaGate45) connector, which is still compatible cat5e cable and cat6 cable with RJ45 connector.

Advantages And Disadvantages of Cat7 Cabling

Though Cat7 ethernet cable is a newer cable category, it is not the best choice for all network deployment. Why? Keeping reading and you will find the answer in the following part.

Advantages
  • Cat7 has higher bandwidth of up to 600 MHz, which is 6 times larger than Cat5e (100 MHz) and 2.4 times larger than Cat6 (250 MHz).
  • Cat 7 has an overall shield as well as individual shielding of every pair. It performs better to protect against outside interference. Therefore, it is suitable for installing in strong RFI & EMI environment.
  • Cat7 is thicker, more bulky, and more difficult to bend.
  • Cat7 is regarded as the most durable cable and has a longer lifespan of fifteen years than cat5e cable and cat6 cable.
  • Cat7 is compatible with preceding Ethernet cable standards like Cat5e and Cat6. as a result, users can move Cat5e cable or Cat6 cable from existing copper based LAN and install Cat7 without having to change the existing electronics.
Disadvantages
  • Cat7 ethernet cable is not currently recognized by TIA/EIA. It is not a solid, established industry standard.
  • Cat7 is very heavy. Individual pair and overall shielding increases the overall weight and size of Cat7, which makes it not an job for Cat7 cabling. Larger & stronger pathway and more stringent bend radius (100 mm or 4 inch) are required.
  • Cat7 is more expensive. Individual pair and overall shielding also means higher labor costs and more work towards cable termination.
  • Cat7 cabling may cause ground loop problems. If both ends of the cable are connected to ground, it will lead to ground loops which are a major cause of noise, hum, and interference in audio, video, and computer systems. They can also create an electric shock hazard, since ostensibly “grounded” parts of the equipment, which are often accessible to users, are not at ground potential.
Conclusion

For home network deployment, it is not a great option, because it is more expensive and Cat7 cabling is complicated. However, Cat7 is suitable for the place where needs high speed data transmission and is high EMI environment. Therefore, in order to get a successful network deployment, you have to make a careful plan, be familiar with environment, confirm the requirement of network deployment and choose the right transmission media.

Advantages and Disadvantages of Wireless Access Points

With more and more wireless Internet users, wireless Internet access has become a trend. A wireless access point (AP) is ubiquitous no matter in a family or a large department store. However, everything is imperfect, since advantages are always followed by disadvantages. This post will interpret the advantages & advantages of wireless access points respectively.

Advantages:
1. More users access

An ordinary wireless router can only support 10-20 users access, while AP is able to allow over 50 or even hundreds of users access, and what’s more, it has stronger ability to send and receive signals. Especially in a large area needing wireless coverage, an AP has more advantages than a wireless router.

2. Broader range of transmission

Generally, the range of signal transmission that a wireless router can cover is just dozens of meters, and if beyond this range, signal will be lost. Nevertheless, an AP can cover further distances, up to 100-300 meters, and the increase of wireless access point will extend signal coverage proportionally, which enables users to roam freely in the network. Especially for enterprises, their office space is usually larger, and even some need to communicate across the buildings, and the number of users accessing the network is so large that they need a larger wireless network coverage, thus avoiding management of cabling.

3. Flexible networking

It is known that except home networking, wireless networking in commercial locations often involves the use of many wireless devices, and different networking patterns should be adopted based on the environment and requirements. The networking mode of the wireless router is relatively single with low flexibility. On the contrary, an AP has a variety of modes for you to choose, which meant to be very flexible, such as Simplex AP, Wireless Client, Wireless Bridge, Multi-point Bridge, etc. and it can be managed in a centralized way with the cooperation of wireless AP controller.

4. Multi-AP interconnection

The enterprise can design the wireless program flexibly according to its actual situation. Multi-AP interconnection can give full play to its advantages. Multi-AP applications are typically found in businesses but rarely exposed at home. In the business, the coverage of single AP is limited, so in order to extend the coverage of wireless networks and allow clients to roam seamlessly in the network, multi-AP interconnection will be a favorite for an enterprise.

multi-APs interconnection

Disadvantages:
1. High cost

Some people think that wireless AP is a little bit expensive, because for enterprises, when the scale of enterprise wireless network is larger, the more wireless APs are needed, thus the higher cost that enterprises will undertake. So the priority for an enterprise is to control cost, which leads many people to be reluctant to use wireless AP, instead, they prefer using home wireless routers with lower performance.

2. Inability to be used alone

Now, many people would firstly think of wireless routers instead of wireless AP at the mention of building wireless networks, unless it’s a large hotel, or public places. The main reason is that a wireless AP can’t be used alone, can’t be directly connected to ADSL (Asymmetrical Digital Subscriber Loop) modem and it needs to be used in conjunction with other equipment like switches, controllers, ethernet hubs, etc. Therefore, many people would find it very troublesome and less convenient as a wireless router.

WiFi-AP can't be used alone

3. Poor stability

Poor stability is aiming at cable networks. Wireless networks take air as transmission medium while cable networks take cables as transmission medium. It’s not difficult to know that the cable network is faster and more stable than wireless network. Wireless AP only functions well when failing to build a cable network.

Conclusion

Wireless AP and wireless router are facing different targeted groups, a wireless router is aimed mainly at home users and students with low cost and good performance, and it’s able to meet the basic needs of the general family users. Wireless AP is mainly for business users, and its transmission range is wider and broader, it supports more users access, and has stronger signal sending and receiving capability. At the same time, it also has better safety performance, of course, the price will be far more expensive accordingly.

Importance of Plug Boot For RJ45 Cables

Ethernet cables with RJ45 connectors are widely applied to our life. When choosing the RJ45 cables, you may discover that these cables have different appearances of their cable plugs. For example, some cables will have a rubber thing on the clip while some don’t. Why do RJ45 cables have such design and what is the function? This post is going to present the basic knowledge about the special design.

What Is Plug Boot?

This rubber thing is known as plug boot. A booted cable has the plug boot on the cable end of the connector. You can find two main types of boots on the market. One is the separate boot that can be purchased individually to put on the cable, and the other is the injection molded boot to be bought together with the cable. Of course, the latter is more stronger to provide support for the cable when the connector is being pulled out of a switch, patch panel or other devices. Non-booted cables will not have the plug boot as the protection, which are easier to be damaged.

Functions of Plug Boot

Generally speaking, the boot design has two purposes. Firstly, the plug boot can prevent the connector clip from flipping up or even breaking off from the cable. When the plastic clip is broken, cable won’t be able to firmly connect to the network which will then interrupt the data transaction. Secondly, using the booted cable is also a protection for your own nails. Because the clip is slim and small, it is easy to stick into the nails during the installation or removal of RJ45 cable. Hence, for the better protection of both cable connector and your nails, Ethernet cables with plug boots are a great solution.

Several Types of Boots

If you want to buy the booted cables, you should also consider which type of boot is best fit for your network since plug boot also has different constructions. Here will introduce the common types of plug boots.

Standard Boot

The standard boot looks like the half of a dome. It protects the clip on all sides and prevents it from snagging or breaking off. This is the type widely applied to cable installation through floors or walls.

Molded Boot

Molded boot does not protect the locking clip. It is easy to plug in and out. This type of boot is suitable for hard-to-access space where cables are seldom plugged or unplugged.

Snagless Boot

Snagless boot has a small flap to protect the RJ45 clip. It is often used in applications where there are high insertion cycles in easy-to-access space.

snagless boot

Slim Boot

Slim boot has a 28% reduction in diameter than the snagless boot. It offers the minimal protection and is easy to plug or unplug. This type of booted cable is usually seen in high-density applications.

No Boot

Non-booted RJ45 cable is much easier for plugging or unplugging, but the whole connector is exposed with no protection. This type is typically used for applications that don’t require frequent unplugging.

Conclusion

In summary, if you want to have better protection for your Ethernet cables, using plug boots is an ideal solution. If the application does not demand too much cable shifting, non-booted cables are also acceptable. No matter which type of RJ45 cable you choose, the decision must be made according to your own project.

Guide to Build Up Home Network

Since network has been ubiquitous in today’s world, building it into our home seems to be necessary when moving into a new house. However, millions of households are haunted by the terrible cabling mess. Cables are usually tucked into corners, tangled around the ceiling or jumbled behind devices. If you want these problems to be solved, a good plan for home network is a must. Have you ever thought about setting up home network all by yourself? This article can be the guidance to the beginners.

Advantages of Good Home Network

A good home network is beneficial to the visual neatness. House will be more tidy when less cables are exposed to the surface. Most wires will be installed through the walls. Possibility of cable mess is greatly reduced and you don’t need to be nervous about tripping over by the cables. Constructing a good home network also increases the value of the home. If the house is for sale in the future, a built-in network can certainly raise the price potentials. In addition, when setting up the network, you can add some aesthetic designs to your house like painting the wall into a new color or moving wall plates to appropriate places.

Different Network Connections

There are generally three types of home network connections. Choosing a suitable type for the network is also important.

Ethernet/LAN

Ethernet or LAN network uses physical cables to plug into the LAN port of router or switch. The speed for Ethernet cables can reach up to 1 Gbps. The cable length usually runs up to 100 meters without any influence to performance. Using a wired network is more secure and reliable. However, if you want to totally get rid of the cabling mess, there are better alternatives.

wired network

WiFi/Wireless LAN

People nowadays are familiar about this wireless network. It is the network that operates through radio waves without any wires. The latest 802.11ac standard defines the WiFi network for the maximum of gigabit speed. Wireless network allows for easier access to mobile devices and is simple to be set up. However, the signal also has a limited range and is easily interfered by other devices or buildings.

wireless network

Power Line

Power line network, known as Ethernet over Power (EoP) is carried through the existing wiring. With the help of adapter plugs, it can be connected to small devices by standard Ethernet cables. It is a good option when installing traditional network cabling is not possible but you want better performance than wireless.

Components Needed for Home Network

Central hub, Ethernet jack, wall plate and Ethernet cable are some basic components for the home network. Technically, a basic four-port switch could accomplish your goals in the central hub. Ethernet jack makes the installation more professional and allows for easier connection with wall plate. Wall plate also provides an easier and stable location for cables to plug into. Of course, Ethernet cable is indispensable and should be selected according to your needs.

How to Expand Home Network

When Ethernet ports are running out on the router, you can buy a new one to add more ports so as to expand the wired network. As for the wireless network, the problem is always about the range of signal coverage. You can try the commercial WiFi extender, or use metal can to focus the antenna in a specific direction.

Conclusion

Many homes are now building up networks into their places. A wonderful home network can provide you with better online experience. This post only offers some basic knowledge about home network. If you are unprofessional, please consult the specialists first before starting the construction.
