How To Find the Best Ethernet Cables

Ethernet Cables or Plenum Cables are a prevalent type of cable you will frequently find in a house office setting, or possibly a commercial environment. They are available in many lengths and can also be utilised in multiple places. For the individual who likes to travel frequently, it is essential to consider that Ethernet Cables often carry an electrical power supply with them.



PVC Cables (or PVC Cables) will be the second most popular and least expensive form of indoor Ethernet Cable. It's ideal for enclosed spaces where airflow does not share with regions of individual residence. These kinds of indoor Ethernet Cables come in a variety of colours and lengths, which will make it easy to find the ideal match for your project. It makes plenum Cables out of an inner core and then coated in a PVC jacket. It is excellent for both indoor and outdoor environments and can be comfortable at a variety of different regional retailers.


High-Quality Fiber Optic Cables


Fibre Optic Cables is an excellent option for the person who likes to have over. One cable within reach of one another. It's perfect for long-distance travelling or those who need a high quality of the sign. These types of indoor Ethernet Cables are more expensive than the other two. You might not find them locally, but you should find them at a retailer. They're also a better choice for the home user since they don't have to have multiple cables installed to reach every region in question.


There are plenty of other types of Ethernet Cables, including Copper Braid Cables, FireWire, Nylon Cable and Fiber Optic Cables. You may see them in just about any place at a home electronics store. The ones which you choose depend on your precise requirements and where you live.


Do not forget that if shopping for Ethernet Cables, you might find that the best deals are usually found if you shop at retail shops offering free shipping.

Wired or Wireless: How to Choose Your Connection Type

Millennials know that Wi-Fi is superior no matter what you say. In 2019, you can play console-level games without a single cable, or even an actual physical console. You can put up a video of activity now while doing that activity, without a huge workstation setup.

We want to have seamless smart home routines and over the air software updates for our cars. We also don’t like it when our video buffers or when we experience friction in our media exchange. To make sure Wi-Fi is consistent, fast and available everywhere, a completely new industry has sprung up of Wi-Fi nodes. They help eliminate Wi-Fi dead zones.


We tend to do forget sometimes that Wi-Fi does not just exist, it’s available in the air. It comes from the router we have hidden in our closet or shoved behind the cabinet.

At the end of that router, there is an Ethernet cable. One that you do have to occasionally replace. The nature of this Ethernet cable depends on whether your internet needs are for your home or office. While there are multiple iterations of this cable, two of them are the most popular: Cat5e cable and Cat6a cable.


The main difference between them is the speed and reliability of the internet connection. This is not to say that either is bad. Cat5e cable is perfect for household uses, whereas the Cat6a cable is perfect for office-related use.


Let us walk through a general home and office use case scenario:


Home Internet Use:


Homes vary in sizes, but if you take a standard three-bedroom house, it is likely that just one router is not going to do the trick. This is where Wi-Fi nodes come in. You can use one Cat5e cable for the main router to connect to your modem, and then add the nodes simply with their power plugs around the house. This will create a mesh Wi-Fi network in your house, making connectivity that much better in all corners of the house. Say goodbye to buffering!


In a home, internet usage is generally that of entertainment or education. With a reliable connection, that is a result of this cable and the mesh network, your Wi-Fi can be better. This means you can stream movies without buffering at high resolutions, play games online seamlessly as well as take online classes and attend webinars.


For Office Internet Usage:


Now if the office only had two, three or even five devices that needed to connect to the internet, the obvious choice would be Wi-Fi. But if that is not the case, and you need to get internet access to more devices, then go with wired connections. Offices require seamless internet as their work depends on it. You should go with the Cat6a cable as it works at a bandwidth of 250 MHz.


You need to have an Ethernet cable per computer. But computers are not the only thing that requires an Ethernet cable in an office. Depending on the kind of company, it might have to maintain servers. This is where the use of the Cat6a cable really comes in handy.

The speed it gives can give instantaneous connections for over 10 people at the same time.


The difference in such Ethernet cables is not that one is superior to the other, but that their uses are generally different. There is no harm if you use these cables interchangeably, but it might affect the productivity of the office a little bit.


The advantage of such a wired connection is that they are speedier, and the obstacles that apply to Wi-Fi, don’t apply here. These obstacles include the placement of the router, walls, trees, and other objects. Wired connections don’t have such issues.


As opposed to wired connections, when you want to go with Wi-Fi, you should take care of the wiring of the router. And these cables are top of the line right now and will be for the coming wave of extensive internet usage over the next couple of years.


At SF Cable, we have Ethernet cables in all varieties, and CAT6a and CAT5e are some of the most popular amongst all. You can get them in a variety of colors and lengths.

4 Things to Take Care of in a Data Center

In 2017, at the Worldwide Developer Conference, in the opening video, Apple showed a very interesting thing. They wanted to highlight the fact that the world cannot be without apps. A data center employee accidentally unplugged the servers to plug in his waterfall, and in doing so, turned off the data center. This turned off all the apps and there was an APP-pocalypse.


What this also highlighted was that without data centers, most apps would stop working! Apps heavily depend on the cloud infrastructure that Amazon, Google and Microsoft (mainly) provide. So the app that you use most could stop working if the data center stopped working.


The data center needs to run perfectly if it is going to be able to deliver that kind of consistency. To ensure that it runs smoothly at all times, you have to keep in mind 4 main things:


1. Cabling

  • Structured Cabling
  • Unstructured Cabling

2. Cooling
3. Security
4. Electricity


Let’s look at all of these metrics in detail:


1. Cabling:


Servers require bulk Ethernet cables and there are two ways to set the servers up in terms of cabling:


Structured cabling: This type of cabling uses predefined points of connection and pathways, based on already existing standards. The bandwidth required by the system determines the kind of cabling to use when it comes to structured design. You have to label the cables accurately. Structured cabling is a well-organized system.


Unstructured cabling: This kind of cabling is Point-to-Point cabling. It does not have defined connection points or pathways. The airflow in this type of system can be restricted and this can create cooling issues. Because it is unorganized, it can be difficult to move or add servers to this system, and it increases the downtime in case of issues that need fixing.


2. Cooling:


In a setup, that has a huge number of servers: Ethernet cables, optic cables, and constant flow of electricity, it can get plenty hot. Excessive heat is not a good thing in such close quarters. So to maintain a cooler atmosphere in a data center, you can scale back on lighting. Once set up, it only requires little daily changes, so less lighting or special lighting, depending on the frequency of humans going in, can help in maintaining the temperature. Natural ventilation can also help to some level but you would need to outfit dedicated cooling units per a certain number of racks, as well as manage the overall environment. With a smart environmental management system in place, you can make sure that your servers shut down before succumbing to fluctuations in temperature.


3. Security:


A data center houses sensitive data about apps, customer data, etc. Therefore, it is imperative that you take measures to maintain tight security. You should install security cameras in a way that you can see all corners and aisles. They should also be of the kind that let you see any activity in low light. However, it is not enough to protect it against data breaches and human errors. You also have to have measures in place in case of natural calamities. Take into account the design of the infrastructure so that it can withstand earthquakes, floods, etc. These precautions can save you a massive loss of data and expense in the long run.


4. Electricity:


Just like you have to account for other calamities, you also have to keep in mind that electricity can stop without notice, for multiple reasons. This is why you have to have a backup power supply in case your electricity fails. This way your backup power kicks in before anything goes majorly wrong.


These are the four most important things that you have to take care of in a data center. Apart from these things, there are other equally important but second level details to keep in mind, such as what Ethernet cable you want to use, how many server racks you want to have, the material for the infrastructure, the lighting you want in the data center, etc.


The world needs apps, and apps function if you take care of these four things in a data center. Keeping it connected to the internet with the right Ethernet cable is the most important thing.

Cat 7 vs Cat 8 Cables: What's the Difference?

Supposedly, you have to install data cables for your newly built house. But don’t have any clue about them. And we all know that it can get overwhelming with the variety of ethernet cables available in the market such as Cat5, Cat5e, Cat6, Cat6a, Cat7, cat8, and so on.


So, if you are selecting the cable for your place then it is important to understand their features and capabilities.


Presently, Cat 7 and Cat 8 cables are marking their presence in the market with their efficiency and compatibilities with other ports. And complicated questions are bound to arise like if using Cat 8 with standard Cat 7 would work or not.



To answer such questions before they arise, let’s understand Cat 7 and Cat 8 in details including their main differentiating point.


General Information:


Cat 7 Cables:


Category 7 cable known as a Cat7 or Cat-7 cable is used to cable the infrastructure of Gigabit Ethernet. It offers up to 600MHz. A perfect choice to cable your smart home. After cabling, you can even check for the automation ideas. It supports high-speed ethernet communication up to 10 Gbps. These are backward compatible with Cat6, Cat5, and Cat5e categories. It provides a 100-meter 4-connector channel with shielded cabling. They require twisted wires to become a full shield system. Such systems are known as screen shielded twisted pair (SSTP) or screened foiled twisted pair (SFTP) wiring. It eliminates alien cross-talk with improved noise resistance. It allows users to get higher speeds with longer cables.


Cat 8 Cables:


Category 8, Cat8 cable or Cat-8 cable is an ethernet cable which is a different type of cable standing apart from the previous cables. It supports a frequency of up to 2GHz(2000 MHz). It is limited up to the 30-meter 2-connector channel. It requires shielded cabling as well. The major point to consider is that it can support a speed of 35 Gbps or 40 Gbps. Overall, its physical appearance is similar to lower category cables. They terminate in RJ45 connections or non-RJ45 connections. It is compatible with all its backward versions. You can use it with the standard connectors of previous versions such as Cat-7.


Cat 7 Vs Cat 8 Comparison


While comparing these cables transmission frequency and cabling length are of great importance. Here is the detailed comparison:




Cat7 cable offers performance up to 600 MHz Whereas Cat8 offers up to 2000 MHz


Cabling Length:


The maximum cabling length of Cat 7 network is 100m with 10 Gbps. Whereas Cat8 is limited to 30m cabling length with 25 Gbps or 40 Gbps.




If we consider pricing, Cat 8 cables are more expensive than other standards considering its unique features.




Both the cables have shielding cable construction. Cat 7 cable offers extensive shielding for reduced attenuation. And they require special GigaGate45 connectors to attain the full advantage of its higher performance features.


As Category 7 cables offer 1 100-meter 4-connector channel with shielded cabling, even if it operates at a higher frequency, there would be no improvement in data rate. Because 10GBase-T is still the fastest twisted pair-based data rate recognized by IEEE 802.3. Hence, even if a Category 7 cabling system is there in your network, any available active equipment would have limitations up to 10-Gbit/sec performance. It is not a recognized category by TIA.


Category 8 cables require shielded cabling. Unlike Cat5e to Cat6A, it does not come with an unshielded twisted pair. The most likely cable construction for Category 8 will be 22-AWG S/FTP cabling.


Features Summary:



Pros And Cons:


Cat 7 Cables:


  • Pros – Shielded with a higher operating frequency than Cat6a cables.
  • Cons – They are a bit expensive. They require 40 to 60% more space to contain the cable and different connections. Their testing is trickier and requires modern test equipment. There is no real speed advantage over a good Cat6a system.


Cat 8 Cables:


  • Pros – The fastest copper network is available for any distance.
  • Cons – Due to different connectors, they are not compatible with cat5e and cat 6 cables. These cables are expensive than the previous versions.


Pick Your Choice!


These cables are modern-day products designed to cable appropriate environments. Based on the feature comparison, you can pick your choice to make a that fits your requirement and helps you render maximum data speed.


Here is a detailed overview of the differences between Cat 7 and Cat 8 cables. Understand their features and their use cases for a high-speed network system.

The Future of Network Cabling: Fiber & Copper Together

With the technological advancements & increasing internet speed raises a question as to whether to use traditional copper as the physical interconnector or upgrade to fiber to support these higher speeds.


In this blog post, we are going to see the main difference and consequences of using both on the same platform.


Size And Space:


The main difference will be fluctuation in size and weight. Everyone has seen a traditional Cat5/Cat6 and a fiber cable. The clear difference here is that a duplex fiber optic cable provides 25 percent space savings and 50 percent weight savings over shielded bulk cat5e cable. Moreover, optical fiber cables are lighter, thinner, and more efficient than their copper counterparts. However, it is important to note that fiber cables are a bit more fragile and require special tools to terminate connections.


Transmission Speed:


Traditional Cat5 twisted pair copper cables support a transmission rate of 100 Megabits per second. On the same side, Cat 6 supports an impressive rate of 10 Gigabits per second up to a distance of 300 feet.



Whereas new fiber cables and new transmission protocols are booming each and every day. For mobile military platforms, fiber can support anywhere from 100Mbps up 10 Gbps. However, in data centers and service provider interconnects, fiber support the speed of 40, 50, 75, and 100 Gbps. And you can even see 400Gbps speed tested and implemented.


Signal Loss:


One of the major disadvantages of copper bulk ethernet cable is that they experience mass signal loss over long distances. If we look at the effective limit of a copper run, that is about 100 meters. Other distances longer than that require ethernet switch, ethernet extender or media converter that can basically link two runs of copper together. Another way is to terminate the copper run and add a link to a fiber connection for the additional distance.


On the other hand, fiber optic cables can run without significant signal loss over longer distances. As new technologies are constantly coming ahead, a single mode fiber can support up to 100 Gbps up to 10km without any significant signal loss.


EMI And Cross Talk:


Copper cabling is responsive to crosstalk and both radio frequency and EMI as it transfers an electrical signal. Cat6 Ethernet cables lessen the interference, but it does not escape it. The interference can be controlled with several measures which include an internal spline to separate the twisted pairs.


As the fiber optic cable doesn’t carry electricity but light, it is immune to the interference problem which can plague copper cabling.


Environmental Concerns:


Copper cables can potentially be a fire hazard in the long run. Because there is an electrical current passing through a plug which can wear over time. Whereas there is no electricity involved in the transmission of fiber optic signals, there is no concern of fire. Many users believe that fiber’s size and weight make it less resistant to the installation. But the fact is fiber is more durable with a higher tension limit than copper and stands up to environmental changes.


But why till date many of the platforms still use traditional bulk cat5e cable/cat 5 cables?

  • Till the date, fiber was an expensive cable. The overall economics of fiber has changed globally over the years; hence, the cost is becoming a less mitigation factor.
  • Fiber is sensitive metal. It reacts on twisting and kinking. It is a complex install. It changes rapidly with newer fibers, connectors and installation tools.
  • There is a huge installed base of copper, which is here to stay. Hence, many of them feel that the change of copper cables to fiber is optional.
  • A huge number of devices which need to connect still have only copper connector interfaces.


In the meantime, there are various ways to handle this situation. Many bulk ethernet cables and switches support the connection of copper as well as fiber. This way, devices connected with either physical medium will be able to communicate with each other. In such a scenario, physical media converters can act as a bridge between the two media offering a range of configurations which support fiber in/copper out or copper in/fiber out or many other configurations.


When it comes to big enterprises and data service providers, they have the way to replace copper with fiber in almost every new deployment. However, mobile and airborne platforms lag behind this evolution for many reasons. Speed requirements are not that much in demand, but field repairs and deployments are often harder. And finally, there comes the cost factor. We can expect to see the continued evolution from copper to fiber, but at a controlled pace. In the meantime, we can continue seeing the physical intermediary technologies that co-exist for many years to come.


Though fiber cables have replaced the traditional ways the copper cables used to work, there is a way they can co-exist. Find out how
