Considerations When Choosing a Topology

Considerations When Choosing a Topology

So what exactly is topology? In general, the term topology refers to one of the most common ways to set up networks and identify how all the devices connect to one another. There are several different ways to organize a network topology, but you have to determine which is best for you first. Each arrangement has its own advantages and disadvantages, and we’ll break those down below. However, before you can begin, check out these considerations when choosing a topology setup.

First of all, why does topology matter anyway?

There are several reasons topology is vital to the success and reliability of your network and ultimately your business. First, you, your business, and your employees deserve to work on a reliable network, and your topology plays a large role in just that. Second, the appropriate topology will increase your network speeds. Third, you can cut costs and maintenance since you won't have as many cables, which will allow you to purchase higher-quality cables in the first place.

The different types of topology

Physical and logical are the two common types of topology setups. A physical network topology includes the physical connectors, cables, maintenance, and more. Essentially a physical topology is the network itself. On the other hand, we have a logical topology, which includes the details of the network setup. You can think of a logical topology as the vision because a logical topology includes a virtual representation of the setup. Since topology setups depend widely on your setup and what you need, there isn’t a universal option for everyone. Below we’ll get into the different setup options.


Sometimes referred to as “line topology,” the bus setup connects all its devices by a single cable running in one direction. The primary benefit of a bus topology is that they have minimal hardware and maintenance because it’s all one cable, which also comes with financial benefits. On the other hand, a single cable can be the culprit for several disadvantages. For instance, running all devices on one cable makes the network prone to hacking, damage, failures, and downtime. In addition, the single cable can result in an overall slower network. The bus topology is great for small businesses that are getting on their feet and have minimal network traffic. However, the bus setup often isn’t considered a long-term solution as you’ll likely need to upgrade as you grow.


As you might expect, the ring topology is set up in the shape of a circle, leaving each device with neighbors. Ring topology is popular for a few reasons. First, the data can transfer in either direction or both directions, but only one device can send data at a time, which significantly reduces what’s called “packet collisions.” On the other hand, just like any of the topologies, ring topology is also capable of downtime. For instance, if one of the devices along the ring goes down, you could potentially lose data or the entire network. Furthermore, the ring can become overwhelmed with data requests since all the devices along the circle share bandwidth, which can lead to interruptions.


The most common topology setup is the star. Unlike the other topology alternatives, the star topology has a central hub that each device plugs into directly. By having a main hub, you significantly reduce your chances of downtime, plus when you need to update a device, you won’t lose the entire network. However, the main disadvantage of a star topology is the central hub; it’s kind of like the old saying of “putting all your eggs in one basket.” If the central hub goes down, you lose your entire network. In other words, maintain the central hub at all costs, and you should be fine.


Relatively similar to the star topology, the tree setup also involves a central hub. However, the central hub then connects to secondary hubs. Many businesses choose to go into a tree topology once they begin experiencing growth because the secondary hubs make expansion rather simple. That said, you run into the same risk as the star setup with a central hub. Not to mention, adding additional hubs can make maintenance more time consuming, challenging, and difficult to manage with extra cables.


The mesh topology has a striking resemblance to the star and ring topologies. The devices remain among the circle, but then additional cabling connects devices in a star-like pattern. The primary advantage to a mesh topology is reliability. By combining the ring topology with the interlocking connections from the star topology, you get one of the most reliable networks available. In addition, the interconnectivity allows you to rest assured that no single device can disconnect the network. This all sounds good so far, right? Well, you knew a disadvantage was coming, and it might be an obvious one. Mesh topologies require a lot of maintenance, and their setup should always be done by a professional.


If you guessed that a hybrid topology combines two or more topologies, you’d be right. Hybrids can combine pretty much any topology. In fact, we’ve already seen a couple: the tree and the mesh are forms of hybrid topologies. The primary advantage of this method is merely the versatility; you can think of hybrid topology as a custom setup. However, these topologies get so complex so quickly that most businesses don’t even use them. In most cases, you spend more money on supplies and installation than you would doing it yourself. The average person would take days or weeks trying to figure out how to set up a hybrid topology.

Your budget

By now, all you’re probably hearing is “cha-ching, cha-ching, cha-ching,” and rightfully so. Some topology setups aren’t too bad, but you have to analyze your budget and find out exactly what you can afford before you choose a topology. Some topologies are much more cost-effective than others. For instance, the bus is much more affordable than the mesh due to all the extra hardware required.

What hardware are you going to use?

Once you’ve worked through your budget, you’ll need to determine which cable you want to use. For the absolute best result, you’re going to want fiber optic cables for their increased transfer speed, but twisted-pair copper cables work fine too. However, the minimal hardware you’ll need includes coaxial cable, Ethernet cable, and possibly even central or secondary hubs, depending on which topology you choose.

Whether you’ve been through this setup process before or not, it’s always a learning process for everyone. However, there are plenty of resources available to help you cross your t’s and dot your i’s and ensure you’ve been through all the considerations when choosing a topology.

How Do HDMI Signal Extenders Work?

How Do HDMI Signal Extenders Work?

Every great entertainment center needs a reliable HDMI cable and signal, so naturally, you might consider using HDMI signal extenders. But how do HDMI signal extenders work? Well, that partially depends on which one you purchase. Several types of signal extenders are available, and each one is set up a little differently. For instance, wireless HDMI signal extenders work surprisingly well, but once you ditch the cables, you begin running into more frequent connectivity issues. We usually suggest a signal extender that connects to your Ethernet cable—sometimes referred to as HDMI over Cat5e or Cat6 extenders. Connecting directly with Ethernet is always going to provide the best connection, assuming you’re using a high-quality Ethernet cable.

As a general rule of thumb, a longer HDMI cable will have a less reliable connection than a shorter cable. The industry believes that any HDMI cable longer than 50 feet should have an extender, as your connectivity and quality begins to deteriorate after that length. However, if you install a quality extender, your image and audio quality will increase. An HDMI signal extender essentially reestablishes the connection at the extension point. It increases the bandwidth of HDMI signals, most notably through a Cat cable connection.

In general, many households won’t need an extender because they typically have shorter cables. Alternatively, if you’re in a commercial setting, there’s a good chance your cables and connection points are longer.

If you’re looking to improve your audio and picture quality, an extender may be in your future. Now that you know how an HDMI signal extender works, you can begin to look for one that fits your needs. However, we’d strongly suggest going for either an HDMI over Cat6 or an HDMI over coaxial, depending on your application. Here at CableWholesale, we want to help you improve your entertainment center and connectivity by providing high-quality cables. Whether you’re looking for 100-ft HDMI cables, Ethernet cables, or extenders, we’re your one-stop shop for all things cables. Contact us today for more information.

Why You Should Use HDMI High-Speed Cables

Why You Should Use HDMI High-Speed Cables

As technology changes and improves, so should all our equipment. Think about it—nowadays, all you really need for most devices is a good HDMI cable. However, some people are still using old HDMI cables when they should be using high-speed HDMIs. Continue reading to learn why you should use HDMI high-speed cables.

Cables adapted with the technology—why haven’t you?

Years ago, most televisions and gaming consoles were connected using RCA cables—you know, the classic red, yellow, and white cables. However, as technology got better, companies came together and developed the HDMI cable. Nowadays, we have televisions capable of producing 3D and 4K video, and an older HDMI cable may not be able to support that technology.

Much better video and audio

People use HDMI cables nowadays for two main reasons. First, they’re simply easier to work with, and they reduce cable clutter because they’re flexible and lightweight. Second, they significantly improve the quality of your viewing experience. If you have a 4K television but you’re using an old HDMI cable, you’re not actually seeing 4K picture quality—you need a modern HDMI cable. Additionally, HDMI cables provide more than just video; they provide audio, too. A newer HDMI cable will give you the sound quality you deserve.

Improved download speeds

Many high-speed HDMI cables come with Ethernet, which is a huge advantage since many televisions connect to Wi-Fi. Of course, your download speeds will depend on your Internet plan and provider, but a high-speed HDMI cable will improve your overall connection. In fact, a high-speed HDMI cable with Ethernet is becoming the norm in most households.

Whether you have a new television or you’re looking into making your first upgrade in years, make sure you get everything you need––including your cables. Many people believe that, because they have a nicer TV or gaming console, they don’t need a new cable. However, that couldn’t be further from the truth, and that’s why you should use HDMI high-speed cables with your next TV or gaming console.

At CableWholesale, we provide our customers with high-quality cables at a fair price. We don’t think your cables should break the bank. We also don’t believe you should have a mediocre viewing experience at home. That’s why we offer high-quality Ethernet cables, coaxial cables, and HDMI cables at all lengths. In fact, we offer everything from 100-ft. HDMI cables to 1.5-ft. cables, so contact us today for more information. Our team will be happy to assist you.

Different Types of Coaxial Cables Explained

Different Types of Coaxial Cables Explained

If you’re anything like us, you’re probably spending a lot more time at home. That usually means that you’re dusting off your old TVs and trying to bring them back to life again––or maybe you already have an entertainment setup. Regardless, you need to ensure that your cables are in good shape along with your devices. One of the most common cables you’ll find behind your television is a coaxial cable. It’s usually a relatively stiff, durable, round cable with a copper pin at the tip. The tip also has a threaded cap that allows you to screw the cable into a TV or satellite box. In other words, you’re going to need a coaxial cable somewhere in your setup. Continue reading so you can learn the different types of coaxial cables explained.


Many professional television installers reach for an RG6 coaxial cable any time they’re installing satellite TV. If you want to get the job done right the first time, an RG6 is the way to go. There are a few reasons that RG6 cables are superior to their coaxial counterparts. First, the cable is an all-around heavier-duty cable. The core is much thicker, which provides a stronger and more reliable connection for your entertainment needs. Additionally, RG6 cables have a thicker insulation and higher-quality shielding. Both of which help reduce external interference (or noise) and protect the core from damage. However, it’s important to note that since the materials manufacturers use for RG6 cables are thicker, they’re much less flexible, so try not to buy more than you need.


Another common coaxial cable is the RG59. While this cable is similar to the RG6, there are some key differences. First, let’s talk about the applications for an RG59. You can certainly use an RG59 cable to connect your television to a satellite box, especially if you’re connecting an older television. However, RG59 cables are commonly used to connect CCTV systems. Anytime you’re in a brick-and-mortar store location and you see cameras inside and outside the building, they’re likely using RG59s to connect. There are two main reasons an RG59 cable is better for CCTV systems over traditional television setups. First, the shielding, insulation, and core are all thinner than an RG6, making the RG59 cable less susceptible to interference. Second, because all the materials are thinner, that makes an RG59 cable much more flexible than its RG6 peer. Installers prefer working with a more flexible cable when installing CCTVs because they often have very little room to work with.


After all this talk about older televisions, you’re probably wondering how coaxial cables changed with the technology in TVs. Well, there’s a relatively new cable that some companies are using more and more—that is, the RG11. While the design is similar to RG6 and RG59 cables, the big difference is that RG11s are better for high definition (HD) and longer runs. Back when manufacturers designed the first two coaxial cables, high definition wasn’t around, and even when HD was becoming more common, it wasn’t readily available to many. However, RG11 cables do have one advantage over the other two: consistent connection over greater distances. Both RG6 and RG59 cables begin experiencing a deteriorating connection after 100 feet, while you can usually get about an additional 100 feet out of an RG11 cable.

Coaxial cable connectors

While there are more RG series cables than the first three, the first three are by far the most common. However, there are several different connectors that you can find on coaxial cables for different applications. Of course, there are male and female plugs that go with each option, but there are six types of connectors in addition to the standard SMA:

  • BNC
  • TNC
  • SMB
  • 7/16 DIN
  • QMA
  • MCX

While there are only a few of these connectors that are regularly used, a brief explanation of each will give you a sense of the wide applications for coaxial cables. To start, the Bayonet Neil-Concelman, better known as simply BNC connector was primarily for military uses such as transferring radio and video signals. Similarly, the Threaded Neil-Concelman (TNC) is essentially the BNC only threaded since the BNC connector had a quick connect and disconnect design.

The subminiature version B (SMB) connector has a simple snap-on design and is best known for its uses in telecommunications. Similarly, the 7/16 DIN is a German design for industrial uses such as antenna systems. The QMA connector is similar to the SMA cable only it comes with a locking option. Due to the locking mechanism, QMA connectors are commonly found in industrial settings since it’s required to have a more-permanent connection. The MCX is the smallest connector of all the options available making it the best for applications that have size restrictions.

In other words, between the different types of coaxial cables and the connectors, you have plenty of options to help you get the perfect connection. However, if you’re setting up an entertainment space at home, you’re probably only going to need an RG6 with an SMA connector. If you have an old television, you might need an RG59 instead, but most applications will require an RG6. On the other hand, for a business or office building that’s setting up CCTV systems, you’ll likely need RG59 cables, so many choose to use BNC connectors. Regardless, make sure you’re getting everything you need during your order. If you’re trying to get a perfect entertainment center setup at home, assuming you have a modern television, you’re going to need an HDMI cable. Alternatively, an older television might require an RCA cable.
