USB Cable Plug

USB cables are mainly used for transferring data and charging devices. This seems to be a simple statement. Many buyers purchase cables directly thinking they’re all the same and created equal. This is not entirely true. When you purchase the wrong cables, several problems may occur, like the USB ports stop working, no sound coming out from your home entertainment system, an error prompt saying the device cannot be found, and your device not charging.

This article will give you the whole concept of USB cables – what it is, how it’s made, why you need them, and how to purchase the right one. If you’ll read throughout the article, you’ll be able to buy the proper USB cable in a single try!

 

Chapter I: The Fundamentals of USB

1.1 What Is USB (and what does it do)?

The USB, or Universal Serial Bus, is an industry-standard developed so computer components, such as keyboards, mice, printers, digital cameras, network adapters, disk drives, etc., can connect to personal computers. Today the USB feature is present in other devices, like gaming consoles and smartphones.

 

1.2 How Does USB Work?

By plugging a USB cable into the USB port of a computer, a connection is made between the electronic device and the computer. Through this connection, short-distance data transfer can be done. The computer can also supply electric power to the device it’s connected with.

 

1.3 What Are the Features of USB?

The USB interface went through a lot of updates due to the advancement of technology. So far, these are the features that come with USB:

 

1.4 The USB Standards

USB was developed to keep up with technology. With many modernized devices, the performance of the USB also has to be updated and improved. As a result, there are four USB standards. These are:

This was the first version of USB. It was released in September 1998 and provided a master-follower interface, wherein the “master” is the computer and the “followers” are the devices connected to it. The USB can support up to 127 devices and 6 hubs or tiers.

The goal of this standard was to simplify the complication within the device by letting the host (computer) do the processing.

The data transfer speed of this standard is 1.5Mb/s for low speed and 12Mb/s for full speed. The length is only up to five meters. Due to power limitations, it doesn’t allow the use of pass-through monitors and extension cables.

This standard is an improved version of the USB 1.1. It was released in April 2000. The main difference is the transfer speed was upgraded to “high-speed,” which is capable of up to 480Mb/s. However, even though devices are marked USB 2.0, it doesn’t mean all of them can meet the full speed.

Another standard that was initially launched in September 2007; the highlight of this standard is the SuperSpeed feature. It has a fourth transfer mode, which provides a transfer rate of 4.8Gbit/s.

The USB 3.0 is backwards compatible with USB 2.0. Usually, the USB ports on computers and other similar devices will have the label “SS”, which means SuperSpeed or USB 3.0.

The latest and most advanced USB standard. It was launched in July 2013 and can transfer up to 10Gb/s of data.

 

Chapter II: What You Need to Know About USB Cables

We know how a USB cable looks like and basically what it does. But, do we really know all of its capabilities? Let’s go over the facts that we should know about USB cables:

 

2.1 What Are USB Cables?

Fiber Optic USB 3.0 Cable are used mainly to connect computers to peripheral devices, such as printers, scanners, cameras, and more. They come with the following advantages:

 

 

2.2 What Is a USB Cable Made Of?

USB cables are made up of two main parts: the cable itself and the connector. The cable comes with a few basic parts. They have two connecting ends, the wires found inside, and the sheath that surrounds the wires. The wires are usually made from silver and copper since both metals are excellent conductors. Usually, they come with a ferrite bead to minimize high-frequency noise.

The connectors are usually made from brass, but newer versions are now gold-plated. The “A” connector will be plugged into the computer, while the “B” goes to the peripheral device.

 

2.3 The Different Types of USB Connectors

Chapter III: Is USB-C the Emerging USB Version? (Should you get one?)

As the latest connector type to be released, the USB-C has a lot to offer. It is smaller, fast, and reversible. Gone are the days when you can’t plug it on your first try! Due to its advanced features, even newer models of Apple products now come with USB-C ports.

The USB-C is not a new standard. It’s not the same as the USB 1.1, 2.0, 3.0, and 3.1. USB standards focus on the capacity of the connection, while the USB-C focuses on the physical connection, similar to the mini-USB and micro-USB.

The goal of this connector is to replace all USB types of both the host and peripheral devices. It is even small enough not to accommodate the mini and micro USBs. It also runs the USB 3.1 standard, allowing it more power and a faster speed rate.

Since the recent models of devices come with the USB-C ports, it will be useful to have one. It’s highly likely that your smartphone comes with the USB-C port. Since this connector type is not used in all devices yet and is not physically compatible with the previous standards, you can get the USB-C to USB-A cables.

 

Chapter IV: What is USB-OTG? (Is it worth it?)

OTG cable

USB On-the-Go or USB-OTG is a standard used in many Android smartphones that lets them function as USB hosts by reading data directly from USB devices.

For example, you have a laptop, a smartphone, and an external hard drive. To move the files from the external hard drive to the smartphone, you’ll have to transfer the files to the laptop first. Then, connect your smartphone to the laptop to start transferring the files.

By using the USB-OTG, you will no longer need the laptop and you can transfer the files from the external hard drive to your phone directly.

Another example is you can use game controllers through the USB-OTG when playing certain games on your smartphone. However, they don’t work on games that were designed to be played through touchscreens, like The Clash of Clans. They do work on more classic games like Sonic 2 from Sega.

Is it worth getting? It really depends on you. If you use your phone a lot for different functions, like saving and transferring files, playing games, or even use it with your DSLR to transfer images faster, then the USB-OTG can be useful.

 

Chapter V: Tips on Buying the Right USB Cable

Even though you can easily find sellers and distributors, it would still be a hassle to go back and forth since your USB cables are not working. It’s going to be a waste of your time and money. So, before you buy your next USB cable, take the following into consideration:

 

With that in mind, it’s time that you think about the features you want for your USB cable:

What Is a Good USB Cable?

While USB cables look similar on the outside, they might be different on the inside. For USB charging cables, some charge at a slow rate while others don’t charge at all. These are common problems consumers deal with when they directly buy USB cables without considering what makes a good one.

When you’re looking for a USB cable to charge your gadgets, like smartphones, tablets, and cameras, you must look for the following features:

 

Chapter VI: How Is a USB Cable Manufactured?

USB Cable Ways

If you are an electronic brand owner, you are going to need a professional cable manufacturer. There are thousands of cable manufacturers who can produce your customized USB cables. Getting to know how it’s made is going to help you find the perfect cable suppliers.

Before we go through the manufacturing process, let’s understand first what goes on inside a USB cable. It has four wires inside – usually, they’re black, white, green and red. In most electronic devices, the black wire is the ground wire, the white wire is a positive wire and indicates data, the green wire also indicates data, but is a negative wire, while the red one indicates positive wire with five volts of DC power.

However, some USB cords use different color combinations for the wires, like green, blue, orange, and white. If this is the case, the green wire indicates positive data, the blue is negative data, the orange is the positive wire with five volts of DC power, and the white one indicates the ground wire.

So, how are USB cables made?

Step 1: Cable Cutting

Often, the raw cable is long, so they have to be cut into the appropriate lengths, like one meter, three meters, six meters, and so on.

Step 2: Opening the Inner Conductor

As previously discussed, the USB cable is made up of four different wires, which can be found inside. Aside from the wires, braid and foil can be found to avoid electromagnetic interference. In this step, the inner conductor must be displayed so they can be connected to the connector. This step will involve the following:

Step 3: Linking the Terminal and the Wire

In most cases, tin is used to solder electronic products. This is because it has useful features, like low melting point, good affinity to copper and iron surface, and excellent fluidity once melted. This step will require the following tasks:

Step 4: Molding

This step will involve covering back the joint of the connector and cable by using an injection molding machine. This step will include the following:

 

Step 5: Final Inspection and Packaging

The final step will involve inspecting the appearance of the cables and checking again to make sure there are no defects. Defective products will then be cleared out, then the rest will be packed according to the requests of customers.

 

Conclusion

Even though USB cables look almost identical physically, they are actually different in many ways – transfer speed, connector types, functions, size, and other features. This is why it’s important that you determine first what functions you want for your USB cables to avoid problems when purchasing.
