[Solved] Clicking on Tailscale icon does not let me login

Occasionally i have come accross a Tailscale client that does not initially want to display the log in page.

I originally also tried running CLI commands like “tailscale up –authkey xxxxxxxxxx” as well – it seems to hang.

tailscale login icon in taskbar

So when CLI and clicking on the icon in the taskbar via the GUI to log in doesn’t work – Check your network cards!
This is usually caused when Tailscale cannot tell which network card has priority.

On Windows:

Win + R //to open run
ncpa.cpl //to open the network settings
Select main network card
Open Properties, then IPv4
Click on Advanced, untick ‘Automatic Metric
Set to 10.

Try again. Chances are, tailscale will now let you login and generate the login page popup allowing sign on. Authkey authentication should also now work.

Fibre Multiplexing: An Overview of Frequency Division Multiplexing (FDM)

Fibre Multiplexing: An Overview of Frequency Division Multiplexing (FDM)

Fibre multiplexing is a technique used to transmit multiple signals over a single fibre optic cable, allowing for efficient use of bandwidth and high transmission rates. One popular method of fibre multiplexing is frequency division multiplexing (FDM).

In this article, we’ll take a closer look at FDM and its key features, advantages, and disadvantages.

What is Frequency Division Multiplexing (FDM)?

Frequency division multiplexing (FDM) is a method of transmitting multiple signals over a single fibre optic cable by using different frequency bands for each signal. This allows for a higher capacity and faster transmission rates, as multiple signals can be transmitted simultaneously over the same fibre optic cable.

FDM is commonly used in telecommunications and other applications where a large amount of data needs to be transmitted over long distances. It is also used in local area networks (LANs) and other short-distance applications.

Advantages of FDM

There are several advantages to using FDM as a method of fibre multiplexing:

  • High capacity: FDM allows for a higher capacity than other methods of fibre multiplexing, as multiple signals can be transmitted simultaneously over the same fibre optic cable.
  • Fast transmission rates: FDM allows for fast transmission rates, making it suitable for high-speed data transmission over long distances.
  • Efficient use of bandwidth: FDM allows for efficient use of bandwidth, as multiple signals can be transmitted simultaneously over the same fibre optic cable.

Disadvantages of FDM

There are also some disadvantages to using FDM as a method of fibre multiplexing:

  • Complexity: FDM systems can be more complex to set up and manage than other methods of fibre multiplexing.
  • Interference: FDM systems are susceptible to interference from other signals in the same frequency band, which can degrade the quality of the transmitted signal.

Overall, FDM is a useful method of fibre multiplexing that can provide high capacity, fast transmission rates, and efficient use of bandwidth in certain situations. However, it’s important to carefully consider the potential complexity and interference issues of FDM systems when deciding which method of fibre multiplexing is right for you.

Fibre Multiplexing: An Overview of Time Division Multiplexing (TDM)

Fibre Multiplexing: An Overview of Time Division Multiplexing (TDM)

Fibre multiplexing is a technique used to transmit multiple signals over a single fibre optic cable, allowing for efficient use of bandwidth and high transmission rates. There are several different methods of fibre multiplexing, including time division multiplexing (TDM).

In this article, we’ll take a closer look at TDM and its key features and benefits.

What is Time Division Multiplexing (TDM)?

Time division multiplexing (TDM) is a method of transmitting multiple signals over a single fibre optic cable by assigning each signal to a specific time slot. This allows for efficient use of bandwidth, as the cable is used effectively and there is less risk of congestion.

However, TDM also has some limitations. One major limitation is that the transmission rate of each signal is limited by the time slot assigned to it. This means that if a signal requires a larger time slot, it may not be able to be transmitted at the same rate as other signals.

Overall, TDM is a useful method of fibre multiplexing that can provide efficient use of bandwidth and high transmission rates in certain situations. It’s important to carefully consider your specific needs and requirements when deciding which method of fibre multiplexing is right for you.

Fibre: Selecting Between Multimode and Singlemode Cables

Fibre: Selecting Between Multimode and Singlemode Cables

When it comes to transmitting data over long distances, fibre optic cables are an increasingly popular choice because they are able to provide fast, flexible connectivity. These cables have a core that serves as a “light guide,” allowing light (or data) to be transmitted from one end of the cable to the other.

There are two main types of fibre optic cables: singlemode and multimode. Understanding the differences between these two types of cables can help you choose the right one for your specific needs.

Multimode Cables

Multimode cables are designed to transmit multiple modes of light at the same time. These cables have a larger core diameter, usually between 50 and 100 µm, and are designed for shorter distances. They are often used in local area networks (LANs) and other short-distance applications.

Here are three common use cases for multimode cables:

  1. LANs: Multimode cables are often used in local area networks (LANs) because they are able to transmit data over short distances at high speeds.
  2. Campus environments: Multimode cables are well-suited for use in campus environments, where data needs to be transmitted between buildings or within a single building.
  3. Short distance telecommunications: If you need to transmit data over a short distance, such as between two rooms in a building, multimode cables may be a good choice.

Singlemode Cables

Singlemode cables are designed to transmit a single mode of light at a time. These cables have a small core diameter, usually between 8.3 and 10.5 µm, and are designed for long distances. They can transmit data at high speeds, making them a popular choice for telecommunications over long distances.

Here are three common use cases for
singlemode cables:

  1. Long distance telecommunications: If you need to transmit data over a long distance, such as between a local phone exchange and an end user, singlemode cables are the better choice. These cables can transmit data at high speeds over long distances and are designed specifically for this purpose.
  2. High-speed data transmission: If you need to transmit data at high speeds, singlemode cables are the better choice. These cables are designed for high-speed data transmission and are capable of transmitting data at high rates over long distances.
  3. WANs: Wide area networks (WANs) often require the transmission of data over long distances. Singlemode cables are well-suited for this purpose because they are able to transmit data at high speeds over long distances.

Conclusion

When choosing between singlemode and multimode cables, it’s important to consider the distance you need to transmit data, the data rate you require, and the wavelength of light that is being used. By understanding these differences, you can choose the right type of fibre optic cable for your specific needs.

In general, singlemode cables are the better choice for long distance telecommunications, while multimode cables are better suited for short distance applications such as local area networks (LANs). Ultimately, the right choice for you will depend on your specific needs and requirements.

They can transmit data at high speeds, making them a popular choice for telecommunications over long distances.

Multimode cables, on the other hand, are designed to transmit multiple modes of light at the same time. These cables have a larger core diameter, usually between 50 and 100 µm, and are designed for shorter distances. They are often used in local area networks (LANs) and other short-distance applications.

Fibre: What Makes Up a Fibre Cable?

Fibre: What Makes Up a Fibre Cable?

Fibre optic cables are special cables that are used to transmit data using pulses of light. They are made up of several different components, each of which plays a specific role in the transmission of the light signals. Here is a breakdown of the main components of a fibre optic cable:

  • Glass fibre: The glass fibre is the tiny strand of glass that transmits the light signals. It is extremely thin, often less than a tenth the diameter of a human hair. The glass fibre is protected by a layer of plastic called the cladding, which helps to keep the light signals confined to the centre of the fibre. The glass fibre and cladding are encased in a protective jacket, which helps to protect the fibre from damage.
  • Buffer coating: The buffer coating is a layer of protective material that surrounds the glass fibre and cladding. It helps to protect the fibre from damage and also makes it easier to handle.
  • Strength members: Strength members are added to the fibre optic cable to provide additional support and protection. They may be made of materials such as Kevlar or steel and are used to help the cable withstand the forces that it may encounter during installation and use.
  • Outer jacket: The outer jacket is the outermost layer of the fibre optic cable. It serves as an additional layer of protection for the cable and helps to prevent moisture, dirt, and other contaminants from entering the cable. The outer jacket also helps to protect the cable from physical damage.

By understanding the different components of a fibre optic cable, you can better understand how these cables work and how to properly install and maintain them.

Fibre: What Makes Up a Fibre Connector?

Fibre: What Makes Up a Fibre Connector?

Fibre optic connectors are special connectors that are used to join two fibre optic cables together or to connect a fibre optic cable to a device. These connectors are different from other types of connectors because they transmit pulses of light instead of electrical signals. This means that the connectors must be very precise in order to align the tiny glass fibres that transmit the light signals perfectly.

There are many different types of fibre connectors, but they all have some similar parts. One important thing to consider when choosing a fibre connector is whether it is simplex or duplex. Simplex connectors have only one connector on each end, while duplex connectors have two connectors on each end.

There are four main parts to a fibre connector: the glass fibre, the ferrule, the connector body, and the coupling mechanism.

  • The glass fibre is the tiny strand of glass that transmits the light signals. It is extremely thin, often less than a tenth the diameter of a human hair. The glass fibre is protected by a layer of plastic called the cladding, which helps to keep the light signals confined to the centre of the fibre. The glass fibre and cladding are encased in a protective jacket, which helps to protect the fibre from damage.
  • The ferrule is a thin, cylinder-shaped part that holds the glass fibre. It has a hollow center that grips the fibre tightly. Ferrules are usually made of ceramic, metal, or strong plastic, and they usually hold just one strand of fibre.
  • The connector body is a plastic or metal part that holds the ferrule and connects to the fibre cable jacket to strengthen it.
  • The coupling mechanism is a part of the connector body that holds the connector in place when it is connected to another device (like a switch or a router). It could be a latch clip, a bayonet-style nut, or something similar.
