Where Do IT Services Come From?

What is an IT service desk?

The IT service center is intended to be a main point of participation between users and an IT organization. According to ITIL, the service center is the only point of contact (SPOC) between the service provider (IT) and the users for daily activities. A typical service center handles incidents (interruptions) and support requests (regular service activities) as well as managing user communications for things like interruptions and planned service changes. A service center is usually large in size and is designed to provide the user with a single location for all of their IT needs. This leads the service desk to play a key role in facilitating the integration of business processes with the technological ecosystem and a broader service management infrastructure.

Where do IT services come from?

The role of the IT support service was born in the late 1980s as a support capacity for solving IT problems. It was a highly technical feature focused on technology rather than end users. Early computer helpdesks did not have the concept of SLA or time targets for problem solving. It wasn't until ITIL entered the scene in the 1990s, capturing IT service best practices, that the user-centric concept of the IT service table began to emerge. The service center was seen as an essential part of "IT management as a service".

In the mid-1990s, a study by Iain Middleton of Robert Gordon University found that value came not only from a responsive response to user problems, but also from the help desk's unique position for communicating daily with many customers or employees. Information obtained about technical issues, user preferences, and what satisfies users can be useful in planning and developing IT services.

With the release of ITIL v2 in 2001, the Service Desk function and its role in handling incidents and requests has become an important component of IT service operations in many organizations. Over the decade, globalization combined with increasing pressures to reduce IT operating costs have led many organizations to centralize the functions of the IT service center with many external support partners who have hired them. The outsourcing of IT service center functions has led to greater standardization of processes and the growth of the support ticket software market.

Modern technological trends, including cloud services, the widespread use of third-party components in the IT ecosystem and advances in detection and monitoring capabilities have led to the integration of independent support service ticket systems into more complete ITSM platforms that act as an operations center not only for the IT helpdesk, but for the entire IT function. As businesses seek to modernize and move forward with digital transformation initiatives, the IT services office is evolving again to focus more on the business, with greater awareness of business processes and data , becoming in many cases an integral part. business operations of companies.

How Fiber Optic Works? Types of Fiber Optic Cables

Fiber optic refers to the medium and technology associated with the transmission of information, such as pulses of light along a cable or fiberglass or plastic. Fiber optic is used for high performance and long distance data networks.

Optical fibers are also commonly used in telecommunications services such as the Internet, television and telephones. For example, companies such as Verizon and Google use optical fibers in their Verizon FIOS and Google Fiber services, offering users gigabit Internet speeds.

Fiber optic cables are used because they have numerous advantages over copper cables, such as greater bandwidth and transmission speed.

A fiber optic cable can contain a variable number of these glass fibers, from a few to two hundred. Around the fiberglass core is another layer of glass called a coating. A layer known as a protection tube protects the coating and a coating layer serves as the final protective layer for the individual cable.

How fiber optic works

Optical fibers transmit data in the form of light particles, or photons, that pulse through a fiber optic cable. The fiberglass core and the coating have a different index of refraction that doubles the incoming light at a certain angle. When light signals are sent through the fiber optic cable, they are reflected in the core and cladding in a series of zigzag rebounds, adhering to a process called total internal reflection. The light signals do not travel at the speed of light due to the denser layers of glass, but travel approximately 30% slower than the speed of light. To renew or improve the signal during your trip, fiber optic transmission sometimes requires repeaters at distant intervals to regenerate the optical signal by converting it into an electrical signal, processing that electrical signal and retransmitting the optical signal.

Fiber optic cables move to support signals up to 10 Gbps. Usually, as the bandwidth capacity of a fiber optic cable increases, it becomes more expensive.

Types of fiber optic cables

Multimode and singlemode fiber are the two main types of fiber optic cable. Singlemode fiber is used for longer distances due to the smaller diameter of the fiberglass core, which reduces the possibility of attenuation: the reduction of the signal strength. The smaller aperture isolates the light into a single beam, which offers a more direct path and allows the signal to travel a greater distance. Singlemode fiber also has significantly more bandwidth than multimode fiber. The light source used for singlemode fiber is typically a laser. Singlemode fiber is generally more expensive as it requires precise calculations to produce laser light with a smaller aperture.

Multimode fiber is used for shorter distances because the larger central opening allows light signals to bounce and reflect more along the way. The larger diameter allows multiple light pulses to be sent simultaneously through the cable, ensuring greater data transmission. However, this also means that there is a greater possibility of signal loss, reduction or interference. Multimode optical fibers generally use an LED to create the light pulse.

While copper wire cables have been the traditional option for telecommunications, networks and cable connections for years, fiber optics have become a common alternative. Most of the long distance telephone lines of the telephone companies are now made with fiber optic cables. Optical fiber carries more information than conventional copper cable due to its higher bandwidth and higher speeds. Since glass does not conduct electricity, the optical fiber is not subject to electromagnetic interference and signal losses are minimized.

Advantages and disadvantages

Fiber optic cables are mainly used for their advantages over copper cables. Benefits include:

• Support for more bandwidth capabilities.
• Light can travel further without the need to increase the signal.
• They are less sensitive to interference, such as electromagnetic interference.
• They can be immersed in water-based optical fibers that are used in more dangerous environments, such as underwater cables.
• Fiber optic cables are also stronger, thinner and lighter than copper cables.
• They should not be repaired or replaced as often.

However, it is important to keep in mind that optical fibers have disadvantages that users must take into account before administering them. These disadvantages include:

• Copper wire is often cheaper than fiber optics.
• Fiberglass also requires more protection within an external cable than copper.
• Installing new cables requires a lot of labor.
• Fiber optic cables are often more fragile. For example, the fibers may break or a signal may be lost if the cable bends or curves within a radius of a few centimeters.

What is Fiber Optic Splicing ?

Fibrlok mechanical splice kit Knowledge of fiber optic splice methods is vital for any fiber optic company or technician involved in telecommunications or LAN and network projects.

In a nutshell, the fiber optic joint involves the joining of two fiber optic cables. The other most common method of joining fibers is called termination or connectorization. Fiber splice typically results in less loss of light and back reflection than termination, making it the preferred method when cables are too long for a single length of fiber or when two different types of cables are joined, such as a fiber 48 with four 12- fiber cables. The splice is also used to restore fiber optic cables when an underground cable is accidentally cut.

There are two methods of fiber optic splice, fusion splice and mechanical splice. If you are just starting to connect fiber, you can examine your long-term goals in this field to choose which technique best suits your economic and performance goals.

Fibrlok Mechanical Splice - Mechanical Splicing:

Mechanical couplings are simply alignment devices, designed for

keep both ends of the fiber in a precisely aligned position, allowing light to pass from one fiber to another.

 Fusion Splicing:

In the fusion union, a machine is used to precisely align the two ends of the fiber; then the ends of the glass are "melted" or "welded" together, using a kind of heat or electric arc. This produces a continuous connection between the fibers, allowing for very low light transmission loss. (Typical loss: 0.1 dB)

Which method is better?

The typical reason for choosing one method over the other is the economy. The mechanical joint has a low initial investment ($ 1,000 - $ 2,000), but costs more per joint ($ 12 to $ 40 each). Although the cost per modification for the fusion splice is lower ($ 0.50 - $ 1.50 each), the initial investment is much higher ($ 15,000 - $ 50,000, depending on the accuracy and resources of the weld by purchased merger). The more precise the alignment (the better the alignment in less losses), the more you pay for the machine.

As for the performance of each joining method, the decision is generally based on the sector in which you are working. The casting joint produces fewer leaks and less reflections in the back than the mechanical joint, since the junction points resulting from the casting are almost continuous. Fusion splices are mainly used with singlemode fiber, while mechanical splices work with singlemode and multimode fiber.

Many telecommunications and CATV companies invest in fusion splices for their long-haul networks in a unique way, but will still use mechanical splices for shorter local cable lines. Since analog video signals require minimal reflection for optimal performance, the fusion junction is also preferable for this application. The LAN industry can choose one of the methods, as signal loss and reflection are minor problems for most LAN applications.

Fiber Splicer: Salary

The average fiber splicing technician salary in the United States is $ 195,000 per year or $ 100 per hour. Starting positions start at $ 35,100 a year, while more experienced workers earn up to $ 195,000 a year.
