1. What are wired networks?

Definition and types

Wired networks are infrastructure systems that use physical cables to transmit data, voice, and video between devices. These networks are essential in industrial environments due to their reliability and ability to handle large volumes of data. There are several types of wired networks, each with its own specific characteristics and applications:

• Structured cabling: It is a standardized cabling system that supports multiple types of hardware and is suitable for a wide range of applications. It includes twisted pair (UTP, STP) and optical fiber cables.
• Optical fiber: Uses glass or plastic filaments to transmit data through pulses of light. It is ideal for long distances and high transmission speeds.
• coaxial cables: Composed of a central conductor, an insulator, a metal mesh and an outer sheath, they are common in cable television and broadband network applications.

History and evolution

The evolution of wired networks has been driven by the need to improve communication and data transfer in industrial environments. A brief historical overview is provided below:

• Decade of 1960: Introduction of the first cabling systems for telecommunications and computer networks.
• Decade of 1980: Development of structured cabling, which allowed greater flexibility and standardization in the installation of networks.
• Decade of 1990: Advances in fiber optic technology, which offered higher speeds and transmission capacities.
• XXI century: Integration of wired networks with emerging technologies such as the Internet of Things (IoT) and industrial automation.

Main components of a cabling network

Cable networks are made up of several key elements that ensure their efficient operation:

• Cables: Cables are the physical medium through which data is transmitted. They can be twisted pair, coaxial, or fiber optic, depending on the application and network requirements.
• Connectors: Connectors are devices that connect cables to network equipment such as routers, switches, and computers. Connector types vary depending on the type of cable used.
• Patch panels: These are devices that organize and manage cable connections in a network. They facilitate the administration and maintenance of the cabling infrastructure.
• Racks and cabinets: Structures that house and protect network equipment and cables. They help maintain order and accessibility in the network installation.
• Channels and trays: Systems that guide and support cables along their route. They protect cables from damage and facilitate their installation and maintenance.

Comparison between wired and wireless networks

Although wireless networks have gained popularity in recent years, wired networks remain the preferred choice in many industrial environments due to their specific advantages:

• Reliability: Wired networks offer more stable connections that are less prone to interference, which is crucial in industrial applications where service continuity is vital.
• SpeedWired networks typically provide higher data transmission rates, which is essential for applications requiring high performance.
• SecurityWired networks are more secure, as physical access to the cables is necessary to intercept data, reducing the risk of intrusions and cyber attacks.
• Cost: Although the initial installation of a wired network may be more expensive, long-term maintenance and operation costs are typically lower compared to wireless networks.

2. Advantages of wired networks in the industry

Reliability and stability

Wired networks are known for their high reliability and stability. In industrial environments, where service continuity is crucial, wired networks offer a consistent connection that is less prone to interference. This is because physical cables are not affected by external factors such as wireless signals, weather conditions or electromagnetic interference. This reliability is essential for critical applications, such as process control and industrial automation, where any interruption can result in significant losses.

Transmission speed

One of the main advantages of wired networks is their ability to deliver high data transmission rates. Fiber optic cables, for example, can transmit data at speeds of up to 100 Gbps or more, which is significantly higher than typical wireless network speeds. This high speed is crucial in industrial environments where large volumes of data are handled, such as in system monitoring, real-time data collection, and high-definition video streaming.

Security

Security is a primary concern in any industrial environment, and wired networks offer a significant advantage in this regard. Since data is transmitted over physical cables, it is more difficult for intruders to intercept information without physical access to the infrastructure. Additionally, wired networks can be equipped with additional security measures, such as data encryption and physical access control, to further protect sensitive information. This reduces the risk of cyberattacks and ensures data integrity.

Durability and maintenance

Wired networks tend to be more durable and require less maintenance compared to wireless networks. High-quality cables, such as fiber optic cables, have a long lifespan and are resistant to harsh environmental conditions. Additionally, once installed, cables require less maintenance, reducing long-term operating costs. In industrial environments, where downtime can be costly, the durability and reliability of wired networks are significant advantages.

Loading capacity

Wired networks can handle higher volumes of data without loss of quality, which is essential in industrial applications that require consistent, high-quality data transmission. This includes sensor data transmission, machine control, and real-time process monitoring. The ability of wired networks to support heavy data loads without performance degradation ensures that industrial operations remain efficient and productive.

Practical examples of advantages in the industry

Maintenance in hostile environments

In industrial environments with extreme conditions, such as high temperatures, humidity, dust, or vibration, cables can become damaged and require frequent replacement. This can increase maintenance costs and reduce network reliability. Some examples of harsh environments include:

• Chemical factories: Cables may be exposed to corrosive substances that can damage them over time.
• Manufacturing plantsConstant vibrations from heavy machinery can affect the integrity of cables.
• Outdoor environments: Outdoor installations may expose cables to adverse weather conditions such as rain, snow, and extreme temperatures.

Physical space

Wired networks require physical space for the installation of cables and associated equipment. This can be a challenge in industrial environments where space is limited. Some aspects to consider include:

• Cable management: Cables need to be organized and managed efficiently to avoid tangles and facilitate maintenance. This may require the use of conduits, trays and racks, which take up additional space.
• Accessibility: Cables must be accessible for maintenance and repairs, which may require additional space in already congested areas.
