Optical Fibres in Communication
An optical fiber is a glass or plastic fiber that carries light along its length. They are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communications. Fibers are used instead of metal wires because signals travel along them with less loss, and also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles to carry images. Specially designed fibers are used for other applications, including sensors and fiber lasers.
Fibre optics
The document discusses the history and components of fiber optics. It explains that fiber optics use thin glass strands called optical fibers to transmit light signals over long distances. The core of the fiber carries the light signals, while the cladding reflects them down the core. There are two main types of fibers: single-mode fibers which carry light in a single path, and multimode fibers which use graded or step indexes to carry light along multiple paths. Fiber optics are replacing copper wire for data transmission due to advantages like higher speeds, larger bandwidth, longer transmission distances, and lower maintenance costs.

Macro Bending Losses in Single Mode Step Index Fiber
Macro Bending Losses in Single Mode Step Index FiberInternational journal of scientific and technical research in engineering (IJSTRE)
Bending losses of power in a single mode step index optical fiber due to macro bending has been
investigated for a wavelength of 1550nm. The effects of bending radius (4-15mm, with steps of 1mm), and
wrapping turn (up to 40 turns) on loss have been studied. Twisting the optical fiber and its influence on power
loss also has been investigated. Variations of macro bending loss with these two parameters have been
measured, loss with number of turns and radius of curvature have been measured.
This work founds that the Macro bending and wrapping turn loss increases as the bending radius and wrapping
turn increases.OPTICAL_FIBER.pptx

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

- 4. 4 INTRODUCTION Optical Fibers are hair-thin, transparent strands through which light can be transmitted. A group of many such optical fibers constitute a Optical Fiber Cable.
- 5. 5 CONSTRUCTION The main parts of an optical fiber are : Core – thin glass center of the fiber where light travels. Cladding – outer optical material surrounding the core. Buffer Coating – plastic coating that protects the fiber. Other protective coatings.
- 6. 6 PRINCIPLE TOTAL INTERNAL REFLECTION is the main principle behind the working of an optical fiber. For T.I.R., conditions are satisfied : • Light is incident on the walls of the cable at an angle greater than the critical angle. • The optical-fiber core is clad (coated) by a lower density glass layer.
- 7. 7 FIBER TYPES 1. Plastic core and Plastic cladding 2. Glass core with Plastic cladding PCS (Plastic-Clad Silicon) 3. Glass core and Glass cladding SCS (Silica-clad silicon) 4. Under research: Zinc-chloride (non-Silicate) 1000 time as efficient as glass ON THE BASIS OF MATERIAL :
- 8. 8 ON THE BASIS OF MODE OF PROPAGATION : 1. Singlemode Fiber : Only one path for the propagation of light. The core is made very small (about 7-10 µm). 2. Multimode Fiber : More than one paths for the propagation of light. Core is larger in diameter (about 20-100 µm).
- 9. 9 ON THE BASIS OF INDEX PROFILE 1. Step-Index Fiber : Refractive index of the core as well as the cladding is uniform. Light rays propagate in the form of meridional rays, i.e. they follow a zigzag path and, for every reflection they will cross the fiber axis. 2. Graded Index Fiber (GRIN Fiber): Refractive index of the core is not uniform, while that of the cladding is uniform. Light rays propagate in the form of skew rays, i.e. they follow a helical path and will never cross the fiber axis.

- 13. 13 ADVANTAGES OF OPTICAL FIBER Capacity: much wider bandwidth (10 GHz) Crosstalk immunity Immunity to static interference Lightning Electric fields Florescent light Higher environment immunity Weather, temperature, etc. Safety: Fiber is non-metallic. No explosion, no shock Lasts longer. Security: tapping is difficult Economics: Fewer repeaters Low transmission loss (dB/km) Fewer repeaters Less cable Remember: Fiber is non-conductive Hence, change of magnetic field has No impact!
- 14. 14 DISADVANTAGES OF OPTICAL FIBER Higher initial cost in installation Interfacing cost Less strength Lower tensile strength Remote electric power More expensive to repair/maintain Tools: Specialized and sophisticated
- 15. 15 APPLICATIONS In Telecommunications to transfer data. In Local Area Networks to share internet connections. In Cable TV and CCTV. In Optical Fiber Sensors. In Endoscopy to view internal body organs. In decoration.
