An optical fiber is proposed with a segmented core and depressed cladding regions to reduce nonlinearity and bend loss. The segmented core decreases optical and acoustic coupling to increase the stimulated Brillouin scattering (SBS) threshold. Depressed cladding regions improve bend properties. Test results show the fiber has an SBS threshold over 12 dBm and bend losses under IEC standards, enabling its use in a single fiber for both feeder and customer segments of fiber-to-the-home networks. This simplifies deployment and reduces costs compared to using multiple fiber types.

AEN089.pdf
1. Optical fiber termination methods like no-epoxy-no-polish connectors, epoxy and polish connectors, and pigtail splicing impact the insertion loss and return loss of telecommunications systems. The precision of polishing and minimizing the air gap at connector interfaces is important for low loss.
2. Factory-controlled termination processes provide more consistent optical performance than field installations. No-epoxy-no-polish connectors and pigtails have insertion loss and reflectance measured during manufacturing.
3. Field installers must measure insertion loss but typically do not measure reflectance, which is impractical. The proper termination method should be chosen to meet loss budget and industry standard specifications.
IRJET- Reduction of Dispersion using FBG in Fiber Optic Communication
This document discusses reducing dispersion in fiber optic communication systems using fiber Bragg gratings (FBG).

This document describes a cable fault detection system (CFD) that uses digital communication over optical fibers to detect faults in cables without requiring a direct current power supply. It consists of a master device with a power supply and slave devices located at cable heads without power. Slave devices generate their own power from fault currents or normal cable power flows. They digitize electrical measurements, transmit the data optically to the master, which identifies faults by comparing slave and master measurements. The system was tested on a 66kV substation cable system, detecting 11 external faults correctly without operating elements for internal faults. It confirms the slave devices can self-power and the master can synchronize sampling to accurately locate faults.

The core idea of this project to minimize the paper work and centralize the

application the information will be stored in client itself. For further security the
data base is stored in the back-end oracle and so no intruders can access it.
A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

Presentation on Food Delivery Systems
This presentation is about Food Delivery Systems and how they are developed using the Software Development Life Cycle (SDLC) and other methods. It explains the steps involved in creating a food delivery app, from planning and designing to testing and launching. The slide also covers different tools and technologies used to make these systems work efficiently.
Accident detection system project report.pdf
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.
