Internet of things is booming technology in today’s world. It is a platform where we can connect everyday things embedded with electronics, software, and sensors to the internet enabling us to collect and exchange real-time data. i.e. Internet of things is the collective platform where all of the smart devices are connected to the internet to give real-time data. This system allows greater transparency control & performance when applied to any industry or system. This can improve in the collection of data, increasing levels of automation and it allows for multiple devices to be monitored from any devices, such as phone, or laptop.

Working Principle of IoT Technology

IoT Applications addresses its key areas of networking and action through platforms, embedded systems, partner systems, and middleware. These applications are responsible for the collection of data, integration of devices, generating real-time analytics and process extension within the IoT field.

Data Collection: It uses specific protocols to aid sensors in connecting with real-time and M2M networks. After that Sensors collect data from multiple devices like smart appliances, smart wearables and many more and distribute it following IoT platform. All this data may have various levels of densities. Example: A smartphone is a device that has different sensors like GPS which is used to track real-time location.

Device Connectivity: A IoT sensors or devices can be connected to the cloud server through various communication mediums as: Bluetooth connectivity, WIFI, LoRAWAN, Cellular, satellite or connected directly to the Internet via Ethernet. Choosing which connectivity will best come down to the particular IoT Applications.

Data Processing: The massive amount of data collecting from IoT devices/sensors must be processed before the data can be used. Several things must be considered before processing of data
• Data should be transformed in a uniform format to ensure that the format must be compatible with the application.
• Stored a backup of transformed format.
• Filter unwanted data to help in improving the accuracy of data.
• Integration of additional structured data from other sources to help enhance the current data set.

Real-time Data Analysis: IoT platforms to assist analytics on data streams. IoT applications collect data from various sensors/devices and convert them into actions or clear patterns for analysis. They explore various information based on settings & designs to execute automation related tasks or provide data requisite by industry.

User Interface: The information is made available to the end-users in some way by notifying the end-user through emails, sending messages to a device such as phones or triggering alarms. However, it’s not always this informal and a one-way path. Depending upon the IoT applications and its difficulty, end-users may also be able to implement an action that may fail & affect the system. For example, a user detects some errors in the Air conditioner, the user can remotely adjust the temperature via their phone.

This is the working principle of IoT devices.

Impact of IoT upon different Industrial Sector

Internet of Things technology is one of the driving forces behind the Industrial sector. Industries like Oil & Gas, Transportation, Energy, Water, Hospitality, Agriculture and many more, embracing the IoT is helping these industries perform more effectively and efficiently.

Industrial IoT in the Transportation Sector: The transportation sector has been considered as heavily investing sector in IoT platforms. Older vehicles are being replaced by smart vehicles using IoT systems and communication technologies to generate essential information for the management of fleet operations. IoT sensors/devices used in vehicles and collects, send and receive data. After analysis of this data, truck drivers are sent real-time alerts to avoid precarious conditions and traffic jamming. IoT sensors have made cargo monitoring more secure and efficient.

Industrial IoT in the Energy Sector: IoT in energy is transforming in every part of the industry from generation to transmission to supply and changing how energy industries and consumers interact. IoT can help transform energy consumption by creating a smart grid connecting not only power stations and transmission facilities, but also control device like thermostats/sensors, energy meters, and other electric appliances to consume power optimally based on need and to supply power at off-peak times if need be to lower costs. IoT also helps maintain transmission grids by forecasting failures and detecting blockers allowing for continuous power transmission.

Industrial IoT in Oil and Gas Sector: Industries associated with the Oil and Gas are henceforward always in search of riggings and technologies that can help them to counter these complications. IoT technology is among one the technologies that with its analytics and devices abilities is permitting the Oil and Gas industries to get rid of these complications. IoT technologies allow oil and gas industries to track the performance of their oil extraction equipment from remote locations in real-time. Oil and Gas pipeline monitoring is the best benefit of the Oil and Gas sector. IoT technology is used for the measurement of the level monitoring of the Oil and Gas tanks.

Industrial IoT in the Water Sector: IoT technology used in water sectors to monitor real-time water consumption and level of the water tanks. IoT enabled smart water meters to monitor temperature, pressure & quality of water (PH, Turbidity, Temperature, Dissolved Oxygen, TDS, Salinity, etc.). IoT smart water meters are used to get real-time monitoring of the pipeline, smart water meter sends the alerts about the leakage & temperature and prevents water pipeline from the bursting. IoT technology gives complete control by synchronizing the system with mobile devices through mobile and web app for simple and precise controlling of water consumption.

Conclusion: There are several innovations that are done because of IoT technology. IoT technology is revolutionizing the world by making the world smarter in every aspect, either in homes or industrial sectors. However, It is important for every sector or industry i.e big or small needs to configure IoT technology to develop their business. IoT technology also helps to hold huge potential for everyone how to better engage and satisfy their consumer.

Optical splitter is one of the important passive devices in optical fiber link. It is mainly to implement the optical signal splitting between the optical line terminal OLT and the optical network terminal ONU in the passive optical network.

The optical splitter enables the signal on the optical fiber to be distributed between two or more optical fibers with different separation configurations, such as 1×2, 1×4, 1×N, or 2×4, M×N. The general architecture of FTTH is: OLT (Machine room office end) — ODN (Passive optical network distribution system) — ONU (User end). An optical splitter is used in ODN to realize that multiple end users share a PON interface. In the PON network, when buildings are scattered and irregular, such as villas, with long distances and low user density, the centralized light splitting method can make full use of resources and cover the surroundings.

In a passive optical network, only one optical splitter can be used, or multiple optical splitters can be used together to separate optical signals.

The performance indicators that affect the optical splitter are usually as follows:

Insertion lossThe insertion loss of a fiber splitter refers to the dB of each output relative to the input optical loss. Generally, the smaller the insertion loss value, the better the performance of the splitter.

Splitting ratioThe split ratio is defined as the output power of the splitter output port in the system application. Generally, the splitting ratio of the PLC splitter is uniformly distributed, while the splitting ratio of Fused optical splitter can be unequal. The splitting ratio is related to the wavelength of the transmitted light. For example, when transmitting 1.31μm light, the splitting ratio of the two output light ends is 50:50; when transmitting 1.5 μm light, it becomes 70:30 (This happens because that optical splitter has a certain bandwidth, which is the bandwidth of the optical signal transmitted when the splitting ratio is substantially unchanged).

IsolationIsolation refers to a light path optical splitter to other optical path of the optical signal isolation.

Return lossReturn loss, also known as reflection loss, refers to the power loss of an optical signal that is returned or reflected due to discontinuities in the fiber or transmission line. The larger the return loss, the better, to reduce the impact of reflected light on the light source and the system.

In addition, uniformity, directivity, and PDL polarization loss are also parameters that affect the performance of the beam splitter. Optical fiber splitter is one of the most important passive devices in the optical fiber link. It is particularly suitable for connecting MDF and terminal equipment to distribute optical signals in passive optical networks (EPON, GPON, BPON, FTTX, FTTH, etc.). .
