The Benefits And Demerits Of FTTH Cable

 

One medium that is becoming increasingly popular for transmitting data is Fiber Optics. One feature that stands it out amongst its users is its speed of data transmission. This is a huge rise when compared with conventional methods. FTTH is an acronym for Fibre to the Home. Many experts believe that the use of traditional copper cables will soon become a thing of the past, as they will be replaced by FTTH cables. There are many other components of FTTH. Another name for FTTH drop cable is Indoor cable. Instrumentation cables and Cable glands are other elements of the technology. The capacity to deliver high speed broadband to households is a factor that is endearing more people to households. It combines voice, video, and data. Here are some of the benefits and demerits of this upcoming technology; .

BENEFITS



1) Internet Speed:

One of the biggest advantages of FTTH is the improved internet speed. Internet is continuously becoming the pillar of communication around the world. Internet speed is the chief factor, whether people want to stream videos, have video chats or download songs. By improving internet speed, FTTH is making it possible for people to stay in touch. It is especially pertinent at this time when more people work from home, and therefore need faster internet to ensure that they are connected all the time.

2) Technology:


Fiber Optic has a more defined and advanced technology compared to traditional copper which uses analog lines that generate signals through the connected telephone device.

3) Upcoming Applications:

 

Households that have the FTTH are sure to stay connected with the latest technology, as various new applications come up regularly.

 

4) Vendors:

 

HA major advantage of having this all new technology is the ease of getting vendors for Fiber to the Home.

DEMERITS

The cost of getting the cable and having it installed is the only disadvantage of having FTTH cable. For many households, the FTTH cable is out of their reach simply because they cannot afford it.
Nevertheless, the Fiber to the Premises (FTTP) is another concept which brings Fiber to a specific location.
The Fiber to the Premises is less expensive to install than the Fiber to the Home.

In a nutshell, FTTH cable is changing the way we communicated in the past, and it will soon become the standard.

The web develops daily and rapidly, just like any other technology. There’s some kind of confusion concerning its evolution and versions. However, the most acceptable stages of evolution are;


-Web 1.0
-Web 2.0
-Web 3.0 (also known as Semantic Web)

 

Difference Between The 3 Versions


Web 1.0: The Read-Only era; this was the internet before 1999. During this period, the internet user was only able read information. The most apt examples of these are millions of static websites which sprang up during the .com boom.
Communication and information flow was inactive between the producer of the information and the consumer of the information.


Web 2.0:

 

The birth of Web 2.0 occurred as a result of the absence of active interaction of common user with the web.
The year 1999 signaled the start of the Read-Write-Publish era with significant contributions from LiveJournal which was launched in April, 1999, while blogger was launched in August of the same year.
These days, even a non tech savvy person can interact and actively contribute to the web by exploring different blog platforms.
This period empowered the common user with a couple of new concepts through Blog, Social Media and Video Streaming. A few clicks and your content is published!
A few notable developments of Web 2.0 are YouTube, Twitter, Facebook, eZine Articles and Flickr.


Web 3.0:


In spite of the exciting developments in Web 2.0, and how it seemed like the solution to all the problems we could ever encounter, it lagged behind when it came to intelligence.
Its analytical abilities were poor. One couldn’t carry out keyword based searches without reaping information overload.

The Web 3.0 will possess the following characteristics;

Tailor-made Search:
provides answers required for a specific search. It is perfectly suited to a particular search.
Contextual Search:
increases the precision of web-based results based on their importance to   specific users
Personalized Search:
here, search engine results are customized to suit an individual’s interest by “going beyond the call of duty” to provide information beyond what is asked.
Deductive Reasoning:
is the process of reasoning from different angles in order to reach a logical conclusion.
Evolution of 3D Web:
the interplay of web technologies, and how they continue to develop over time

Even though the Web is yet to experience something that can be considered fairly intelligent, efforts are being made to ensure this goal is achieved.
Two weeks ago, the Official Google Blog addressed the growing intelligence of Google Search Algorithm as it can now identify synonyms.
A good example is “Pictures” and “Photos” which are now treated as similar in meaning.
An acronym like “GM” will not lead you to General Motors website anymore, because Google will understand that “GM” may have one than one interpretation through synonym identification. Therefore, GM may mean “Genetic Modification” rather than “General Motors.”
Through the keyword crop, Google will interpret that the user intends to obtain information on genetically modified crops, and not General Motors.
In the same way, GM car will not lead you to genetically modified crops. It’s best to give this a try on your own in order to experience how artificial intelligence works on Google.

The web is growing in intelligence, as there are now many websites built on Web 3.0 which personalizes your search.
A Wide Area Network (WAN) is a telecommunications network that covers a wide geographical area. It connects multiple Local Area Networks (LANs).
It can also be defined as a network that extends across a public network or commercial carrier, using one of the numerous WAN technologies.

Main Components of WAN

Routers, switches and modems are the main components of WAN. They are described in the hardware section below;
CPE: Customer Premises Equipment (CPE) are devices on the subscriber premises. The CPE is either owned by the subscriber, or leased from a service provider.
The CPE is connected to the service provider’s nearest exchange or central office by a copper or fiber cable. The cabling is usually called the local loop, or “last mile.”
DTE/DCE: Data circuit-terminating equipment or data communications equipment are devices that put data on the local loop.
Data Terminal Equipment (DTE) are customer devices that pass data to the DCE. The basic function of the DCE is to provide an interface into the communication link on the WAN cloud.

 

Hardware

Various types of hardware are required for the WAN to function. Examples of the type of hardware needed are:
Router:

the Router connects the Local Area Network (LAN) to the Wide Area Network (WAN) and takes care of routing messages between the two networks. It operates at the 3rd layer and uses IP addresses to make decisions.
Switch:
this is a network device that chooses a path or circuit for sending a unit of data to its next destination. Operates at the 2nd layer, and sends data to the right destination using MAC addresses.
Modem:
Literally translates to modulator/demodulator. It enables communication between a computer and other computers over phone lines. It operates at the first layer where transmission and reception are achieved by converting signals from digital to analogue and vice-versa.

WAN Standards:


WANs work within the OSI model using layer 1 and layer 2 levels, which are the data link layer and the physical layer. The electrical, mechanical and functional connections provided are described by the physical layer protocols.
Encapsulation: When data is wrapped in a particular protocol header, it is referred to as Encapsulation. The range of WAN specification types such as SDLC, PPP, Frame Delay and others must be specified manually.
Packet and Circuit Switching: Both are used in high capacity networks. Packet Switching provides data most of the switched networks. However, Circuit-Switching which is older and more expensive is more reliable than packet-switching.
General Routing Issues: Routing Protocol The routing protocol explains how routers communicate and exchange information on a network. Changes are dynamically adapted to the network connection using RIP by routers. They also provide information on which networks can be reached by routers, and the distance between them. Routing Algorithms Distance Vector Here, his router informs other routers of their routing table. Another name for the distance vector protocol is bellman-ford algorithm.

Link State


Here, each router retains some part of the network map. It is also called Djikstra’s algorithm. IGRP The IGRP was invented by Cisco and is used to exchange routing data in an independent system.
Addressing and Routing Routing simply refers to the process of determining how to move packets from one network to another.
IP Addresses Every desktop computer, laptop, iPad or mobile phone has an Internet Protocol address. They are displayed in decimals to make it easier for humans to understand them. Octets are the four numbers that separate them.\
Sub netting This allows the creation of numerous networks within a class A, B or C address. LAN uses the subnet address.

Circuit Switched Leased Lines


This sets up a dedicated channel between nodes and terminals before users can communicate. Packet Switching Messages are broken up into small packets before they are sent. The packets are then sent individually over the internet. Mobile and Broadband Services Digital Subscriber Line (DSL) is deployed to bring high bandwidth connections to homes and small businesses through a copper wire telephone line.

Asymmetric Digital Subscribers Line This is commonly used in households.
Symmetric Digital Subscriber Line This runs through a pair of copper wires and is a digital subscriber line.
Advantages of Using DSL

-Instant virtual transmission of voice, data and video over something as simple as copper phone lines -Cuts out delays in information and graphic internet download -Provision of inexpensive high speed internet connection -Constant on-line presence
