A. FTTH (Fiber to the home) is the delivery of a communications signal via optical fiber from the operator’s central office all the way to a home or business, thereby replacing existing copper infrastructure such as telephone wires or coaxial cable. Fiber to the home is a relatively fast growing method of providing vastly higher bandwidth to consumers and businesses, and thereby enabling HDTV, IPTV, internet and voice services. current fiber optic technology can provide two-way transmission speeds of up to 1 gigabit per second, with 10 gig systems now coming to market and even higher bandwidth fiber networks now being developed.
GTTPL is the pioneer in FTTH networks and has been using them for far longer than most other service providers in this field
Q. What is optical fiber and optical fiber cable?
A. Optical fiber is a hair-thin strand of glass, specially designed to trap and transmit laser pulse. The fiber uses light instead of electricity to carry a signal. It is unique because it can carry high bandwidth signals over long distances without signal degradation, and it can provide those signals simultaneously in both directions – upload and download. Copper media can also carry high bandwidth, but only for a few hundred yards – after which the signal begins to degrade and bandwidth narrows. Optical fiber has been used in communications networks for more than 35 years, mostly to carry core telecom traffic from city to city or country to country.
An optical fiber cable is a cable containing one or more optical fiber cores that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Different types of cable are used for different applications, for example long distance telecommunication, or providing a high-speed data connection between different parts of a building.
Q. Why is fiber optic cable now being connected directly to homes?
A. Connecting homes directly to fiber optic cable enables enormous improvements in the bandwidth that can be provided to consumers, both now and for many more decades of accelerating bandwidth demand. While cable modems generally provide transmission speeds of anywhere between five and 50 megabits per second on the download (and are generally much slower when uploading), current fiber optic technology can provide two-way transmission speeds of up to 1 gigabit per second, with 10 gig systems now coming to market and even higher bandwidth fiber networks now being developed. Further, while cable and DSL providers are struggling to squeeze small increments of higher bandwidth out of their technologies, ongoing improvements in fiber optic equipment are constantly increasing available bandwidth without having to change the fiber. That’s why fiber networks are said to be “future proof.”
Q. Why do we need all that bandwidth? Aren’t cable and DSL systems good enough for what most people want to do?
A. This is the age of video over Internet. Increasingly, consumers are using their Internet connections to view television programs from content providers like Netflix, Hulu and Amazon, in addition to the growing number of websites that provide video in some form. Over the past several years, since in the introduction of the video sharing site YouTube, video has grabbed an ever-larger share of total IP traffic and is now the Internet’s leading application. One high definition movie takes up as much bandwidth as 35,000 web pages. In the meantime, a growing number of companies are offering “software as service” – meaning you subscribe to applications on the net rather than install them on your own computer. These “cloud computing” applications are now available for word processing, emailing, automated remote file backup, and a host of business and personal services. All of these applications – and many others we haven’t even dreamed of yet – are going to require much greater bandwidth than what is generally available today, even from “broadband” providers. While many cable modem services have thus far kept up with steadily growing consumer demand for more bandwidth, DSL services have struggled to do so. And it remains to be seen how much longer cable modems, which use copper in the last-mile, are going to be able to keep pace – especially given Cisco’s forecast that IP traffic will grow at a compound annual growth rate (CAGR) of 34 percent in the years to come.
Q. But is a 100% fiber network really necessary?
A. We have no reason to believe that innovation in Internet applications and services will ever slow down – in fact, all signs point toward their acceleration as high-definition video, telemedicine, distance learning, telecommuting and many other broadband applications come to market. Only fiber to the home is going to be able to deliver the bandwidth we are going to need far into the future.
Q. Are fiber to the home services more expensive than those that are available over cable modem and DSL?
A. Our surveys have shown that FTTH subscribers pay approximately the same for their Internet, voice and video services as do customers of DSL and cable providers, and that FTTH subscribers actually pay less per megabit of bandwidth that they receive. In addition, surveys of broadband consumers conducted by Consumer Reports magazine and by the FTTH Council have shown that subscribers of FTTH services show considerably higher satisfaction rates than subscribers of other broadband services.
Q. I’ve heard that wireless technologies like WiFi and WiMAX can deliver the same kind of service as fiber to the home without having to go through the trouble of installing new wires into homes. Is this true?
A. No. Wireless broadband is subject to spectrum availability – the cost of which limits the bandwidth, and hence the applications it can provide. These wireless technologies cannot deliver high definition television – and, in fact, they have trouble delivering standard television. And HDTV is only one of the many high-broadband applications now being developed for our broadband future. Wireless will always be a useful mobile application adjunct to FTTH.
Q. What about satellite? Most people have that choice, don’t they?
A. Satellite offers video, of course, but it cannot offer robust broadband Internet service because the subscriber can only download the signal. Upload is normally provided through the subscriber’s telephone lines, which limits transmission speeds for user generated content.
Bandwidth is defined as the ABILITY to transfer data over a connection in a specific period of time (measured in seconds in this case) Customer always assume that the pipe is constantly thick on the opposite end and everything depends upon their end of the package subscribed for
Bandwidth is dependent on the thinnest part of the connection which may not necessarily be the bandwidth package the customer has subscribed for
For example in an idealistic example
if a customer has subscribed for a 10Mbps package and is downloading from a server which has a 100Mbps link to their ISP, the max drawable data will be at the rate of 10Mbps
However even if a customer has subscribed to a 20Mbps package and downloads from a site with a 10 Mbps connection, he will get only 10Mbps despite having a larger package
In telecommunications, broadband is a wide bandwidth data transmission with an ability to simultaneously transport multiple signals and traffic types. The medium can be coaxial cable, optical fiber, radio or twisted pair.
In the context of Internet access, broadband is used to mean any high-speed Internet access that is always on and faster than traditional dial-up access.
Report On Need for Reviewing Definition of Broadband
In India the Broadband policy was formulated in 2004 which defined broadband connection as an always-on Internet access with a minimum speed of 256 Kbps from the POP of service provider to the customer premise equipment. Through its Recommendations dated 8th December 2010 on National Broadband Plan, the Authority recommended the following:
Broadband connection may be defined as
“A data connection using any technology that is able to support interactive services including Internet access and support a minimum download speed of 512 kilo bits second (Kbps)” .
6.22 It is to be noted that the upload speed will at least be half the download speed. This definition of broadband (Both wireline and Wireless) given in para 6.21 above, will be effective from 1st January 2011. The stipulated download speed of 2 Mbps will be effective from 1st January 2015.” (emphasis supplied)
The Department of Telecommunication (DoT) revised the definition of Broadband through its notification date July 18, 2013 which is as follows:
“Broadband is a data connection that is able to support interactive services including Internet access and has the capability of the minimum download speed of 512 kbps to an individual subscriber from the point of presence (POP) of the services provider intending to provide Broadband service.”
The Advantages Of Leased Lines For Small Businesses.
(credit) - FRAZER LLOYD-DAVIES
What Is a Leased Line ...?
The majority of businesses are reliant upon the internet. Without it, few could function efficiently. As a result of this reliance, many small businesses are exploring their options when it comes to their internet connection. We believe that in most instances, a leased line is the best option. In this blog post, we take a look at the advantages of leased lines.
Dedicated internet connection.
The main advantage of a leased line is that it is a dedicated internet connection. Other local businesses and residents do not share your leased line internet connection. This is unlike broadband or fibre. As a result of this, leased lines have fixed bandwidth, which doesn’t fluctuate at peak times. In other words, the internet won’t go slower at busiest times of the day!
Service level agreements.
Another major advantage of a leased line are service level agreements (SLAs). These agreements dictate the minimum level of service you can expect from your provider. They also outline the level of compensation on offer, in the event of a fault. Therefore, should you have an issue, that isn’t rectified promptly, you will be aware of what compensation to expect. Most other internet connections will offer limited compensation, if at all, in the event of a problem.
Higher upload speeds.
When businesses consider an internet service, they seldom consider upload speeds. Domestic internet services have much higher download speeds compared to upload speeds. With a leased line, however, these speeds are identical, which is a massive advantage. Upload speeds determine how quickly you can send data. The higher your upload speed, the more efficient (and quicker) the overall connection is. In the workplace this means it’s easier to send emails, access data on servers and make VoIP calls.
What is Contention Ratio ?
As per Wikipedia
In computer networking, the contention ratio is the ratio of the potential maximum demand to the actual bandwidth. The higher the contention ratio, the greater the number of users that may be trying to use the actual bandwidth at any one time and, therefore, the lower the effective bandwidth offered, especially at peak times.
A contended service is a service which offers (or attempts to offer) the users of the network a minimum statistically guaranteed contention ratio, while typically offering peaks of usage of up to the maximum bandwidth supplied to the user. Contended services are usually much cheaper to provide than uncontended services, although they only reduce the backbone traffic costs for the users, and do not reduce the costs of providing and maintaining equipment for connecting to the network.
i.e. if a person buys a 1:20 ratio pack of 1Mbps, at peak time 8 people would be vying for that 1Mbps simultaneously
In India the DECLARED contention ratio of our competition for broadband goes upto 1:40 or more.
GTTPL at 1:30 is still 25% far better than competitors at an approx benchmark of 1:40
What is FUP ?
FUP also known as Fair Useage Policy this concept was introduced to make sure that a few customers who were heavy users didn't fill up the available bandwidth, making the overall experience bad for others on the same network
As per a survey, the average useage was approx 26GB per month per household pan India. The word "average" covers a wide spectrum of users from those who download constantly to those with a base use of applications such as Whatsapp, etc only
In reality, the FUP limits are unrealistic for any moderate to heavy user and can be easily exhausted by watching few hours of YouTube or Netflix everyday. (All the family members combined). Especially for those who prefer YouTube / Netflix / other Streaming services over cable TV.
At GTTPL. our average client useage is 100GB per month or more. This is due to a high customer profile base of expats and discerning clients, so its recommended that any package an average user may by on our network should be at least over 100GB
What is the difference between your Residential and Commercial Plans ?
GTTPL has 2 kinds of broadband clients. The first are the customers who expect international quality and are aware of the fact that each mobile phone, each tablet, each PC, smart TVs and many more devices consume bandwidth in the background. They are those who work on international levels with VPNs, and want to watch streaming services like Netflix and You Tube and many more new ones like Amazon Prime in HD. For these these customers, the contention ratios have to be as low as possible without opting for a leased line, for these customers GTTPL
For the other set of customers GTTPL are commercial establishments who wish for competitive pricing and need high reliability lines but are able to adjust with slight downtimes. Leased lines come with an uptime of 99.9% whereas broadband is on a best effort basis
I have purchased a multimonth FUP pack,can the the free data transfer be used in a shorter period?
GTTPL FUP packs are based upon the total High speed FREE data transfer for the complete period subscribed for and can be used in a shorter period after which the speed would revert to the lower floor level.
The period overall remains constant , however time in which the Free high speed data transfer is used is variable based upon client usage
For example - a purchase of a Gold pack of 6Mbps 150GB (max valididty 3 months ) means that 150GB could have been used in 45 days and the rest 45 days would be at 1Mbps
I have have exhausted the high speed data transfer and have a time period left, what can I do to go back to a higher speed?
You can buy another pack and ask us to terminate this pack and replace it with the new one (termination of old account carries no refunds) to return to higher speeds
Why am I getting such low speed when I test using my mobile phone ?
GTTPL always advises customers to use laptops directly connected to the Ethernet port of our connection to check bandwidth . Checking the bandwidth using a wireless connection always carriex the danger of other devices such as Ipads, phones etc still using background bandwidth giving you a false reading.
One new procedure which we see very frequently is customers testing connectons using mobile phones. In case of mobile phones, please be sure to go your settings section then > Data Connections and toggle "DATA CONNECTION" OFF
If your mobile shows a H, E, E+ or any other alphabet next to the mobile signal alphabet means you will be testing the mobile network speeds and not ours
