Well almost here, this one is from a dude in US.<br /><br />Posted by timothy on Tuesday October 26, @07:18PM<br />from the sneeze-at-cat5 dept.<br />ooglek writes "Verizon is now qualifying and accepting installations for FTTP (Fiber To the Premises)! $39.95 for 5MB/2MB, $49.95 for 15MB/2MB, and $199.95 for 30MB/5MB. No word yet on whether Verizon will block ports (25, 80, etc) for incoming or outgoing traffic; with 2MB upload, I hope to basically run a small data center in my basement. Both phone and Internet will come through the fiber, and there is an unofficial rumor of video services as well by the end of this year. Got Fiber? My install date is November 2nd in Falls Church, VA (near DC). Several people in Keller, Texas have posted pictures and reported 14,679 kbps download and 1,794 kbps download speeds." Update: 10/26 23:52 GMT by T: That second "download" ought probably read "upload."

well Nick dont expect to see fiber for the masses just yet in australia as it is to expensive to install for home use <br />dont for get that you will need 2 fibres per house as it is typicaly a one way system if you want to use it two it slows it down a bit <br /><br />and dont forget it is not completly secure it can be taped easly <br /><br />ADSL and Cable are our best bet for the time being <br /><br /><br />end of line

Like Jason said, don't expect to see FTTP for quite some time in older houses. It is only being installed in a new estate in queensland as a trial for the technology.<br /><br />FTTP will allow the customer to have 4 POTS (plain old telephone system), broadband internet (still with a 1.5Mb/s limit) and pay tv. It also requires a small UPS to be installed in the house for power outages.<br /><br />It will be only using 1 fibre to the house. How's does 1 fibre work? Shine two torches directly at each other, you can still see the other torch light can't you. Fibre splitter exist in telstra networks for data rates up to 155 Mbits with data flying in both directions on one fibre. You do get small reflect of light from fibre splices and patches, but provided your RX signal is strong enough, the backscatter from the TX wil be ignored.<br /><br />Also with FTTP, thus customer can be up to 20Kms from the exchange.<br /><br />Cheers,<br />Col.

hi Phill And Colin T <br />there are some points that will hold back fibre for all <br /><br />1. with fibre there is also a great saftey concern as it is Laser light in the Infrared range that is invisible and can damage eyes <br /><br />2. lots of $$$$$ to install, terminate, fusion splice, test, <br /><br />3. can the overseas links/backbones handle us all with 100mb/s connections on to it not to mention our own internal links start to don some math and the backbones linke would have to be massive <br />or there will be a big bottle neck it will get pricey <br /><br /><br />in the use off a bi directional fibre link yes it you can get 1.5Mb but i think im am not 100% yet but if you want to have a digital video you need 270mb/s ( or it could be 140mb/s cant rember) for Standard Di and arond 1.4Gbps for High-Def DI i could be mistaken i think that we will still need two fibres <br /> <br /><br />they are installing it in some test suburbs just <br />i think they first install one in canberra and or perth 100mbits system <br /><br />it will come but at a big price and or long time <br /><br /><br />end of line

Hi Phil, yeah its good to be back! Been very busy at work with the federal election lately, but thank the lord it's all over!<br /><br />Hi Jason,<br /><br />The fibre will be terminated in a box outside off the customers house in which only telstra staff will be able access for exactly those safety reasons. From here, it is converted into an electrical signal, RG6 for TV, Cat 5 for broadband and I think KRONE connections for the telephones. (I need to double check). FTA signal for the local TV stations will also be put into the pay TV stream at the local head-end. A STU will still be required to view these channels. Fibre optic cable per metre does not really cost much, but you are right, it is time consuming to splice, terminate and test.<br /><br />Telstra already pushes 2.5G/bit down a fibre for there intercaptical city networks (SDH - Synchronous digital hierarchy) and there is research to prove that it will go faster. It uses Dense Wave Divison Multiplexing (DWDM). Basically using different light spectrums or wave lengths. I also think they push 2.5G/bit on broadband cable (Again, I will have to double check).<br /><br />SDI for digital TV is 270Meg (you can also put ASI in a 270 meg container and ASI is basically MPEG2 within a 270Meg stream) and (SDI) is pure video and audio with NO compression but it has a distance limitation of 200M electrically and 40Kms optically. The transport streams to take digital TV (foxtel and some TV networks) to the different cable head-ends and studios around Australia are on 45 Meg SDH links (DVN Intercapital network). The 270 meg is compressed into MPEG2 and you can get around about 6-10 programs depending on the compression factors and the video quality you want into a 45Meg stream.<br /><br />Again, the only place to have this technology installed is in Queensland. Trust me, I work for Telstra in Media Services and I maintain the ageing analogue network and the Digital Video Network. Although there is no cable network in Canberra (almost was once!) our section also looks after Broadband Cable.<br /><br />If this technology does come to Canberra, and I am hopeing it does at some time in the future, as I will also be working on it.<br /><br />I'll see what pubically released information I can obtain in relation to how the technology works when I get back to work this Tuesday.<br /><br />Also try www.telstra.com and do a search on "Fibre to the premises". I have seen the Tech docos but I suspect that they still maybe Confidential. I'll do may best.<br /><br />Cheers,<br />Col.<br /> <br /> <small>[ 08.
