Hi thanks for video. Very informative. Could you give me any idea how I can lease recently laid fibre in my area to become an installer please. I want to try and run my own FTTH business. Thanks Django (South Africa) it just sounds like u r from here?
I know you made this many years ago, but I would like to hear you explain uplink on a PON fiber network. I know it involves timing as if everyone on a PON fiber tried to upload at once there would be a problem. Is the intelligence for timing on the OLT or on the ONT or both? Thanks!
I believe it would be on both but the OLT would take the lead. Given that each manufacturer has their own GPON implementation I'm not exactly sure. It's like everyone trying to make a phone call at once or hospital beds during the COVID-19 pandemic.
It's an ONT an Optical Network Terminal. In most cases no you need to connect it to a router first because the ONT usually uses what is called a PPPoE connection so unless you connect it to your computer or laptop you can't use it. Think of the ONT like a modem.
thank you for the explanations and for shattering the myth (well my myth) that i thought Fibre was always relitively the same speed and didnt suffer from contention like ADSL - I was wrong then , so there will be a noticeable drop at peak times then even with FTTH ? Also you say on the PON that the light is split by prism to split the signal to others on the network yes? - if that prism got dirty or 'cloudy' over time say, like other glass gets would that/could that actually cut down or block the fibre optic signal then?
It could, but the chances of the optical splitter getting dirty are extremely low. I actually have never seen an optical splitter get dirty or cloudy. They have been used for decades, by every cable company in the world.
3 types for optical network P2P, AON, PON P2P (N users has 2N transceivers+ N optical fiber) AON (N users has 2N+2 transceivers+ 1 optical fiber) PON (N users has N+1 transceivers+ 1 optical fiber) THANK YOU FOR YOUR EXPLANATION
Greetings “OpticalNetworker”, A question if you please: Would you be able to say whether BT's [in the UK] new 300Mb/s offering of FTTH is Ethernet or E/G PONS-based? Keep up the good work. Ii is very understandable that there is, sometimes, so much “Up There” that the information are unable to be relayed easily. Meaning that you ae not “Tipsy” other than being “overloaded-mentally”. Thank you.
