Oh no no home users can expect to get 100% of the speed they pay for cause they have their own ONT per house. it’s not like some business that share a single fibre connection accross multiple buildings.

 

I'm honestly not sure what to say in response to that because I'm assuming it was merely a sarcastic response?

I remember reading the Chorus document for my fibre connection just before I got it and it says the CIR (Committed Information Rate, I think) is 2.5 Mbit/s for each connection.  That is enough to guarantee that your VOIP will keep working properly if you have it set up to use the right DSCP priority value in the IP headers, which I think I have done.  Any IP packets with that DSCP value will be sent by the ONT using CIR bandwidth and will get through as that much is allocated to you only.  But any bandwidth beyond the CIR (2.5 - 1000 Mbit/s in my case) is shared with anyone else using the same path through the Chorus network.  They do provision reasonable amounts of bandwidth, but not nearly enough for everyone who is using that bandwidth to run their fibre connection at full speed at the same time.

well I always get my full 200Mbps down on speedtest.net sometimes I don't always get my full 20Mbps upload but then sometimes I get more .. up to 40Mbps sometimes. I've does multiple speed tests on different days and at different times and always get the full 200Mbps down which leads me to believe you always get the full speed that you pay for. I don't believe that my fibre is shared with my neighbours like @sbiddle seems to think... I know it was like that with copper but not fibre everyone gets their own dedicated line.

Log a fault my dude Chorus told me you will get the speed you pay for.

 

 

google GPON, and then apply a 16 split to it, work out what that gives every connection the you will see its impossible for everyone to get full speed all the time.

Say whattttttttt? Just cause they have their own ONT in the house does not mean 100% plan speed 24/7

excluding maintenance and faults... fibre seems to be pretty rock solid.

@Starscream122 Best stop here as you're very very incorrect. Have a look at this Wikipedia article about GPON - It is split fibre (via a prism) and shared bandwidth divided up to 32 people in older UFB areas. Nobody gets their own "dedicated" line. I know you're trying to be helpful and we endorse that from everyone but honestly please do quick Google searches on things if you're not 100% sure as you've railroaded a few threads now.

Yes fibre is rock solid as expected as speed is not impacted like copper over distance and many other factors but you really need to stop offering advice on things you are not sure on

@Starscream122 you likely still get full speed because the GPON connection is not fully or overutalised yet. put 3 people on it with 1gig connections all downloading at the same time then see what happens to your connection.

 

if every single person off the prism had a connection its about 155mbps per person all downloading/streaming at the same time. but the likely hood of having all 16 connections connected at the moment is small as is the likelyhood of all 16 connections using their max downstream at the same time. by the time that gets higher and things become "more congested" chrous and other LFC's will likely have rolled out 10GPON so that would give everyone 625mbps.

@Jase2985 So what you're saying is the only reason I am getting my full speed is cause I am in a newer fibre area and not everyone in my street has connected to fibre or they have but they aren't using gigabit connections?

 

Maybe they take the speed off people that have gigabit to give to lower plans so that people that pay for 100 get 100 etc and gigabit plans get ''up 2'' a gigabit

You put every single house house around you on Fibre then watch the speed drop off at times

Kinda correct.. The CIR uses 802.1p tagging, not DSCP. This can also only work if your connection uses VLAN tagging, since you can't use 802.1p tagging without a 802.1q VLAN.

 

The CIR is also separate from your EIR (the "headline" speed), and there is no CIR component to the EIR on most residential plans. Your entire headline speed is all best effort.

maybe, like i said there would be very few areas where all 16 fibre connections would be connected, and also where people are using their connection to the Max 24/7. on the 155mbps i mentioned thats 1.6TB per day of downloading. or 6 4k streams at the same time. its a lot of data.

 

they dont do what you are suggesting in the second paragraph.

 

you are not guaranteed anything on your connection, look at the wording, speeds up to xyz. fibre is a best effort service, bar the dedicated 2.5mbps for a VOIP connection which is guaranteed. you may not get the speed you paid for 100% of the time. if you currently are great but you may not going forward as more people connect up and use more and more data.
