M1 FIBRE BROADBAND DISCUSSION - Part 2

[Coaster]

Three types of ONT from M1.

1) GPON ONT for 500Mbps/1Gbps/2Gbps plan: Huawei HG8240 or a smaller variant (with one active 1G port; two active 1G ports for M1 2Gbps plan)
2) GPON ONT for 2.5Gbps plan: Huawei HG8240N [with one active 2.5Gbe port]
3) XGS-PON ONT for 3Gbps/6Gbps/10Gbps plan: Huawei OptiXstar HN8250Ts-20 [with one active 10Gbe port].

The above does not include one the legacy XG-PON ONT --> Huawei HN8055Q for old 5Gbps/10Gbps plan which were offered for a short time.

So moving from 1GB to 3GB plan, M1 will send me a new ONT ? And I just switch the ONT ?
Do I need to return the old ONT ? Then I cannot switch at my own time if the person is waiting to collect it.
Do they also have to do anything changes outside my house that I need to time my ONT switching to ?

Technician will visit to install the new ONT.

No need to return the old ONT.

If you were upgrading but retaining the same ONT, a visit wouldn't be necessary.

In this case, not only are you swapping the ONT, you are also upgrading from GPON to XGS-PON. The technician will want to check the quality of the signal from the NBN.

You can try visiting an M1 shop to inquire about self-install.

Oh, I spoke to M1 previously. Think they don't know what exactly is happening on the ground. So trying to find out from people here. The M1 agent said they need to do some testing, I wonder if it's necesary. Prefer to change myself, if it's a simple switching.


Btw, if I change the ONT before the "turn on" date, the new ONT will work with 1GB ?

XGS-PON and GPON operate on different wavelengths, which allows them to coexist on the same fiber network.

That doesn't necessarily mean the OLT or ONT support both modes.

In the case of M1's ONT (Huawei HN8250Ts-20), it only supports XGS-PON wavelength, so you can't use it with GPON.

Free onsite installation by M1. They need to test the signal is ok too.

Thanks for that info

Oh... then definitely must find a time nobody using the network... thanks !

Testing and overall setup should be very fast. downtime may be less than 30 minutes.
The techs just make sure that the wavelengths that you need can be detected accordingly.

Only take 30mins or less, u running mission critical work at home?

 

[twosix]

Actually takes 10min or so if not installing wifi router.

Today M1 technician came to replace ONT for my upgrade from 1G to 6G.

The new ONT model (Huawei HN8250Ts-20) is per what xiaofan stated. M1 technician also provided a new yellow SC-connector cable to connect your new ONT to TP. A new CAT6a RJ45 cable was also provided to connect the new ONT to the router.

Old ONT model can keep. Do keep the old ONT power adapter and the old yellow SC-connector cable to TP, you can use as backups for the new ONT if case the new ones provided spoil anytime in fture.

You can also request to use your own router, M1 technician will still test that the speed from TP to ONT to his own M1 laptop (via ethernet connection) is correct and expected, per your upgraded plan speed.

Lastly, the M1 technician very nice, gave me a free additional CAT6a RJ45 cable when I requested (same as the one provided as part of new ONT), to keep as backup.

Above is to share my experience with all, since the people helped answer my questions here recently when I asked a few.

Just curious for my general knowledge,

What is the difference between OLT and ONT?

The ones in consumer' homes are ONT (or ONR if integrated with router) right? Then OLT is located at the telco's premises?

OLT is the mothership, the one sending those optical signals that the technicians measure in that small white box in your home.... the ONT is the "slave", it's the equipment that converts the optical signal back to electrical signal, the one that your devices can understand.

OLT = ISP side
ONT = Subscriber side

The 6 Gbps is it negotiated using 10Gbps then cap to 6gbps? I supposed 5gbps port should be able to get max speed?

Please do not confuse yourself with your ROUTER PORT SPEED and Internet speed (Data Transfer Rate).

1. THE HIGHWAY - You have these following "PORT SPEED" 10 mbps, 100 mbps, 1000 (1 gbps) , 2,500 (2.5 gbps) , 10,000 (10gbps)
> These port speeds are the SPEED that the port can support, and both ports from your ONT and Router should have the same port speed, if not, they will negotiate to a lower speed....

2. The CAR - the "10gbps","5 gbps", or "2.5 gbps" advertised by your ISP is your "Data Transfer Rate"


So if you subscribe for 6gbps, they should give you a ONT that has a 10gbps port, then this ONT will be connected to your router..... YOU MAKE SURE that your ROUTER has a 10gbps port.... otherwise they will negotiate.

if you have a 10gbps ONT but you used your old normal 1gbps router.... your router and the ONT will negotiate and they will both use 1gbps...

for your 6gbps subscription, they can give you a 10gbps ONT, and you should also get a 10gbps ROUTER....
this way you will get your 6gbps... YOU NOW have a 10gbps highway, then "YOUR CAR" can max out its 6gbps potential....


Remember 10gbps > 2.5 gbps > 1 gbps > 100 mbps > 10 mbps, these are your only options (at least for the consumer range)

Regarding the above, if ISP give you a 10gbps ONT for a 6gbps plan, but you use a router with only 2.5gbps WAN port, then ur max speed output is capped at 2.5gbs right?

That is correct, because now you are limited to the speed of your router.

You are only as fast as the slowest port.

Also remember, there are older CAT cables that can only support 1gbps, so even if you have 2 10gbps port, it’s the cat cable that decides

ONT: Nice meeting you Router, i can do 10gbps
Router: Sorry ONT i can only do 2.5gbps
ONT: It’s okay, let’s do 2.5gbps then
ONT/Router: Hey CAT cable, you can do 2.5gbps right?
CAT: I’m only CAT5E, at most i can do 1gbps
Then they all agree to do 1gbps.

in reality though, before the ont and router talk, it’s the cat cable who carries the message of negotiation, and if you are asking a boomer CAT cable to carry a genZ message, the cat cable may not be able to deliver that message correctly, so the genz ont and router will try to adjust their “language” until the boomer CAT cable can understand and deliver the correct one. Once they figure out the language the CAT cable can understand and deliver, they stick to that

Just to add on. Its not necessarily set in stone that CAT5e = 1Gbps max. My 10m~ CAT5e run does 2.5Gbps with no issues.

is that a speedtest ? They do it directly from ONT, right ? I don't need to set up my router first, right ?

I need to move a bit of furniture to connect to the port. And before that, I need to use the internet. So I have to tie the timing of when the technician coming and when to start moving things.. abit of dependencies.
