Hi All,

Does anyone know any of the technical details behind what fiber is being rolled out across the country?

What mode is used: Multi-Mode or Single-Mode?
What wavelength is the defacto: 850nm, 1310nm or 1490 nm?

I have asked the technicians (and their bosses) that are installing it in my area, but all of them have no idea.

The reason for this is I want to make use of a Mikrotik for the setup, such as this: https://mikrotik.com/product/RB962UiGS-5HacT2HnT
But it requires a specific SFP module that only supports one of the above modes and frequencies, and obviously I do not want to buy one of each :P

I would guess Single Mode, as the fibre patch lead on mine is yellow, which is the industry standard.
 
I am not 100% sure but wouldn't you need a GPON SFP like thishttps://routerboard.com/SFPONU. And then I would guess that you need your ISP's help to configure it which they may not want to do. But like I said I'm not 100% sure - more like 50% sure.

Maybe other form memebers would have more knowledge

Across the country? You do know there are multiple providers some of whom differ from each other. You are further aware that the provider and ISP both care little for your router, and the fibre provider in particular will not allow you to plug their fibre directly into your router? As in the fibre provider will terminate the fibre into their ont, with an ethernet (copper) hand off to the ISP.

If it is PON networks (single fiber strand), you can not use your own router to connect the fiber to. You must use their FTTH modem.

Only Vuma currently does not use PON (to my knowledge), and there, you may (not even guaranteed) get away with your own fiber router. In that case, you'd need a 10KM, Single-Mode SFP.

Nope. TT Connect also do point to point, and them and Vuma will not let a rogue or at least unmanaged router onto their networks. The op must just get over his ego.

Ah ok. Good to know there's at least one other AON player out there. Vuma used to be the only one then ;)

EDIT: And yes, fully agree, it's highly unlikely they would allow you to use your own modem / router.

I worked for TT and am now with sadv. They will not let you terminate into your own kit. They/we will terminate into something and then it's up to you/ISP.
 
With how they do the SETUP with ONT and PPPOE Details (most ISP) you really do not need to terminate on your own Mikrotik router you can do all the port forwarding etc from the PPPOE and on Vuma i am pretty sure they have some sort of DMZ forwarding to your own router off the ONT.

If its a speedwise worry i am sure the ONT's they install can handle upto 1GBps otherwise they wouldn't use them as many clients would complain haha

I was hoping there would be a nice list of the various vendors, or a common standard :whistle:

Not so much about ego as not wanting an unmanaged device on my network :P Guess it goes both ways :crylaugh:

If your own kit matches theirs in specification, what effect would it have on the network? Do they also do alot of active management of the devices?
 
For what it's worth, here is the Raycore router and SFP supplied by Vumatel.

The unmanaged device will not be on your network. You end at your router. And it's managed by the ISP...

It's not about specs. It's about end to end testing. You phone them and tell them "it's not working", they need something on your side to test the connection with. They can't be expected to provide technical support by supporting thousands of different type of equipment, and neither are there guarantees that the private router you may use, have all the support utils built in that they need. Therefore, they supply the CPE to provide a standard on their network, which they manage in order to facilitate the management and support of the LINE. This has nothing to do with your Internet Access (Layer 2 vs. Layer 3).

It's not your network, belongs to the provider and they manage their terminating equipment. What you connect to their ethernet port is yours and you can do with as you please.
 
Just for the record, I plugged my Direktronik SFP GBIC directly into my Mikrotik and it worked. Vumatel with Access.

Thank you! I just pulled out the GBIC and put it into my main Mikrotik router and it's working beautifully woohoo :D Now my whole network will run off battery when load shedding happens... at 4pm.
 
Less equipment with power supplies that go faulty is always a better option.
 
Hello Hello and Good Locked down Sunday morning,

My broadband has helped me in sooooo many wayz!!!!
Google sucks!

I've got a vumatel fiber line running 200/200 seacom package. Seacom supplied us with a TP-link Archer 1200 router, which is nice when you are small business or perfect for home use!

But like with my system, that is used to feed 130 students and the most devices connected I've seen is 415, that TP-link is not made to handle it.

Now I'm going to recently take out the ont, plug the GBIC straight into my mikrotik router and then not have the endless headaches of students kakking me out at 2AM in the morning because they can't connect!!!

Out of curiousity, how has that worked out for you?

Are you still doing it that way? Does it just show up as an ethernet interface on your Mikrotik, or do you need to do any configuration of the interface beyond obtaining a DHCP address? Have you had any service interruptions that would necessitate Vumatel testing against their Raycore CPE? Has Vumatel said anything to you about not being able to reach their CPE?

No problems at all actually. The interface on the Mikrotik is 'sfp_fibre'
