Any luck with this, diablonet? Did you manage to get your sfponu to work with your isp?
Looks like you may have a defective SFP module if it isn’t even recognized by your Mikrotik. You can also try looking under the webfig to see if you get additional information.
It didnt worked, my device is not allowed to connect into my ISP network, they need to register my device but I dont know how to get the Mikrotik GPON S/N.
Mikrotik GPON serial printed in the device: 15 digits, example: FG1537TWGPA04T8
Alcatel GPON serial pattern (my ISP device): 4 letters + 8 hex digits (starting with ALCL, brand shortname), example: ALCLF0824B23
as ToTheCLI suggested maybe it is a Mikrotik GPON serial like this inside the device: MKTKxxxxxxxx (x being hexadecimal digits) and MKTK a brand shortname, witch matches my ISP serial patter (8 hex digits), but we dont know how to get this since it is not printed in the device and not shown in the Mikrotik, maybe Normis can clear this up.
You don´t need know your S/N. Conect your GPON module to ISP network. Then call your ISP.
He sees a new client in the “OLT discovery” and register it.
You will not believe how “amazing” my isp is related to support, if you call the service number, the operators are clueless…
Most likely you need to get to higher level support, try to get to the tech people, no the call center
It seems now with the latest version of Mikrotik (now on beta) you can see the GPON serial number:
*) ethernet - add option to see S-GPON-ONU module, GPON side SN in “/int eth mon sfp#”
I suspect all efforts will go nowhere unless your upstream ISP configures their device to talk to your device.
For my head-end, I use Adtran TA-5000 units. Every new ONT connected and every replaced ONT connected requires some admin configurations be made when a new or replaced ONT is connected.
If I had a customer asking if they could use their own ONT, I would think about it and possibly want to test it, but in the long run, I would NOT support it - unless the ONT came from me.
There are just way to many one-off things needed for a one-of-a-kind customer owned ONT. Such as management, NAT, bridge, SIP, and QOS rate-limiting bandwidth control, network monitoring and automatic firmware and vendor configuration upgrades - and potential security issues on the GPON network.

What if we need enter password for ISP to work with it ?
There is no option to enter password, like on TP-Link GPON external device ?
Our supplier “Titan Wireless” does not have any Mikrotik GPON sfp adaptors yet. So I am unable to order one to test it out.
However, from what I would guess… I would suspect the GPON adaptor would not need a password. I suspect it would almost be transparent on the client side and would function very close to a normal SFP adaptor Ethernet interface. They might be some SFP diagnostic information to the client router/switch/Mikrotik-device. Most of the intelligent configurations would likely be made in the ISP upstream GPON head-end equipment. But even then, when I configure a new ONT to work on my GPON network, I have to configure the following:
- ONT (GPON) serial number
- Line Card
- Port
- ONT number in the GPON pool
- Connecting Ethernets on the client ONT device
- Bridging - or Residential Gateway
- ONT diagnostic distance and signal strength to/from client ONT
- ONT firmware and upgrades
- ONT configuration file
- ONT bandwidth control up/down limits
- Ability to remotely reset/reboot the ONT
- Ability to remotely connect and execute diagnostics on the remote ONT
- SIP (VoIP) ((( A problem with Mikrotik not supporting SIP devices )))
and the list goes on and on… - ONT Power status (on battery ???) and how to function if power is out and running on battery?
Normally the upstream ISP has control and access to all of the above items (and much more).
After thinking quite about this, I might even consider it a potential GPON network security issue if 100 percent of the customer ONTs do not come from my ISP and managed by my ISP.
My point is that an end user trying to replace their GPON connected ONT with a Mikrotik using a Mikrotik GPON adaptor without their ISP working with them may be a go-nowhere process. The Mikrotik ONT GPON sfp adaptor is more of an upstream ISP tool and product which can be used with/for ONTs fully owned/managed by the ISP - not the client.

Thank you Tom Jones, your info is very helpful, I have 2 brand new Mikrotik GPONS, that I cant not use, kinda brick for now 
Maybe at some point, my ISP will support it.
You would be more than welcome to donate them to me for GPON testing 
What did they cost you ?

I do not understand, why is not possible to make configuration of GPON, like TP-link GPON adapter have, http://www.tp-link.com/res/down/doc/TX-6610_V4_UG.pdf , because there are obviously many ISP that require this autentification to work with GPON

I am guessing that screen may be related to some type of a PPOE login. Where the device/user has to supply a login & password to connect to the network. This really has little or northing to do with the ONT serial number seen at the upstream ISP.
I do not use PPOE. If I did, then I would suspect to configure a new ONT customer client, I would then need the ONT serial number I would see from the customer ONT device to allow it to connect to my network. Then the PPOE login/password information to allow the traffic to authenticate to my network.
My guess is
1st - the upstream ISP GPON network equipment must see the GPON serial number (and that serial number be configured in the head-end ISP equipment. Like a layer 1/2 physical connection.
2nd - the PPOE login is then used to authenticate the customer IP connection at a layer 3 level.

I got them from here: http://www.ispsupplies.com/brands/Interfaces/SFP-GPON-ONU.html
Paid $89 USD each + shipping to México.
I will keep them in case my ISP support them.

No, this password are not PPOE login, these are GPON password to autentificate with ISP.
As told in TPlink manual: “Do not mix up the user name and password with your Terminal account user name and password which are needed for PPP connections”
Thanks - learned something new…
My GPON system (Adtran TA-5000 units with iPhotonix ONTs) do not have this - that I know of. I have user/password to admin my Adtran and user/password to admin my ONTs - and the Adtran also has some ability to admin the ONTs.

how to set gpon LOID?
I am here to support LOID certified in the ROS in the correspondingauthentication interface?
Was originally looking for GPON ONU module, look at this situation, bought does not take, or forget. TP-LINK is a good, cheap and easy to use, good compatibility.
