Hello,
Currently, I have an VDSL connection terminated by an Zyxel bridge and the PPPoE is terminated on an RB2011UiAS-RM acting as a normal router/firewall. Now I would like to move the VDSL connection to FTTH and I do not know whether I should rather take an S-35LC20D SFP or an GPON ONU module one and whether it will work to directly terminate the fiber on the Mikrotik.
From what I was told, the following converter works in Switzerland (https://www.studerus.ch/de/products/cts-cvt-3512-sc-vlan-11/ (datasheet: https://www.studerus.ch/de/support/download/59740_1/_blank), Tx:1310nm, Rx: 1550nm and VLAN 11 for PPPoE). From the wavelength, it seems to match the S-35LC20D SFP and to access the Swisscom FTTH network, I need to tag the traffic to VLAN 11 for PPPoE or VLAN 10 for DHCP.
Does anybody have any experience with something similar or should I go the safe route and buy this converter instead of having all in the Mikrotik router/switch?
Thanks in advance for your feedback

It depends what your provider does use. If its a passive optical network (eg a fixed amount of bandwith shared with multiple customers), which is GPON, you have to use a GPON optic.
Based on the mediaconverter which you’re linking to it seems they are using ‘regular’ fiber links. In that case the optic S-35LC20D should work. Usually a 10 or 20Km optic works fine for FTTH networks.
You only have to add a connection cable. The mediaconverter uses SC type connector, the optic has a LC connector, so you have to order an additional LC/PC to SC/PC singlemode fiber cable. (And possible a SC/PC to SC/PC coupler to hookup to your existing fiber). Depending on the termination unit in your house you might be able to plug a cable directly into it as well.
Verify the connection so you’re using the proper cable. A lot of fiber connections in the FTTH networks (At least in the Netherlands) use SC/APC connectors. (Which is a green SC-type connector).
SC/APC is superior to SC/PC, since it has less reflections due to the angle of the fiber polish. But they are not interchangable.
So: If your FTU uses SC/APC you need to order a SC/APC to LC/PC cable. (LC/PC or SC/PC is usually the type connector used at the optic side)
Also, you’re not limited to Mikrotik SFP’s (Altough they are recommended since they are guaranteed to work). Mikrotik products don’t use vendor locking, so any optic is likely to work.
A lot of users (including me) have good experiences with Fiberstore. And if ordering, you can specific SC/PC also instead of LC/PC connectors.. Saves you an additional cable (which are cheap anyway)
And you might have to upgrade from your 2011, depending on the speed your FttH provider is offering. The 2011 is not really recommended for eg 500Mbit.. Might have to upgrade to a 3011 or another model
Thanks a lot for your detailed answer. I will have to wait to have the signal before being able to make some tests. I will inform you on to the details.
Best regards and thank you again.
