Hi,
I want to get a Mikrotik router RB5009 and connect the SFP+ port into my 2Gb/s fiber connection.
I'm not certain which Mikrotik transceiver I need to order.
Requirements:
Can anyone guide me through this?

Depends if your ISP uses gpon or xgspon technology or it’s just straight ethernet over fiber.
For the latter, almost any SFP+ module would work, however, many ISPs uses GPON or XGSPON technology, where the terminal on your side (ONT) also authenticates with their terminal (OLT). For this you need a XGS/GPON SFP(+) module, that either your ISP authenticates on their OLT, or one that supports setting custom parameters (sfp.com has some) where you can clone the credentials from your original ont.
Do you know if your ISP is using a PON technology? What is the current equipment that the fiber plugs into (brand, model)?
Do you have 2Gb/s simmetric or assimetric speed (GPON is limited at 2.4Gb/s down and 1.25Gb/s up, while xgspon can do 10gb/s both directions)?
Of course the rate that you negotiate with the ISP (2 Gbit/s in this case) does not have to be the same as the physical rate of the fiber. The latter must be equal or higher.
2 Gbit/s fiber could be delivered over 10 Gbit/s XGSPON in many places.
The ISP provided a FritzBox 5590 (see here: FRITZ!Box 5590 Fiber | Fibre optic router)
I get 2000 up and down if that helps. I do not have an ONT. It has a username+pwd on VLAN35 via PPPoE.
They have an alternative with ONT. I wouldn’t need a transceiver in that case but would then need a router with 2 ports capable of 2.5GBs.
The FritzBoxes (Boxen?) are well-known for providing devices that have the ONT included. They often do have something that looks like an SFP, but it only actually functions together with the unit itself.
Many of these provide a "bridge mode" where they act as only an ONT, but this is model and provider specific. (Providers often get custom firmware that adds or removes functionality.)
Anyway, the rb5009 is well suited for these speeds. The usual setup involves connecting the 2.5GbE port to the ONT and then using either the 1GbE ports to further distribute connectivity, or adding a suitable switch connected through the SFP+ port. The CRS310-8G+2S+ is fairly popular for those who want multiple 2.5GbE ports...
The simmetric speed for 2Gbps excludes GPON.
That leaves only normal ethernet over fiber and XGSPON.
I see the fritzbox advertises as a router compatible with GPON and XGSPON networks, which makes me assume most likely it is xgspon.
Looks like there is a SFP module in the back of the router. Can you pull it out and look up the model? Most likely the SFP module itself is the XGSPON. There is a small chance the sfp+ xgspon module will directly work on a mikrotik router, but it is most likely that it won’t as the module will be configured together with the fritzbox and refuse communication with any other router. But hey, there’s a chance.
PPPoE does not exclude ONT. My ISP has the same deployment type, but they use GPON (gigabit connection) which I replaced with a configurable SFP onu (by cloning MAC, modem name/model, LOID password) and then I’ve set up the PPPoE client on my mikrotik router.
The module in a FritxBox is called FRITZ!SFP and it won't work on a RB5009:

I understand, but I’m trying to avoid using the 2.5GbE port for the WAN. The idea was to use the SFP+ port for the WAN and then use the 2.5GbE for the LAN. That’s why I was asking what would be the correct transceiver with a E2000 fiber lead.
I need to check with my ISP for GPON vs XGSPON compatibility.
Alternatively, I could go with a ONT and a different router (at least two 2.5GbE ports), which the RB5009 does not have.
Or get a SPF+ to RJ45 ethernet module and use that to connect to the FritzBox or other ONT
That’s the point of identifying what kind of connection you have, so we can suggest a proper module.
Personally, I have used the ont sfp from fs.com (this one: https://www.fs.com/eu-en/products/133619.html?now_cid=4895 ). The “with mac” version supports connecting via telnet (there is also a web ui version) and changing parameters of the module, like MAC address, brand, model name and the required credentials for the GPON connection, so the isp OLT thinks it communicates with the ONT provided by the ISP, not with a “cloned” module. You will also need to extract from somewhere (either the fritzbox or from local forums) what PON password your ISP uses.
However, since you most likely have xgspon, you will need a module like this: https://www.fs.com/eu-en/products/378841.html
There are also some on aliexpress, I’ve heard good of them from others, but I’ve personally never tried them.
I don’t think any configurable module with a E2000 connector exists, but you can use passive adapters from E2000 to sc apc or upc.
