You want your provider's box out of the meter cupboard and the fiber straight into the SFP port of your own router: UniFi, MikroTik, OPNsense or FRITZ!Box. Sometimes that takes one module and a patch cord, sometimes it can't be done. It depends on the technology at your address: AON, GPON or XGS-PON. This tool asks who your provider is and what you see in the meter cupboard. Then it tells you what you need and what to sort out with your provider.
Technology: XGS-PON (based on your meter cupboard)
Not confirmed yet: check with your provider
The technology decides what fits technically. Whether it's allowed and how to register it, we haven't been able to confirm for this provider. Ask your provider before you order anything.
What we don't sell
We don't sell GPON or XGS-PON sticks. Such a stick has to match the network and your provider, and your provider has to register it. Ask your provider which ONTs they support.
The same information as the tool, in one overview. For each provider you can see when we last checked it.

Every connection has its own fiber from the meter cupboard to the exchange. At your end the module transmits at 1310 nm and receives at 1490 nm: 1000BASE-BX-U. Because the line is yours alone, your provider doesn't need to register anything. This is where our BiDi module fits.
One fiber from the exchange is split across 32 or 64 addresses by a passive splitter. The wavelengths are the same as AON, but the protocol differs: the exchange has to recognise your ONT by its serial number. That's why you need a GPON ONT your provider allows.
The successor to GPON: 10 Gbit/s shared, upstream at 1270 nm and downstream at 1577 nm. KPN has only installed XGS-PON since mid-2021 and Delta since 2022, and 4 and 8 Gbit/s plans run on it. Here too: an ONT plus registration.
No need to unscrew anything. Look at what's there and what the labels say.
This is where the fiber enters your home. Passive: no power, no lights. According to the Dutch regulator ACM it's the network termination point; everything behind it is, in principle, your choice.
A box with a fiber cable from the FTU and a network port to your router, without a PON light. At KPN it often says Genexis. If this is what you see, you probably have AON.
A box with a PON light, or a label saying GPON, XGS-PON or ONT (for example Nokia, Genexis, ZTE or Zyxel). That means PON. Sometimes the ONT is built into the modem.
The FTU has an SC socket in two versions. Blue is SC/UPC, polished flat. Green is SC/APC, polished at an 8 degree angle. At KPN it can be either, per FTU; at Delta it's always green. Our BiDi module has an LC socket, so you need a patch cord from SC to LC with the right colour on the FTU side. BiDi only uses one fiber; with a duplex patch cord the second fiber stays unused.
Flat end face. Fits our duplex SC/UPC to LC/UPC patch cord; you use one of its two fibers.
View the patch cordAngled end face (8°). Needs an SC/APC to LC/UPC patch cord; get in touch for that one.
Get in touchNever mix them. A green plug in a blue socket, or the other way round, hits the end face wrong. You lose signal and can damage the connector in the FTU. And that FTU belongs to your provider.
Settings change and we don't track them per provider. Your provider's manual is what counts.
On AON, yes: a 1000BASE-BX-U module that transmits at 1310 nm and receives at 1490 nm, no registration needed. On XGS-PON you need an ONT that you register through the KPN service tool. On GPON KPN doesn't allow your own ONT; KPN moves you to XGS-PON free of charge.
If Odido delivers over the KPN network and your address has AON, yes: a BiDi module transmitting at 1310 nm. On Odido's own network (PON) you need an ONT that Odido registers through customer service. Odido's postcode check shows which network you're on.
Look in your meter cupboard. A separate box marked NT or media converter without a PON light points to AON. A PON light or GPON or XGS-PON on the label means PON. The installation date helps too: at KPN everything since mid-2021 is XGS-PON, at Delta everything since 2022. Want to be sure? Ask your provider.
In principle, yes. Since 28 January 2022 the Dutch regulator ACM treats the passive FTU as the network termination point. Everything behind it, such as ONT, modem and router, is your choice. On PON your provider may still require you to register your device, and if your own equipment causes problems your provider may offer less support.
An ONT stick has to match the network, the equipment in the exchange and your provider's registration. We can't guarantee that per address. We only sell what we can back up: the BiDi module for AON.
Always BX-U. It transmits at 1310 nm and receives at 1490 nm. The D module does the opposite and sits at the exchange. Two U's or two D's never give you link.
A single-mode patch cord from SC to LC. The SC end must match the colour of the socket in your FTU: blue is SC/UPC, green is SC/APC. The LC end is UPC. Blue is in the shop as a duplex patch cord: BiDi uses one of its two fibers, the other stays unused. For green, get in touch with us.
No. The BX-U20 also works on the short AON lines to the exchange. You don't need an attenuator for it.
