    It's theoretically possible to connect the 5530 to the NTU (bypassing the ONT entirely), but only if your ISP has made the necessary arrangements with open eir to make it possible. It's not something you can do yourself.

    Possible in the pure technical perspective (the art of the possible) - but not likely in practice.

    The fritzbox 5530 - while it can connect to a PON directly - it needs a specialised SFP to connect to the PON network directly.

    The service provider likely locks the PON down to known ONT serial numbers - so you cant just plug any old ONT into the network. They also may not allow non Huawei ONT's onto the PON - interop is not like DSL here, things are not automatically compatible and therefore locked down. (PON is not ethernet, the upstream transmission is tightly clocked between all ONT's on the PON (every ONT transmits when and only-when they are told they can - in their own non-overlapping window), non compatibility and incorrect timing can be detrimental for everyone on the PON).

    The ONT may also be doing traffic management (not just VLAN's, but QoS/Queue management etc...) depending on the network providers configuration. Third party devices can break this.

    The ONT will also support the performance monitoring features the network operator needs for service assurance (Packet counters, visibility of light levels) while providing a clear active demarcation point to whoever the retail service provider operator might be (assuming a SIRO situation for example).

    My advice: Consider the ONT as necessary infrastructure. Plug your Fritzbox in via the copper Gig port so you can manage the L3 aspects of the network yourself.

    This is very true, but open eir recently introduced an "NTU connection" version of FTTH, which allows service providers to submit PON-capable CPE for certification, and then to register their own ONTs - or CPEs with integrated ONTs, like AVM's PON SFPs - on the open eir network.

    I have no idea how many ISPs are providing the service. It seems like a lot of faff at the back end for questionable benefit.

    I would say , smart choice is to sign up with ISP which already supplying Fritzboxes as CPE and use existing Fritzbox 5530 as Access Point, part of a Mesh system.

    5530 only a basic unit performance wise same as 7530 , no point to bypass existing ONT for this sake.

    Thanks everyone…….the universe is telling me go with the tried and tested ethernet option!

    Definitely the easiest and cheapest option. No need to run fibre unless there are distances over 100m between the points or some electric/safety limitations. You won’t be needed Fritz 5530 for this anyway, just a couple media converters and tools for splicing/cutting fibre .

    Open Eir documents detail how they register a ONT to the network, so that would be a good place to start if you wanted to substitute your own.

    Just remember you need to use the correct SFP type.

    • GPON for rural fibre network (more than 2 years ago)
    • XGS-GPON for the newer urban installs (last two years)

    Interesting.


    Even for larger SMEs the motivations to remove the OE ONT are limited. BBU? Plug her in. Its not large/hot. The only real reason I could see is if a large customer had an outdoors solution they wanted to use, femtocells/monitoring points etc. where space could be premium.

    For all intents and purposes it's a media converter. There is nothing to optimise.

    ONT serial number is locked to a particular fibre port. So you can't swap them. Besides you'd need specialist cleaning tools.

    It's Huawei kit at both ends too. (so even if your kit worked it would flag the Chinese to start spying on you :pac:)
