Just wondering if anyone has attempted/succeeded terminating fibre (Auckland, Chorus) into own routers instead of provided ONT box?
My motivtion to go through this hassle is to declutter the cupboard space, reduce number of power points required and improve on cable management. At this stage I'm not sure if there's any performance benefit I could get out of using a somewhat spcialist router over what seems to be consumer grade hardware, but let's say that's also a driver.

 

Mikrotik routers for example have SFP-enabled routers, so it should be possible to physically plug the fibre into router. The bigger question is what sort of link that fibre actually is.

 

Any success stories out there?

No.

 

No.

 

 

Short form answer: NO!

 

 

The ONT is the demarcation point between the LFC and yourself. The LFC owns everything 'north' of the ONT, and it owns the ONT.

 

 

The ONT is 'dumb', in that it is a pure layer-2 device (we'll ignore the ATA ports and WiFI for the abominable aberrations that they are). GPON on the north interface, Ethernet on the south.

 

 

Then the RSP has their own demarcation device, the residential gateway (RG), that connects you to the Internet (or whatever service your ISP provides). Some RSPs will sell you the RG, or let you use your own. Others won't.

 

 

GPON is 'dumb', but it is in no way a simple point-to-point network. It uses Time Division Multiplexing (TDM to share between the other ONTs on the link See http://www.gpon.com/how-gpon-works.

 

 

Because security and privacy are important, and we don't want your neighbours snooping on you or interfering with your service (and vice versa), any sane LFC will have encryption enabled.

 

 

Your home-brew ONT is not going to get the AES encryption keys, Your home-brew ONT also won't have the appropriate code certificate and won't be trusted to be talked to at all.

 

 

And that's as it should be.
