Edit: disregard my comment, I mistook PTP to mean Ethernet while in reality it's Point to point Fiber. In any case my point about noise still stands. But PTP Fiber is really rare in the world, given how many people are stuck on coax.
Yes, with FTTH (or FTTP) I meant GPON. Refarding PTP, do you mean a residential ethernet network? (Technically FTTB, copper / ethernet to the premises)
Branding anything other than FTTH as "Fiber" is misleading.
It's like saying DOCSIS 3.0 is Fiber because its a Hybrid Fiber-Coaxial network, while in reality all cable internet networks are HFC, the difference is the number of nodes serviced by a CMTS, which when reduced by a node split will result in higher speeds and more capacity.
Or saying DSL is "Fiber" because uplink to the DSLAM is Fiber. All DSLAM uplinks are Fiber, difference is how many street cabinets are there because DSL speed is dictated by the local loop length, and with more street cabinets there is higher chance one gets built closer to you enabling you faster speeds.
I meant a residential fiber network, where the fiber really goes into the home, and the topology of that network is point-to-point. As in from some POP(point-of-presence) from ISP into the home, not over shared channels like in GPON.
My ISP is rolling that out, though with delays. They are a spin-off of a public utility.
and in the user-forum of that ISP there are people describing how to directly interface to fiber with a pre-fabricated cable and SFP-transceiver with the right wavelengths, from a self-owned router with SFP-cage.
But you still have to connect over PPPoE with a MTU of 1492 bytes. Multiple times actually, on different VLANs for
management, VoIP, and public dynamic IPv4(CGNAT)/IPv6(native/64)
RE: PPPoE - in general most AAA systems already work with PPP and since ISPs generally have to support legacy infrastructure too, and multiple access technologies, they "force" all users to connect with PPPoE for billing and data collection for identification.
For example, a national ISP in my country uses PPP for xDSL (which is a dedicated medium) and GPON (which is a shared medium, however the authorization and speed limiting is done by the ONT S/N), none of which "need it". You can also mix GPON and DSL logins and it will work, even between users.
The only logical reason for this, from what I can see, is that they are forced to sell access to their infrastructure (being an ILEC) to other ISPs, so they use PPP to route traffic from users of other ISPs from the BRAS to the corresponding network gateway using a MPLS tunnel.
For business fiber, not based on xPON, there is no requirement for a PPP session, and instead you get assigned an IP address range that you router should use, and the fiber is connected with a SFP+ module to your router. On the ISP's side, your "port" is limited to accessing their intranet for management and remote control, and your assigned IP address range.
