[Discuss for BPI-R4] Batch production version: 2x10G SFP or 1x10G SFP + 1x 2.5G ethreal port?

[phuongnam (Phương Nam)]

I vote 2x10Gb SFP, Can 10Gb Wan SFP port be used with 2.5Gb Gpon SFP module and used PPPoE on openwrt connect to ISP?

should work, but gpon-modules need a bit more work to get working (sfp quirks + temporary change LOS-gpio to get on webinterface without link). and SFP must not exceed 3W

You can put 2.5gbps sfp in the 10g sfp+ slots and they work. I don’t think poe works via sfp+ slots. The general sfp/sfp+ support in the linux mainline kernel is a bit hit and miss, but that will improve over time. Particularly as 10g ethernet and fibre cabling it becoming more affordable in the home. Fibre also uses a lot less power than rf45 cat5/6 cables. I vote for dual sfp+ slots. I don’t need poe as I have power sockets everywhere I might need an AP. I only use poe for more remote things like cctv cameras, and they get power from cots poe switches. So I would say poe is rarely needed in people’s homes. I would like to see a usb socket that embeds the USB to console uart feature inside the case, instead of needing dongles for console access.

I plan to use this router for a long time without having to upgrade. My goal with the diagram is as follows, so I need to refer to it carefully to avoid waste. Other features of the router I will review later. Thank you for all your advice

[Thanks]

Here I mention some 2.5G xPON ONU SFP Sticks:

[BPI-R4] and SFP

I think these 2.5G xPON ONU SFP Sticks work on the BPI-R3 and BPI-R4, because here on the forum, on reddit, on Ubiquiti, Turris and MikroTik forums have reported that they work (on other hardware but I think they are based on Linux). Chipset: Lantiq PE98035 Huawei MA5671A (Recommended) Nokia G-010S-P FS GPON-ONU-34-20BI The “Nokia G-010S-A” has pin 6 hardware issue. The “FS” GPON has disconnection issues on Ubiquiti hardware. It can be configured more or less via the web interface and requir…

As AP you can buy OpenWrt One, it can be powered via PoE, here is more information about OpenWrt One:

ohh, the videos you attached in the article are youtubers in my country, it should work, but in other places I don’t know if it will work or not. in case sfp doesn’t work, i think to use available ethenet WAN port (sfp + converter)
