Regarding the first question (What's the difference between a router/switch and ont?): They are 3 distinct things. A router serves as a gateway between your public internet address and the devices in your local network, doing what is called Network Address Translation (NAT). A switch does not do that, neither does an ONT (unless it is a combined ONT/router unit, which is the piece of equipment that ISPs usually install in the client's home). An ONT serves as a converter between optical fiber and copper cables and handles the authentication with a fiber ISP's OLT. A switch serves to connect multiple devices within a local network. Regarding the second question (Are those limited to gpon sfp module?): ONTs are not limited to SFP modules. There are also ONTs with ethernet connection instead of SFP, which can be used to connect to a router's ethernet WAN port. Regading the third question (can we make any switch a gpon ont by insert an compatible gpon sfp into it?): In this case, the ONT is actually the GPON SFP module, not the router or switch . But you could attach a GPON SFP module to a switch to convert from SFP to ethernet and then connect another port of the switch to a WAN port of a router. In this case, the switch would not be behaving as a switch, but rather as as media converter (which is another piece of equipment you can buy to connect the SFP module). But in any case you would still need a router to do the network address translation. Regarding the fourth question: "Last, are gpon ont sfp and gpon onu spf the same or there's difference?": There's technically a difference between an ONU and an ONT, but these terms are usually used interchangeably. The expressions "GPON ONT SFP" and "GPON ONU SFP" refer to the same thing. But, in this case, technically, we're actually talking about an ONT, not an ONU.

@@vitorao Thanks for taking time to write really detailed answer. It really cleared my doubt. I have another one, for user management, what's the difference between a gpon ont and ethernet switch that's using gpon sfp module? Are they both using Vlan to separate the traffic or there's some difference in their working.

@@RahulAhire, it's pretty unusual to have a switch with a GPON SFP module. Those modules are usually intended for being used directly in a router with an SFP port. Regarding the difference between using a GPON SFP module and an ONT with ethernet connection, they are usually intended for different use scenarios. A simple ONT with ethernet connection is a cheaper solution designed to work with simple routers that only have ethernet connection, and that will work fine for most users. SFP GPON modules, on the other hand, are usually intended for corporate networks that use high-end routers and require an internet connection faster than 1 gigabit/s, as most ethernet connections won't support speeds higher than that. Also, attaching a SFP module directly into a router saves space (which can be a very important thing in corporate racks with tons of equipment) in comparison to using a separate ONT.

@@RahulAhire, regarding the VLAN question, there will not be much difference between a GPON SFP module and an ONT. Both will usually have 2 options. One is called "transparent mode", which will allow the traffic from all VLANs to be directed to the router, and then you will need to configure what to do with each specific VLAN on the router. The other option it to tag a specific VLAN, which will allow only traffic from a specific VLAN, and then you do not need to do any VLAN configuration on the router. The latter is usually done when you need only one VLAN to go into the router and you have an old router that does not support VLAN management.

@@vitorao thanks for answering it, highly appreciated 👍🏻

Hi, you don't need the PoE switch to power on the SFP module. Any router or switch with SFP cage (port) will do.

@@VanTechCorner that's what I need. I have 3 PoE APs (UAP AC PRO) and have no SFP port. So I need to power the APs but need SFP too

Since you are using UniFi/Ubiquiti products, you can take a look at the UniFi Switch 8 PoE (150W) or the EdgeSwitch 8 150W. They are quite expensive IMO. I will grab a 5 ports PoE switch, such as the Netgear GS305P or TP-Link TL-SG1005P and a media converter for the SFP module.

Cool, please share the model of the SFP module and the ISP too. I believe it will be useful for others.

e ai, fez o teste? qual gpon stick vc usou?

@@sbromulo Ainda não, entrega atrasada.

@@geraldoteodoro9326 blz quando fizer os testes me avisa aqui. Vlw

@@sbromulo Sim, pode deixar que aviso sim. Ansioso aqui pois estava previso para chegar dia 8. :D

Hello, may I know the model or brand you are talking about. Please don’t put links because KZfaq will think it is spam and remove the comment.

Available in india?

Hey, you can take a look at the Nokia G-010S-A or the Huawei MA5671a. For the G-010S-A, you can see my recent video for more info kzfaq.info/get/bejne/ac1moLV1y7vUoIU.html

Thank you. There is the EP.2 with the NOKIA GPON SFP G-010S-A, you can check it out at kzfaq.info/get/bejne/ac1moLV1y7vUoIU.html

@@VanTechCorner I already watch it. 😂. It’s very fun to do this hackery.

Basically after you configure the SFP Module (with a Media Converter / x86 OpenWRT Router PC with SFP port, etc) the SFP module will become the ONU/ONT and you can plug it to any system (EdgeRouter Pro / UDM, etc). You can also configure the SFP GPON module with the UDM as well (by create a bridge and assign an IP address, I done this with EdgeRouter, not sure about UDM).

It should be as the SFP GPON module is just a the same with a normal SFP transceiver (module). Unfortunately I don’t have the device to test.

Sorry I don't get what you mean. Is this the 2nd part of the question?

Hi, there is no information about this, but the Huawei MA5671A and the Nokia G-010S-A can be flashed with OpenWRT (old release). On my next video, I will talk about the Nokia G-010S-A GPON SFP.

Hello, do you know the full name/model of the ONT and what is your ISP?

Hello, from what I know this module is to insert to the OLT (from the ISP side). It won't work as ONU/ONT (client side).

Hi, for XGSPON, I have no idea. But if you are looking for XPON, I have some suggestion: - kzfaq.info/get/bejne/q8yqhZuWmdPZkps.htmlsi=NJnJ3o_lh53WrrmE - kzfaq.info/get/bejne/fZmmlJqJmba-dqM.htmlsi=NnjtcjNvlSG11VqB

Hi, the answer is no. You need to understand what is the OLT and find a suitable SFP GPON module ( that can communicate with the OLT)

@@VanTechCorner Doesn't GPON just use PPPoE?

@@VanTechCorner how do we find the olt?

@@chaoscapricorn13 communicate with the staff of the NOC.

Sorry for the late response. This is the module that I used, but please take not that it will not work with all type of GPON SFP module kzfaq.info/get/bejne/bNmWppml26rPl2g.html

Hi, from what I know this product is already EOL so there is no new product available. I can see some new PON sticks available in the market, such as the "GPON/EPON/XPON ONU Stick" sold by ODI, or the Nokia G-010S-A and the Huawei MA5671a ...You can take a look at them (the Huawei MA5671a has an active thread on the OpenWRT forum)

EdgeRouter X SFP, Mikrotik Hex S, RB2011, RB3011, RB4011 rất nhiều lựa chọn nhé bạn.

Hi, there is pros and cons of doing this and we have another comment discuss this. If you have no issue using the ONT from the ISP, there is no need to replace it. Along the way, when you slowly upgrading your network rack and want to reduce the number of devices to build a nice rack, perhaps you will need one

Hi, may I know the country? Do you mean Active Optical Network (AON). If yes, here is the comparison done by FS community.fs.com/blog/pon-vs-aon-in-ftth-systems.html

South Africa (ZA) - ours was ducted underground but other providers string the cable along existing street poles, and they use GPON. Also we just get internet - no TV or VOIP services.

Hi, I have no chance working with ACS so I can be sure it will work. However, I believe it is something configured on the router side, not the Fiber/GPON. First, you will need to understand your ONU and OTL before we can move on.

Khi bạn tự trang bị SFP GPON hoặc ONT, bạn không cần họ cấu hình bridge mode vì lúc này bạn không dùng ONT (thường là ZTE hoặc Dasan). Bạn sẽ cần tài khoản để tạo kết nối PPPoE và thông tin này về nguyên tắc trên hợp đồng Viettel phải bàn giao cho bạn. Bạn nhờ kỹ thuật hoặc tổng đài cung cấp.

@@VanTechCorner thank bạn !

Hi, it means VLAN 35 on eth0 interface. My ISP runs PPPoE on VLAN 35 and I have to configure the same in order to establish the connection.

Hi, landline has a different cable and ONT/ONU. I have yet to play with it, therefore, I can't provide more info.

It's optical, it probably does, you just need to know the specifics of the service (service provider nuances).

@@jamess1787 It does not unfortunately because the authentication AT&T uses for their FTTH network. I tried cloning the MAC but the Certificate used is hard to extract from their equipment.

ISPs in the US could probably get away with literal murder based on the way they're allowed to bribe representatives to sign agreements to disallow competitors to come in. Comcast is getting really bad lately. Last year I had to sign another contract with Comcast to keep my price down. Their discounted plans all had a "you have to use our modem" stipulation. If I wanted to keep the modem I bought, I'd have had to pay something like $200 MORE per month. In my area I don't even think I can get DSL. It's Comcast or whatever WISPs exist here.

Hi, the Hisense LT33415 is dis-continued but you can find the NOKIA GPON SFP G-010S-A, here is an update video about it kzfaq.info/get/bejne/ac1moLV1y7vUoIU.html

Yes, compatible with Mikrotik 4011

@@vuducdong, thank you. I've just tested it with Mikrotik 4011 and indeed it works great.

I have yet to use it so no clear information on this. However, I can see that XGS-PON use a different wavelength compare to the GPON, this is something you need to pay attention to when looking for a compatible XGS-PON SFP model/ONU. For the authentication I believe it will be more or less the same...

​@@VanTechCorner thank you. and great channel you have very informative and love you videos showcasing openwrt and the latest embedded devices,

@@b4kk4li did you found a solution for xgs-pon?

A little space is saved, and that's it.

No backdoor on the ONT device?

@@somebody301 What can a backdoor do when it is on a separate network, protected by your router/firewall? It is located at your home doesn't mean it can do anything -- it is basically like a malicious device on the Internet.

You will have more control of the devices and more statistic of the “ONT/PON Stick”. Save space, save power and you don’t need a power adapter for the ONU … Less cables, simple setup …These are thing I can think of. There is no clear evidence but the PON stick will also increase the connection stability (both Fiber and Ethernet). I have the PPPoE connection up and running for more than 3 months with no down time.

Hi, I foud the D-Link DIR-842 C2 when I was working in Malaysia. This device was provided to the customer for free if they sign up for Internet plan from Unifi (TM). That is why the router is sold very cheap secon hand. If you plan to buy a router, I suggesg the Xiaomi Router 4, or the Xiaomi R3G for better support and WiFi coverage.

@@VanTechCorner thank you very much but their routers no comptible with oprntwrt I use it as access point so i want you to advice me to choose one wich has port usb to extend the memory and install more application and i want it has dual bands 2.4 and 5ghz and be easy to install openwrt without problem or with usb TTL thank you agin

Hi, sorry for the late response. From what I know, if the ONT is ZTE, most likely the OLT will be either ALU or ZTE. In this case, you can try the Nokia G-010S-A which I already made the video. This GPON SFP module should be available on Taobao, AliExpress and other marketplaces.

@@VanTechCorner thanks for replay

Không em ơi, nhưng ODI về cơ bản hầu như chạy tốt với các nhà mạng ở Việt Nam. Chỉ cần clone đầy đủ các thông tin nó sẽ chạy.

Đúng rồi bạn, mình có ghi trong mục about là kênh từ Vietnam mà.

No

Hi, you can take a look at the Nokia G-010S-A which is widely available kzfaq.info/get/bejne/ac1moLV1y7vUoIU.html or the ODI GPON SFP module.
