Topic: GPON and Mikrotik
This topic is intended to be a discussion about using Mikrotik routers/switches in a GPON fiber connected network.
Use case; Where an ISP utilizes a GPON fiber-to-the-home optical network , and the customer/client end of the fiber network is a Mikrotik device that connects directly to the GPON fiber using a SFP port on a Mikrotik. ( Note - as of this date - Mikrotik does not manufacture routers or switches with built-in GPON. )
*** However - now discontinued , Mikrotik did have a GPON SFP product called “GPON ONU module” which their web page identified it as “Pluggable GPON ONU interface for Fiber to Home” -and- the physical SFP module had the marking on it * Mikrotik FOXCONN S-GPON-ONU *
I want to discuss what SFP products ISP’s are now using to connect their Mikrotik products to a GPON network ( what works and what to avoid ).
I would like to use a format similar to the following:
Manufacturer
Product-Part-Number
Product name
Notes
mfg: Mikrotik
part#: SFPONU
name: GPON ONU module
notes: Discontinued - I experienced thermal problems when located in outdoor enclosures
notes: All of my Mikrotik SFP GPON modules ( 20 plus ) bricked on the first hot summer day ( and could not be recovered )
mfg: FS
part#: GPON-ONU-34-20BI
name: GPON ONU Stick with MAC SFP 1310nm-TX/1490nm-RX 1.244G-TX/2.488G-RX Class B+ 20km DOM Simplex SC/APC SMF Optical Transceiver Module (Industrial).
notes: Shipping - I have tested these indoors and they work
notes: Head-end ( OLT ): Adtran TA 5000
notes: Client ( ONU ): Mikrotik RB962UiGS-5HacT2HnT ROS-Version: 7.18.2
notes: I have not yet tested in outdoor enclosure on a warm/hot summer day
notes: US $65.00 , about 4.7K Sold
notes: I configured a DHCP-client on the SFP interface and the Mikrotik came up ( also put the Serial # in the OLT )
Please post what you are using and your comments ( indoor use or outdoor enclosure use )
FYI:
- At my ISP , I am trying to keep my customer ONU’s as a Mikrotik with a GPON SFP module installed.
- I have used many other all-in-one GPON ONU’s ( with Residential-Gateway NAT ) - but I prefer to try to stick with Mikrotik if/when possible.
- By using Mikrotik ROS ( with a GPON SFP ) , I can do advanced routing/bridging-switching/L2 & L3/NAT/FireWalls … ( unlike all-in-one generic GPON-ONU’s )
- My wish-list , a Mikrotik GPON ONU / ONT that runs ROS.

FYI - Here is a basic GPON network design.
- Each GPON fiber network ( PON ) uses a single strand of fiber to the optical splitter
- Customers can be 20-km in distance
- An optical splitter does not require power
- Optical splitters can be 1-in-and-8-out or 1-in-and-16-out or 1-in-and-32-out or 1-in-and-64-out
- Optical splitters can be located in the ISP’s NOC -or- located miles away in a high-density customer neighborhood.
- Each PON can support about 2.4-Gig download to customers ( total PON to all customers on that PON )
- Each PON can support about 1.2-Gig upload from customers ( total PON from customers on that PON )
- Per PON , it is possible to have 20 customers with sustained 100-Meg-download and 50-Meg sustained upload rates ( all at the same time ) ( I have some customers with 1-Gig up and 1-Gig down rates ) - and still have reserve capacity for more customer bandwidth demands
- *** There are also faster types of GPON devices which operate at about 10-Gig per PON network. * qty-10 10-Gig PONs is a heck of a lot of bandwidth !!!
- Unlike wireless WISPs ( wireless to the home ), GPON is 100-percent immune from rogue WISPs APs and customer wireless router interference
- At my ISP , I operate about 80+ PONs.
- FYI , I started out as a WISP using Mikrotik for APs and Clients. The wireless could not reliably handle the bandwidth to hundreds/thousands of customers , hence the reason I am now also using GPON.
I’m using one DFP-34X-2C2, connected to an RB5009.

I’m just an ISP client, but I know they use this module to some corporate clients, that want to just plug it in some SFP+ port and go from there. My connection is just 500 Mbps, so I can’t say what it would do with a heavier load. At this speed, it works flawlessly.
It synced at 2,5Gbps on the SFP+ side, but only after I disabled auto negotiation and set it manually.
From the web interface of the device itself:
Device Name DFP-34X-2C2
Vendor ID ODI
Uptime 55 days, 3:33
Firmware Version V1.1.6-240202
Hardware Version V2.0
CPU Usage 0%
Memory Usage 51%
Temperature 54.558594 C
Voltage 3.240500 V
Tx Power 2.560445 dBm
Rx Power -19.317674 dBm
Bias Current 13.000000 mA
The ambient temperature must be about 30 C.
My RB5009 is on the wall, cables going down and radiator up. It’s reading 52 C.
Hello, I'm kind of new into this world of using sfp onu stick to bypass the ISP ONT.
I bought the HSGQ Xpon Stick ONU 1.25G/2.5G SFP Pon Stick With MAC PPPoE IPoE HGU SC Connector 1310/1490nm 20KM OLT ONU MAC XPON=EPON/GPON from aliexpress and when I insert it into the SFP port in my router, the lights from the linking interfaces turns off and the router disconnects from winbox. (It also happens when I unplug the stick from the port).
The sfp light doesn’t turn on, and into the winbox area, the interface never runs.
Can someone helps me with the problem and maybe give advice of what I'm doing wrong.
Btw, my router board is a hEX S RB760iGS.
Did you try to plug the stick to the router, and the optical connector to the stick too. Then unplug the power supply (so that the router is fully shutdown). The re-plug the power supply and wait for both the router and the stick to fully boot up?
I did try shutting down the router and with the stick fully plugged in connect the power supply and wait for it to boot up completely, but it failed again. I tried that twice. With the fiber cable connected I only tried once but with the router fully on, I didn’t try to disconnect it from the power
