Hello.

Our WISP is now moving to work with optical fiber and recently we bought a SFP GPON mikrotik brand module.

We put it to work with a RB and connected the fiber with our OLT.

The status of mikrotik RB interface changed to "registered" but the serial number of sfp didn't appeared in OLT blacklist or other place.

I searched on the Internet but found almost nothing on this subject.

We would be pleased if someone can clarify for me how to put it to work or give me some steps towards some solution.

Thanks in advance.

What OLT are you using? In all I've seen you need to add ONT to OLT.

Agree with locodog, what kind of OLT do you use? There are two GPON optical transceivers https://www.fs.com/c/pon-transceivers-2845 that you can look into.

If you are considering using the Mikrotik GPON module in a production environment , perform some extended acceptance testing first.

I had about a dozen test outdoor installs with Mikrotik routerboards and the Mikrotik GPON Module. They worked OK during the winter. However when summer hit and the temperatures started warming up, I experienced a 100 percent Mikrotik GPON Module failure all within 2 months.

---> I experienced a 100 percent Mikrotik GPON Module failure <---

I was planning on possibly using thousands of them , not anymore.
The Mikrotik GPON Module already runs hot. Now put that in a standard outdoor case on the side of a house in the summer and it cooks itself to death. When it dies from heat, it is bricked.

I would guess that none of the Mikrotik GPON Modules are burn-in tested & certified for use in the typical outdoor GPON environment.

O well or is it O hell , 12+ Mikrotik GPON Modules crapped out due to normal summer temperatures.

Hello.

We use a FiberLink OLT. Normally with FiberLink OLT and FiberLink ONT(or ONU) the serial number appears in the blacklist just in time that PON link is stabilished. Then we have to add that in whitelist and provide an IP number, After that a script runs and do the rest of configuration.

We have a mikrotik ONU SFP module and we did tests pluging it in a RB mikrotik (SFP ONU mikrotik with RB mikrotik).

What happens is: when I plug the fiber cable in mikrotik module the sfp interface show "R" on winbox (registered, the same status when a ether port turns connected) but the module serial number didn't appear in blacklist and I'm not able to find this serial in another place.

How was your scenario?. You used mikrotik as OLT or as ONU/ONT? We bought an "mikrotik GPON ONU module" to put in client house instead the ONU we use today.

From what I understand; The only Mikrotik GPON device available from Mikrotik is the Mikrotik GPON ONU module. Re their documentation "...The product provides a pluggable GPON ONU interface..." means the Mikrotik GPON SFP device can only be used as a client device. (I wish Mikrotik had GPON SFP modules for both sided of a GPON fiber network).

Re the Mikrotik GPON SFP module registering itself on the network, ... I use Adtran TA-5000 head-ends. When connect up a (client) Mikrotik GPON SFP module on the GPON network, my Adtran-TA5000 units do immediately see the remote Mikrotik GPON Module.

At this time, I have only one remaining operational Mikrotik GPON module. It is located in an air-conditioned server room. All other Mikrotik GPON modules in my GPON network are located in outdoor nema enclosures. They all died in the early summer when it started to warm up.

When the Mikrotik client GPON is connected, my Adtran does see it:
!
remote-device ont 6@1/20/1.gpon
description "Mikrotik--6@1/20/1--MKTK0c150972"
mac-spoofing-allowed enable

!


When I show more detailed information about this GPON connection, this is what I see:

I remember it took me a month or more just to figure out how to get the Mikrotik GPON module talking (due to a lack of Mikrotik documentation on how to use/configure it).

As far as the Mikrotik side, you just treat it like any other interface - no special configuration.
As far as the up-stream head-end device, that is what you need to play with (bridge - nonbridged - Ethernet - virtual Ethernet - mode access or vlans ...) good luck

Hi Tom,

I am experiencing as well a very high temperature of the SFPONU module from Mikrotik. What you have written here is worrying me much.
Have you checked maybe if other SFP modules from other manufacturers are heating up as well on Mikrotik hardware? Is this a flaw of the module itself?

I gave up after trying a dozen Mikrotik GPON SFP modules. ALL of them (except one) turned into bricks. Other than the one remaining working one, all of them were installed during the early winter in outdoor nema enclosures. They worked great - untill the first part of summer when it started warming up. They all pretty much died within the same mid-early-summer 1st month of warm/hotter tempretures. The single Mikrotik GPON SFP module that is still working is located in my air-conditioned server room. In text chatting with Mikrotik, the issue was supposed to of been resolved in the newer/later Mikrotik GPON SFP modules that were shipping. I have not ordered any another Mikrotik GPON SFP modules after the huge failures they all (but the one) encountered. I felt that continued testing this Mikrotik product was like buring money (literally !!!).

I have only done some minor reading research into other GPON SFP modules. I have found nothing to support other brands might have overheating/bricking problems simular to what my Mikrotik GPON SFP modules experienced. I am somewhat game and open to the idea of testing the Finisar GPON SFP modules. However for me to even consider Mikrotik GPON SFP modules again, I would want them to ship me ( for free ) a dozen GPON SFP modules and then give me 1 to 3 months to test/verify they will keep working during the hottest days of the Summer (testing indoors or during non-summer not-hottest-days-of-the-year periods is just a bad idea).

This IS a serious flaw of the Mikrotik GPON SFP module itelf. When it bricks (because it got hot), this Mikrotik product is not recoverable.

Recently, I started looking for / searching for a passive SFP 1 to 2 inch long extension device which functions as a heat sink for warm running SFP devices. But there is a potential problem still in that after a heat sink gets as hot as the SFP device , then it is actually would no longer provide any cooling properties (especially when installed in an outdoor nema encolsure.

I feel this is/was a 100 percent Mikrotik quality control problem. In the early days of the Mikrotik GPON SFP module product release, ALL of them should of been tested in the same thermal enviornments that every GPON device allready experiences , -20 to -30 F below freezing and 120+ degree tempretures with no colling in an enclused nema enclosure under full running/active network testing , and for a period of at least 7-days to a month of continues tempreture cycles. This should be normal Q/A testing procedures for any new network product. If mine had been tested , then they would of burned out at Mikrotik's tesing facilities and then Mikrotik would of discovered there are serious faulty problems problems which turns the product into a brick !

EDIT: All GPON devices should meet normal industry temperature-hardened operating conditions of -40 to 85°C (-40 to 184 F). Clearly , the product I tested did not even come anywhere close to that prior to 100 percent failure !
((( FYI - The Mikrotik brocure-specifications state: Operating case temperature: 0~70°C . ))) --- You might need an air conditioner to keep it working - lol

Anyways , ulysses - I hope this helps and supports any decisions you make re GPON. If you find any working GPON solution that works with a Mikrotik , please let me know - thank you .

Same problem again here. As soon as temperature increases, transceivers goes down. What a pity. It would be a good option playing with MKT Powerbox to provide POE solutions over a GPON Networks. Other product that I can't buy to Mikrotik.

I've rarely been totally disappointed or burned by any networking products during the last 40-years of my networking experience.
However - - - The worst device I've encountered is the Mikrotik SFP GPON module :( :( :( :( :(
They work great in the LAB. They appear to be just what you need for your customer GPON network. Good price also.
The problem is, 100 percent of ALL of them will die and turn into a SFP brick the first time it starts to warm up at all of your customer locations when warmer temps start at the end of Spring or beginning of Summer.
The only way to not brick a Mikrotik SFP GPON module is to install them in an air-conditioned out-door enclosure or next to a 5-thousand CFM fan.
Out of all the Mikrotik SFP GPON modules I installed, all of them except for one of them died the first few days of Summer. The single remaining Mikrotik SFP GPON module I have that still works after all these years is installed in my air-conditioned NOC and the room temperature is kept at 67 degrees.

In my opinion, this is a very bad unreliable networking product that the manufacturer refuses to do anything to fix the problem or even offer any support to ISPs who have had this horrible experience with their products.

Please don't get me wrong. In my opinion, Mikrotik products are all great and work well - - - except to this one product !!!

It can be the reason why it's now discontinued. Too bad, GPON seems popular and I'm sure people would much rather have something well supported from MikroTik than go for Chinese adventures like in this thread. I know I would.
