Hi Gnubyte, as may you already know, that SFP only has 1GE, so links for more than 1Gbps is not supported by the interface. apart of that think that you are using an SFP into an SFP+ port the auto-negotiation can fail by an issue in the router software (ROS), you can find many issues related with that on the forum and on the internet,
out of that, take in mind to than all devices of the link need to support and be configured to negotiate the full-duplex at 2.5G to the link be established successfully.
Thanks for your work on different GPON SFP modules.
I have a couple of MA5671A from Bell Canada. I can SSH into them at 192.168.1.10 but haven’t been able to find any useful commands that could be used inside the SSH session. Are they documented anywhere that you know of ?
ZISA OP151S
DFP-34G-2C2
DIPPER OPTICS D23446-SSHE
HUAWEI HG8010H (not SFP. Pure bridge device with one ETH port)
All of the tested resulted the same!
With all of these modules and HUAWEI device I can get O5 state for GPON and I can access the native VLAN on the ethernet which is dedicated for IPTV but no tagged traffic is coming out on the other side of the stick or LAN port of HG8010H. I tried to make a WAN interface on DFP-34G-2C2 with the same VLAN IDs and it could access it but making a pure bridge was never successful. This made me believe that there is some QinQ with the default VLAN ID so it works as a WAN interface on DFP-34G-2C2 or HUAWEI HG8245H but does not work if I try to access VLANs via mikrotik or any other managed network device. Other users experienced the same.
OR… Alll the above mentioned modules does not work in transparent mode.
Therefore, I believe, not even CarlitoxxPro latest stick will work if I don’t find out what is the problem with these.
Can anyone help me out with this? I believe this may help others too.
out of that, take in mind to than all devices of the link need to support and be configured to negotiate the full-duplex at 2.5G to the link be established successfully.
Pretty much the same here. I have talked quite some times to O2 but still they cannot figure out who should I be talking to. It is being escalated internally, but does not look good…
I am also talking to CarlitoXXPro because my GPON is always in O5 state, regardless of the PLOAM that I configure. I have confirmed with the O2 technician that the PLOAM I have is the correct one, but if I set a fake one, the GPON shows O5 anyway, so I am also wondering if the GPON is defective. No luck so far.
Maybe I can help. I have the DFP-34X-2C2 (which is the same as DFP-34G-2C2 but supports both EPON and GPON). You should NOT create WAN connection. If you do it the SFP will act as a router. You should leave it without WAN connection to get bridge access and pass all VLANs to the attached device.
In my case my ISP provider offers internet in VLAN20, so I have to make sure that the SFP port accepts traffic from VLAN20 (virtual interface vlan 20?).
Do you have to put VLAN information in ‘Application —> Multicast —> VLAN Configuration’ section? I have the exact same GPON stick but cannot connect to the Internet via PPPoE at all.
Hi, Many thanks for reply! I did everything like it should be. I have no WAN connections on the stick itself. However, if I try to add WAN connections then I am able to open all VLANs on the stick itself but when all WANs are removed, I am not able (mikrotik doesn’t detect any VLAN tags) to access VLANs. It seems like it doesn’t work as a bridge. Native (untagged traffic dedicated for IPTV) VLAN is available but no tagged traffic. If You know what to do, I will give You access to my PC and will pay You for a successful setup.
Ok, so all I have to do is to put the OLT password in the SFP, and then put a VLAN interface on the SFP socket in routerOS, then run a PPPoE dialer on that VLAN interface?
IGMP snooping has to be enabled on the GPON stick?
I am willing to pay for a successful setup for at least one of these devices:
DFP-34G-2C2
DIPPER OPTICS D23446-SSHE
HUAWEI HG8010H (not SFP. Pure bridge device with one ETH port)
I need VLANs available in mikrotik. I know VLAN IDs, except DPOptics, other two can successfully register to OLT. With DPOptics I never achieved a successful registration to OLT.
Hi, I bought the module “CarlitoxxPro GPON ONU SFP (CPGOS03-0490 v2.0)”, I want to share some of my conclusions after doing many tests.
It is not 100% compatible with all Mikrotik routers, as comrade Gnubyte commented, the module is not always detected by the router, you have to remove and reconnect the module several times until it works.
The SFP module does not have a link until the fiber cable is connected, therefore it is not possible to configure it or check the status if the optical fiber fails, for example due to a damaged cable.
The module status screen always indicates O5, it never changes.
Needs to takes a long time to sync and connect with the OLT.
Sometimes the module crashes, link is UP but not responding.
It is not possible to do Port Forwarding, nor have I been able to receive RIP routing, I would say that the bridge does not work well.
It is not an easy task, but once connected and synchronized with the OLT, all the VLANs work and the transfer speed is correct.
In my opinion it does not work 100% well, I would not install it in a production environment, at the moment it is only valid for tests or as a paperweight.
If anyone is interested in buying this module, mine is for sale, contact me, we can surely reach an agreement.
You reported a lot of bugs for it. However, port forwarding should not be done on the module itself. This module should work as a pure bridge. For me will be enough if it works stable inside of the media converter cage. Send me Your offer in pm including shipping costs to Montenegro and a payment method.
By the way… Have You ever had a module which worked for You? Which one was it and how did You configure it? I offered to pay to the one who can make a working configuration with certain modules mentioned in this thread but nobody answered. It seems that nobody ever made it work or nobody wants money.
Actually as the ONU SFP acts as bridge you should think of it as a TRUNK. All VLANs passthrough it to the ‘next stage’, in this case the router, so you should have one virtual interface per vlan.
I’m sorry but I’m no mikrotik expert, I’m unable to help yuo with the exact needed steps.
We have a few questions about all the issues that you are describing here:
1- Did you tested the GPON ONU SFP into a media converter (E.g: TPLINK MC220L) to discard that you have issues with your hardware(router) or with your unit(SFP)?, did you measure the voltages delivered to the SFP are inside recommended values? the issues reported by Gnubyte is related to well-known issues between SFP devices into SFP+ ports (also mentioned by Mikrotik). Related the SFP details displayed in winbox, that is related to http://forum.mikrotik.com/t/request-support-i2c-sfp-sfp-secuential-singlebyte-reads-to-obtain-transceiver-details-from-eeprom/142454/1 (Again is not a SFP issue, is related to how was made the firmware of the router and how it reads the eeprom values)
2- Depend on the router model/brand the FO could be required to be connected to the router and be detected the link to make it possible to access to the SFP Web/Telnet. That is entirely dependent on how was designed the firmware of the router, not the SFP itself.
3- Witch OLT brand/model you are trying to connect?, if you have the SFP ONU connected to your router (at least 1 minute too boot the embedded OS) and after, you connect the FO to the SFP, the authentication time with the OLT should be in less than a few seconds. Can you explain detailed the steps that you follow?
4- In what scenario the SFP Crashes? What temperature, BIAS voltage have? with/whit out FO connected? can be more explicit with that.
5- The SFP works like a traditional ONT, is a fully bridge device L2. if you don’t receive some specific traffic like IGMP for IPTV, did you check if all tripleplay services was correctly/fully provisioned from the OLT? That could be a bad provisioned profile from OLT, did you have more details from your ISP support team?
Please don’t hesitate to contact us and provide all the details of your test and the information that you receive from your ISP, to diagnose better your issues.
