What SFP modules?Hi all
I need recomendation, for sfp gpon onu RB 4011.
I was try 2 moduls sfp but not work.
Thanks.
On Mikrotik page about the 4011:
Note: The RB4011 does not support Passive DAC modules and SFP GPON modules
It all depends on the SYNC rate used by the PON provider and whether the PON Provider will accept PON transceivers from parties that they have no affiliation with. So your comment is a little misleading. The OP MUST find out which GPON MODELS are acceptable to the PON provider and will those GPON modules sync properly. The only REAL solution is for MikroTik to provide firmware that does effective auto-negotiation. most PON providers usually insist that only their whitelisted devices be used.As I wrote in another post, Russian users have no problems using GPON modules with theirs RB4011. Perhaps not all GPON models are supported but GPON SFP Sticks from Zisa OP151S and D-Link DPN-100 are reported as working

@Error0x29A, YES you make excellent points.Has anyone tried to login into the SFP and using shell commands to change the rate to see if it connects to RB4011 at 1Gb?
.
I have not not tried to login into the SFP .... did not know that could be done because Root is locked on RoS ???
The standards are there and they are being strictly enforced ... and I believe that MikroTik adhere to the standards .... the problem is how the PON providers choose to implement their services and the control they want to exercise over the gear that runs on their network. There are very significant challenges implementing effective auto-negotiation protocols over fiber --- auto-negotiation is in effect an Ethernet Protocol and adapting it to fiber is not in any way a trivial task.This is what happens when you dont regulate industry and companies play these stupid games.
Make a standard and follow it.
The SFP Transceiver that Bell provides includes the ONT so I suspect that when Bell implement 10G their replacement SFP+ Transceiver will also include the ONT.So David, are you saying that in the near future we may be able to connect the RB4011 directly to the incoming fibre line from the street and bypass the ONT? I know the technician spent some time configuring the ONT to the account settings on their database (so they talk to each other). How would you do that on the RB??
The issue is the Sync Rate and whether the module is passive or active
So insofar as the RB4011 and its SFP+ port is concerned -- it only accepts Active modules that Sync at 1.25G or 10G and will not accept 2.5G for sync rate.
I am assuming that Bell move to 10G will have the ability to Sync at 10G so in that case The RB4011 SFP+ port could be used directly although its still a PON network so I could be 100% wrong --- its all very new to me.
IF you are wondering abut the difference between Active/Passive modules.
I WISH that MikroTik would better explain why they have chosen the Active method vs the Passive method for their SFP[+] === I suspect that its a lot easier to implement.
@tdw ... thanks for your input.You appear to be confusing Active vs. Passive optical networks with Active vs. Passive SFP+ modules:
All optical SFP[+] modules themselves are active as they contain electronics to convert between optical and electrical signals.
Only direct attach cables (DAC) can be active or passive - active cables contain electronics to amplify and condition signals, whereas passive cables are purely two twinax cables.
This explains the differences.
@tdw has a point: from router's point of view, any SFP connection to optical network (regardless if it's active or passive) is using "active" SFP module.The following provides an exceptionally good overview of How Stuff Works:
How Fiber-to-the-home Broadband Works
Thanks @mkx ...... so what you're saying is that due to MikroTik's SFP[+] implementation in Routerboards it cannot currently act as a GPON CPE due to lack of communication intelligence and may not be able to act as XG-PON CPE for the very same reason unless they add some needed communication intelligence capability.And such "intelligent" SFP modules need some support from router which router might not know how to provide. Due to this GPON by Bell might not work any better on Routerboards when they move to 10Gbps sync rate.

The Bell GPON ONU/ONT SFP transceiver is pre programmed to communicate with their OLT And the only thing that is special is that it only will SYNC at 2.5G .... Ubiquiti have some of their SFP Transceivers sync at 2.5 and those work transparently with the Bell GPON Transceiver ... no special additional programming required .... plus Ubiquiti have auto-negotiation working .... quite frankly Other than the issue of the sync rate I do not understand the issue with MikroTik.While Mikrotik has it's share of problems with proper operation of different SFP modules (even with basic things, such as reading diagnostic values like temperature, Tx & Rx power, ...) I don't think its the problem in hardware implementation of SFP ... SFP interface is well standardized. But then it comes to intelligence of SFP modules and how they interact with ROS ... how to, e.g., program certain behaviour (e.g. how to select ATM VCI for proper ADSL performance). If ROS doesn't know about those settings, you can't use such SFP module. And same goes for GPON speciffic settings, most important being ciphering setup (I guess encryption and decryption is done by ONT SFP module). With some luck, SFP might be configured with some power-on defaults (by some other device) and such module might work in ignorant CPE afterwards. If module expects to be set-up after initialization, then it'll be a miniature heating device when plugged in an ignorant CPE.
SFP+ interface compatibility settings with SFP optical transceivers
For MikroTik devices with SFP+ interface that support both 10G and 1G link rate following settings are needed to be set on both linked devices for required interfaces. These settings only relate when optical SFP transceivers are used. In order to get them working in 1G link rate, use the following configuration:
auto-negotiation disabled
port speed 1G
FD
Devices which SFP+ ports support 1G links:
>>>> RB4011 series - SFP+1 interface can be used in 1G mode if required. <<<<

So in CANADA if you want to use the RB4011 and its SFP+ port or any Tik Router with SFP[+] ports the above should help -- but if it does not work then something is wrong with How RouterOS interacts with its SFP[+] modules and only a firmware fix will correct that.The GPON SFP ONT supplied by Bell will act like an Ethernet SFP if you decide to put it into your own equipment.
Bell's GPON SFP ONT module will sync at 2.5Gbps in the router supplied by Bell .. It will sync at 1Gbps in everything else.
The GPON speeds are 2.488Gbps down and 1.244Gbps up -- If you want to run your own Router and use its SFP port you must use Bell's GPON SFP ONT
For the Huawei MA567A to work on the RB4011 you need to disable speed auto-negotiation on SFP port. Set the speed fixed to 1Gbit and the module will be detected. I have a RB4011 and a MA5671A working ok with Spain FTTH.I am on Bell 1G FTTH and got HUAWEI MA5671A SFP from Bell. 4011 can see the the module is present, but does not appear to be able to do anything else with the module, can't read vendor or any other info, no link obviously. The same module works fine in tp-link standalone media converter and in Ubiquiti ER-X-SFP router. I blame Mikrotik.
What about the CRS305?RB4011 seems to be even more picky than the rest.
