Airtel Xstream And GPON SFP

Good choice on the router!
My RB5009UPr+S+IN should be here in a few days, it appears to be the cheapest option with enough CPU oomph to SQM / traffic shape 1 Gbps WAN. I'll post a thread on the whole process.

@ishanjain28 is correct, you want the ODI DFP-34X-2C2 which has the newest RTL9601D chip.
The Github repo he linked is the bible for swapping ISP optics.

I just received mine today, I got lucky and managed to get some samples straight from the factory where ODI buys from.
This will work:

If there's enough interest a group buy could be arranged in the future.

@Strykar yes buying in a group is better I got 2 ODI one and sold one to a forum member that way cost was nominal

Sadly the Mikrotik rb5009 is not for naive people like me but you guys can surely handle it .

have been using mine sfp in a media converter for the time being will plug it directly in mikrotik but will have to reset it to do that, my sfp settings are deleted. 😂 🙃🙃
Also ODI doesn't buy from anywhere their parent company is HSGQ and they only sell it they have stopped ODI now.
did they charge you for the samples when I asked they refused??

I have 2 SFPs right now, 1 unused. 1 SC/UPC unit from the fibershow retailer(ODI DFP-34X-2C2) on AliExpress another SC/APC unit from HSGQ on alibaba.

I am using the latter right now in rb5009upr and it does have some issues.


1. Mikrotik(or maybe the SFP) disable sfp interface if power drops below -27.5dbm which is causing problems because the power in my case hovers between -26.8-27.9. It worked fine with genexis ont because they just keep working. Or it may not be disabling interface due to power issues but some thing else weird is going on. i'll try to investigate it in upcoming weekend.

2. Auto negotiation does not work properly. 1g-base-X works perfectly fine and on 2.5g-base-X, I was seeing TX Queue drops and icmp echo requests to sfp interface were timing out frequently. You are supposed to set LAN_SDS_MODE on SFP to 6(see docs). It works better after that but still not quite perfect.


I will ask my isp to fix power and then maybe switch back to using the SFP unit
 
@anmolbhard004 you got free units, WTF?
I paid for mine at HSGQ's Alibaba store and someone who lives in India working there was traveling to MAH and shipped them here locally.
A sales rep at HSGQ told me ODI is a vendor, I haven't checked company details.
The Jan 17th flyer was shared with me but I am not traveling to Delhi for a NIC.

@ishanjain28 Luckily I was asked (I had forgotten) if I wanted APC or UPC before shipping and I confirmed it was APC with Airtel so saved some money. Your ISP is the easiest solution to the power issue, the other is updating the driver and compiling a new firmware and hoping the hardware plays nice. On my Dasan H680GM-A, the RX is at -20 and TX is 2.2, which is assume is in dB or dBm.

Did you post on the Mikrotik forums about the issue at 2.5 Gbps? If you look at the block diagram, all the ethernet and SFP ports are controlled via the switch chip, so with the right logs, Mikrotik can definitely fix this. I will keep an eye out for this, since my desktop has an onboard 2.5 GbE NIC, it might show up on ethernet too, thanks for the heads up!

I just looked up LAN_SDS, did you try to change mode to 5 (HiSGMII MAC) and see if the issue persists?

@Strykar no I didnt got free units I was asking you the same , I paid.
they gave me a upc to apc connector but its faulty.
have ordered a new one from ubiquiti store.

tell me once you set the sfp with your mikrotitk.
 
There is a bug in the latest firmware which does not tag VLAN correctly if set in the stick. You have to set it to passthrough mode and set VLAN in your router. So please be aware of this issue.
 
LAN_SDS_MODE=5 is not stable either. After making the change, tx queue drop was at 54 for a few hours then some thing happened and now it's at 11.5k. Switching it back to 1g full duplex for better stability for now. I'll make a post on Mikrotik forum later
