Good day!
I want do build a little network based on GEPON. Maximum clients per OLT - 64 ONU-s.
I find RB2011LS-IN model with SFP module support.
And I find many OLT SFP modules on alibaba.com like this model http://www.alibaba.com/trade/search?fsb=y&IndexArea=product_en&CatId=&SearchText=gepon+olt+sfp
I want to build FTTH in small village.
The question is - can I use RB2011LS-IN with OLT SFP module on as GEPON OLT?
+1 for that
What kind of GPon system are u using or u are going to use?
Hi Lakis!
I don’t use PON type network just now.
This idea became after than we decided to build a small network for village with 300 houses.
We are thinking that we will have 100-150 clients maximum in this village.
So we chose Passive Optical Network for this place.
We want to use GEPON (IEEE 802.3ah) because its equipment are cheaper then GPON (ITU-T G.984).
GEPON ONU 10/100Mbit is about 30 usd.
GEPON OLT with one PON port is about 750 usd.
But if mikrotik will support GEPON OLT SFP Module we can get
1 - OLT for 200 usd!
2 - flexible integration with our existing network on mikrotik
3 - OSPF, BGP, MPLS … can be used for future
4 - I like mikrotik 
Maybe you will find this interesting:

Thank you for your attention.
But may be you don’t understand my question fully?
This is SFP GPON ONT module - client side . and this is not GEPON (EPON) device - this is GPON (ITU-T G.984)
My question is OLT on mikrotik
I tried to understand differences between GPON and GEPON. I understood GEPON is more cost effective solution and throughput is 1Gbps. But GPON has 2.5Gbps/1.25Gbps. I don`t understand why GEM of GPON is good for us. Why we need ATM support this days? IP network is enough to provide all kind of services?
about terminology http://www.thefoa.org/tech/ref/appln/FTTH-PON.html
Yes. You are right. GPON give 1.25Gbps up/down for Data and 1.25Gbps down - Video.
So GPON OLT has 2 laser for TX(1550nm and 1490nm) and 1 reciever for RX (1310nm). And GPON ONT has 2 reciever (1550nm and 1490nm) and 1 laser for TX (1310nm).
GEPON OLT or ONT/ONU has only one TX and one RX. So GEPON equipment is cheaper than GPON.
I don`t understand why GEM of GPON is good for us.
I know why PON good for me look on this picture
You need only one optical fiber to connect up to 64 ONU/ONT per one PON port. You can split one fiber to many with splitter 1:2 or 1:4 … 1:64 how you want in range 10km!
Why we need ATM support this days? IP network is enough to provide all kind of services?
I don’t need ATM, GPON protocol - “Ethernet over ATM/IP or TDM”. GEPON - only Ethernet.
realtime any news about that?
we use Teknovus TK 3723 gpon
I m really curious if there is compatible GPON OLT SFP with MT
most[PON vendors HW]firmwares presently support encryption only in downstream.
that prevent fishing/snooping on downstream[downloaded traffic], but clearly open your work[including cleartext passowords and other stuff]open for sniffing/decoding by bogus/altered/specially-crafted hardware/firmware on same [splittered]segment.
didn’t saw OLT SFP cage yet, nor firware for baseline things[not “PON”-labeled], but thats maybe my personal proble/experience.
Would be nice to see OLT on mikrotik aprox 1000usd solution!
yeah, adding GEM support would be nice.
rest was[name VLAN, IPv6 and etc]- already here.
until that 2011 couldn’t be even ONT, i guess/suppose.
p.s.
heavvy encryption in downstream - mean more load on CPU on high bandwitch.
not sure that used 74kc[single-core without FPU] can do it. maybe derrivative with 1074kf can do ?
also this model can had SFP+ port[it can be implemented with retaining SFP compatibility(but not vice versa)].
Maybe mikrotik staff have some comments about OLT implementation on routerOS?
Hi Realtime.
I see that you have bought GEPON ONU 10/100Mbit is about 30 usd.
GEPON OLT with one PON port is about 750 usd.
Can you please let me know the vendor/manufacturer you have bought it from?
The reason being, i am working on one of the deployments here, and i am recommending the operators here to go in for gepon which is cost effective instead of copper EOC models.
If what you said is the price and also working fine, i would like to talk to the manufacturer for placing an order.
Please do let me know
Thank you for the feedback. We are monitoring this topic and consider your suggestions.
Any news about that?.
I’m looking for a sfp gepon olt to attach into rb2011ls.
Any of you have the same scenario?
+100000000000
I ordered GPON OLT sfp and ONT sfp. They are on the way. Let`s see possible to use with routerboard or not.
Hi,
we are also searching for an gpon-solution, to use mikrotik for this too would be very nice.
Any news about this?
Received in our country last week in Custom Office. But didn`t receive in my hands yet. Waiting…
I am also extremely interested in your results, we are also looking to do something similar Let us know what you find
