Hello,
could it be possible to develop a GPON architecture to deliver FTTH services, using routerboards and SFPONU ?
As described in the attached picture, a single “access switch” (or rotuer) might be used, with a SFPONU, connected to a splitter.
The vertical distribution should be made of “single fiber cable” (e.g. Prysmian Verticasa).
The splitter could be this one http://www.prysmiangroup.com/en/business_markets/markets/telecom-solutions/downloads/datasheets/AC005-06_PLC_Splitters.pdf.
As CPE will be used a routerboard with another SFPONU, e.g. a 2011.
Could this be a working architecture? Are there any similar working deployment?
Thank you,
Rgrds
Maybe I’ve missed something, but I didn’t think that Mikrotik has an OLT SFP. The only GPON SFP I’m aware of is for the client side (ONT).
If this is still true, then you need to use some other vendor for the OLT, but you can still use a CCR1009 as the router.
Regarding the OLT SFPs, they are designed to work with specific GPON hardware, you can’t plug them to a standard SFP slot and create a PON out of it. The hardware for the “server” side of a PON is far more sophisticated and specialized, and, in fact, the OLT SFPs are just the physical component to the GPON technology. The “intelligent” part of the technology is inside the GPON header itself.
But in the client side you can use the MikroTik SFP (which contains all the client “intelligence”) as long as the OLT allows it to connect, because OLTs usually place restrictions on the ONT devices through obscured and propietary OMCI properties
Thank you for replies,
in effect, using it with Mikrotik to serve a limited number of customers in a building in not worth while, because of the small price of BIDI SFP.
E.g. a “OPTIC-SFP-3524S-02-SC” transceiver costs about 9€ and the price difference between a rotuerboard with one and ten SFP slots is small as well.
Nevertheless, it could be useful and interesting to have Mikrotik products that covers all the GPON chain (OLT/ONT).
Waiting for Mikrotik staff to amaze all of us with this new feature… ;-D
We are actively investigating a GEPON architecture and despite being a heavy Mikrotik user for many years this is making us look at alternatives on central nodes.
I agree that BIDI is cheap and efficient, but it fills a lot in volume on central nodes and requires singlefiber per customer (espcially with Mikrotiks low density) when there are multiple per house. We do not want local active equipment in the basement since we will need to maintain ups etc and make agreement with landlord.
So for us GPON pair for low end users and seperate bidi fibers for highend users using multifiber to users.
Well - today I finally got a Mikrotik (( 2011UiAS-2HnD )) with a Mikrotik GPON SFP talking to my Adtran TA-5000 head end.
You can pretty much forget about using google for help on this topic (Mikrotik GPON to Adtran) — I found nothing after a month of searching.
What you need to do is configure the head-end for your GPON network to treat the Mikrotik GPON SFP module like a regular GPON bridge device (NOT a residential gateway).
The Mikrotik SFP interface does NOT need a vlan - - Treat the Mikrotik SFP interface with the GPON module inserted just like a regular Ethernet connection.
FYI
I still have a lot of work to try and test. I want to get it to pass vlans - and possibly get a SubH (out-of-band-management) working on my Mikrotik.
I’m now looking at installing a 140 unit subdivision and I’d like to avoid a 16K solution with OLT and other fancy stuff, and just get an SFP that I can load into an adequately sized Mikrotik router/switch like a 2216 or some other SFP+ capable unit.
I’m looking to see what’s out there and what other operators have used. I got pricing from a few US name brands, I’ll check adtran. Fs.com has an off brand solution, but i’d rather stick with Mikrotik for the entire solution.
I see TIBIT has an OLT on a SFP, has any one used it with success with Mikrotik?
There are other SFP’s for about 300$ on FS.com or Fibermall.com that say 10x10gbps OLT, but I’m assuming they are meant to be installed in some OLT chassis like Calix or Nokia or Adtran or etc. Has anyone used these with Success? I was hoping that I could buy and OLT interface, and ONU interface, and they would just work like any other fiber interface, but in a PON mode just like a typical access point would with WIFI. NV2 over Fiber??
