I've been looking at using MOCA 2.0 to extend my wired network, and will probably end up using a pair of Actiontec ECB6200 devices.
However, MOCA is more or less it's own layer2 entity, and apparently there are routers/waps/STBs which can connect directly to MOCA.

I know that Mikrotik is very very very unlikely to be interested in making a router with a MOCA interface, but perhaps a MOCA SFP would work...
Has anyone heard of such a thing? It would be a nice tool in the box if one were to use a pair of them to bridge between a central router and some hAP AC units, for instance....

I have very good experience with MoCA but only with separate boxes (on ethernet port) like you mention.
SFP would be difficult I think, because of the physical size of the F-connectors you would always need an external box
on the SFP, and probably the electronics are also too big.

But then, I also thought his when thinking about a VDSL SFP, and in the meantime we have seen that on paper it now exists.
(not in reality, I think...)

If Mikrotik innovated with SFP for the home, they could also do it here.

But better not waste effort in versions overlapping DOCSIS 3.1 .

A DOCSIS 3.1 SFP would be pretty cool too. I already have a modem and speeds aren't that high here so given that I only have 1 slot, I'd opt for MOCA if both existed.

Have you heard of any DOCSIS SFPs?

If I could crowdfund the project I could see using Microsemi's IGLOO® nano low-power FPGAs


and Analog Devices AD9364

perhaps it could be done.
