interface sfp duplex towards 2 front ports

[snorte]

There has to be some solution to get a standard sfp interface with a duplex singelmode fiber connection to two front port ODF...?

The best you can do currently is to run a single cable from the interface to the first port of the ODF, and mark the adjacent port of the ODF as "connected".

Alternatively, if your entire fibre infrastructure is duplex, then you can model each pair of LC ports as a single frontport.
