Re: SFP module for 100km

said by Rhaas:

That seems high to me, I assume that there may be some connectors (not splices) in there?

That link is long for sure, is it a bs splice or a connector(s) who knows, heck there could be a couple of biconic's in that span.

Personally I would (if possible) kick it back to the who ever placed the fiber to begin with and an OTDR to locate the loss(s) and clear them, lacking that I would push for a larger light budget, that is if the SFP’s can handle those levels.

@MatrixHDV
LX16 has a linkbudget of 37db and manufacturer states that these values are with %10 over performance to secure the specifications.

Do you think that we should consider a higher link budget than LX16 ?

Guess that depends on the cost as you can always pad the receive down, but if the fibers come up long you cannot gain up...
