PLEACE
make simple compact ADSL 2+ bridge modem , just to make dsl conect and send it out to rj45
and after use some mikrotik as router (make pppoe\ipoe ) and so on.
I would love to be proved wrong, but I don't think it can happen. Look at the size and number of components on a DSL module [Cisco, Juniper, Sonicwall] and I don't think you'd fit all those into an SFP. Maybe it could get into a GBIC but who makes kit with GBIC slots any more?I wonder if making SFP ADSL module is technically possible at all?
In addition, it would be best if it could be managed from within RouterOS itself, ie see the line parameters and conditions, etc. Oh and it would need to support VDSL as welljust to make dsl conect and send it out to rj45
How many ISPs are going to plug one of these in at their end for you to connect to?These must be used in pairs, with a CL-SFP module installed at both ends of the connection, or a CopperLine unit installed at one end.
