have you actually priced and deployed anything lately? Most any device with an SFP port will support Single mode.

Yeah the cost of single mode fiber and modules has dropped significantly in the last few years. Multimode is really only installed new now for rack to rack runs which are too long for DAC cables or for electrical isolation.

OP - If any existing switches have SFP ports, those can be used in place of media converters. All that matters is that the SFP modules on either end of any 1 fiber match. You can have a module at 1 end plugged in to a SFP port in a media converter and at the other end a module plugged in to a SFP port in a switch. So if you already have a switch at building B which has 4 or more SFP ports, you won't need any media converters there.
