<div>Qui,</div><div><br></div><div>It might work, but you definitely need the Mode Conditioning Cable (to make sure the single mode optics in the transceiver launch down the side of the multi mode core). But you are right on the limit for a single fibre run. Each patch will add loss - and with six it all adds up. Unfortunately most enterprise network equipment is pretty much go or no-go as far as determining whether it works. You probably either need a OTDR test done on the run, or run things and 100BaseFX.</div>
