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.<o:p></o:p></p></div><p class=MsoNormal style='margin-bottom:12.0pt'><br clear=all>Regards, Martin<br><br><a href="mailto:MartinVisser99@gmail.com">MartinVisser99@gmail.com</a><o:p></o:p></p><div><p class=MsoNormal>On 20 April 2012 10:44, Qui Le <<a href="mailto:QLe@sydneyoperahouse.com">QLe@sydneyoperahouse.com</a>> wrote:<o:p></o:p></p><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>We run 550m of OM1 fibre from our Cisco core to a remote site over 6 hops included rack to rack and we can not<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>seem to get any connectivity.
