Your OM1 patch leads have a 62.5 micron core, connected to an OM3 50
micron core. So you are probably seeing a small amount of loss -
but perhaps it's so small it's negligable. In particular I suppose
the transmit side being smaller than the receive side, is likely to
be 'doable' with minimal losses.<br>
<br>
I would certainly ensure you have the same type of fibre end-to-end
to ensure reliable service; do it as part of a planned outage now,
before it becomes an unplanned outage later when someone 'nudges' a
cable and ruins things ... !<br>

<p class="MsoNormal">Hi<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Our Data centre built several years ago
using multimode to be compatibility with existing MMF
infrastructure.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Recently we have an electrician audit
report that our fibre cabling between our inter-racks are MMF
OM3 but the patch leads we use are OM1.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are not sure if this cause performance
issues or data loss but we cannot see any errors in our fiber
switches or in our Cores.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is it worthwhile to replace these fiber
Patch leads to OM3 ?<o:p></o:p></p>
