<div dir="ltr">If you use LX with multimode at long distances you generally need a mode-conditioning cable (which is basically a short length of single mode fusion spliced with some multimode). Using LX transceivers over short runs (between racks for example) when you have cable better than OM3 is mainly to preserve homogeneity of media types and is obviously more expensive than SX. <br></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature">Regards, Martin<br><br><a href="mailto:MartinVisser99@gmail.com">MartinVisser99@gmail.com</a></div></div>
