If it's too high, you'll need to attenuate the TX power output from the LR optic.</span></div><div id="yui_3_16_0_1_1436142077504_121274"><span id="yui_3_16_0_1_1436142077504_121410"><br id="yui_3_16_0_1_1436142077504_121409"></span></div><div id="yui_3_16_0_1_1436142077504_121274"><span id="yui_3_16_0_1_1436142077504_121336">If you can't measure/calculate it you can use an in-line attenuator on just the TX fibre from the LR optic. They're pretty cheap, buy a handful at different attenuation levels. Set the gear up with 15dB attenuator, check the receive levels, if too low, swap to a lesser attenuator until you get something that is workable.</span></div><div id="yui_3_16_0_1_1436142077504_121274"><span><br></span></div><div id="yui_3_16_0_1_1436142077504_121274" dir="ltr"><span id="yui_3_16_0_1_1436142077504_121447">This of course relies on having workable DOM that will report the TX/RX levels to you.</span></div><div id="yui_3_16_0_1_1436142077504_121274" dir="ltr"><span><br></span></div><div id="yui_3_16_0_1_1436142077504_121274" dir="ltr"><span><br></span></div><div id="yui_3_16_0_1_1436142077504_121274" dir="ltr"><span>regards,</span></div><div id="yui_3_16_0_1_1436142077504_121274" dir="ltr"><span>Tony.</span></div><div id="yui_3_16_0_1_1436142077504_121272"><span><br></span></div><br> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 13px;" id="yui_3_16_0_1_1436142077504_121181"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, Sans-Serif; font-size: 16px;" id="yui_3_16_0_1_1436142077504_121180"> <div dir="ltr" id="yui_3_16_0_1_1436142077504_121189"> <hr size="1" id="yui_3_16_0_1_1436142077504_121271"> <font size="2" face="Arial" id="yui_3_16_0_1_1436142077504_121188"> <b><span style="font-weight:bold;">From:</span></b> Skeeve Stevens <skeeve+ausnog@eintellegonetworks.com><br> <b><span style="font-weight: bold;">To:</span></b> "<ausnog@lists.ausnog.net>" <ausnog@lists.ausnog.net> <br> <b><span style="font-weight: bold;">Sent:</span></b> Wednesday, 8 July 2015, 17:13<br> <b><span style="font-weight: bold;">Subject:</span></b> [AusNOG] LR to LRL<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_1_1436142077504_121179"><br><div id="yiv8291227842"><div dir="ltr" id="yui_3_16_0_1_1436142077504_121178">Hi guys,<div id="yui_3_16_0_1_1436142077504_121220"><br></div><div id="yui_3_16_0_1_1436142077504_121221">Just wondering if anyone know of risks of using an LR (10km) optic to an LRL (1km) optic are... will they work fine, or will the LR burn out the LRL.</div><div id="yui_3_16_0_1_1436142077504_121222"><br></div><div id="yui_3_16_0_1_1436142077504_121223">Thanx!<br clear="all"><div id="yui_3_16_0_1_1436142077504_121231"><div class="yiv8291227842gmail_signature" id="yui_3_16_0_1_1436142077504_121230"><div dir="ltr" id="yui_3_16_0_1_1436142077504_121229"><div id="yui_3_16_0_1_1436142077504_121228"><div dir="ltr" id="yui_3_16_0_1_1436142077504_121227"><div dir="ltr" id="yui_3_16_0_1_1436142077504_121226"><div dir="ltr" id="yui_3_16_0_1_1436142077504_121225"><div style="font-size:12.8000001907349px;" id="yui_3_16_0_1_1436142077504_121224"><br>...Skeeve</div><div style="font-size:12.8000001907349px;" id="yui_3_16_0_1_1436142077504_121232"><br></div><div style="font-size:12.8000001907349px;" id="yui_3_16_0_1_1436142077504_121237"><div id="yui_3_16_0_1_1436142077504_121236"><div style="font-size:12.8000001907349px;" id="yui_3_16_0_1_1436142077504_121235"><div style="font-size:12.8000001907349px;" id="yui_3_16_0_1_1436142077504_121234"><b style="font-size:13px;font-family:Calibri;" id="yui_3_16_0_1_1436142077504_121233">Skeeve Stevens - Founder & Chief Network Architect</b><span style="font-family:Calibri;font-size:13px;"> </span></div><div style="font-size:12.8000001907349px;"><span style="font-family:Calibri;font-size:13px;">eintellego Networks Pty Ltd</span></div><div style="font-size:12.8000001907349px;" id="yui_3_16_0_1_1436142077504_121239"><span style="font-size:13px;font-family:Calibri;">Email: </span><a rel="nofollow" ymailto="mailto:skeeve@eintellegonetworks.com" target="_blank" href="mailto:skeeve@eintellegonetworks.com" style="font-family:Calibri;font-size:13px;" id="yui_3_16_0_1_1436142077504_121238">skeeve@eintellegonetworks.com</a></div><div style="font-size:12.8000001907349px;" id="yui_3_16_0_1_1436142077504_121241"><div style="color:rgb(0,0,0);font-family:Calibri;font-size:13px;margin:0px;" id="yui_3_16_0_1_1436142077504_121240">Cell +61 (0)414 753 383 ; S<a rel="nofollow" href="">kype: skeeve</a></div><div style="color:rgb(0,0,0);font-family:Calibri;font-size:13px;margin:0px;" id="yui_3_16_0_1_1436142077504_121448">LinkedIn: <a rel="nofollow" target="_blank" href="http://linkedin.com/in/skeeve">/in/skeeve</a> ; Expert360: <a rel="nofollow" target="_blank" href="https://expert360.com/profile/d54a9">Profile</a></div></div></div></div><div id="yui_3_16_0_1_1436142077504_121242"><br></div></div></div></div></div></div></div></div></div>
