So, to me that sounds like I do need to add (subtract) that from the link budget ??

So 8:1 passive mux is 2*2*2 so 9 dB theoretically, 11 or so in real life.

A mux is a mux. Just pay attention to insertion loss numbers to make sure you still have the optical budget you need. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP -------------------------------------------------------------------------------- From: "Paul McCall" <[email protected]> To: [email protected] Sent: Friday, April 14, 2017 5:29:16 PM Subject: Re: [AFMUG] Backhauling fiber 80 miles at 10Gig Is running an 8 channel mux any more reliable than a 40 channel mux on a link of that distance?
