I hate to say this.... .the match on mux insertion loss does not add up in this manner... (I think you are thinking of GPON Muxes... not the same as CWDM or DWDM)
Always best to Check the MFG Specs.... (I have 8 channel CWDM muxes which have a low insertion loss (less than 2db on each lambda ! ) :) Faisal Imtiaz Snappy Internet & Telecom 7266 SW 48 Street Miami, FL 33155 Tel: 305 663 5518 x 232 Help-desk: (305)663-5518 Option 2 or Email: supp...@snappytelecom.net > From: "Chuck McCown" <ch...@wbmfg.com> > To: af@afmug.com > Sent: Friday, April 14, 2017 7:05:25 PM > Subject: Re: [AFMUG] Backhauling fiber 80 miles at 10Gig > Passive optical muxing is just a cascade of splitters with the 3dB per split. > So > 8:1 passive mux is 2*2*2 so 9 dB theoretically, 11 or so in real life. > From: Paul McCall > Sent: Friday, April 14, 2017 4:31 PM > To: af@afmug.com > Subject: Re: [AFMUG] Backhauling fiber 80 miles at 10Gig > Does using a mux require a “better” optical budget? > From: Af [mailto:af-boun...@afmug.com] On Behalf Of Mike Hammett > Sent: Friday, April 14, 2017 6:31 PM > To: af@afmug.com > Subject: Re: [AFMUG] Backhauling fiber 80 miles at 10Gig > Not really.
