I guess that is the real question. Besides the client ports that are clearly identified by channel number on Muxes, what channels can the special ports handle? http://www.fs.com/products/43723.html It has 4 special service port options: 1. Expansion Port (Based on what I am seeing, I think this would be to stack another mux if you needed more channels. So I assume it allows all channels to be added besides the client channels?) 2. Monitor Port (I think this is just a tap that you would hook a monitor up to, and be able to see all channels coming through with a meter. I assume not a good idea to add/drop channels through this port)? 3. 1310nm Port (Labeled as 1310, but clearly allows more than just 1310 since tutorial is saying it supports QSFP+ which is 1270 - 1330 nm, so what range does it really support or is there no a range?) 4. 1550nm Port (Labeled as 1550nm, but I wonder if its like the 1330nm?) Would you recommend a monitor port on every mux you buy? On Mon, Jun 19, 2017 at 2:18 PM, Mike Hammett <nanog@ics-il.net> wrote:
Verify pass-through frequencies for the 1310 (or equivalent) for the passive mux in question. This would only work for a single channel.

Faisal,
How would he inject his current 4x10 40g into the mux which is currently on a single LC cable?

Answers in-line below.
If you look at the CWDM Muxes (8 or 9 channel) you will notice a common configuration of
Upgrade Port (expansion port) + 1450 or 1470 to 1610nm
in the DWDM muxes you will see them listed as # of Port + 1310 pass thru channel.
These are exactly what you are looking for ..... :)
