If their 1310 passes them I would have to think you can't use is with other client ports that would fall within the window. Here is a graph showing those 4 for the 40g it seems.

Luke,
I agree, I would be talking about getting one with the 1310NM special port
for the QSFP+ input that emitts 1270-1330nm light, and then say 4 client
ports on different channels than that light range.
From the sounds of it, no one knows the real difference between the expansion port, 1310 port, and 1550 port
Hmm.. not sure how you are reading this...
I believe that there is no 'standard' and as such the actual filter on the mux/demux you are using may vary by mfg.
I can confirm what is an expansion port... (pass everything thru that is not being filtered by the mux/demux )
I can also confirm that Fiberstore 1310nm port (not to be confused with the CWDM 1310 port) will pass all 4 wavelengths for 40g/100g optics.
I don't have experience with the 1550nm port.
For real world applications, I would assume the monitor port would be to plug in a handheld meter, and see which channels are coming through that node without breaking the ring.
Correct that is what it is designed for..... it allows a fraction of light (I am guessing would also cause an increase in insertion loss figure).
Not sure if their would be a monitor port for both directions is you were using a OADM?
If you look at the OADM's e.g. like a Cisco CWDM OADM with monitor ports, you will see that they are on both sides east & west.

Do you have any idea if fiberstore has one with both a monitor and 1310
wideband port? I would want both.
Seeing as how they don't charge extra for an expansion port, but do for
other special ports I am thinking of just using the expansion port.
You can see the CWDM mux listed on their site, and they will also make custom mux for you.
Let me know if you need a Sales Contact for them..
My last set of muxes from them were custom muxes and they were able to get me a configuration with a lower insertion loss than what is listed on their website. ( I paid a small premium for that feature, which I was very happy to).

Another alternative is to ask the http://www.beetlefiberoptics.com guys.
They build muxes on spec and they can also provide a 1310nm wide-band port on their units which allows a 40/100G-LR4 aside from the 1550nm DWDM band.
We’ve used some simple splitters (line/1310nm LR4/1550nm DWDM ports on a unit) and full passive DWDM muxes with a 40/100G-LR4 port on there and these work pretty good.

Besides FS.com and http://www.beetlefiberoptics.com, do you have any more
recommendations for passive muxes? I usually stick to and like FiberStore,
but I am wondering if there is anything out there better/cheaper.
One of the things I am noticing is the CWDM and DWDM SFP+ optics are quite
expensive at $250 for CWDM and $350 for DWDM. I guess it shouldn't be
cheap to send 10G around a ring, but I am wondering what transponders cost.
Hi,
Ex CubeOptics (now Huber Schuner) are just great. Been using them for years, rock solid. I highly recommend them.
Best regards.
