PCIe adapters supporting long distance 10GB fiber?

Re: DWDM Mux/Demux using 40G Optics

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. On Mon, Jun 19, 2017 at 4:52 PM, Faisal Imtiaz

Re: DWDM Mux/Demux using 40G Optics

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. On Mon, Jun 19, 2017 at 3:40 PM, Luke Guillory wrote: > If

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. http://public-wordpress-kkc.s3.amazonaws.com/wp-content/uploads/2014/07/Graph1.jpg -Original Message-

I guess that makes sense. The plus or minus some is the question. FS is claiming their 1310 port support QSFP+, which is 1270, 1290, 1310, and 1330 combined. I understand you can us 1310, but I am still scratching my head as to how they all one minus and two above 1310 to work. Of course they

RE: DWDM Mux/Demux using 40G Optics

My understanding is that ports on the client side would have cut filters for that color, having 1310 and 1550 are nice since you can hang gear you already have off the mux for OOB and so on. I don’t think I have any CWDM with expansion ports to test with. We use the following for simple

Re: DWDM Mux/Demux using 40G Optics

I'd imagine they vary based on vendor, so you'd have to check with the specific vendor in terms of absolute technical specifications. A 1310 and 1550 port only allow those channels plus or minus some, manufacturer dependent. An expansion port passes everything not used by that device. Some

Re: DWDM Mux/Demux using 40G Optics

Thanks for the answers. From the sounds of it, no one knows the real difference between the expansion port, 1310 port, and 1550 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

The issue is that once you get above 10g things start to get expensive since you don't have options for straight 40g optics in different colors. At least not what I see, 4x10g like you have or a single 1310 40g with no way that I see to mux them. I guess the only way this might work would be to
