That's true up to a point. Specs are only as good as the entity providing the data. I can tell you a few stories about specs and some MAJOR fails by a major network equipment manufacturer failing to meet advertised specs. When you engage the engineering folks to assist in a build, they should know the true specs of their gear better than anyone else. If they say for a certain distance that A+B will work, then that is exactly what I expect. That is pretty basic.

Hi Enviado, I cannot recommend FiberStore as I had a bad experience with them. I needed to cover only 3km from A to B side. When using 10km optics, I saw a loss of over 5db with their passive mux inserted into the path which created a total loss of over -20db which is outside of the tolerances for our equipment with 10km SFP+. Using another vendors low insertion loss mux corrected our issue. I am sure if you are using an 80km optic, you may be able to tolerate a higher insertion loss to cover < 60km. I also notice that their CDWM optics averaged about 3db less in power output when compared to other vendors.

Low cost WDM gear
by Kenneth McRae 07 Feb '15

Faisal, I worked directly with FiberStore's engineers to determine the optics and mux needed for my use case. They recommended the mux and the optics for the 3km distance. You can always buy stronger optics, but that is not point I am making. I provided the scale and scope of the project and they provided the BOM to deliver the required service. When the equipment failed, FiberStore refused to honor their return policy and issue an RMA until we threatened legal action. Same sales scenario with OSI Hardware.. They provide the BOM with passive muxes and 10km optics and it works with no problem. In this scenario, I can definitely blame the manufacturer. No to mention the terrible technical support that they offer.

Yeah, you can get up to 80km on a passive unit using SFP+ and up to 120km using XFP. To cover the distance you are considering, you would need to insert an amplifier. Depending on the number of channels you require, a passive solution with an amplified would still be less expensive than an active solution. When I was conducting my research, I could not find an active solution under $25K. On Feb 07, 2015, at 10:32 AM, Mike Hammett <nanog(a)ics-il.net> wrote: Well, I'm not an expert in the world of long haul optics, but I think I'd want active over passive for the ability to use standard interfaces on the equipment (routers, switches, etc.) at either end. Then again, maybe something has changed that I don't know about. I would also think active would be better able to go those 185 mile distances than passive.

My organization is currently shopping for some additional Transit Capacity to augment our existing interconnects. We've got around 8 distinct AS's that we're receiving transit routes from, followed by a handful of Public IX's and Private PNI's to AS's that warrant them. That said, the networks that are on our radar are Cogent and NTT. I've done some due diligence poking around on their Looking Glass, but I'd love to hear any user experiences from the community, both from a Layer 3 Perspective, as well as an Operational Perspective (Working with the businesses themselves). Feel free to contact me off-list and thanks in advance for your time.
