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. On Tue, Jun 20, 2017 at 3:55 AM, Jeroen Wunnink <Jeroen.Wunnink@gtt.net> wrote:
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.

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.
