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.
