Yes, sorry I should've specified 10Gig-E and I would like to avoid using CWDM/DWDM optics if possible I would just like to use regular LR optics.
The common misconception is that, just because you're not installing colored optics directly in your router, something similar doesn't live elsewhere in your system, mingled with a number of OEO conversions. Neat packaging and pretty GUI is orthogonal to cheap, and you stated both as initial requirements, so you're probably best choosing one or the other. We may differ on levels of frugality, however I can't think of any active system I'd classify as "cheap"; at the base, you're looking at a 2x multiplier from something assembled with cubes, however you slice it... If you find yourself stuck with SFP+ interfaces, or partners who don't grok this stuff and require a "conventional" LR hand-off, perhaps a 2xXFP transponder is really what you're after -- feed your mux with the colored optics, and the other end with some LR (or SR, CX4, ...). MRV has some good products in this space. HTH, -a
