Re: Low cost WDM gear

[Kenneth McRae <kenneth.mcrae () me com>]

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.

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. I assume I'd need an amplifier in the middle to even make it that far.

Are you looking for an active or passive solution?

One particular route I'm looking at is 185 miles, so of the options presented 300 km is closest. ;-)

would be good for mike to define 'long distances' here, is it: 
2km 
30km 
300km 
3000km 

Probably the 30-60k range is what you mean by 'long distances' but... 
clarity might help.
