Any tips on getting other people to use colored optics or is it not the iss=
ue that I'd expect it to be? This particular application would be to connec=
t two datacenters together over dark fiber and transport customers across a=
s needed. I could see it being a little difficult to get someone to buy spe=
cial optics (even if you can source generic ones) for your route. I wouldn'=
t have an issue, but then again, I'm fairly easygoing... and "thrifty."=20
Another scenario before me is within a datacenter when trying to save on cr=
oss connect charges. Spending a few thousand bucks once sure beats $300/mon=
th forever. I'm working with several other ISPs, some of which don't want a=
nother entity to be between them and their upstream. [Cut rambling short.]=
=20
I guess the short of it is, active solutions are expensive, so do that or d=
on't. ;-) I did get an AlcaLu quote under $25k once, but it wasn't far unde=
r.=20

Yeah, you can get up to 80km on a passive unit using SFP+ and up to 120km u=
sing XFP. To cover the distance you are considering, you would need to inse=
rt an amplifier. Depending on the number of channels you require, a passive=
solution with an amplified would still be less expensive than an active so=
lution. When I was conducting my research, I could not find an active solut=
ion under $25K.=20

Well, I'm not an expert in the world of long haul optics, but I think I'd w=
ant active over passive for the ability to use standard interfaces on the e=
quipment (routers, switches, etc.) at either end. Then again, maybe somethi=
ng 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.=20

Are you looking for an active or passive solution?=20

One particular route I'm looking at is 185 miles, so of the options present=

would be good for mike to define 'long distances' here, is it:=20

Probably the 30-60k range is what you mean by 'long distances' but...=20
