Re: Low cost WDM gear

[Faisal Imtiaz <faisal () snappytelecom net>]

Mike,

Lighting up dark fiber is very similar to doing fixed wireless links (which you are familiar with).

There are different components involved in making a solutions work.... for each of the problems you have stated there 
is solution, and yes you have to calculate the loss and match power / optics to make it work.

FYI.. all CWDM/DWDM Muxes are passive ... :)
Active components (can be external or integrated).
If you want to do a direct run, from DC to DC using the Dark Fiber, you will need to have signal regeneration (or you 
may be able to get away with amps).

It is commonly expected for the transport provider to hand off the live circuit using standard SFP/SFP+, which means 
that they have to use a 'media converter' of some sorts to covert from Colorized Light to Standard 1330 or 880nm hand 
off.

If you want more info, hit me off list.

Regards.
