Hi,

Look here

Answer: Nobody's making 10GE CWDM-wavelength lasers. Why? I don't have enough knowledge of optical equipment, but my understanding is that it is because: a) Currently DWDM component suppliers already have a full load of orders and have problems scaling production - as evidenced by long lead times on any DWDM optics. b) They wouldn't be much cheaper to produce than temperature-stabilized DWDM optics. c) The demand is currently for amplifiable DWDM optics. -alex
