Ken, it is the leader in optical netwotrking and is being run up like JDSU, SDLI and Ciena (the best of all investments over any time period recently in the sector.) as well as other leaders like BRCM, JNPR, CREE, AVNX and RBAK. When value matters again, they will all fall the hardest (since the internets are not going to run up nearly as high, though I see a few getting a bit frothy again). There will be another slaughtering imo. I am long a few right now, short SONS and RBAK, going short the others at earnings. I plan to use AMCC as a test rat this week. Earnings are on the 12th. Today was a great day for my SONS.... tp

The Qtera engineers told me at OFC that they were not using solitons, rather that they were using raman amplification to achieve their distance between regeneration. FYI Solitons are an alternative way to extend the distance between regeneration. The reason that signals need regeneration is as an optical pulse travels over a physical fiber the pulse changes shape, typically the leading edge travels slightly faster than the trailing edge due to refraction in the fiber. After 1000Km or so, the pulse becomes considerably more difficult to read and may bleed over into the previous pulse. Soliton technology resolves this by transmitting a pulse that is already distorted, but in a way that the natural refraction of the fiber brings the pulse into sharper focus rather than distorting further. As you can imagine, this is very difficult technology to implement. Research in soliton technology has gone on for more than a decade and there are still no commercial products.
