In a recent post, I mentionned a handful of test & measurement players, silencing numerous companies. The reason is pretty simple : IMHO, Agilent Technologies, Danaher's Fluke+Tektronix, Anritsu, and JDSU are the only companies aimed to survive the forthcoming T&M industry shake-up. We are the verge of a new booming era in the Telecommunications, thanks to the enormous demand for bandwidth worldwide. Hence the mandatory consolidation in some sectors, Test & Measurement being one of the most vibrant.
That's why my take is, lots of the small guys will disappear one way or another. Mergers, acquisitions, banckruptcies, the whole range of possible futures is wide open for the EXFOs, the Spirents, the Ixias, and the one small firm somewhere down the Silicon Valley which I can't mention anymore (hint : they have a very very little useless subsidiary nearby the Leman lake, and their name is the opposite of the moon going dawn). Even the Yokogawas will face the big question someday...
In 10 years from now, I see only three survivors out of the Four-Tops above : Agilent, Danaher, and Anritsu. Don't ask me why : just a bit more than a feeling, from a 25-years presence in this industry. It has to do with their history, legacy, and roots, somehow.
Nevertheless, there is one thing I can tell : I'll do my very best to play a pro-active part in this shake-up, thru the Testing 2.0 adventure. See you in 10 years !
