Datacom Transceiver Vendors Transitioning into New Businesses

Have you noticed that it seems like all of the top datacom transceiver suppliers are transitioning their businesses? I’ve already talked about Avago’s new venture with its MicroPOD technology. They seemed to have supplanted Finisar as the technology leader in the space. Finisar has expanded its offerings into more telecom markets and JDSU is all but gone from the scene and focusing more on telecom again.

Finisar seems to be enjoying what may well be short-term success with its Laserwire offering. Since it is a non-standards based solution, it is difficult to believe it will become a mainstream one. While Finisar is offering other AOCs—C.wire (CXP-based) and Quadwire (QSFP-based), it does not seem to be participating in what seems to be a chip-to-chip optical interconnection revolution like Avago and Luxtera are (see previous posts for details) . Finisar used to be the technology leader in the optical transceiver space, it has veered off-course from that strength in preference for market diversification instead—now covering telecom and HPC standards-based solutions as an alternative. But perhaps this is the right move for Finisar, since it has not seemed to hurt its revenue position at all.

JDSU seems to be absent from the short-reach module market. It appears that the optical components giant has taken the technology that was developed at IBM, E2O and Picolight and thrown it away. Picolight was once a leader in parallel optics and, along with E2O, long-wavelength VCSELs. IBM pioneered v-groove technology and the oxide layer that enabled the next leap in speed and improved reliability for 850nm VCSELs. All of these technologies look like they are destined to die a slow, painful death after being acquired by JDSU. The company’s attention is clearly focused on its tunable technology and telecom applications, which is where, of course, it started. JDSU has never had a good reputation for assimilating acquisitions, so none of this should be a surprise. I was optimistic when JDSU bought these companies thinking that now these emerging technologies would be supported by a larger pocketbook. What was the reasoning for JDSU deemphasizing the technologies it acquired? Was it trying to get rid of short-reach competition in hopes that all optical networking would move towards long-wavelength devices? This would have been naïve; the likes of Finisar, Avago, MergeOptics and others would still be supporting 850nm optics and there remains a healthy market for them in enterprise networks and data centers—albeit a very competitive one.

According to JDSU, it is focusing on the LH and ULH versions of 40G and 100G first because it does not see the value in the CXP module for short-reach applications. For short-reach, it is focusing on QSFP+ modules, but development of these will take longer. The company claims it is not de-emphasizing its 850nm technology, but just focusing elsewhere first. I’m not so sure. Rumor has it, and I tend to believe that JDSU is looking for buyers for its short-wavelength business.
