Big Need for MPLS-TP?

August, 2014

At the service providers across the globe, the most widespread and native selection is MPLS and not MPLS-TP. The former has broader acceptance, superior interoperability, and operational intimacy for the engineering folks. In Asia, particularly China, MPLS-TP has taken off in a big way. While some industry observers view that part of the world as exceptionally unpredictable and may suggest that “TP” could even be replaced, it seems that at least one of the large Chinese operators has such a critical mass of deployment that such a move is not imaginable. On its face, one would think customers should want to go with MPLS-TP over MPLS because the former is a newer version. Ordinarily, any supplier that would happen to start product development from scratch would definitely be inclined to begin in the “TP” direction. Theoretically, MPLS-TP should be a slam-dunk in a greenfield situation at ...

25G Laser Shortage

August, 2014

We have been told that there is going to be a worldwide shortage of 25G lasers in the coming two years, supposedly due to not enough capacity having been planned by the industry as a whole.  We hadn’t heard anything like this before.  Do you guys know if this is true, and if so, why it happened? A couple of our contacts indicate that supply is down because of unexpected demand by a few data center operators as well as a greater need for customized optics, and that 25G lasers have inherently lower manufacturing yields than is the case, say with 10G devices. Specifically, the 25G DMLs are in short supply, not the EML devices. However, the EMLs are very expensive, especially for short-distance applications. There is also apprehension that expanding production will create a long-term overcapacity situation, once the market gets back to normal levels. In the meantime, it has become a waitin ...

Videoconferencing: The Elusive Business Application

September, 2014

Although it was 50 years ago that AT&T introduced the Picturephone at the World’s Fair, the company is still striving to “encourage the adoption of videoconferencing” at major corporations today. There has just not been a significant cultural shift in the business community to making deals without shaking hands in person. Yet, there are also very practical considerations in videoconferencing providing an inadequate sense of being in the room, and not allowing for a close consideration of body language to assess the impact of a presentation. While webinars have undoubtedly reduced the amount of traveling substantially in prequalifying sales prospects in offering graphical video displays in communications, there is no real need to have a live picture of the people in the conversation. So, videoconferencing is partly about using a solution in which there is not a problem. Also, somewhat iro ...

A Kaiam Strategic Partner: Google?

September, 2014

Concerning the recent $35 million announcement by Kaiam of equity funding, our intelligence indicates that one of the two strategic partners is Google. We also think the other partner is Microsoft. In addition, we believe that the total valuation is two to three times revenue -- so over $70 million. While Kaiam has clever packaging, we are not convinced that it has the lowest cost in the market. Nevertheless, the supplier has benefited from getting out there early in the data center/datacom space. It is likely that it owns the 10x10 business in that sector. Unquestionably, signs of two giant enterprise firm funding Kaiam may be about ensuring direct access to unique 100G technology. Perhaps it is the vendor’s Hybrid Mixer PLC – and/or maybe something else that could possibly be on the drawing board that involves a coherent, serial 100G device. More practically speaking, there is a higher ...

Bullish on 850nm VCSELs; Avago Selling VCSEL Components

March, 2015

As we will demonstrate on an OFC 2015 panel, the data center VCSEL market will remain healthy for an extremely long time, especially in terms of steady revenues. The most shocking change is based on recent evidence that Avago Technologies is selling VCSEL components, possibly including as far down the food chain as bare die, to at least one interconnect solutions provider and at the request of a minimum of one very large enterprise. In even reading between the lines of a small portion of the transcript of the latest quarterly report from the vendor, it indicates a move in this direction: "...[W]hen you start talking about 25[G], you’re talking about having to drive short-reach or even longer reach native 25, which makes it very tough to produce laser, VCSELs, laser, so to speak, that does 25 gigabit. We are one of the few guys who can do it. And we happily sold it to guys who do 100 giga ...
