Another Savior of Data Center MM Fiber?

January, 2015

In addition to the development of longer-distance and higher-speed VCSELs, there is a possibility that in the long term, polymer waveguide material embedded in electronics could also help to extend the life of multimode fiber in data centers. Yet right now, the technology appears to be reminiscent of the use of silicon photonics with active components, but without the hype. As with SI photonics, the concept of these types of waveguides has been discussed for many years with the problem of loss being a major concern, and right now, the vast majority of dialog on the latter can be found almost exclusively in engineering papers and patent applications. An exception has been Dow Corning, which has for a while been making somewhat of a marketing push, such as at trade shows with its short-reach interconnects utilizing “low loss,” silicone-based polymer waveguides. Back in early...
