Intel has been awarded three optoelectronics patents, InfoWeek reports. They're apparently related to the prototypes it demonstrated in September of a working silcon-laser modulator-demodulator which can support a communication link of 40 Gigabits per second. This is sigificant because copper wire links top out at about 20 Gbps. With the patents, Intel may have locked up business rights to the technology. While this stuff is very important for low-latency interprocessor communications in the hundred-processor servers which will soon be common, it's more likely to have immediate use in fiber-optic communications systems and the story speculates that Intel may finally be on the verge of the first big successful market its found outside of microprocessors since the old DRAM days.
