Fabless optical communication components supplier VI Systems GmbH of Berlin was granted three US patents for proprietary technology related to energy-efficient and compact high-speed optical interconnects. The patents are titled “Opto-electronic assembly for high speed transmission,” “Optoelectronic interconnect for high frequency data transmission at low power consumption,” and “Method for encoding and decoding of optical signals.” A 700- to 890-nm parallel optic transmitter testboard module for 4 x 25 Gb/s. “This is an important achievement for the company in a time when the optical link technology moves to 26 to 28 Gb/s in 2013 and the standardization work on 56 Gb/s per channel is going to be completed by the end of 2014. At these bit data rates a key requirement for the success is the realization of low cost, compact and energy-efficient integrated optical assemblies, including heat dissipation and cross-talk considerations,” VI Systems’ CEO Nikolay Ledentsov said.
