IPtronics designs and markets high speed semiconductor laser drivers and transimpedance amplifiers used in parallel optical interconnect (POI) applications in supercomputer, server, storage, and router markets. IPtronics chipsets provide module vendors and system vendors with a high performance low cost solution outperforming that of direct competition and of electrical interconnect solutions. IPtronics’ laser-drivers/transimpedance amplifiers consume one quarter of the power compared to best known competitor, which in many applications answers to the pain of customers going green.

Sunstone first invested in IPtronics in 2008 as a series A investment. IPtronics was acquired by Mellanox® Technologies, Ltd. (NASDAQ: MLNX; TASE: MLNX) in July 2013.
