# InnoLight Technology

> InnoLight Technology designs and manufactures the pluggable optical transceivers that turn electrical data into light inside data centers and across telecom networks. Founded in 2008 and based operationally in Suzhou, the company sells 25G through 1.6T modules, coherent optics, and mobile-network products to cloud operators, equipment makers, system integrators, and carriers. Its position is built on getting new speeds into standard, swappable form factors while controlling power, heat, reach, manufacturability, and cost at high volume.
