Shenzhen Tanlink Optics Co., Ltd

With its strategic and systematic R&D, key technologies for optoelectronic chips and mass production capabilities, Shenzhen Tanlink Optics Co., Ltd. has become a leading manufacturer of optoelectronic devices for optical communications.

Founded in 2012 and based in Shenzhen and Wuhan, Shenzhen Tanlink merged with Wuhan Tri-light in December 2018, providing a boost to the growth of its business scale and R&D strength. In May 2022, Wuhan Tanlink Precision Communications Co., Ltd. was established to enhance the production capacity of 400G QSFP-DD optical transceivers and added 800G optical devices.

The company has been focusing on COB technology research since its establishment in 2012, and is one of the first companies in China to engage in COB R&D and production. We provide customization service for multi-channel optical modules (25G/40G/100G QSFP28/400G transceivers) based on COB technology, a full range of optical engine products such as QSFP-DD/HDMI/USB/Mini-SAS/CXP2 AOC optical cable, and ODM customization service for COB products.

We focus on developing high speed optical modules with high capacity, small size, low power consumption and low cost.
