Eoptolink Technology Inc., Ltd. Tech Stack

High-speed optical transceiver manufacturer for datacenter and telecom infrastructure

Telecommunications Chengdu, Sichuan 5,001–10,000 employees Founded 1998 Public Company

Eoptolink manufactures optical transceivers (100G through 1.6T) for datacenters, telecom operators, and equipment vendors. The tech stack—Cadence, FPGA, DSP, Zemax, Lumerical, C/C++, and embedded protocols (PCIe, Ethernet, I2C)—reflects a hardware-first, simulation-heavy design process. Active projects center on silicon photonics, thermal management, and test automation; hiring has decelerated but remains concentrated in engineering (24 roles), signaling focus on design maturity and manufacturing efficiency rather than headcount expansion.
