What Source Photonics does
Source Photonics is a global manufacturer of optical transceivers and photonic components, founded in 1987 and headquartered in West Hills, California. The company designs and produces a comprehensive portfolio of optical connectivity products spanning from upstream components (TO-Cans, EML and DFB laser chips, BOSA, Optical Sub-Assemblies) to complete transceiver modules supporting data rates from 100G to 1.6T, organized across four product categories: data center transceivers, fixed broadband equipment, wireless broadband network, and optical transmission. Source Photonics is one of the top five manufacturers in the EML (electro-absorption modulated laser) market, which collectively hold approximately 80% of EML market revenue as of 2025, and serves hyperscale data center operators, fixed broadband carriers, wireless network operators, and telecom equipment manufacturers through direct sales offices across the US, China, Taiwan, and India.\n\nThe company's business model is hardware-based and sales-led, with revenue generated from sale of optical transceivers, TO-Cans, DFB/EML chips, BOSA components, optical subassemblies, and PON modules. Pricing is not publicly disclosed; customers engage direct sales for quotes. Manufacturing is anchored at the Chengdu and Shenzhen facilities in China, with optical chip production concentrated at the Jintan (Changzhou) base. The proprietary Source Lean Quality (SLQ) system supports lean manufacturing and world-class operational efficiency. Marketing and customer engagement are channeled through flagship industry events OFC and CIOE, a corporate website with technical documentation, and dedicated sales and technical support teams in each region.\n\nIn 2025, Source Photonics was acquired by Suzhou Dongshan Precision Manufacturing Co., Ltd. (Shenzhen: 002384.SZ) for approximately 5.9 billion yuan (~$810 million), and has been consolidated into the parent's financial statements since October 2025. By Q1 2026, Source Photonics accounted for more than half of Dongshan Precision's consolidated profit, and in June 2026 the parent's board approved a $1.2 billion investment to expand the subsidiary's optical chip and module production capacity. The company had previously raised a $90 million Series D funding round in December 2023.
