GouMax Technology

What GouMax Technology does

GouMax Technology, Inc. is a Milpitas, California-based designer and manufacturer of high-end optical components and modules used primarily in fiber-optic test and measurement (T&M) and optical communications applications. The company was founded in 2015 by fiber-optics industry veterans and has operated as a privately held entity throughout its history; in May 2025, Tengjing Technology — an optical module supplier into Lumentum, Coherent, Innolight, and Accelink — acquired a 51% majority stake, making GouMax a majority-owned subsidiary. GouMax employs 11-50 people, maintains RoHS-compliant products, and holds US copyrights and trademarks.

The product portfolio centers on proprietary voltage-controlled tunable filter technology combined with in-house micro-optics, thin-film coating, interferometer, and spectrometer capabilities. Core offerings include tunable laser sources (TLS-1200, TLS-100), miniature optical spectrum analyzer (OSA) modules with SMSR analysis, multi-channel laser scan analyzer (LSA) power-meter modules (1/2/4/8 channels), voltage-controlled tunable optical filters, optical interleavers (UFP technology), and wavelength meters — complemented by precision optics, molded glass aspheric lenses, and fiber sub-assemblies. Differentiated performance specifications include sub-10 ms wavelength tracking, 70-80 dB dynamic range, 0.004 dB power stability, and no-moving-parts operation across the 1250-1680 nm range. Recent launches (TLS-100 in 2023, Smart Power Meter in 2024, High-Speed Wavelength Meter in 2026) suggest ongoing product investment.

GouMax operates a B2B enterprise go-to-market via direct US technical sales and a global distributor network spanning Canada, China, Taiwan, Israel, Thailand, and Turkey, supplemented by recurring OFC conference participation. Revenue is generated almost exclusively through hardware sales of modules and components, with custom/ODM solutions for defense and sensing applications. End customers include T&M equipment manufacturers, telecom laser and ITLA producers, DWDM/optical network builders, biomedical instrument makers, defense primes, and research institutions. Pricing is contact-based with no public disclosure, consistent with a small, specialized, enterprise-focused supplier.
