About
Us
A Shenzhen-based fiber optic component supplier focused on practical specification matching.
KernsTech supports customers sourcing passive fiber optic components for demanding optical systems. Our portfolio covers standard and custom configurations across six core product families.
Our sales process follows a simple buying workflow: find the product family → narrow the specification → review the datasheet → send a structured RFQ.
What we supply
Six core component families.
01Optical Isolators — PM, SM, mini and high-power configurations.
02Optical Circulators — standard, PM and higher-power application options.
03WDM & Filters — fused, filter-based, PM, CWDM, DWDM and related wavelength devices.
04Couplers & Polarization — fused couplers, polarizers, PBS/PBC, mirrors and polarization components.
05Fiber Laser Components — pump combiners, signal combiners, mode-field adapters, cladding light strippers and related components.
06Mini & Hybrid Devices — compact and integrated multi-function passive components.
Applications
Components for real optical systems.
Typical application routes on the site include fiber lasers, optical amplifiers, fiber sensing, telecommunications and laboratory research. When the application is known, it becomes part of the RFQ so the product selection can be reviewed in context.
Start with the specification you know.
Use Product Finder or send a structured RFQ for engineering review.
