The
Company
Precision components. Practical engineering support.
KernsTech is the international brand of Shenzhen Kanghao Technology Co., Ltd., supplying passive fiber optic components for fiber lasers, optical communication, fiber sensing, amplifiers and laboratory systems.
Our product range focuses on optical isolators, circulators, WDM & filters, couplers & polarization components, fiber-laser components, and mini & hybrid devices. Our product selection and documentation are organized around wavelength, power, fiber, configuration, connector and package.
From standard components to custom configurations, our goal is simple: help customers confirm the specification faster, review the technical fit, and move to a clear RFQ without unnecessary back-and-forth.

Quality & Reliability
Specification first
Partnership
Standard to customBuilt for engineers and B2B buyers.
KernsTech connects product families, parameter-driven selection, technical datasheets and RFQ details into one practical purchasing path.
Passive fiber optics
PM, high-power, mini, hybrid and custom passive components across six product families.
Search by parameters
Navigate by wavelength, power, fiber, package, configuration and connector—not only by product names.
Engineering before RFQ
Share your known parameters and application so the configuration can be reviewed before quotation.
Datasheet-led
Product pages connect directly to available technical documents to make specification comparison easier.
Standard to tailored
Non-standard wavelength, fiber, power, package or connector requirements can be submitted for review.
Direct contact
RFQs are structured around the details needed for technical confirmation and commercial follow-up.
Have a component requirement?
Send the wavelength, power, fiber, connector, quantity and application for review.
Product delivery presentation
Supplementary packaging imagery reinforces that KernsTech products are not only engineered and tested, but also prepared for consistent commercial delivery.
