Our Story
Established with the independent brand GUANGYAN, focused on fiber optic communication instruments.
Grew from fusion splicers to a full 14-category range: OTDR, OPM, VFL, multimeters and more.
ISO9001/CE/FCC/RoHS certified; exports across Americas, Europe, Africa, Middle East and Southeast Asia.
Low-MOQ OEM, all-in-one instruments and a Red Dot-nominated VFL, building a value-driven global brand.
What we make
Fusion splicers, OTDR, optical power meters and visual fault locators are designed, assembled and tested in the same Shenzhen building, which is how we keep OEM minimums at 10 units and answer technical questions without routing them through a supplier.
