From a single workshop to a three-country footprint

DYS Fiber Optic was founded in 2009 in Huizhou, Guangdong, at the start of China's last great fiber buildout — and from the start we focused on the full fiber stack, not just cable.

We built our first optical cable line in 2013 and added MPO/MTP capability in 2014 — the same year we were designated a National High-Tech Enterprise. That early breadth set our defining capability: doing connectivity end to end under one roof.
