What Our Customers Say

Trusted by transmission system operators, distribution utilities, and engineering firms

GMARK OPTICS supplied our 200km OPGW project with 48‑core fibre. The hardware was well‑packaged and the technical documentation was excellent. Splicing went flawlessly.

HS

Henk Smit

Grid Operations, TenneT

The ADSS cables we purchased for rural electrification have been in service for two years now. No signal degradation, even after severe storms. Highly reliable.

AK

Anna Kowalski

Project Manager, E.ON Distribution

Their distribution switch helped us upgrade our feeder protection. Low latency and robust against EMI – exactly what we needed for our substation automation.
