Fibertronics is proud to offer custom cable assemblies featuring the new US Conec HEC-DC™ Hardened Connector. As an approved partner, we provide customers with professionally assembled and tested HEC-DC cable solutions for demanding outdoor, industrial, telecommunications, and military applications.
HEC stands for Harsh Environment Connector. Designed for next-generation outside plant (OSP) networks, the HEC-DC combines a compact footprint with IP68 environmental protection, making it ideal for high-density deployments where reliability and ease of installation are critical.
The HEC-DC introduces a new approach to hardened connectivity by combining high optical performance with an intuitive push-pull installation.
With a housing diameter of only 19 mm, the HEC-DC requires significantly less space than traditional hardened connectors. This enables:
The integrated DirectConec™ push-pull mechanism allows installers to connect and remove the connector quickly, with no tools required.
Designed for demanding outdoor deployments, the HEC-DC provides:
Fibertronics offers custom HEC-DC cable assemblies configured with your choice of connector interface, including:

Assemblies are available in a wide variety of fiber types and custom lengths to meet your project requirements. Cable options include round cables with 4.0mm – 6.5mm outer diameter, as well as a variety of flat drop cables.
To maximize deployment flexibility, the HEC-DC connector system supports both bulkhead and inline adapters, allowing it to integrate seamlessly into new or existing fiber optic infrastructure.

Available with US Conec Elite® MT ferrules, the HEC-DC delivers the low insertion loss and high reliability required for today's high-speed fiber networks.
HEC-DC cable assemblies are well suited for a wide range of demanding applications, including:
Beyond cable assemblies, more supporting products for the HEC-DC ecosystem are Coming Soon:
Cleaning tools, polishing supplies, and testing equipment for HEC-DC connectors.
HEC-DC compatible wall-mount enclosures for outdoor termination points.
Closures pre-engineered for the HEC-DC connector line.
Termination hardware designed for HEC-DC deployments in the field.
