HDC Connector

Hardened Fusion Splice-On Connector

Fully Compatible OptiTap® Style Hardened Solution

The Swift HDC Connector provides the highest quality standards-based field-installable connector for hardened optical applications. This field-installable hardened solution is ideal for both new installations and emergency repairs and eliminates inventoried products in warehouses and on tech vehicles, reducing SKU’s and improving cash flow. The elimination of slack storage boxes reduces slack storage challenges and provides neatly organized cables on the pole that use only the cable you need.

5 applicable cables: 5.8 mm drop cable, 5.0 mm crop cable, 5.4 x 3.0 mm ROC drop cable, 8.1 x 4.5 mm SST drop cable

  • Environmentally robust to provide a reliable interface in the outside plant environment
  • Simplifies installation and maintenance in the FTTP(Fiber to the premises) network
  • Protects against extreme temperature, moisture, UV, chemical exposure and other harsh conditions
  • Provide cost savings by reducing wasted cable slack
  • Easily terminates in the field for onsite maintenance and performance-driven connections
