InArmor+ FiberGlass DJ FiberGlass yarns Double Jacket (DJ)

A dielectric armored cable for applications where electrical conductors are in the same conduit system. It is a cost-effective solution for crowded urban conduits with rodent problems.


Central strength member — fiberglass dielectric rod


Optical fiber


PBT optical tubes filled with water-blocking gel


Water-swellable yarns


Inner jacket


Fiberglass yarns


Polymer jacketing





All-dielectric design

Fiberglass yarns prevent damage by rodents

InArmor+ FiberGlass DJ is a multi-tube cable with fiberglass yarns and double jacket. It is an all-dielectric design that features UV-resistance and moderate rodent protection.

This cable can be mainly:

  • Pulled into underground ducts and sewer pipes
  • Installed along bridges, tunnels and other structures
  • Installed into indoor/outdoor cable conduits and trays
  • Aerial lashed

Typically, InArmor+ FiberGlass DJ consists of a stranded core with a central strength member (FRP) and PBT loose tubes filled with water-blocking gel. Optical fibers (up to 144) are placed in loose tubes. The stranded core is fixed by water-swellable yarns. Fiberglass yarns are laid over an inner jacket.

InArmor+ FiberGlass DJ’s maximum rated design tension can reach up to 607 lb and resistance to crushing load starts from 126 lb/in. It has a wide range of operating temperatures from -40°F to +158°F and installation temperatures from -22°F to +158°F (operating temperature range can be increased on request).
