U-D(ZN)H Eca Unarmoured Fiber Optic Cable
Unarmoured central loose tube fiber optic cable with glass yarn reinforcement, thixotropic jelly filling and a UV-stabilized LSZH-FR sheath. The Eca classification is documented in DoP UPCOM-103 and report ERA-22-051.
Technical specifications
Select the fiber count and transmission grade for your link, then confirm the ordered construction and its CPR documentation. This cable uses a jelly-filled PC+PBT tube; it is not the dry-tube B2ca construction.
