Outdoor Optical Fiber Cable IEC60794 Standard Loose Tube Armoured
Singlemode G652D Cable
Definition
The fibers, are positioned in a loose tube made of a high modulus
plastic. The tubes are filled with a water-resistant filling
compound. A steel wire, sometimes sheathed with polyethylene (PE)
for cable with high fiber count, locates in the center of core as a
metallic strength member. Tubes (and fillers) are stranded around
the strength member into a compact and circular cable core. The
cable core is filled with the filling compound to protect it from
water ingress, over which a thin PE inner sheath is applied. After
the PSP is longitudinally applied over the inner sheath, the cable
is completed with a PE outer sheath.
Characteristics
· Good mechanical and temperature performance
· High strength loose tube that is hydrolysis resistant
· Special tube filling compound ensure a critical protection of
fiber
· Crush resistance and flexibility
· The following measures are taken to ensure the cable watertight:
· Steel wire used as the central strength member
· Loose tube filling compound and 100% cable core filling
· APL moisture barrier
· PSP enhancing moisture-proof
· Water-blocking material
