Characteristics
Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special water-blocking yarns ensure a critical protection of fibre in loose tube
Specially designed compact structure is good at preventing loose tubes from shrinking
PE sheath protects cable from ultraviolet radiation
The following measures are taken to ensure the cable watertight:
-Single Fibre Reinforced Plastic as the central strength member
-Special water-blocking yarn in loose tube
-Water-blocking yarn around the loose tube and central strength member
-Water-blocking tape around the cable core
-APL moisture barrier

Note:
a. Suffix Xn denotes fibre type
b. The colour arrangements of fibre and tube are specified in the colour identification table
c. The cable shouldn‘t store in outdoor environment more than 6 months in order to keep the cable reel good state
