Description Product Construction Features Specification

The ﬁbers, 250μm, 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 ﬁ ber 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 PSP is longitudinally applied over the cable core, witch is ﬁlled with the ﬁlling compound to protect it from water ingress. Then, the cable is completed with a PE sheath.

Good mechanical and temperature performance.
High strength loose tube that is hydrolysis resistant.
Special tube ﬁlling compound ensure a critical protection of ﬁber.
Special designed compact structure is good at preventing loose tube from shrinking.
Crush resistance and ﬂexibility.
PE sheath protects cable from ultraviolet radiation
The following measures are taken to ensure the cable watertight:
Steel wire used as the central strength member Loose tube ﬁlling compound
100% cable core ﬁlling
PSP enhancing moisture-proof
Application:duct/aerial/direct buride

Accurate process control ensuring good mechanical and temperature performances,
The material of loose tubes with good hydrolysis resistance and relatively high strength Tube filling compound providing the key protection for fibres,
Using small-sized B6a2 fibres with good micro and macro bending performance,
Comply with IEC60794-3-11(2007): Optical fibre cables- Part 3-11,
Water resistance of optical cable is ensured by the following measures: Special water-blocking compound filled in loose tubes,
Laminated aluminum tape armorCable filling compound ensuring longitudinal water resistance,
