• The unique fiber excess length control method provides the cable with excellent mechanical and environmental properties
• Very strict material and manufacturing control guarantees the cable can work stably for more than 30 years.
• Total cross-section water-resistant structure and Aluminium armor make cable have an excellent properties of moisture resistance
• Special jelly filled in the loose tube provides the fibers with critical protection
• The central member adopted corrosion resistant, high young's modulus FRP rod.
2. Cable Specification
2.1 Sheath marking
: Cable type
: 48 cores single-mode optical fiber(ITU-T Rec. G.652D)
: Mark of meters
*The marking is printed every 1 meter;
**”48SM” means ITU-T Rec. Low Water Peak (LWP) G.652 single mode optical fiber.
2.2 The color of marking is white, but if the remarking is necessary, the yellow color marking shall be printed newly on a different position.
2.3 An occasional unclear of length marking is permitted if both of the neighboring markings are clear;
2.4 The both cable ends are sealed with heat shrinkable end caps to prevent water ingress.
