Description
FTTH Single-Armored outdoor duct drop cable, which is also called conduit fiber cable or underground fiber cable, is usually implemented by placing it inside underground ducts, and the
ducts are normally buried in the ground. To construct the cable, a bow-type FTTH indoor drop cable is placed in the middle of the cable. In order to suit for underground duct installation, a water – blocking tape and an aluminum armored tube cover the 2x3mm drop cable. Finally, a durable polyethylene (PE) jacket is added to create a round cable cross – section and lend added protection to the cable core.
Feature
- Soft and flexible, good bending performance
- Water-proof tape prevent the ingression of water into the cable
- AL-plastic tape makes the cable crush resistant and moisture proof
- FRP strength member improves the tensile strength, LSZH flame-retardant inner and outer jacket has good flame-retardant performance
- Special low-bend-sensitivity fiber provides high bandwidth and excellent communication transmission property
- Simple structure, light weight and high practicability
- Novel flute design, easily strip and splice, simplify the installation and maintenance
