The optical feber unit is positioned in the centre.Two parallel Fiber Reinforced Plastics(FRP)are placed at the two sides.
Then the cable is completed with a black or color LSZH sheath.
Characteristic:
Special low-bend-sensitivity fiber provides high bandwidth and excellent communication transmission property;
Two parallel FRP strength member ensure good performance of crush resistance to protect the fiber;
Simple structure,light weight and high practicability;
Novel flute design,easily strip and splice,simplify the installation and maintenance
Low smoke,zero halogen and flame retardant sheath.
