G657A1 indoor fiber optic drop cable with black color LSZH jacket
1 · Special low-bend-sensitivity fiber provides high bandwidth and excellent communication transmission property;
2· Two parallel FRP strength members ensure good performance of crush resistance to protect the fiber;
3· Single steel wire or massagers as the additional strength member ensures good performance of tensile strength;
4· Simple structure, light weight and high practicability;
5· Novel flute design, easily strip and splice, simplify the installation and maintenance;
6· Low smoke, zero halogen and flame retardant sheath.It protect environment,can resist the ultraviolet rays,and prevent dehisce.
FTTH (Fiber to The Home) is a kind of transmission cable used to connect directly to a home user or a business user. With no limits to its bandwidth, wavelength and transmission technology and being suitable for the application of various new services, FTTH cable is the best solution for the connection between the internet backbone to the user’s desktop.
Many domestic small factories modified electric-wires equipment to produce FTTH cable. They used unqualified fibers which is with very cheap price 3USD/KM to imitate G657 bend-resistant fiber, waste electric-wires and rubber slippers smashed as pvc raw material for the LSZH outer sheath. Those inferior cables will cause many problems such as short transmission distance, low bandwidth, intermittent signal and easy-to-crack of the cable jacket in several months, etc.
The optical fiber unit is positioned in the centre. Two parallel Fiber Reinforced Plastics (FRP) are placed at the two sides. A steel wire as the additional strength member is also applied. Then the cable is completed with a black or color LSZH sheath.
