Description
Introduction:
Self-supporting FTTH drop cable is constructed with one or two single-mode fiber (G.657A1). The cable is protected by a dielectric strength member made of fiberglass reinforced plastic (FRP), steel wire and a LSZH outer jacket. Designed for outdoor installation, the cable is well suited for connections between the dome closure and small dwelling unit/warehouse and independent villas.
Characteristics
Self-supporting structure, light weight, easy to install
Special low-bend-sensitivity fiber provides high bandwidth and excellent communication transmission property
Steel wire as additional strength member has high tensile strength
Two parallel FRP strength members ensure good performance of crush resistance to protect the fiber
Simple structure, light weight and high practicability
Fibers count is 1-12 cores, can be other fiber cores upon request.
Novel flute design, easily strip and splice, simplify the installation and maintenance
Durable and flame retardant LSZH sheath, low smoke zero halogen
