Fiber Optic FTTH Drop Cable for making Patch cord with SC connector
Product Description
The structure of butterfly fiber cable (leather wire cable) is to
integrate small bending radius single mode fiber and two
symmetrical reinforcement in flame retardant sheath. The strength
member can be steel wire, KFRP or GFRP, and the sheath material can be flame retardant PVC
or low smoke halogen free fuel , and the sheath color can be white,
black or user. Other colors to be asked. The sheath structure which
is easy to tear and the allowable bending radius makes the
installation of optical cable convenient. The fiber optic cable can
use G.657 fiber, the fiber has excellent bending performance, small
bending radius can be less than 15mm, especially suitable for
indoor cabling with small turning radius, such as wall corner,
indoor panel.
Optical fiber:
We adopt the best Yangtze G657A flexural optical fiber at present.
The loss meet the requirements of the national standard. The
bending radius is only 7.5mm, the bending loss is small, and the
bending life is long.(The G652 fiber used by online merchants is
not suitable for FTTH for dry optical fiber) The cost of flexural
optical fiber is about double of ordinary optical fiber. Yangtze,
beacon fire, Tong Ding and other major brands also use G657A2
optical fibe
Sheath:
the new high environmental PVC rubber particles. Cold resistant,
heat-resistant and corrosion resistant. The luster is strong,
beautiful and practical.
Steel wire:
the real use of reinforced phosphating steel wire. Surface
phosphating treatment, antirust, corrosion resistance, tensile
strength can reach 2500mpa, some manufacturers of copper clad iron
strength is only about 700MPa, far below the national standard.
Each reel of cable passed the OTDR test before shipping
This product adopts anti bending G657-A2 core, and the loss reaches
the standard. The bending radius is up to 7.5mm, and the bending
life is longer. More suitable for indoor / outdoor complex wiring
environment! The bending loss is much less than that of other
cores, and is perfectly compatible.
Characteristics
Special low-bend-sensitivity fiber provides high bandwidth and
excellent communication transmission property;
Two parallel FRP strength members 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 smokeand flame retardant sheath.

Comparasion of strength member material:
If the strength member are made by copper clad iron,after a period
of time in air, it is easy to oxidize, broken and has poor tensile
strength.
But we use the strengthened steel wire ,it is treated by
phosphating, and is resistant to embroidery and corrosion
resistance. The strength is 5 times that of copper coated iron.
Made to patchcord.
