Product Description / PRODUCT

The Mini central tubular air-blown cable is used to place the colored 2-24-core fiber in the bundle tube, and the outer skin is extruded into a high-density polyethylene outer sheath.

Product Features / PRODUCT

　　●Special composite loose tube to reduce the shrinkage of low temperature casing;

　　● Precise control of fiber optic length, stable performance of fiber optic cable;

　　●Unique process control to prevent wrinkling of the jacket during air blowing;

　　● High-density polyethylene outer sheath to increase the air blowing distance.

Mechanical properties / PRODUCT

project	Test reference standard		Test Results		Remarks
Stretch	IEC 60794-1-2-E1 (GB / T 7424.2-E-1)		Fiber strain (%)	Attachment attenuation (dB)	Short-term test pull force is the maximum pull force, long-term test pull force is 1/3 maximum pull force
			Short term ≤ 0.3 long term ≤ 0.1	Short-term: ≤0.1, no obvious strain after stress removal; long-term: no obvious
Flattening force		IEC 60794-1-2-E3 （GB/T 7424.2-E3）	Short-term flattening force: additional attenuation ≤0.05; long-term flattening force: no obvious; after stress removal, the fiber has no obvious residual additional attenuation, no visible cracking on the sheath surface		Short-term test pressure: 600N long-term test pressure: 200N
Repeated bending test		IEC 60794-1-2-E6 (GB / T 7424.2-E6)	After the test: the fiber has no obvious residual attachment attenuation; the sheath has no visible force visible cracking		Bending radius = 20 times the diameter of the micro cable
					Load = 15N
