Product Description

Products Description

Mini central tube type air-blown optical cable is to place colored 2-24 core optical fibers in the bundle tube, and extrude a layer of high-density polyethylene outer sheath.

 

 

Features

Special composite material loose tube, reducing the retraction of low temperature tube;

Precisely control the excess length of the optical fiber, and the performance of the optical cable is stable;

Unique process control to prevent sheath wrinkling during air blowing;

Outer sheath of high-density polyethylene to increase the air blowing distance.

Mechanical Behavior:

Item	Test reference standard			Test Results			Remark
Stretch	IEC 60794-1-2-E1 GB/T 7424.2-E1			Fiber strain%	Attachment attenuationdB	The short-term test pull is the maximum pull, The long-term test pull is 1/3 of the maximum pull
					Short term ≤0.3 Long-term ≤0.1		Short term: ≤0.1, No obvious strain after stress removal; Long term: none apparent
Flattening force			IEC 60794-1-2-E3 GB/T 7424.2-E3	Short-term crushing force: additional attenuation ≤0.05; Long-term crushing force: no obvious; After the stress is removed, the optical fiber has no obvious residual additional attenuation, No visible cracks on sheath surface			Short-term test pressure: 600N    Long-term test pressure: 200N
Bending repeatedly test			IEC 60794-1-2-E6 GB/T 7424.2-E6	After the test: the optical fiber has no obvious residual attachment attenuation; No visible cracks in sheath			Bending radius = 20 times the microcable diameter
