Mechanical properties of optical cables

4.3.4.1 The mechanical properties of optical cables should include the stretching, flattening, and bending of the cables.

4.3.4.2 The tensile and flattening forces that the optical cable is allowed to withstand shall comply with the provisions of Table 4.

Table 4 Allowable tensile and compressive forces for optical cables

model	Allowable tensile force (small value)		Allow flattening force (small value)
	FST (N)	FLT(N)	FSC(N/100mm)	FLC(N/100mm)
MGTS	3000	1200	2000	600
Note: FST - Transient tensile force; FLT - Long term tensile strength; FSC temporary flattening force; FLC - Long term flattening force.

4.3.4.3 The minimum allowable bending radius for optical cables is expressed as a multiple of the outer diameter D of the cable, and it should comply with the provisions of Table 5.

Table 5 Minimum allowable bending radius for optical cables

Static bending	10D
Dynamic bending	20D

Environmental performance of optical cables

The environmental performance of optical cables should include attenuation temperature characteristics, drip performance, water permeability, flame retardancy, and sheath integrity.

4.3.5.1 Applicable temperature range and its attenuation temperature characteristics

The applicable temperature range of optical cables and the allowable temperature attenuation of optical fibers relative to 20 ℃ shall comply with the provisions of Table 6.

Table 6 Applicable Temperature and Allowable Temperature Additional Attenuation of Optical Fiber Cables

Applicable temperature ℃	Allow additional attenuation of dB/km for optical fibers
-30～+60	single-mode fiber	multimode fiber
-30～+60	≤0.13	≤0.2

4.3.5.2 Drip performance

After 24 hours in an environment with a temperature of 70 ℃, the optical cable should have no dripping of filling or coating compounds.

4.3.5.3 Water permeability performance

When a water head of 1m is applied to the entire cross-section of the optical cable, the cable should be able to prevent longitudinal water seepage. (The steel wire armor layer may not be tested)

4.3.5.4 Flame retardant performance

It should comply with the provisions of 4.2 and 4.3 in MT/T386-2011.

4.3.5.5 Sheath integrity

The integrity of the plastic protective layer of the optical cable should be inspected by spark test, with a test voltage of AC 15kV.

4.3.5.6 Robustness of Signs

The markings on the optical cable sheath should be clear and firmly adhered to the sheath, and should still be recognizable after wiping test according to 6.6.
