MIL-PRF-85045/18C
Long-term minimum bend diameter: Sixteen times the OFCC outer diameter.
Tensile loading: >270 N
Dynamic bend tensile load: 90 N minimum
Jacket material: The OFCC jacket shall be composed of a low halogen, low smoke, low toxicity polymer
material.
Finished cable:
Dimensions and configuration: See figure 2. Four OFCC units shall be helically laid over the central member
with a maximum lay of 25 cm. The minimum outer jacket thickness shall be not less than 1.0 mm (establishes
compatibility with termination and penetration devices).
NOTE:
OFCC Optical fiber cable component
1.
FIGURE 2. Four-OFCC fiber optic cable.
Number of fibers: 4 (one per OFCC)
Concentricity: >0.8
Mass per unit length: <100 kg/km
Jacket material: The overall jacket shall be composed of a low halogen, low smoke, low toxicity polymer
material.
Short-term minimum bend diameter: Eight times the cable outer diameter. (The short-term minimum bend
diameter is to be used in all environmental and mechanical tests which specify a cable minimum bend diameter.)
Long-term minimum bend diameter: Sixteen times the cable outer diameter.
Minimum continuous length: The minimum continuous length of all cables shall be not less than 0.5 km. If
lengths less than 0.5 km are specified in the purchase order, a conformance inspection shall be performed on test
specimens not less than 0.5 km in length from which the purchase order lengths are cut.
Cable jacket color: Shall be black or blue.
