MIL-PRF-85045/20B
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.
OFCC color:
Slate (MIL-PRF-49291/6 fiber)
Yellow (MIL-PRF-49291/7 fiber)
OFCC marking: Each OFCC shall be uniquely marked with a number between 1 and 36. The form of the
marking shall be the printed spelling of the number, followed by a dash, followed by the printed Arabic numeral.
The marking shall be applied and repeated every 0.10 m (4 inches) along the OFCC jacket. OFCC number 1 shall
be located in the innermost ring of OFCCs. OFCCs shall be consecutively numbered starting with those in the
innermost ring (1 through 6), then those in the middle ring (7 through 18), and finally those in the outer most ring
(19 through 36). OFCCs numbered 1, 7, and 19 shall be located along approximately the same radial line within the
cable.
Finished cable:
Dimensions and configuration: See figure 2. Thirty-six OFCC units shall be helically layered over the central
member. The minimum outer jacket thickness shall be not less than 1.9 mm (establishes compatibility with
termination and penetration devices).
