Structure of typical mine flame-retardant integrated optic cable is to put single mode or multi mode fiber into loose tube which is made of high modulus, and waterproof compound is filled in it. Center of the cable core is a phosphating steel wire. Loose tube (or filling rope and signal wire) is stranded into compact and round cable core around central strengthen member. Gap in cable core is filled of waterproof material. Covered of PE jacket and blue PVC jacket is finished cable.
