Fiber optic cable GYTY53

GYTY53 fiber optic cable is used for direct buried underground, it suit for long distance and LAN fiber communications, we supply both the single mode GYTY53 cable and multimode GYTY53 cables.

GYTY53 fiber cable is stranded loose tube structure with steel tape double sheaths, the loose tube stranding technology make the fibers have good secondary excess length and allow the fibers free movement in the tube ,which keeps the fiber stress-free while the cable is subjected to longitudinal stress. GYTY53 cable is steel tape armored and double PE sheath providing excellent crush resistance and rodent resistance. Metal strength member provides excellent strain performance.GYTY53 is available from 2 cores to 144 cores.

  1. Cable Specification
    1. Sheath Marking
    2. The color of marking is natural, but if the remarking is necessary, the yellow color marking shall be printed newly on a different position. The marking interval is 1 meter.
    3. An occasional unclear of length marking is permitted if both of the neighboring markings are clear.
    4. The both cable ends are sealed with heat shrinkable end caps to prevent water ingres. Ends A is red, and ends B is green.
    5. Fiber Color Indentification
Fibers colors marked according to Full Color Identification, the colors shall be chosen from the colors in the following sheet. Natrual is allowed if no affection to the identification.

  1. Loose tube
Loose tubes color identification used in cable is Indicatory Color Indentification.When faced to the cables ends A, the number is increased by the clockwise direction, and the number of loose tubes and the colors shall conform to the following sheet. If loose tubes are not enough, using fillers instead, and the fillers are all white.
