    4.2.4.4 Fiber optic appearance and color

    The smooth surface of the circular sheath, the section without visual cracks, bubbles and defects such as trachoma. Sheath color is black.

    4.2.4.5 sheath logo and meter error

    The optical cable is a permanent sign on the sheath surface along the length direction, which does not affect any performance of the optical cable. When the printing direction is left to the right, the print is in the following cable. The distance between the beginning points of the adjacent signs is not less than 1m. The contents of the logo include the type of fiber optic cable products, the length of meter meter, the name of the manufacturer (or the code name) or (and) trademark and manufacturing year or batch number, etc. The mark is clear and is firmly adhered to the sheath. It is still recognizable after the wear test. Sign by meters in length deviations from 0 to 1%, in order to ensure the real length of not less than the length of the meter.

    4.2.4.6 packaging and transportation

    Fiber optic cable products are installed on the optical cable delivery plate, and the diameter of the core is not less than 20 times the diameter of the cable and is not less than 90mm. The product is also attached with appropriate protection, such as packing. Each disk has only one manufacturing length, and it has been marked on the optical cable tray and the packaging box: the manufacturer's name and product label, cable mark, cable length, gross weight (kg), manufacturing date and / or production batch number, and other signs to ensure the safety of storage and transportation.

    Cable transport and storage should pay attention: do not make the cable reel in flat position, no box cable tray shall be stacked; rolling rotating disc cable should be according to the direction of the arrow reel label, not long rolling; shall be subjected to collision, extrusion and any mechanical damage; to prevent damp and long time exposure; storage temperature should be controlled at -5 DEG +50 DEG C, if exceed the allowable temperature range should be inspected before delivery.
