Outdoor Fiber Cable Overview
Overview
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for fiber-optic communication in different applications, for example long-distance telecommunication or providing a high-speed data connection between different parts of a building. Hondao offer various of fiber optical cable .
PACKING AND DRUM
1. The cable is wound on a non-returnable wooden drum. Both ends of cable are securely fastened to drum and sealed with a shrinkable cap to prevent ingress of moisture. The following information shall be marked on the outer sheath of the cable at an interval of about 1 meter.
- Cabletype and number of optical fiber
- Manufacturername
- Month and Year of Manufacture
- Cable length
The sequential number of the cable length shall be marked on the outer sheath of the cable at an interval of 1meter ± 1%.
2. Drum marking, Each side of every wooden drum shall be permanently marked in a minimum of 2.5~3 cm high lettering with following:
- Manufacture name and logo
- Cable length
- Cable type and number of fibers
- Roll way
- Gross and net weigh
