The fibers are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water resistant filling compound. The tube is wrapped with a layer of Kevlar. Between the Kevlar yarn and the loose tube water-blocking material is applied to keep the cable compact and watertight. The cable is completed with a polyethylene (PE) or AT sheath.

Fiber cable plus cables are coiled on bakelite, wooden, or ironwood drums. During transportation, the right tools should be used to avoid damaging the package and to handle them with ease.
Cables should be:
It is not allowed to have two lengths of cable in one drum, and both ends should be sealed. The two ends should be packed inside the drum, and a reserve length of cable not less than 3 meters should be provided.
The color of cable markings is white. The printing shall be carried out at intervals of 1 meter on the outer sheath of the cable. The legend for the outer sheath marking can be changed according to the user's requests.
Technically, yes. Wi-Fi is a way to connect devices within a network. However, without an internet source like fibre or LTE, your Wi-Fi network will not provide internet access.
Fibre is the fastest, most-reliable, most-advanced internet connection technology available on the market today. This technology is known as Fibre Optics. Optical Fibre cables are made up of tiny strands of glass fibres encased in a cable. These fibres are thinner than a strand of hair.
