The structure of the standard figure-eight self-supporting central tube optical cable is that single-mode or multi-mode optical fibers are sheathed in a loose tube made of high modulus plastic, and the tube is filled with a water-blocking compound. The center of the cable core is the loose tube. The loose tube is coated with plastic (wrinkle) steel tape longitudinally. The water blocking tape between the steel tape and the loose tube ensures the compactness of the optical cable and the longitudinal water blocking and is placed parallel to the steel strand. Simultaneously squeeze the figure 8 sheath into a cable.

Immarkar tal-għant
Il-kulur tal-immarkar huwa abjad, imma jekk ir-rimarka hija meħtieġa, l-immarkar tal-kulur abjad għandu jkun stampat ġdid f'pożizzjoni differenti.
Mhux ċar li okkażjonalment mhux ċar it-tul ta 'l-immarkar jekk iż-żewġ immarkar tal-viċin huma ċari.
Iż-żewġt itruf tal-kejbil huma ssiġillati b'għatu tat-tarf li jinxtorbu bis-sħana biex jipprevjenu d-dħul tal-ilma.
