Due to the rapid development of telecommunication, fiber optic Cabinet, as one of the most important components has drawn more and more attention. Most people were quite familiar with the classification of single-mode fiber optic Cabinet and multimode fiber optic Cabinet. Today, I will present a new type of fiber optic Cabinet to you—greentelftth fiber optic Cabinet. Greentelftth fiber optic Cabinet is a kind of fiber optic Cabinet, which uses flexible stainless steel tube inside the outer jacket as the armor to protect the fiber glass inside. It remains all the features of standard fiber optic Cabinet, but it is much stronger. And it will not get damaged even if stepped by an adult and they are rodent-resistant. In the structure of the greentelftth fiber optic Cabinet, the outer sleeve offers protection against rodent, abrasion, twist, etc. It is usually made of plastic such as polyethylene. The next layer between the sleeve and the inner jacket is an armoring materials, such as kevlar, steel, aluminum foil, which is mainly to protect the fiber Cabinet from being stretched during installation. Next the ripcord, ripcords are usually used to splice the Cabinet to connectors or terminators. Then the inner jacket is a flame retardant material to support the inner fiber Cabinet bundle that is made up of strength members, fillers and other structures. The strength members are usually aramid yarn to support the whole fiber Cabinet. This structure is featured by an overall black medium density polyethylene jacket with ripcords.
