Karakteristike vanjskog optičkog kabela

Postoje mnoge klasifikacije optičkih kablova. Vanjski optički kablovi, kao što i samo ime govori, su generalno pogodni za vanjsku upotrebu. Dakle, koje su posebne karakteristike optičkih kablova na otvorenom? Pogledajmo.

1. Vanjski optički kablovi imaju visoku vlačnu čvrstoću, debeo i težak zaštitni sloj, i obično su oklopni (to je, obloženi metalom). Vanjski optički kablovi uglavnom su pogodni za međusobno povezivanje zgrada i udaljenih mreža. Općenito govoreći, vanjski optički kablovi samo su punila, jačanje članova, odabiru se omotači i drugi materijali. Na primjer, kada je vanjski optički kabel direktno zakopan, treba koristiti oklopljeni optički kabl. Kad je iznad glave, an optical cable with a black plastic outer sheath with two or more reinforcing ribs can be used.

2 Because the outdoor optical cable is used outdoors, it must have a waterproof function. Generalno, the outer sheath used is made of PE material, and its internal structure is generally divided into a central tube structure and a layered structure. From the naked eye, the indoor and outdoor jackets are generally yellow or orange PVC materials, and the outdoor ones are black PE jackets. Different from the model, the outdoor jacket generally has the word GY.

3. Outdoor optical cable: The outer packaging is thick, with some mechanical characteristics such as pressure resistance, corrosion resistance, and tensile strength. Outdoor optical cable is a communication line that completes the transmission of optical signals. The cable core is composed of a certain number of optical fibers in a certain manner, and is covered with a sheath, and some are also covered with an outer sheath. Outdoor optical cables are mainly composed of optical fibers (thin glass filaments like hair), plastic maintenance sleeves and plastic sheaths. There are no metals such as gold, silver, copper and aluminum in the optical cables.
