What is air blown micro cable

Background Whether it is a trunk line or a metropolitan area network, underground pipe hole resources are very tight. Compared with ordinary cables, the use of air-blown micro-cables can save nearly 50% of the resources in pipe holes. The typical structure of the air-blown micro-cable system is mother pipe-micro-pipe-micro-cable. The mother pipe can be placed in the concrete pipe hole, and new routing construction can also be carried out. In the already laid HDPE or PVC parent tube, or pre-lay the parent tube and micro-tube on the newly-built optical cable route, it can be blown through the tube or blown...

What is Indoor Optical Cable

What is Indoor Optical Cable Indoor optical cables are optical cables laid in buildings and are mainly used for communication equipment, computers, switches and end-user devices in buildings to transmit information. What is Indoor Optical Cable Introduction Indoor optical cables are classified according to the use environment of optical cables, as opposed to outdoor optical cables.Indoor optical cable is a cable formed by optical fiber (optical transmission carrier) through a certain process. It is mainly composed of optical fiber (glass filament as thin as hair), plastic protective sleeve and plastic outer skin. There is no metal such as gold, silver,...

What is Outdoor Direct Buried Optical Fiber Cable

What is Outdoor Direct Buried Optical Fiber Cable Definition Direct buried optical fiber cable is a communication optical cable laying method. This kind of optical cable has steel tape or steel wire armor on the outside, and is directly buried in the ground. It requires the performance of resisting external mechanical damage and the performance of preventing soil corrosion. Direct buried optical fiber cable GYTA53 Structure Normally there are two or more layers of jacket structure to protect the cable core. The center uses metal or non-metallic reinforcement members, among which non-metallic reinforcement members are suitable for heavy mine areas....

What is fiber optic cable

What is fiber optic cable fiber optic cable Definition of fiber optic cable Optical fiber cable is manufactured to meet optical, mechanical or environmental performance specifications, it is a communication using one or more optical fibers placed in a sheath as the transmission medium and can be used individually or in groups cable assembly. Optical cables are mainly composed of optical fibers (glass filaments as thin as hair), plastic protective sleeves and plastic outer skins. There are no metals such as gold, silver, copper and aluminum in the optical cables, and generally have no recycling value. Optical cable is a...

What is FTTH drop cable

What is FTTH drop cable What is FTTH drop cable The sheathed FTTH drop optical cable is mostly single-core or double-core structure, and can also be made into a four-core structure. The cross section is in a figure-8 shape. The reinforcement is located in the center of the two circles. Metal or non-metallic structure can be used. . The optical fiber in the leather cable adopts G.657 small bending radius optical fiber, which can be laid with a bending radius of 20mm. Introduction of FTTH drop cable FTTH drop cable is commonly known as indoor hanging wiring cable. Under the...

How do submarine cables work?

How do submarine cables work? underwater submarine optical fiber cable Submarine optical cables are actually optical fibers, which use the propagation characteristics of light in optical fibers to transmit data. However, the submarine optical cable is not a simple optical fiber, it is actually a complex transmission system. The submarine optical cable system consists of two parts: underwater equipment and shore equipment. Underwater equipment It mainly includes optical cable, optical amplifier/repeater and underwater branch unit. What is the repeater used for? As we all know, despite the high speed and sufficient bandwidth of optical fiber, the signal transmission distance is...

Introduce in detail what is a submarine cable

Introduce in detail what is a submarine cable Background The Internet has become an indispensable part of our lives, and the submarine cable is the "central nerve" of the Internet. It carries more than 90% of the world's international voice and data transmission. Without it, the Internet is just a local area network. At present, there are more than 400 submarine optical cables in the world, with a total length of about 1.2 million kilometers, which is three times the distance from the earth to the moon. Only 5% of the international data transmission on the Internet relies on land...

Introduce in detail what is ADSS fiber optic cable

Introduce in detail what is ADSS fiber optic cable ADSS cable introduction ADSS cable introduction ADSS optical cable, All-dielectric Self-supporting Optical Cable (also known as all-dielectric self-supporting optical cable). An all-dielectric (metal-free) optical cable is independently hung on the inside of the power conductor along the transmission line frame (the position of the suspension is mainly determined by factors such as the electric field strength at the suspension place, ground distance, construction and maintenance convenience conditions, etc. Hanging below the power wire) to form an optical fiber communication network on the transmission line, this optical cable is called ADSS....
