Layer twisting optical cable and center beam tube -type optical cable

2023-09-18 17:31:00

The difference between layer twisted optical cable and center beam tube -type optical cable,Introduction

Optical cables are used to transmit data over long distances using light as the signaling medium. They come in different designs, including layer twisted optical cables and center beam tube-type optical cables. In this article, we will discuss the differences between these two types of optical cables.


Layer Twisted Optical Cable

A layer twisted optical cable is a type of optical cable that has a twisted structure. The cable has a central core made of glass or plastic fiber that is surrounded by several layers of protective materials. The layers are twisted around the central core to create a helical structure that provides protection and support to the fiber.


The protective layers are made of materials such as polyethylene, polypropylene, and aramid fibers. These materials provide mechanical protection and help to prevent damage to the fiber during installation, handling, and operation.


The layer twisted design of this type of optical cable provides several advantages, including:


High Tensile Strength: The twisting of the protective layers around the central core provides the cable with high tensile strength. This makes it ideal for use in applications that require high tensile strength, such as aerial installations.


Good Flexibility: The twisting of the protective layers also provides the cable with good flexibility. This allows the cable to bend and conform to different shapes and contours without breaking.


Easy to Install: The layer twisted design makes the cable easy to install. The cable can be pulled through conduit or laid directly in the ground without the need for expensive and complicated installation equipment.


Center Beam Tube-type Optical Cable

A center beam tube-type optical cable is a type of optical cable that has a central tube made of plastic or steel. The tube contains several fiber optic cables that are protected by a layer of gel or water-blocking material. The tube is then surrounded by layers of protective materials, such as polyethylene and aramid fibers.


The center beam tube design of this type of optical cable provides several advantages, including:


High Protection: The central tube provides high protection to the fiber optic cables. This makes the cable ideal for use in harsh environments, such as underground installations and areas with high traffic or construction activity.


Easy to Repair: The center beam tube design makes it easy to repair the cable in case of damage or breakage. The damaged section of the cable can be cut and replaced without affecting the rest of the cable.


Long Service Life: The center beam tube design provides the cable with a long service life. The cable can withstand harsh environments and extreme temperatures, ensuring reliable operation over a long period.


Differences between Layer Twisted Optical Cable and Center Beam Tube-type Optical Cable


Design

The layer twisted optical cable has a helical structure with protective layers twisted around the central core. The center beam tube-type optical cable has a central tube that contains several fiber optic cables protected by layers of gel or water-blocking material.


Tensile Strength

The layer twisted optical cable has high tensile strength due to the twisting of the protective layers around the central core. The center beam tube-type optical cable also has high tensile strength due to the central tube design.


Flexibility

The layer twisted optical cable is more flexible than the center beam tube-type optical cable. The twisting of the protective layers around the central core provides the cable with good flexibility, allowing it to bend and conform to different shapes and contours. The center beam tube-type optical cable is less flexible due to the rigidity of the central tube.


Protection

The center beam tube-type optical cable provides higher protection to the fiber optic cables than the layer twisted optical cable. The central tube provides a high level of protection against damage from external factors, such as construction activity and environmental factors.
