What’s The Main Difference Between Layer-stranded Optical Cable and Central Tube Optical Cable?

The main differences between Layer-Stranded Optical Cable and Central Tube Optical Cable lie in their cable structure and performance characteristics. Here’s a comparison of the two types:

Layer-Stranded Optical Cable
Structure: Layer-stranded optical cables have several layers of steel or aluminum wires stranded together, with optical fibers laid in the interstices between the wires
Flexibility: This design provides more strength and is more suitable for high tension applications.
Performance: Layer-stranded cables are currently the most used structure type of ribbon fiber optic cables

Central Tube Optical Cable
Structure: Central tube optical cables consist of a central tube, around which are laid steel wires or aluminum alloy wires. The optical fibers are then laid in the tube
Flexibility: This design allows for greater flexibility and provides more space for the optical fibers
Performance: Central tube optical cables have good lightweight, small diameter, and low cost characteristics, making them suitable for optical communication networks. However, it may be difficult to control the excess optical fiber length, and at extreme temperatures, fiber failure might occur

In summary, the choice between Layer-Stranded Optical Cable and Central Tube Optical Cable depends on the specific application and performance requirements. Layer-stranded cables are more suitable for high tension applications, while central tube cables offer greater flexibility and more space for optical fibers.
