bda connectivity - Fibre Optic Cables for High-Performance Data Transmission
Fibre optic cables have emerged as a crucial medium for high-performance data transmission, especially in applications where conventional twisted-pair or coaxial cables fall short in providing adequate bandwidth, extension, or protection against electromagnetic interference. These cables often replace copper-based systems due to their superior capabilities. The construction of fibre optic cables involves coating optical fibres with a secondary protection layer, and they are typically classified based on the type of core used. Core types include loose buffer tubes, tight buffer (semi-tight buffer), and multifibre loose buffer tubes, which are typically filled with water-repellent gel to enhance durability and reliability. Fibre optic cables are indispensable in modern data communication infrastructures, offering enhanced data carrying capacity and robustness, crucial for evolving technological and data transmission demands.
For an increasing amount of data transmission applications conventional media such as twisted-pair or coaxial cables do not longer meet the requirements of bandwidth, extension, or safety against electromagnetic disturbances. Fibre optic cables have stepped in taking the role of copper based data transmission cabling systems. Often, several fiber optic cables are bundled.
The Fibres:
Optic fibres are classified by different criteria:
- Fibre construction: There are step index and graded index fibres.
- Wave extension: Multi-mode and single-mode fibres are distinguished.
- Raw materials: Quartz glass or plastics (PMMA).
The Cores:
Before the optical fibres can be processed to practical cable constructions they need to be coated with a secondary protection layer. There are three different types of cores: loose buffer tubes, tight buffer (semi tight buffer) and multifibre loose buffer tubes. Multifibre buffer tubes are filled with water repellant gel.
