  1. Introduction to ACC optical fiber

    • Definition and rationale:
      ACC fiber is an optical fiber structure based on all-dielectric composite materials. Its core and cladding are both made of dielectric materials, rather than the glass core and cladding with different refractive index that are common in traditional optical fibers. ACC optical fiber uses the difference in refractive index of dielectric materials to transmit optical signals.

      In ACC fiber, the optical signal is reflected inside the fiber through the change in the refractive index of the material and thus transmitted along the fiber. The design of this all-dielectric material avoids loss and dispersion of optical signals and provides low-loss and high-bandwidth transmission.

      Although ACC fiber has many potential advantages, it is currently still in the research and development stage. More work needs to be carried out in material design, preparation process and performance verification to achieve its commercialization and widespread application.

Advantages and features of ACC fiber

  1. Low loss characteristics:
    ACC optical fiber has low loss characteristics compared to traditional optical fiber. This is due to the following reasons:

    a. No metal wires: ACC optical fiber does not contain metal wires, thus eliminating the resistance loss in traditional optical fibers caused by metal wires. This enables ACC fiber to achieve lower transmission losses.

    b. No material absorption and scattering: ACC optical fiber uses all-dielectric composite materials. Compared with the glass material in traditional optical fibers, the core and cladding of ACC optical fiber are made of dielectric materials. This eliminates optical signal attenuation caused by material absorption and scattering, thereby reducing transmission losses.

    c. Optimized refractive index difference: The design of ACC fiber optimizes the refractive index difference of dielectric materials so that optical signals can be efficiently reflected inside the optical fiber, reducing the attenuation and energy loss of optical signals.

    The low loss characteristics enable ACC fiber to achieve longer distance transmission and more efficient optical signal transmission, providing higher transmission efficiency.

  2. High bandwidth capacity:
    ACC optical fiber has high bandwidth capacity and can support large-capacity data transmission and high-speed communication needs. Its features include:

    a. Optimized transmission performance: The design of ACC fiber can reduce dispersion effects and provide greater bandwidth capacity. It can support large-capacity data transmission applications such as high-speed data transmission, high-definition video streaming, cloud computing, and large-scale data centers.

    b. Low-delay transmission: Since ACC fiber has lower dispersion effect and loss, it can achieve shorter signal propagation time, thereby reducing transmission delay. This is critical for applications that require low latency, such as financial transactions and real-time data transfer.

    c. Future scalability: As a new material, ACC optical fiber has the potential to expand to higher bandwidth capacity in the future. As the demand for higher speeds and greater capacity continues to grow, ACC fiber may be able to meet future communication needs through further optimization of design and material selection.

    High bandwidth capacity makes ACC fiber optic an ideal choice to meet the growing data transmission needs and high-speed communication needs.

Preparation and structure of ACC optical fiber

Preparation Process:
Preparing ACC optical fiber involves the following main steps and processes:

a. Material selection: The preparation of ACC optical fiber requires the selection of appropriate dielectric materials to form the core and cladding. These materials are usually dielectric materials with different refractive indices, such as polymers, glasses, oxides, etc. The selection of materials should consider their optical properties, mechanical strength and feasibility of the preparation process.

b. Core structure design: The core structure design of ACC fiber is one of the key steps. By adjusting the geometry of the fiber core and the difference in material refractive index, efficient transmission of optical signals within the fiber can be achieved. Common core structures include single-mode and multi-mode cores, with specific designs depending on application requirements.

c. Preparation process: ACC optical fiber can be prepared using a variety of processes, such as drawing, deposition or stacking. Among them, the drawing method is a commonly used preparation process, which forms the structure of the optical fiber by heating and stretching prefabricated materials. During the preparation process, the temperature, stretching speed and degree of stretching of the material need to be controlled to obtain the required optical properties and structural characteristics.

Optical fiber structure:
The structural characteristics of ACC optical fiber usually include the following parts:

a. Core: The core is the central part of the ACC fiber and is used for the transmission of optical signals. It is made of dielectric materials and achieves the transmission and reflection of optical signals through differences in refractive index. The geometry and refractive index distribution of the fiber core have an important impact on the transmission performance and bandwidth of the optical fiber.

b. Cladding: The cladding is the outer layer of the fiber core and is used to limit the propagation of optical signals in the fiber core. It is also constructed of dielectric material and has a low refractive index to ensure total internal reflection of the optical signal inside the core. The design of the cladding helps reduce attenuation and dispersion of optical signals.

c. Jacket: The jacket is the outer layer used to protect the optical fiber, providing mechanical protection and environmental isolation. It is usually made of polymer material, which has good flexibility and durability.

The structure of ACC fiber can be adjusted and optimized according to specific application needs to achieve the required optical performance, transmission performance and durability. Continuous improvements in preparation processes and structural designs will promote the development and application of ACC optical fibers.
