G.655

What is G.655 fiber grade？

The G.655 fiber is a single mode fiber standard for optical communications designed to minimize dispersion and support long-distance transmission. It has a core diameter of 9 μm and a cladding diameter of 125 μm.

What are the Main Features of the G.655 Fiber？

Non-Zero Dispersion Shifted (NZDSF): G.655 fiber is designed to have a non-zero dispersion shift characteristic. This means that it shifts the dispersion value of the signal from zero (around a specific wavelength) to other wavelengths. This feature helps reduce nonlinear effects and enables better transmission performance over long distances.

Low dispersion: G.655 fiber exhibits low chromatic dispersion, which refers to the spreading of different wavelengths of light as they travel through the fiber. By minimizing dispersion, G.655 fiber allows for higher data transmission rates and better signal quality.

Wide bandwidth: G.655 fiber provides a wide bandwidth, allowing for the transmission of multiple wavelengths simultaneously. This characteristic is particularly useful in Dense Wavelength Division Multiplexing (DWDM) systems, where multiple signals are combined and transmitted over a single fiber.

Long-distance transmission: G.655 fiber is optimized for long-haul transmission. It offers low attenuation, which means that the signal strength can be maintained over longer distances without significant loss. This makes it suitable for applications such as transoceanic and intercontinental communication links.

Compatibility: G.655 fiber is compatible with other standard single-mode fibers, making it easy to integrate into existing fiber optic networks and equipment. It can be used alongside other fiber types without compatibility issues.

High-speed data transmission: G.655 fiber supports high-speed data transmission, enabling the transfer of large volumes of data over long distances. It is suitable for applications that require high bandwidth and fast data rates, such as video streaming, cloud services, and data-intensive enterprise networks.

What are the Different Types of G.655 Single Mode Optical Fibers?

The main types of G.655 single-mode optical fibers include:

G.655.D: G.655.D fiber is the most common type of G.655 fiber. It has the minimum dispersion value among G.655 fibers. G.655.D fiber is optimized for long-haul transmission and is suitable for applications that require high-speed and high-capacity data transmission over long distances. It is commonly used in transoceanic and intercontinental communication links.

G.655.E: G.655.E fiber is an improved version of G.655.D. It has further reduced dispersion values, making it suitable for even longer transmission distances and higher data transmission rates. G.655.E fiber offers enhanced performance compared to G.655.D and is used in applications that demand extended reach and higher capacities.

What is the Application of G.655 fiber？

Here are some common applications of G.655 fiber:

Long-Distance Optical Networks: G.655 fiber is primarily used in long-haul optical networks that require transmission over significant distances, such as transoceanic and transcontinental communication links. Its low dispersion characteristics allow for extended reach and high data transmission rates.

Dense Wavelength Division Multiplexing (DWDM) Systems: G.655 fiber is well-suited for DWDM systems, which enable multiple wavelengths of light to be transmitted simultaneously over a single fiber. Its low dispersion properties help maintain signal integrity and support the multiplexing of numerous high-capacity data channels.

Regional and Metropolitan Networks: G.655 fiber is deployed in regional and metropolitan networks that span a large geographic area, connecting different cities and regions. It provides reliable and high-bandwidth connectivity for data-intensive applications, including video streaming, cloud services, and enterprise communication.
