G.655

G.655 fiber grade is a special type of optical fiber defined by the International Telecommunication Union (ITU), which is mainly used for long-distance communication and high-bandwidth applications. It belongs to non-zero dispersion-shifted fiber (NZ-DSF), which has become an important part of modern communication networks with its unique optical properties and superior performance.

What is G.655 Fiber Grade

G.655 fiber grade is a single-mode fiber designed to reduce the dispersion effect, thereby maintaining the integrity of the signal during long-distance transmission. Its specific design enables the optical signal to maintain a relatively constant speed within a specific wavelength range when propagating in the optical fiber. This feature enables G.655 fiber grade to perform well in high data rates and long-distance transmission.

Features of G.655 Fiber Grade

Low dispersion rate: G.655 fiber grade has relatively low dispersion characteristics, which means that during the propagation of optical signals, optical signals of different wavelengths will not experience serious delay differences, thereby reducing signal distortion.

High bandwidth: G.655 fiber grade can support higher data transmission rates and adapt to the growing demand for bandwidth in modern networks.

Enhanced power transmission capability: This fiber design allows higher optical power transmission, which can effectively reduce signal attenuation during long-distance transmission.

Low loss characteristics: G.655 fiber grade has low signal loss in long-distance transmission, making it suitable for long-distance fiber links.

Advantages of G.655

High performance: The low dispersion characteristics of G.655 fiber grade make the signal more stable during long-distance transmission, and suitable for applications with high bandwidth requirements.

Economical: Although the initial investment may be high, the total cost of ownership in long-term use is low due to its low loss characteristics and high transmission efficiency.

Flexibility: G.655 fiber grade is suitable for a variety of network topologies and can support a variety of application scenarios, thereby improving the flexibility and adaptability of the network.

Types of G.655 Single-mode Optical Fiber

G.655.D: This fiber is designed to reduce the non-zero dispersion shift (NZ-DSF) effect, making it perform well in long-distance transmission, especially in high data rate applications.

G.655.E: Compared with G.655.D, G.655.E further optimizes the design of the fiber to support higher bandwidth and longer transmission distance, suitable for more complex and high-performance communication networks.
