G.654.E Optical Fiber-The Best Fiber Choice For 200G, 400G And Future TBIT/S Ultra-high-speed Transmission Technology

A series of theoretical research and trials prove that G.654.E optical fiber has both ultra -low loss and large effective area characteristics. Compared with the conventional G.652 optical fiber, it can significantly increase the length of 100G, 200G, 400G, and future higher speed network length. Performance from transmission. Therefore, G.654.E optical fiber is recognized as an effective solution for the next generation of ultra -high -speed long -distance light transmission performance optimization.

G.654.E optical fiber belongs to the new -cut -off -length displacement single -mode fiber, which meets the G.654.E standard. The standard was released by the International Telecommunications Alliance Telecommunications Department (ITU-T) in November 2016. It is the latest version of the ITU-T G.654 "The features of the Deadfords Dead of Modeling Single Model Fiber Cable". Since its release in 1988, the standard has been revised many times, including G.654.A, G.654.B, G.654.C, G.654.D, which are mainly used in submarine cable communication systems.

Like G.654.A, G.654.B, G.654.C, G.654.D optical fiber, G.654.E optical fiber has the characteristics of ultra -low loss and large effective area. In addition, its unique advantage lies in the aspect of working temperature and macro bending. Specifically, the previous four types of fiber are mainly used in the marine environment of constant temperature between -1 ℃ ~ 2 ℃, while G.654.E optical fiber is suitable for land networks, and the environmental temperature can change from -65 ℃ to 85 ℃ Essence In addition, G.654.E optical fiber can resist all kinds of stress and have excellent bending performance to cope with environmental pressure, bending stress, and mechanical impact in the complex environmental environment. According to the above characteristics, G.654.E optical fiber is especially suitable for long -distance high -speed transmission networks on land, not cross -ocean applications. The following table shows the differences in single -mode fiber optical cable characteristics of G.654.a, G.654.B, G.654.c, G.654.D, G.654.E standards.

G.654.E optical fiber increases Optical Signal Noise Ratio value

Optical Signal Noise Ratio (OSNR) is one of the important parameters affecting the quality of light transmission. Because G.654.E optical fiber has two key features: a very small macro bending attenuation and a large effective area, it can effectively maintain the optical power in the fiber core and make it more decentralized, thereby alleviating the Optical Signal Noise Ratio as transmission. The distance is reduced, extend the distance of high speed transmission. The FOM method is used to compare the transmission performance of G.654.E and other long -distance transmission of fiber.

As shown in Figure 1, the FOM on the y axis is an increase in Q-factor incremental Q-factor (for the performance index used to quickly characterize the optical fiber digital transmission system). It can be understood as an increase in the transmission distance Essence 1 decibel advantage corresponds to 25%of the distance increase, 2 decibel advantages correspond to 60%of the distance increase, and 3 decibel advantages correspond to 100%distance increase. It can be seen from the figure that, compared with other long -range transmission fiber, G.654.E optical fiber can provide the best transmission performance, creating a larger space for upgrading to a higher speed.

G.654.E optical fiber extension non -electrical relay transmission distance

Long -distance high -speed light transmission networks are facing huge challenges in extending the distance of non -electrical relay transmission. G.654.E optical fiber increases the size of the core, thereby achieving a large effective area, so that optical fiber can transmit higher optical power. Therefore, compared with the conventional G.652 optical fiber, the optical fiber can extend the optical transmission distance by 70%-100%. It has been proven that G.654.E optical fiber can extend the distanceless relay transmission distance to more than 900 kilometers to reduce the setting of relay stations. The on -site test shows that the combination of G.654.E single -mode fiber and EDFA and DRA can achieve 400G wave score transmission of 2,000 kilometers.

G.654.E optical fiber reduces network deployment costs

Compared with the conventional G.652 optical fiber, G.654.E optical fiber will theoretically increase the cost of optical fiber because of its high price. However, this cost is insignificant compared to the deployment of G.652 fiber in high -speed fiber network systems. Due to the short distance transmission distance of G.652 optical fiber, a more number of optical transmission relay stations need to be set in the network deployment, which increases the total cost, and the G.654.E optical fiber suitable for the long transmission distance can be effective. Reduce the total number and cost of relay stations.

Conclusion

Ultra -low loss, large effective area G.654.E optical fiber can significantly increase transmission performance of 100G, 200G, 400G, and higher speeds. In the next few years, with the continuous large -scale deployment of data center interconnection (DCI), urban network, and other long -distance fiber optic networks, the new G.654.E optical fiber will be expected to obtain a larger application market.
