With the increase in traffic demand and the development of the Internet of Things and 5G, operators and equipment manufacturers began to consider higher bandwidth to meet the needs of users for high-definition, ultra-high-definition services such as 4k/8K, G.654 fiber. Therefore, it has received more attention.

From a technical point of view: compared to G.652 fiber, G.654.E fiber has no obvious advantages in power-free relay distance, which can extend the transmission distance of no-electric relay, up to 900km or more, and reduce the setting of relay station.

From the perspective of comprehensive cost, fiber optic cable, transmission equipment and office energy consumption, combined with cost considerations, increase the cost of some of the fiber. The use of G.654.E fiber increases the cost of fiber optic cable compared to G.652.D fiber, but the integrated measurement system saves investment and increased investment in fiber optic cable. G.654.E fiber has a slight advantage over G.652.D fiber, and the advantage is more obvious under 400G technology.

From the perspective of operators, low-loss fiber, based on conventional fiber technology, improves the preform purity and wire drawing process and reduces the cost reduction. China Telecom introduced low-loss fiber and ultra-low-loss fiber to promote G.654. Commercial use of optical fiber.

In terms of increasing the effective area, its standardization ITU-T G.654E originates from the large effective area G.654 fiber for submarine cables. Improvements have been made in three aspects: moderate effective area, 110um2 and 130um2; improved macro-bay loss, comparable to G.652 fiber; optimized splice loss, G.654E self-melting loss comparable to G.652.

Through a large amount of practical research and comparison with G.652 fiber, the introduction of G.654 ultra-low loss fiber can increase the transmission distance of the non-electrical relay and reduce the total cost of the optical relay node and the system, thus facilitating future operations. Business and industry jointly carry out the construction of information networks. In addition, in the environment of super 100G development, the new fiber of G.654 series is the trend of the times.
