5G communication refers to the overall system of the fifth generation of mobile communication technology, including access network (AAU/DU/CU), transmission network (fronthaul/midhaul/backhaul) and core network. It is characterized by providing high speed (1Gbps), low latency (1ms) and large connection (1 million devices/square kilometer) capabilities, supporting scenarios such as autonomous driving and the Internet of Things.
5G base stations are the core equipment for achieving wireless signal coverage, consisting of three parts: AAU (active antenna unit), DU (distributed unit) and CU (centralized unit). Among them, AAU is responsible for the transmission and reception of RF signals, DU processes baseband signals with strong real-time performance, and CU completes non-real-time tasks and high-level protocol management. As of 2024, my country has built more than 4.25 million 5G base stations, covering urban and rural areas.
In the construction of 5G base stations, fiber products are the core infrastructure for achieving high-speed, low-latency transmission. With more than ten years of industry manufacturing experience, Yingda keeps up with technological needs and launches a variety of fiber optic cable and assemblies suitable for 5G base stations.
Yingda is committed to the production and sales of 5G optical fiber cables and optical cable components. Our products are widely sold at home and abroad. Welcome to inquire.
The minimum bending radius of G.657.B3 fiber is 5mm, which is 1/4-1/2 of the bending radius of G.652 fiber. G.657B3 cable is soft and smooth, and there is no shape residue after repeated bending. It is suitable for wiring in small spaces and is compatible with G.652D fiber and mainly used in high-density wiring scenarios.
5G base stations can use G.652D fiber, but the wavelength division multiplexing system chooses G657A2 high-bend-resistant fiber; the backbone network long-distance transmission chooses ultra-low loss optical fiber G.654.E, with attenuation ≤0.19dB/km (1550nm), effective area ≥110μm², supports 400G ZR/ZR+ optical modules, and the non-electrical relay distance is increased by 40%. Indoor micro base stations and data centers choose single-mode G.657B3 ultra-bend-resistant fiber and multimode OM5 fiber.
The performance parameters of base station optical fiber products mainly include two categories: optical fiber body performance parameters and optical module parameters. Anti-interference, wiring specifications, and waterproof and dustproof protection are required considering the mechanical strength of the optical cable.
High productivity efficiency, skilled front-line operators and strict production control ensure timely delivery.
High-precision testing equipment and top industry quality control system ensure high quality standards.
Long-term stable supply chain and cost control that changes in line with market trends ensure the best price
