Core Advantages and Key Performance Features
SkywardTelecom CPRI cables are purpose-built for outdoor base stations and FTTA (Fiber-to-the-Antenna) deployments. Combining industrial-grade durability with professional-grade transmission performance, they are suitable for a wide range of mainstream engineering applications:
1. Industrial-Grade Outdoor Environmental Adaptability
Unlike standard indoor fiber optic jumpers, our CPRI cables feature a fully reinforced, ruggedized structure with an IP67 protection rating. With superior resistance to salt spray, moisture, humidity, dust, and water, they operate reliably in extreme conditions—including high and low temperatures, strong winds, heavy rain, and coastal salt-laden air. The reinforced metal housing effectively withstands external crushing and tensile stress, making them ideal for top-of-tower antenna connections and remote outdoor fiber feeder deployments.
2. Standard Duplex LC Connectors for Broad Compatibility
All CPRI cable products are equipped with standard duplex LC connectors, ensuring seamless compatibility with mainstream LC adapters, optical modules, and BBU/RRU equipment. This standardized interface design greatly simplifies on-site cabling, installation, and maintenance, minimizes integration errors, and enhances overall construction efficiency for base station projects.
3. Dual Options: Single-mode and Multimode
To meet the diverse requirements of various network architectures and transmission distances, SkywardTelecom offers both single-mode and multimode CPRI cable options. Single-mode models are designed for long-distance base station signal transmission, while multimode models are suited for short-distance, high-speed link connections, allowing for flexible alignment with various communication network construction standards.
4. Ultra-low Loss and Stable Signal Transmission
Our CPRI cables feature ultra-low insertion and return loss, effectively preventing signal distortion and transmission interruptions during long-term operation while ensuring continuous, stable, and high-speed optical signal transmission.
5. Lightweight Structure and Long Service Life
The lightweight cable design reduces the load for tower-top installation while offering excellent flexibility and bend resistance. These cables boast a mating durability of up to 500 cycles and exceptional resistance to aging and weather. They maintain stable performance during long-term outdoor use, significantly reducing the frequency of equipment replacement and project O&M costs.
Wide Range of Application Scenarios
CPRI cables are utilized across virtually all mainstream cellular network application scenarios:
- FTTA (Fiber-to-the-Antenna) Systems: Specifically designed to connect tower-top RRUs (Remote Radio Units) with antennas, enabling efficient optical signal transmission between base station equipment and antenna terminals, and supporting the large-scale deployment of outdoor distributed base stations.
- Multi-Generation Base Station Networking: Compatible with the deployment of 2G, 3G, 4G, and 5G base stations across all standards, ensuring stable data transmission links between the BBU (Baseband Unit) and the RRU.
- Outdoor Projects in Harsh Environments: Suitable for outdoor tower installations, remote base station construction, coastal telecommunications projects, and other challenging environments, effectively resolving link instability caused by complex environmental factors.
