The 5.0/7.0 mm FTTA (Fiber to the Antenna) base station remote optical cable is designed for high-speed optical signal transmission in 4G and 5G mobile communication networks. It connects baseband units (BBUs) with remote radio units (RRUs) or remote radio heads (RRHs), providing reliable connectivity for outdoor base stations, distributed antenna systems (DAS), and small-cell installations.
Featuring a dual-fiber single-mode design, precision tight-buffered fibers, high-strength aramid yarn reinforcement, and a flame-retardant low-smoke zero-halogen (LSZH) sheath, this cable combines flexibility, mechanical protection, and environmental durability. Two versions are available: a lightweight 5.0 mm cable for flexible routing and a reinforced 7.0 mm cable for demanding outdoor installations.
Key Features
- Designed for 4G and 5G Networks: Supports optical connections between BBUs and RRUs/RRHs for reliable base station signal transmission.
- Single-Mode Dual-Fiber Design: Provides two optical fibers for communication links between base station equipment.
- Flexible Fiber Options: Supports G.652D single-mode fiber, with bend-insensitive G.657A1 or G.657A2 options available according to project requirements.
- Tight-Buffered Fiber Construction: Helps improve handling, bending performance, and resistance to mechanical stress during installation.
- High-Strength Aramid Reinforcement: Provides tensile strength and helps protect the cable during routing and installation.
- Flame-Retardant LSZH Sheath: Reduces smoke and eliminates halogen content in the sheath material, making it suitable for communication installations with low-smoke, halogen-free requirements.
- Outdoor Environmental Protection: Designed for a wide operating temperature range, with reinforced sheath options for improved abrasion and UV resistance.
- Waterproof Connector Compatibility: Supports compatible base station connector interfaces, including ODVA, ODC, NSN, FULLAXS, and waterproof LC options, depending on configuration.
Product Overview
FTTA base station remote optical cable provides a reliable optical connection between base station processing equipment and remote radio units installed near antennas. By transmitting signals over optical fiber, it supports the high bandwidth and low signal-loss requirements of modern mobile communication networks.
The cable uses a precision tight-buffered fiber structure to simplify handling and improve protection during installation. High-modulus aramid yarn surrounds the cable core, providing tensile reinforcement while maintaining a compact and lightweight construction. The black LSZH outer sheath offers flame-retardant properties and is suitable for communication equipment installations where smoke and halogen emissions need to be controlled.
Two cable diameters are available to accommodate different installation environments. The 5.0 mm slim version offers excellent flexibility and a lower cable weight, making it suitable for confined spaces, cable ducts, and routes requiring easier handling. The 7.0 mm reinforced version features a thicker sheath and additional aramid reinforcement to provide improved abrasion resistance, outdoor durability, and higher allowable tensile loads.
The cable supports operating temperatures from -40°C to +75°C and storage temperatures from -50°C to +85°C. When supplied with compatible waterproof connectors, the assembly can achieve IP67 or IP68 protection, subject to the selected connector and configuration.
Connector types, fiber specifications, cable diameter, and reinforcement levels can be selected according to the base station equipment and installation conditions. This flexibility makes the product suitable for a wide range of FTTA deployments, including 4G/5G base stations, distributed antenna systems, and outdoor wireless communication infrastructure.
