Avago 471692A.101 FOSB Fiber Optic Cable Assembly

The Avago 471692A.101 (FOSB) is a high-performance Fiber Optic Cable assembly designed specifically for high-speed data transmission between telecommunications infrastructure units. This assembly is primarily utilized in Base Transceiver Station (BTS) environments, such as the Nokia Flexi and AirScale platforms, to provide reliable optical connectivity between System Modules and Radio Heads. The cable features premium-grade optical fibers optimized for low attenuation and minimal signal dispersion over short to medium distances, ensuring consistent performance in high-bandwidth 4G/LTE and 5G applications.The 471692A.101 is engineered for ruggedized telecommunications use, featuring a durable outer jacket that provides excellent resistance to ultraviolet (UV) radiation, moisture, and extreme temperature fluctuations ranging from -40°C to +85°C. The connectors are precision-aligned to ensure low insertion loss and high return loss, which are critical for maintaining link budgets in sensitive optical networks. This Fiber Optic Small Form-factor (FOSB) solution often incorporates specialized strain-relief boots to protect the fiber core from mechanical stress, bending radius violations, and vibration-induced micro-fractures during installation or maintenance in congested cabinets.
The assembly is fully compliant with international telecommunications standards for flame retardancy and smoke emission (LSZH - Low Smoke Zero Halogen), making it suitable for both indoor and outdoor-to-indoor transition deployments. Each cable assembly undergoes rigorous factory testing for optical continuity and end-face cleanliness to meet carrier-grade quality requirements. The 471692A.101 serves as a reliable link for CPRI (Common Public Radio Interface) or OBSAI protocols, providing the necessary throughput for real-time mobile data processing in modern cellular network topologies.
