Primary Function: To carry synchronization and timing signals between the primary FSMF System Module and secondary FBBC (Flexi Baseband Expansion) modules within the same base station cabinet.
Purpose: Enables multiple baseband units to operate with a common clock source, which is absolutely essential for:
TDD-LTE (Time Division Duplexing) Networks: Prevents interference by ensuring all modules transmit and receive in perfect unison.
Multi-Module Sites: Allows the base station to scale its capacity by adding FBBC cards while maintaining precise phase synchronization.
Feature Support: Critical for advanced features like Carrier Aggregation (CA) and Coordinated Multipoint (CoMP).
Compatibility: Designed for use with:
Nokia Flexi Multiradio BTS platforms (e.g., FSMF, FBBC units).
Nokia AirScale BTS platforms (backward compatibility is common).
Technical Specifications:
Length: Typically short (e.g., 0.5 to 1 meter), designed for intra-cabinet connections between adjacent modules.
Connectors: Proprietary Nokia connectors designed for a secure, shielded connection to prevent signal degradation.
Shielding: Heavily shielded to protect the highly sensitive timing signals from electromagnetic interference (EMI).
