1. Interface Specifications
   • Antenna Ports: 4×4.3 - 10 (F) ports with a 50Ω impedance match.
   • Baseband Connection: Connects to the baseband unit (BBU) via fiber optic cables, supporting transmission rates of 2.5/4.9/9.8/10.1 Gbps through replaceable SFP modules.It can be deployed up to 40 km away from the BBU and supports cascade or star connection topologies for multiple units.
   • Auxiliary Interfaces: Supports AISG TMA and RET protocols for antenna system control via RS - 485. It is also equipped with 1 maintenance button, 2 external alarm ports (using DIN 14), and optional external monitoring ports for output power measurement of specific band
