Features of the Digital Fiber Optic Repeater Station
- Flexible Topologies: Fully supports chain topology, star topology, and a hybrid combination of both to accommodate complex cellular deployment scenarios.
- One-to-Many Connectivity: The Master Unit (MU) seamlessly supports a star topology, allowing one MU to connect to at least 4 Remote Units (RUs).
- Powerful Daisy-Chaining: A single Remote Unit supports chain connections of up to at least 6 additional remote extensions.
- Long-Distance Transmission: Leverages high-performance optical fiber between the RF Master Unit and RUs, achieving a maximum reliable transmission distance of over 10 km.
- Multi-Operator Sharing: Supports modern multi-operator co-building and multi-carrier sharing infrastructures, optimizing ROI.
