Key Benefits
Dual Hot-Standby Redundancy
Critical components, including the power supply and power amplifier, adopt a dual hot-standby architecture.If one module experiences an abnormal condition, the redundant module helps maintain system operation, reducing the impact of a single component failure and improving overall system availability.
One-to-One Optical Link Architecture
The optical modules between the near-end and remote units adopt a one-to-one architecture.Compared with conventional one-to-multiple-remote-unit architectures, this design prevents a single near-end optical module failure from affecting multiple remote units simultaneously, helping reduce failure impact and improve overall system reliability.
Dual Base Station Access
In systems requiring redundant coverage from two base stations, a single remote unit can simultaneously receive signals from two independent communication base stations, enhancing signal-source redundancy and communication availability.
Coverage for Signal Blind Spots
The system extends wireless coverage into areas where radio signals are weakened or blocked by complex building structures, helping eliminate coverage blind spots and maintain reliable communications in challenging environments.
