The EMTS Telecom Services Ltd. F/O DAS solution provides an affordable solution for multi-operator 5G indoor signal coverage problems for multi-operator deployment. The Master Unit (MU) is based on POI, Attenuator box, and Fiber Conversion Box Unit (FCB). One Master Unit (MU) is connected to 2 Extension Units (EU). Each EU is connected to 8 Fiber Remote Units (FRU) via fiber optic cables. The gNB RF signals of all 4 operators are fed to the 5G POI. The POI combines all 4 operators into 4 MIMO streams. The combined RF signal is attenuated using an attenuator box and fed into the FCB. The MU converts the RF signal to an optical signal, 1 signal per MIMO stream. The optical signal is connected to the Extension Unit (EU) through F/O cables. One MU supports 2 EU. The EU splits the optical signal from the MU into 8 optical signals for the fiber Remote Unit (RU) via fiber optic cable. The fiber RU will reconvert the optical signal into an RF signal and provide the signal to the areas where network coverage is inadequate. The mobile signal is also amplified and retransmitted to the BTS via the opposite direction. The EMTS 5G Fiber Optic Repeater system is designed to support MIMO 4X4 topology. The EMTS Telecom Services 5G DAS solutions boost network performance to stay ahead of the fast-moving 5G multi-operator deployments & get a fast ROI simultaneously.

Key Features
- 5G RF Extension 4 x4 MIMO system supports TDD technology
- Allows fast 5G NR network deployment
- Designed to comply with ETSI 3GPP TS 38.104
- Supports NSA (Non-Standalone) and SA (Standalone) 5G network
- One Master Unit can support 2 Extension Units (EU), and One EU can support Up to 8 Fiber Remote Units (FRU) to maximize the utilization of fiber optical cable (a star topology is formed between EU and FRUs)
- Master Unit is based on the standard 5G EMTS advanced POI connected to an Attenuator box and Fiber Conversion Box (FCB)
- The POI combines the 4 mobile carriers into 2 X 4 outputs
- The 4 outputs from the POI will be equalized using the attenuator box
- Easy installation and easy maintenance can be managed through EMTS OMT/NMS
