  • Publication number: 20120315035
    Abstract: A communication system for providing downlink and uplink communication between Service Providers, and users located in RF remotely located isolated areas, includes the sequential series connection of Service Provider signal sectors to Radio Interface Modules (RIM's), Service Combiner Units (SCU's), Fiber Transceiver Units (FTU's), Optical Multiplexer Units (OMU's), and Remote Fiber Nodes (RFN's), with only the RFN's being located in the RF isolated areas.
    Type: Application

  • Patent number: 8326156
    Abstract: A communication system for providing downlink and uplink communication between Service Providers, and users located in RF remotely located isolated areas, includes the sequential series connection of Service Provider signal sectors to Radio Interface Modules (RIM's), Service Combiner Units (SCU's), Fiber Transceiver Units (FTU's), Optical Multiplexer Units (OMU's), and Remote Fiber Nodes (RFN's), with only the RFN's being located in the RF isolated areas. The RIM's provide level control of RF signals bidirectional flowing between the Service Providers and SCU's. The SCU's both multiplex and split received downlink RF signals for inputting to the FTU's, and also combine and split RF uplink signals received from the FTU's for feed to the RIM's. The FTU's convert downlink RF signals into optical signals, and split the optical signals for connection to the OMU's. The FTU's also convert uplink optical signals received from the OMU's into uplink RF signals for connection to the SCU's.
