Description

F-CELLULAR Fiber Optic Tranciever for cellular frequencies : GSM, PCS, and CDMA Base Station Links

The F-CELLULAR systems are linear fiber optic transceivers for cellular over fiber applications specifically designed for high performance optical links between cellular base stations (BTSs), links between BTSs and microcells, or general radio over fiber (RF over Fiber) applications. We offer equipment for CDMA over fiber, GSM over fiber, WiMAX over fiber as well as more modern standards such as 3GPP over fiber. This is useful for extending the range of a wireless celluar network. When connected to a wireless antenna an F-CELLULAR unit amplifes the incoming RF signal, converts it to an optical signal, transports it over a fiber optic cable to a second F-CELLULAR unit, and then reconverts the signal back to an RF carrier for rebroadcast over a second antenna. This system can be used to extend coverage of a wireless cellular network to an area up to 120 km from the source. Our F-CELLULAR units are a low noise, radio frequency fiber optic transceiver for cellular over fiber applications. Our units are designed for applications such as CDMA over fiber, GSM over fiber, and other cellular over fiber applications. RS-232 control signals can also be carried over the same optical fiber. Our optics offer high linearity and superior performance over a wide range of operating temperatures. Operation over a single fiber is enabled through the incorporation of a WDM system at 1550 and 1310 nanometers.
