RF over Fiber Antenna Extender

Small and mid-size venues often have wireless coverage problems that could be solved easily with an off-air bi-directional amplifier (BDA) or RF booster except the required location for the donor antenna is too far away for coaxial cable to be practical. Optical Zonu’s Antenna Extender solves this problem by providing an easy-to-install fiber optic link between the donor antenna and BDA. The link consists of a compact Antenna Unit that connects to the donor antenna and mechanically identical Equipment Unit that connects to the BDA. The two units are connected by a single strand of optical fiber to provide a robust RF connection for distances up to 3,000 ft.
Th units require no adjustments and can be powered locally or remotely.
The two versions currently available are:
  1. Commercial Cellular: 700MHz, 850 MHz Cellular, 1900 MHz PCS, 2100 MHz AWS, 2300 WCS bands
  2. Public Safety: 700 MHz, 800 MHz
Each unit can be installed indoors or outdoors. For outdoor installations, Optical Zonu also provides the outdoor-rated fiber cable assembly to connect the units. This cable can be fiber-only or hybrid, which includes the DC power connection for the Antenna Unit.
The Equipment Unit connects directly to any BDA with uplink transmit power up to +24 dBm. The Extender provides an essentially lossless downlink RF connection with minimal impact on system sensitivity. RF connectors are rugged N-type. Single mode fiber is standard but there is an option to support multimode fiber.
