  • High Frequency RF Over Fiber

    RF Optic

    RFOptic’s analog RFoF compact modules convert RF signals to optical signals and back. The Tx unit using an optical transmitter converts RF to Optical signal, and the Rx unit converts Optical to RF signal. The two units are connected by the customer’s fiber. RFOptic’s RF over Fiber modules (RFoF) are suitable for telecommunications and radar applications. Satellite, Point-to-Point antennas can be connected from several meters to many kilometers away from the control room. Base stations can be connected through fiber to remote sector antennas. Broadcasters can easily distribute their full RF streams over fiber to remote locations, therefore eliminating the need for complex equipment to be installed in far and hard to reach locations. With our wide-band units, cable operators can centrally locate their broadcasting equipment, and connect the RF through fiber to the remote location, thus reducing significantly the CAPEX and OPEX of their networks.

  • UV Warning Signal

    511 - Solar Light Company Inc.

    The UV Warning Signal model 511 is designed to provide a real-time indication of the sun's UV intensity in an easy to read packaging. Great for outdoor areas; golf courses, country clubs, school yards, outdoor sporting events, amusement parks, ski slopes, beaches, and swimming pools.The concept behind the UV Warning Signal is that it take's the sun's radiation, changes the UV photons of light in the "skin sensitive range" into an electrical signal which activates one of the indicator lights corresponding to the World Health Organization and US EPA UV Index exposure categories. These exposure categories are represented on the UV Warning Signal by five high intensity colored LED indicator lights, and are visible, even in direct sunlight, from up to 50 meters. When in operation the UV Warning Signal illuminates the indicator light that corresponds to the level of UV radiation being received by the sensor.
