  • Page 9: Overview

    7700 MultiFrame Manual 7706LR Series OVERVIEW The 7706LR is a fiber optic receiver for receiving extended L-Band and other signals. It accepts a fiber optic input from a companion transmitter and provides an electrical output signal. Control of the card is provided locally at the card edge via DIP Switches.

  • Page 11: Installation

    7700 MultiFrame Manual 7706LR Series INSTALLATION The 7706LR comes with a companion rear plate appropriate for a 1RU, 3RU or standalone enclosure as specified at the time of order. SC/UPC, SC/APC, ST/UPC, FC/UPC or FC/APC optical connectors are available and the type specified at the time of order will be installed. For information on mounting the rear plate and inserting the module into the frame, see the 7700FR manual for detailed instructions.

  • Page 12: 7706Lr Connections

    Evertz recommends that you maintain a minimum bending radius of 5 cm to avoid fiber-bending loss that will decrease the maximum attainable distance of the fiber cable. Evertz fiber optic modules come with cable lockout devices to prevent the user from damaging the fiber by installing a module into a slot in the frame that does not have a suitable rear plate installed.
