  • Page 4 7700 MultiFrame Manual 7708LRA and 7708LR-H L-Band Fiber Receiver WARNING Do not connect the 7708LRA without optical attenuation to a transmitter producing in excess of +5dBm optical power. Maximum optical input to the 7708LRA is +5dBm – more power than this may damage the receiver. Do not connect the 7708LR-H without optical attenuation to a transmitter producing in excess of –7dBm optical power.

  • Page 5: Overview

    The 7708LRA/7708LR-H Fiber Optic Receiver is used for receiving L-Band signals transported optically over fiber optic cable by a companion transmitter. It accepts a single optical input and provides dual electrical outputs. It is also capable of decoding and displaying monitoring data sent by compatible Evertz L-Band transmitters, with SmartMON capability.

  • Page 6: Installation

    7700 MultiFrame Manual 7708LRA and 7708LR-H L-Band Fiber Receiver INSTALLATION The 7708LRA/7708LR-H 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.

  • Page 7: 7708Lra/7708Lr-H Connections

    The transmission characteristics of the fiber are dependent on the shape of the optical core and therefore care must be taken to prevent fiber damage due to heavy objects or abrupt fiber bending. 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.
