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

  • Page 5: Overview

    The 7708LR 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, such as the 2407LT.

  • Page 6: Installation

    7700 Multi-Frame Manual 7708LR L-Band Fiber Receiver INSTALLATION The 7708LR 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.

    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.
