  • Page 9: Overview

    7706LT Extended L-Band RF Fiber Transmitter OVERVIEW The 7706LT is a fiber optic transmitter for RF signals in the extended L-Band or wider frequency range. It accepts a single RF input on coaxial cable and provides a single output for optical transmission. An RF monitor provides a convenient means of obtaining peak satellite signal strength, or additional signal distribution.

  • Page 11: Installation

    7706LT Extended L-Band RF Fiber Transmitter INSTALLATION The 7706LT 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, FC/APC or ST/UPC 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: 7706Lt Connections

    SC/UPC, SC/APC, FC/UPC, FC/APC or ST/UPC female connector with the optical output from the 7706LT. This connector should be connected to the FIBER IN connector of an appropriate Evertz companion receiver model at the destination end with a suitable fiber optic cable.

  • Page 13: Assembly

    Triangular band: black Symbol: black 2.2.2. Assembly Assembly or repair of the laser sub-module is to be done only at the Evertz facility and performed only by Evertz technical personnel. 2.2.3. Labelling Certification and Identification labels are combined into one label. As there is inadequate space on the product to place the label, it is reproduced here in the manuals.

  • Page 14: Handling And Connecting Fibers

    Evertz recommends that the user 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 are equipped with lockout devices that prevent the user from damaging the fiber connector by installing a module into a slot in the frame that does not have a suitable rear plate installed.
