Page 9: Installation
7700/7800 MultiFrame Manual 7807LT-2 Dual Wideband RF Fiber Transmitter INSTALLATION The 7807LT-2 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 10: 7807Lt-2 Connections
SC/UPC, SC/APC, FC/UPC, FC/APC or ST/UPC female connectors with the optical outputs from the 7807LT-2. These connectors should be connected to the FIBER IN connectors of an appropriate Evertz companion receiver model at the destination end with suitable fiber optic cables. The 7807LT-2 may transmit 1310nm, 1550nm or CWDM wavelengths as indicated by the part number on the card ejector. -

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. Labeling 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 12: Handling And Connecting Fibers
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 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. -
