    7700 MultiFrame Manual 7705DT Fiber Data Transceiver 2.2. OPTICAL CONNECTIONS In order to establish a valid link between a pair of 7705DT modules, one module must be configured as ‘Mode A’, and the other as ‘Mode B’. Selection of the correct mode is achieved by setting jumper J22, at the rear of the board.

    3 cm to avoid fiber-bending loss that will decrease the maximum attainable distance of the fiber cable. The 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 I/O module.
