Page 7: Installation
7700 MultiFrame Manual 7707CVRA Composite Video and Analog Audio Fiber Receiver INSTALLATION The 7707CVRA comes with a companion rear plate that has two BNC connectors, one twelve pin terminal header with removable terminal block and one SC/PC, ST/PC or FC/PC optical connector. -
Page 8: Care And Handling Of Optical Fiber
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. -
