7700 MultiFrame Manual
7705EO-HD SMPTE292M Re-Clocking Electrical to Fiber Converter
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.
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. 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. For further information about care and handling of fiber
optic cable see section 3 of the Fiber Optics System Design section of this manual binder.
