"
Do not hook up the 7707VT-4 cards that output more than -7dBm of power (see
7707VT-4 specifications for output power of various laser types) and 7707VR-4-H
high sensitivity receiver cards directly with a short fiber optic cable. The 7707VT-4
cards that produce more than -7dBm of power will damage the receiver if
connected directly.
SDI OUTPUT:
Four BNC outputs for four independent reclocked serial digital component video
signals, compatible with the SMPTE 259M, SMPTE 305M and DVB-ASI standards.

CARE AND HANDLING OF OPTICAL FIBER
"
Never touch the end face of an optical fiber. Always keep dust caps on optical fiber
connectors when not connected and always remember to properly clean the optical
end face of a connector before making a connection.
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. 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.
