Functions of DXLink Fiber Transmitters and Receivers
The diagram in FIG. 10 below shows the functions of DXLink Fiber Transmitters and Receivers. The example
descriptions contain the device's HDCP key count when used in conjunction with DXLink Fiber Boards in an Enova
DGX Digital Media Switcher.
Important: The DXLink Fiber TX and the DXLink Fiber Input Board must have the same type of fiber optic
transceiver. The DXLink Fiber Output Board and the DXLink Fiber RX must have the same type of fiber optic
transceiver. The multimode and single mode fiber optic transceivers allow for in-the-field replacement and can
even be swapped as long as these constraints are followed.
