Wiring for Fiber Communication
Ensure the proper fiber optic cable is used. Typically, singlemode fiber optic
cable has a yellow jacket and multimode fiber optic cable has an orange or aqua
jacket.
Only one fiber optic cable, transmitter-Tx-to-receiver-Rx, is required for video,
audio, serial command transmission, but the HDMI signal output on the receiver
will not be HDCP-compliant and the FOX T USW 103 will not receive RS-232
reports from the controlled device.
