Fiber optic connectors and LEDs —
CAUTION: These units output continuous invisible light, which may be harmful to
the eyes; use with caution. For additional safety, plug the attached dust
caps into the optical transceivers when the fiber cable is unplugged.
NOTES: • Ensure that you use the proper fiber cable for your transmitter/receiver
pair. Typically, singlemode fiber has a yellow jacket and multimode cable
has an orange or aqua jacket.
• Only one fiber optic cable, transmitter-Tx-to-receiver-Rx, is required for
video, audio, and serial command transmission. But, if you connect only
one fiber optic cable, or if your receiver is configured to daisy-chain the
optical signal:
The HDMI signal output by the receiver is not HDCP-compliant.
•
You will not receive RS-232 reports from the controlled device.
•
To receive responses from the controlled device and for HDCP
compliance, you need to install both fiber optic cables and leave link
