TABLE OF CONTENTS / INTRODUCTION
Thank you for choosing the active HDMI 8K fiber optic AOC cable with Ultra-Lock-System™. This cable allows you to transmit HDMI signals up to a distance of 100m without external Power Delivery. The cable is a hybrid cable containing both optical fibers and copper conductors. Our HDMI Active Hybrid Cable is the most competitive HDMI connection solution on the market. It supports a maximum data rate of 12 Gbps per channel, is lightweight, flexible, and has a very small bending radius of only 45 mm. With the embedded advanced optical engine, the HDMI hybrid cable offers full HDMI signal integrity. The patented safety lock is universally compatible with any HDMI socket. Using the 360° locking switch, the connector can be easily toggled between locked and unlocked positions.

- This product is not a toy. Keep it away from children and pets.
- The maximum tensile load of the cable is 150N (15kg). Never pull the cable with a higher load.
- The minimum bending radius of the hybrid cable is approx. 45 mm. Bending the cable to a smaller radius will cause irreversible damage.
- Beware of trip hazards; ensure the cable is securely installed.
- Do not leave packaging material lying around carelessly. It could become a dangerous toy for children.
- Protect the product from extreme temperatures, direct sunlight, strong shocks, high humidity, moisture, flammable gases, vapors, and solvents.
- Do not expose the product to mechanical stress.
- If safe operation is no longer possible, take the product out of use and protect it against unintended use.
Safe operation is no longer guaranteed if the product:
- shows visible damage
- no longer functions properly
- has been stored under unfavorable environmental conditions for an extended period, or
- has been subjected to significant transport stresses.
Handle the product carefully. Impacts, shocks or even drops from a short height can damage the product. Also observe the safety instructions and operating manuals of any other devices to which the product is connected. Consult an expert if you have doubts about the operation, safety, or connection of the product.

OPERATION AND CONNECTION DIAGRAM
Note: The FX-I375 series is designed for use with a +5V passive Power Delivery supplied via Pin 18 on the HDMI connection from the source device. This +5V line, as well as the Power Delivery for the integrated fiber optic module, is transmitted to the Receiver via a standard pure copper connection. Please ensure that the source device can supply more than 500 mA.
Note: This cable can only be used in one direction. The connectors are labeled “SOURCE” and “DISPLAY.” Each plug must be connected to the correct device to avoid signal loss.
- Before using this cable, ensure all devices connected to the AOC-HDMI cable are switched off and not live.
- Connect the “SOURCE” side of the HDMI connector to the Transmitter and the “DISPLAY” side of the other HDMI connector to the Receiver / display. This works without additional Power Delivery.
- We advise against using additional cables or adapters between the connectors as this may degrade signal transmission performance.
- Turn on the HDMI source device and the display.
Connect to the source device.
Connect to the receiving device.
If the system does not function properly, please read the FAQ – Troubleshooting chapter in the next section.
