Troubleshooting FAQ
1. What can I do if the “Link” LED indicator is not solid on, blinking or off?
- Make sure you have used a multi-mode optical fiber cable to match the included multi-mode SFP module. If you are using a single-mode optical fiber cable, you need to purchase an extra single-mode SFP module.
- Make sure you have used a duplex OM3 fiber cable and cross-connected it (TX-RX, RX-TX). The cable length must be within 300m/1000ft.
2. What can I do if there is no video output?
- Check if the “Link” LED indicator is in normal status (solid on). If not, please check your SFP module and optical fiber cable connection.
- Check if the “HDCP” LED indicator is in normal status (solid on). If not, please check your HDMI cable connection.
- Check if you have chosen the right HDMI input channel on your display device.
- Try connecting the PC to the display device directly via an HDMI cable. Then check if there is any video output.
3. What can I do if IR connection is not working?
- Make sure you have toggled the DIP switch (on both the transmitter and the receiver) to the “IR” position.
- Check if your IR connection method is correct. The IR receiver cable needs to be connected to the “IR In” port at one end, and the IR emitter cable needs to be connected to the “IR Out” port at the other end. Please note that the 3.5mm cable connectors need to be fully inserted into the IR ports.
- Check if you use the remote controller correctly and if you place the IR emitter head correctly. When you use the remote controller, it needs to be directly facing the IR receiver head. Besides, the IR emitter head should be placed closely to the IR receiving window of the controlled device.
- Try controlling the source device directly via your remote controller, without using the HDMI extender. Then check if the IR connection works.
4. What can I do if RS232 connection is not working?
- Make sure you have toggled the DIP switch (on both the transmitter and the receiver) to the “RS232” position.
- Check if the connection method of the RS232 cable between the HDMI extender and the control/controlled device is correct. It should be “TX-RX, RX-TX, GND-GND”.
- Perform an RS232 loopback test to see if the HDMI extender’s RS232 pass-through function can work normally.
- Try connecting the control device and the controlled device directly without using the HDMI extender. Then check if the RS232 connection works.

I love this device!
4K@60FPS, 4:4:4, DTS over the optic fiber.
I love this device. If you want to move your equipment to a closet or storage room, allowing you to tidy up some space in your living room – this is just great. It is small enough you could easily attach it to a backplate of your TV, leaving just an optic fiber and a charging cable as the only indicaton there’s anything really going on.
lag/latency is completely negligible and you won’t experience it. If you want to play games – it will work just fine.
finally, it looks like the device uses a single SFP+ port on either side, and comes with a preinstalled LC connector. While i haven’t really tried this, it wouldn’t surprise me if it worked over different media, too.

Can’t say enough good things about the customer service I experienced here. First, I bought the wrong model. Returned was totally painless, fast and I had the right one in hand in no time. Once I got the correct model, it worked beautifully. Fast forward maybe two years and I ran into an issue. Reached out to the company and couldn’t believe how committed they were to helping me resolve my problem. Offered me a number of options, including return. I opted to do an exchange and pay a minor price difference for a newer model with ARC. In all my years of online buying, I can’t recall a situation where I was able to so easily resolve a tech issue and come away better off then when I started. I can’t speak to the unit in comparison to others as I’ve only owned one, but the price was excellent, and I was happy with the performance. And most of all now, I feel really good about who I bought it from. Thank you!

I hooked up my gaming computer behind the couch and my rec room. With these boxes, around cat seven between them and have perfect 4K quality on my Sony 80 inch Bravia. I am so impressed�I think I’m going to buy their one by four splitters to hook up my cable box to four additional TVs eliminating the need to pay monthly for a cable box in those rooms.

I needed to extend 4K video beyond what the available CAT6A/7 video extenders provide – I have tried a lot of them, but cable run distance is always an issue for me. In my setup I use a 4K home theater receiver, multiple HDMI sources, and a 4K projector throwing over 20 feet. I used a 35-meter OM4 LC to LC multimode fiber cable rated for 10Gbps, and I also used all 4K HDMI 2.0 cables for each connection.
When I first got this going, there was some intermittent flickering and then loss of signal that would return after about 5 minutes and then go out again. I worked with Ryan at the support team, and he asked me to test multiple components of mine (i.e., TV for projector, laptop as source to extender directly, etc.) just to make sure I had everything correct, and we determined to swap the AV Access extender units. Once I sent the units back, I got the new units almost immediately. I plugged in the new units and everything worked without any issues at all.
I am very pleased with the performance of the unit, the quality of the power adapters, connections, LC SFPs, and overall look of the extenders. Also, working with support was not an issue at all, in fact it was refreshing to get the level of respect that exceeded my expectations. They did offer full reimbursement if that was what I wanted. Since I haven’t found any other solution worthy to compare to this, I was thankful to get the immediate replacement without any hassle.
