HDMI Modulator and RF over fiber latency demonstration Thor Petit connected to Fiber optic TX and RX

This is a demonstration for showing you how to do HD video Encoding using QAM modulation and transporting it over 10Km of fiber This Specific setup is for applications where HDMI source " ROKU " device is connected to the HDMI RF modulator H-HDMI-RF-PETIT, the CATV RF channel number 2 created by the modulator then output through Coax is then connected to the CATV RF Fiber optic Transmitter, over single-mode fiber optic cable and over to the CATV RF optical receiver, the receiver converts the optical signal to electrical COAX RF signal again. The encoder modulators add a slight delay to the system, the fiber optic Tx and RX ads only 1ms delay.

Question and Answers

Question:
I have two buildings that are connected with a 1500’ 3 pair multimode fiber optic cable. The one location has cable tv and the other does not. I currently have one pair of fibers available and wanted to see if I can send the CATV signal though them

Answer:
Unfortunately, RF Catv can only be transmitted over single-mode fiber. Multimode creates too much dispersion and reflections and the degradation is so severe, and so fast that it is literally impossible to put the cable on multimode. Would it be possible for you to pull a strand of single mode fiber? If possible that product you selected would be an ideal fit for your project.

Question:
I have a question about your RF over fiber products. I realize these all say you must use single-mode fiber with SC APC connectors. I was told by a systems integrator that there is a chance it will work on multimode but it must be OM4 and under 3000 feet. Is this true? If so, what would the expected loss be?

Answer:
The multimode fiber doesn't support CATV RF, the easiest way would be to install the single-mode fiber and use the following devices: Transmitter https://thorbroadcast.com/product/4-mw-catv-rf-over-fiber-tx-45-870-mhz.htmlReceiverhttps://thorbroadcast.com/product/catv-rf-fiber-receiver-high-rf-power-rack-8230.html or if this is impossible, you can use RF to IP and IP to RF gateways.16 QAM to IP https://thorbroadcast.com/product/16-rf-tuners-to-iptv-ts-qam-output.htmlIP to 16 QAM Ethernet over Fiber Converters: https://thorbroadcast.com/product/10-100-1000-mbps-fast-and-gigabit-ethernet-over-1-fiber-media-8230.html

Question:

Now we have pulled RJ 6 cable to all the rooms.

And also we have pulled OFC cable to all the rooms. The cable TC operator will give RF input to their setup box and from the setup, We have to take the audio-video signal to the TV.

I have 6 rooms now. So please tell me what all things I have to buy from you for watching TV with different program in different rooms.

Please give your suggestions.

Answer:

If you have Single-mode fiber in the rooms,

You can use the following units point to multipoint RF over fiber equipment

Question:

I need the recommendation to transport 1 freq over fiber about 500 feet. Freq is 111 MHz.

- 256 QAM

- Kind of what I was thinking just wanted clarification to thank you

- Fabulous Thanks

Answer:

So it's RF; what kind of RF?

- https://thorbroadcast.com/product/thor-optical-mini-catv-rf-transmitter-45-1000mhz.html

The receiver can be either of these

https://thorbroadcast.com/product/thor-fiber-optical-mini-ftth-rf-catv-cable-tv-receiver-8230.html

https://thorbroadcast.com/product/rf-catv-mini-optical-receiver.html

- no problem. there are different types of RF; these particular units are specifically for QAM

- It will transport the entire RF CATV range as well.

Question:

Hi, looking to send cable TV signal over fiber from one building to another

Answer:

Question:

I would like to replace an obsolete set from Force, Incorporated. It is the CATVLite VSB/AM Video Receiver part # 2801R-MCST (receiver) and its compatible transmitter, the 2801T-MCST for wavelength 1310nm. We are transmitting an analog TV signal over multi-mode fiber. Will this be able to replace that? Thank you.

Answer:

CATV and RF in general has to be sent over Single Mode Fiber.

Formerly there were a couple companies who did Catv over multimode because it was analog, and they did very low frequencies, were able to make it work.

All of our units are wide band, covering the entire echelon of RF CATV, 45-870Mhz, which encompasses channels 2-135. Our correlating transmitter and receiver sets will only work on singlemode fiber.

Especially since CATV in general is digital now, I don't even think you can get transmitter and receivers over MM that work in analog,

Please let me know if you have any questions or if you would like a quote on some of our current fiber optic transmitter and receiver sets.

Question:

Hello, I have a question about Optical/Rf power on the F-RF-RX-RM. We recently added the H-4SDI-QAM-IPLL to our system which allowed us to rearrange some things. The H-4SDI-QAM-IPLL and the H-4HD-EMH are sending IP streams to the H-12SDI-QAM-IPLL and then the modulated output is sending out all 20 channels to our CATV distribution. The F-RF-1310-TX-4mW take a feed of the CATV distro and sends it to another building on our campus with a F-RF-RX-RM. We currently get OP 2.6 and -1.6 with the optical pad and we have an RF level of 89. To get 89 we have an ATT-16 on the receiver and a 20db attenuator on the coax going into the transmitter. If we connect the TX and RX together via a fiber jumper we get signal on our test TV. It also works at the fiber patch leaving the building but as soon as we get to the building next door nothing even though the readings are almost the same, the OP is 1.6 on this side. What are the desirable levels? 1x H-12SDI-QAM-IPLL 1x H-4SDI-QAM-IPLL 1x H-4HD-EMH 1x F-RF-1310-TX-4mW 1x F-RF-RX-RM

Answer:

The rules are :

Out fiber-optic RF CATV Transmitter and Receiver need to be connected
with single-mode fiber terminated with SC/APC connectors - this is
very important
RF input power to the F-RF-1310-TX-4mW needs to be +15 - +25dbmv
Optical input power range into Receiver F-RF-RX-RM is +3 - -5dBm

Receiver outputs +45dBmv RF power in this optical input +3 - -5dBm range

You should have the RF output with OP +1.6 dBm, so something is wrong.
Are you using single-mode fiber end to end?
Are you interfacing our equipment with SC/APC fiber connectors?

Question:

This is the current test setup that I will be working with next week.

Can you pass this along to an engineer to see if this setup is ideal?

Answer:

Yes, this is a good setup,

Please just note could facts:

RF Input power should be +15 to +25dbmv

The optical inputs into receives should be 0 to -5dBm

It would be very handy to have a CATV RF meter and optical meter, it will save you a lot of setup time because the RF power and Optical power need to be met in order to work properly and it is very had to determine that without instruments

If you do not have it, we have a very simple RF meter f and an Optical meter

Also in your picture you noted SM-APC for the connectors, I think you mean SC/APC.

Question:

Do you know if you could safely split the output of the transmitter in this kit to connect to 1x4 opticl slitter F-PLC-1X4 up to 4 receivers in total?

Answer:

The Optical output from this unit is +2dbm

The 1x4 splitter F-PLC-1x4 has 7.4db insertion loss

The receivers receiving sensitivity is +3 to -6dbm

You should be fine, it is on the border but it will work

Question:

I was looking for a good solution to pass Analog signal over multi-mode fiber. I work on a ship and the copper run would just be to long to set up a TV from our system. I already have fiber run in the area which is about 800ft of fiber. And the TV would be mounted around 40ft from the receiver at the fiber patch panel. This would be for Analog TV video.

Answer:

Thank you for contacting us.

If you are trying to pass along RF CATV, regardless that it is analog, you can not do it on multimode fiber. Multimode is good for short distances with certain signals, like IP or Video.

However with RF you can only use it with single mode fiber. That could be why you're having a tough time finding a solution, it's not possible.

If you look in our CATV over Fiber products,You will see every single piece of equipment is listed as only being able to work with single mode fiber whether it's HD QAM / ATSC or just SD NTSC Analog.

Generally speaking the only solution here is to pull new fiber.
