Description

RF over Fiber Tx - 4mW Output 45-870 MHz

1310nm - 4mW fiber optic transmitter for Television RF (Radio Frequencies) from 45-870 MHz. Directly converts any incoming RF signal within this band to optical RF. Transports all channels and programs over one fiber. Can be used for point to point, or combined with PLC couplers and fiber optic splitters for point to multipoint applications. Outputs Industry standard RFoG (RF over Glass) signals that can be accepted by most fiber optic RF receivers from other manufacturers. Easy to read front panel LCD provides information and alarm data, and simplifies configuration. This system features a highly linear DFB laser with automatic adjustment circuitry with Automatic Gain Control. For added reliability, a second internal Power Supply Unit is available as an option.

Transmitter can be used with any or Thor Fiber optical RF receivers

F-RF-RX-RM CATV RF Rack- Mountable Receiver High Power	F-RF-RX-MN CATV RF Mini optical receiver	F-Mininode CATV Mininode -RF Receiver and return path RF transmitter

Features

• 4 mW Optical Power Output from sensor feedback controlled laser system
• Transports entire 45-870 MHz band even with full channel lineups
• Create high security "Fiber Breaks" to eliminate coax signal return path
• Automatic Gain Control (AGC) manages RF level with no adjustment needed
• Compatible with all Thor RFoG CATV series optical receiver systems

IMPORTANT NOTE*** (it is very important to interface our unit with SC/APC - Angle Polished Connector to avoid any light reflections.

If your fiber is terminated with the SC, ST, FC /PC flat connector, you need to use an optical jumper from PC type to SC/APC for proper conversion.

Question and Answers

Question:
I'm inquiring about having a proper setup for converting tv channels from coax cable to fiber and then fiber back to coax cable. I have tv channels designated with their own channel number and I combined the channels with a combiner. Then a single coax cable comes out of the combiner and is distributed to all the hotel rooms with coax splitters. A group of hotel rooms are located in a different building. We have new fiber running between the buildings, and our coax cable between the buildings is deteriorating. We're hoping to be able to transfer tv channel signals from coax to fiber and then fiber back to coax. Is the "2 mW CATV RF Over Fiber Tx 45-870 MHz" the proper device to convert tv channels from coax to fiber? Is the "RF CATV Mini Optical Receiver" the proper device to convert the tv channels from fiber back to coax?

Answer:
Yes, for 12TV's and 200 feet of single mode fiber, 4mW OTx and the mini receiver are sufficient. It has to be single mode fiber with SC/APC termination. We've been helping customers with these kind of applications for a long time, it's our niche. This would be an ideal solution for what you're trying to accomplish. As we noted previously we have everything in stock, if you'd like to move forward with a purchase please let us know. We can accept a credit card or PO.

Question:
I am a technician trying to figure out (without passive attenuators) how to attenuate the optical level from one of your CATV AM Transmitters.

Answer:
The only reliable way is to use optical SC/APC attenuators, there are some "temporary test methods " 1 connect an optical fiber to the meter and Bend the fiber slightly gently; but not too much of an acute angle to avoid damaging it. 2 Remove the fiber jumper slightly from the adaptor to create an air gap, you can monitor the loss using the Optical Meter

Question:

What parts would you recommend to distribute CATV between buildings?

Signal: 195 MHz - 477 MHz (center frequency)
Modulation: 256 clear QAM
Distribution from one building to five buildings
Fiber path: <5km
Single mode SC UPC connectors at patch panels.

Answer:

Thank you for reaching out to Thor Fiber.

To send CATV RF from one location to 5 remote locations, please use the following equipment:

F-RF-1310-TX-16MW: 16 MW CATV RF transmitter - $2995 - https://thorbroadcast.com/product/16-mw-catv-rf-over-fiber-tx-45-870-mhz.html
F-PLC-1x8: 1x8 optical splitter - $495 (no 5-port available) https://thorbroadcast.com/product/1-x-2-to-1-x-128-fiber-optic-couplers.html/226
F-RF-RX-RM: Optical to RF high-power receiver - $1595 each - https://thorbroadcast.com/product/catv-rf-fiber-receiver-high-rf-power-rack-8230.html
- High dual power output: 45 dBmV each, eliminates the need for RF amplifiers.

Please note that this equipment requires single-mode fiber only (not multimode) and must be interfaced with an SC/APC (angle polished connector).

One more thing: if you have SC/PC connectors on your patch panel, you will need to use conversion cables (jumpers) — SC/APC (for our devices, green) to SC/PC (flat, blue) to connect to your patch panels.

Question:

I need a box to transmit RF across the fiber. We need to send ATSC TV bands from our antennas on the tower inside the building. We will have both single-mode and multi-mode fibers with LC connectors at the patch panel. We need one transmitter and one receiver only for the RF, and patch cables. Can you add it to the quote? Also for the ASI box, we need patch cables for ST on the box to LC at the patch panel.

Answer:

We do have portable RF TX/RX or rack-mountable, which one would you prefer:

Portable Mini TX/RX:

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

19" rack-mountable

https://thorbroadcast.com/product/catv-rf-fiber-receiver-high-rf-power-rack-8230.html

The devices require single-mode fiber, the interface is SC/PC, so you would need 2 optical jumpers LC/PC to SC/APC

Question:

Have a project that the local cable company brought in coax and we need to transition to fiber into our treatment plant. looking for technical advise on making sure your product is the correct solution.

Answer:

Okay we certainly have the gear available that you need, but to narrow it down I just have a couple basic questions.

What is the distance of your single mode fiber? Do you already have SC/APC terminations on the singlemode?

Do you need bidirectional or is this application just going unidirectionally?

If this is uni- directional transmission ( Cable TV video only)

you can use those TX/RX units , 1 single mode fiber is required SC/APC fiber connects

F-RF-RX-MN-2

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

If this is Bi-directional ( Cable TV + Internet)

You can use this unit, 2 single mode fibers are required, SC/APC fiber connects
