Description

RF over Fiber Tx - 8mW Output 45-870 MHz

1310nm - 8mW 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

• 8 mW Optical Power Output from sensor feedback controlled laser system
• Transports entire 45-870 MHz band even with full channel linups
• 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:
1) I'm looking for an RF over Glass solution to go about 4000' and I'm not sure what power output I need. 2) Yeah it’ll be a brand new run of single-mode, no breaks, point to point (minus the end point patch panels). There are no plans for other endpoints at this time. I would assume I just pair up the 4mW Tx with the F-RF-RX-RM and I’m good to go

Answer:
1) Is your application just point to point? Was the fiber installed recently? Is it Singlemode? Do you plan on adding more endpoints in the future? For 4000' our Rackmount 4mW optical Transmitter will be more then sufficient just by assuming there are no couplers and your application is a point to point; if that fiber goes through multiple patch panels and there is a lot of optical loss then we would have to calculate. But for a simple Transmitter and Receiver, the 4mW option should suffice with our receiver because the optical sensitivity in our receivers is also very good. Hopefully, that makes sense, If you'd like to discuss further or need a formal quote please let me know. 2) in this case 4mW Transmitter F-RF-TX-4 and R-RF-RX-RM would be sufficient for this distance, this is a link : https://thorbroadcast.com/product/4-mw-catv-rf-over-fiber-tx-45-870-mhz.html https://thorbroadcast.com/product/catv-rf-fiber-receiver-high-rf-power-rack-8230.html

Question:
1) I'm looking to run convert the RF signal from Spectrum Cable in Davenport FL from their curb access to our house which is about 600 feet away. 2) At this point, I’m not 100% sure. The intention is to split out there internet service through their cable modem and take the ethernet feed-thru an ethernet to fiber converter. Their normal TV channels are all that are needed for your RF to Fiber converter. I’m hoping to NOT even need that. hoping to be a “Cord Cutter” and view all TV channels/ video through the internet/TCP service. I’ll have access shed at the point of service near the road. Planning on running fiber from that to the house which is about 600 feet away. 3) The items below will do the trick. The receiver shows it driving 8 TV's. At this point, I can't imagine having that many in the main residence. In fact, I'm hoping to just have a total "cord-cutting" environment. Internet streaming and OTA (over the air) for local stations. I'm looking at your solution as a, just in case. I have not yet decided on whether the fiber will be single or multi-mode. That will be made when I decide on what the converters will need. Right not the basic need is POTs and Ethernet over fiber. It the actual distance is 500ft including the needed end slack a 1000 ft roll cut in two will provide me with 6 pair of fiber strands.

Answer:
1) I have a couple of of questions for you so I can get you the correct information. Does this feed you have to to include the internet as well? Or is this strictly CATV only? Do you have single mode fiber in place? 2) got it, we can help for both Ethernet over fiber and RF over fiber How many TV's are you planning to serve after the fiber optic RF receiver, We have 2 solutions available for a small amount of TV's and a solution for many TV's This is examples : Ethernet over fiber - point to point https://thorbroadcast.com/product/10-100-1000-mbps-fast-and-gigabit-ethernet-over-1-fiber-media-8230.html RF over fiber TX https://thorbroadcast.com/product/4-mw-catv-rf-over-fiber-tx-45-870-mhz.html RX https://thorbroadcast.com/product/catv-rf-fiber-receiver-high-rf-power-rack-8230.html or https://thorbroadcast.com/product/thor-optical-mini-catv-rf-transmitter-45-1000mhz.html https://thorbroadcast.com/product/thor-fiber-optical-mini-ftth-rf-catv-cable-tv-receiver-8230.html 3) The Pots and Ethernet will work on multimode; however RF will not, RF has to be on single-mode fiber, it won't work otherwise. So just keep that in mind when you put in the fiber.
