RF over Fiber CATV TF Mini-node - dual band transceiver. Thor F-MININODE-2RP-HP series transceivers are wideband radio frequency optical modems for bi-directional broadband communications. This platform can have a custom configuration.


  • Excellent optical AGC control when the input optical power range is -9~ + 2dBm, the output level, CTB and CSO basically unchanged
  • Downlink working frequency extended to 1GHz, RF amplifier has high performance and low power consumption GaAs chip, the highest output level up to 112dBµV
  • EQ and ATT both use a professional electric control circuit which allows control for an accurate operation that is convenient
  • Built-in ethernet transponder supports remote network management (optional);
  • Compact structure and easy installation, it's the premeire choice equipment of FTTB CATV networks
  • Built-in highly reliable and low power consumption power supply, or select external power supply(optional)
  • 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
the mini-node is an optical receiver with Return Path
I have a coax demarc from the cable company that carries both internet and TV that I want to convert to fiber optics to enable me to transmit the signal less than a mile to a fiber/RF coax converter to enable me to use the cable companies box to watch TV and have high speed internet.
So in this case you need an RF Optical transmitter; then you need an Optical RF receiver with Return Path, and finally you need a Return Path Receiver; so 3 products total and at least 2 strands of singlemode fiber.
Would this device “L-BAND over Fiber Tx+Rx Basic 1 Ch Kit” be more practical for what I am trying to accomplish?
No this is the wrong equipment for your application
Lband is satellite, which is in a different frequency range then CATV
So because I’m transmitting data it would require me to utilize these three devices, correct?
Data and CATV in the RF band; yes correct.
I would also need to install and use single mode duplex fiber optic cable is that correct?
Yes, minimum 2 strands.
One to send and one to receive.
So for each location I wanted to have cable and high speed internet I would need to run two strands of fiber for each location?
not necessarily, it depends what your fiber layout looks like
or the general design itself
https://thorbroadcast.com/ is sharing a file with you. 1_image.png - (Size:530.37 KB)
in this kind of design you can use an optical splitter to minimize some of the products needed.
Are you able to provide me with a price for these four pieces of equipment, optical transmitter, splitter, optical receiver and the little gray box that goes into the house?
Sure what size optical splitter do you need?
You mention a mile of fiber but do you have an optical budget reading on those strands?
Transmitter 4mW starts at $1995.00 but if you need a larger splitter, then you 'll need a stronger transmitter.
1 to 4 and I saw you had both a rack mounted model and mini version so is there a price difference with these?
4 channel return path receiver
MiniNode with Return Path
how about the optical transmitter?
1x4 rackmount splitter is 400, the compact model is 350
do you offer the fiber optic cable I need in custom cut lengths with connectors?
yes we can do that,
I think the part that maybe throwing you off is that the way we calculate optical power needed is in reverse. The splitter is the largest optical loss device in the drawing, so we count backwards on how many receivers you need, then splitter, then in turn we tell you how much power the transmitter needs to have. 
You can not put two 1x16 splitters in line with that transmitter, the signal won't even make it past the splitter. It's too much loss. 
That's why I'm asking you not to look at the picture, but to tell me exactly what the needs of the project are.
So if you have 21 end points then you need a 1x32 splitter
But since you're dealing with one building and different floors, you should be able to get away with one transmitter, 1x32 splitter, and then XXX receivers; I think 21 as you mentioned is probably the correct number. 
So long as they have singlemode fiber in place, we can help with everything else. 
Just make sure it has SC/APC connectors; otherwise we also sell jumpers if you get any other kind of termination installed.
