L-BAND over Fiber Tx+Rx Basic 1 Ch Kit

Answer:
Yes this unit F-LBAND-TX/RX supports 50-2800Mhz RF input. The ATSC spectrum RF is between 50-800 MHZ, the satellite L'Band is between 850-2100Mhz  Using this TX and RX you can send both signals. You can simply combine the signal from the dish and from the residential antenna using smile 1x2 splitter/combiner   If there is short distance than Coax is a better and less expensive choice  It is great for sending signals from the Dish or ATSC or both for long-distance, let's say that some residence doesn't want to have a big dish next to the house, or skyscraper needs to send the signal to the master headend located in the basement. Standard TX/RX supports up to 20Km of fiber.   Yes we can send you 200-300 feet of fiber with the TX/RX .   Please note this unit is able to extend1 LNB,  some satellite services like Direct TV uses multiple LNB's , in this case we have different units 4 or 6 LNB over 1 fiber extender. those units actually convert every LNB input on separate light wavelengths ( colors of light ) and internally passively combine them , receiver separate the light using filters and convert it back to the original Lband RF (it gets complex)    those are the links : https://thorbroadcast.com/product/4-ch-l-band-over-single-fiber-extender-45-3000mhz-cwdm.html https://thorbroadcast.com/product/6-ch-l-band-over-single-fiber-extender-54-3000mhz-cwdm.html    

Answer:

s the application just point to point? Is the CATV QAM or ATSC?

Does the customer have Single mode fiber in place with SC/APC connectors? What is the approximate distance of the fiber? Or do you know the optical budget/loss? We have an abundance of products for this kind of application. https://thorbroadcast.com/products/cable-tv-catv-rf-45-900mhz Transmitter and receivers are readily available and in stock, just need to a know a little bit more information so we can point you in the right direction.

Answer:
  Sirius satellites broadcast within the s-band frequencies from 2.3200–2.3325 Ghz , while XM radio uses adjacent frequencies 2.3325–2.3450 GHz. So a few things here, realistically it should work then.  A Couple of options or things to consider is, does the XM antenna require power/voltage to the antenna? Does the antenna require bidirectional communication?   The other options we have are  Trying the new set  https://thorbroadcast.com/product/l-band-over-fiber-tx-rx-basic-1-ch-kit.html Again, updated specs and it could possibly work, even though its the same frequency range.    Another option is to go up a level and try these: https://thorbroadcast.com/product/4ghz-fiber-optic-mini-transmiter-receiver.html If you look in the description it's made for S BAND  It is used in many RF over fiber applications like communications, defense systems, satellite L-band, S-band, GPS, WiMAX, cellular 3G, 4G and LTE signals.       These articles goes over more stuff https://electronics.howstuffworks.com/satellite-radio.htm#:~:text=XM%20Radio's%20ground%20station%20transmits,170%20channels%20of%20digital%20audio. https://www.lifewire.com/what-is-a-satellite-radio-antenna-534489

Answer:
We have a few different options to choose from.  We have individual sets in compact format  https://thorbroadcast.com/product/l-band-over-fiber-tx-rx-basic-1-ch-kit.html   Depending on the voltage of those 2 Lbands you could possibly use this set: https://thorbroadcast.com/product/2-satellite-lband-1-catv-qam-atsc-rf-8230.html   For the 9 Antenna's we have 6 Channel Mux units available  https://thorbroadcast.com/product/6-ch-l-band-over-single-fiber-extender-54-3000mhz-cwdm.html   Please let me know if you have any questions or would like a formal quote.  If you would like more information or would like to discuss you can reach us at 1800-521-8467 ext 2   Please note all of our LBAND equipment requires singlemode fiber and is terminated with SC/APC connectors. 

Answer:

 

We have two kinds of systems of Lband, compact and rackmount. The rackmount systems all use CWDM and have either 4 or 6 LNB inputs.  The compact units are single units with one LNB.  All of these units can power the LNB from the transmitter. 

Answer:
Yes, absolutely, we know for a fact that many companies are using them in conjunction with Dish services in MDUs.

Answer:
That's correct, we do not offer it, because it's impossible to put RF on multimode fiber.  If you would like to use HDMI over Fiber for a very short distance on multimode, we do have a solution for that.  https://thorbroadcast.com/product/hdmi-fiber-extender-with-ir.html Cost for the transmitter and receiver is $495.00 and does come with accessories like power supplies and Red Eye.  Let me know if that will work for you.

Answer:

I'd be happy to clarify how we can extend Direct TV signals using our Lband  Fiber Optic extenders products. Direct TV usually has four or more LNBs, which are connected directly via four or more coax cables into the SWM. The SWM has RF output/input and communicates with the STBs in both directions. Since fiber optic is strictly unidirectional, we can only extend the 4/6 LNBs' signal into the SWMs, not from SWIM's to set-top boxes. ( so we can not use F-LBAND-TX/RX from your splitter MSPLIT8R1-03 ) The easiest way to help you with your application would be to use the F-LB41-TX 4 L-band Transmitter (4 LNB fiber optic extender with a 1x4 Optical Splitter and three F-LB41-RX receivers. These receivers would be connected to three SWMs where you can run your 1x splitters and set-top boxes. Please check the link below for a drawing to visualize your application:

https://thorbroadcast.com/product/4-ch-l-band-satellite-over-single-fiber-extender-transmitter-and-8230.html  

If your Direct TV has more than four LNBs, please consider the LB61. https://thorbroadcast.com/products/l-band-satellite-rf-45-3000mhz

Our units requires single mode fiber and SC/APC connectors, if you have LC/PC than you will need to use LC/PC to SC/PC optical jumpers on each end of the fiber Please let me know if this is clear.

Answer:
Thank you for your inquiry regarding our RF over fiber solutions. We specialize in "Fiber Brake" RF to Fiber equipment and have extensive experience working with DoD, military, and government agencies.   We have several options available for your application.  The main question is what satellite service you are using and how many LNBs you need to convert to fiber. For example, DirecTV typically has 4 to 6 LNB dishes.   Please check the link below for more information on our L-band satellite RF to fiber extenders:   https://thorbroadcast.com/products/l-band-satellite-rf-45-3000mhz   Example: F-LB61-TX/RX https://thorbroadcast.com/product/6-ch-l-band-satellite-over-single-fiber-extender-transmitter-and-8230.html        

Answer:

Thank you for reaching out. Yes, this is correct—the Fps over fiber devices work as a transmitter and receiver pair. The F-4GPS-TX-WE is an optical transmitter only, converting the RF GPS electrical signal into an optical output. The F-LBAND-TX/RX is a receiver only, which converts the optical signal back to the original electrical GPS RF signal. Therefore, the device functions as a GPS RF extender over fiber and, importantly, acts as a Physical Isolator. We refer to this as a "fiber break" because it creates an inability to send any signals back from the RX to the TX. The RX is not equipped with any laser; it is just an optical detector.

If you only need one GPS, here is the link to the F-1GPS-TX/RX, which will get the job done. Please note that we also have a very similar solution for Satellite Antenna L-band over fiber (F-LBAND-TX/RX) and for Cable TV RF with a fiber break. These devices are essentially rated for different RF frequency ranges.

They are essentially rated for different RF frequency ranges. https://thorbroadcast.com/product/rf-fiber-break-optical-rf-coax-isolation-solution.html   In your application, which signal would you like to isolate: GPS, L-band, or CATV RF cable?

 

Answer:
LTE cellular over fiber solution :   However those are unidirectional transmitter and receiver sets, for cellular you would need two sets and an RF circulator.  Hopefully that makes sense; but we have had clients use that as a solution for Cellular over Fiber and works great, so long as your RF spectrum stays at or below their threshold.

Answer:
For the single channel Lband compact kits, the RF input level: 55 - 78 dBµV Output RF Response Levels Optical Input = 0 dB        RF Output = 88 dBuV Optical Input = -3 dB       RF Output = 82 dBuV Optical Input = -6 dB       RF Output = 74 dBuV Optical Input = -9 dB       RF Output = 68 dBuV Optical Input = -12 dB     RF Output = 63 dBuV   Optical input power range -13 - 1 dBm (sensitivity -13 dBm) Can provide LNB power at 13/18 VDC over coax Can provide 22 kHz control tone for LNB polarity shifting   Those compact sets are easily compatible with ranges up to 10km, generally much further.  300m is a very short distance, they will be plug and play units.  Please make sure you are using Singlemode fiber and have SC/APC terminations. We do offer jumpers in various sizes and terminations if needed. 

Answer:

1) - To confirm the setup for your DirecTV system and which Lband RFoF which would fit your system; do you know how many LNB's your Dish has? And does it have a SWM built into the dish?

If you aren't sure, please send us the model numbers of which Dish you have; they vary between 1 to 5 LNB's generally.    For fiber topologies with dishes, the fiber transmitter and receiver go in between the dish and the SWM; yes you'll need a SWM to distribute that signal last mile on coax.  It's required because you have bidirectional communication between the STB's and the SWM.  2)  The drawing shows the basic TX/RX setup. For DirecTV, the SWM is crucial for the return path communication. If you are using our F-Lband-Tx/Rx, you will need the SWM after the receiver, and then split the coax output from the SWM to your 8 STBs. Let me know if that clears things up. However the most important aspect is still finding out what kind of dish it has; also if there are other units utilizing the same dish it might alter your design.  There are countless designs and styles of dishes from all the Satellite providers; so the number of LNB's is crucial; if the Dish has a built in SWM then you can't use our fiber gear.  Also single mode fiber is a necessity; multimode won't work; and SC/APC connectors are industry standard for RFoF products. For most installs, a 4ch or 6ch L-Band over fiber setup is usually the cleanest way to cover the satellite bands they actually need Thor Broadcast   12:47?PM (0 minutes ago)         to ROMAD             For most installs, a 4ch or 6ch L-Band over fiber setup is usually the cleanest way to cover the satellite bands they actually need   https://thorbroadcast.com/product/4-ch-l-band-satellite-over-single-fiber-extender-transmitter-and-8230.html

Answer:

For your application with the Inmarsat system, you'll need a setup that's similar to a cell phone antenna.  It supports duplex L-Band signals and is required to be bidirectional: here is our solution---  

For the bi-directional RF over fiber, you could possibly use 2 sets of F-L-band-TxRx over 2 singlemode fibers (one forward and one reverse). F-L-band-TxRx The frequency range is 45-2600mhz Again you would need to use TWO sets TX/RX sets to make it bi-directional and use 2 single mode fibers (has to be singlemode and use SC/APC connectors.  This is the link: https://thorbroadcast.com/product/l-band-over-fiber-tx-rx-basic-1-ch-kit.html You would also need an RF circulator, but that would be a good solution for this kind of application.  Not exactly a common application; and we don't have specific products for this type of Antenna; but what we proposed above should work, you can send me the specifications of that ANTENNA so I can double check, but my assumption is everything will be in the range required; you just need to make sure you have singlemode fiber. Please let me know if that would work for you.

Answer:

We have L-Band over Fiber TX/RX kits that should work for your 200m run. I recommend looking at the basic 1 channel kit you linked on the site. - F-LBAND-Tx/Rx   Tramsitter + Receiver

Since your system is a VSAT link (both uplink and downlink), you will need to use two L-Band RF over fiber links, working in opposite directions.

One link is for the downlink (satellite to equipment), and the second link is for the uplink (equipment to satellite).

Downlink path: Dish (LNB output) → L-Band TX → Fiber → L-Band RX → Modem / IRD

Uplink path: Modem / Modulator → L-Band TX → Fiber → L-Band RX → BUC → Dish

Important note on RF levels:

Our transmitter requires an input level between +10 to +30 dBmV.

In most cases:

• Uplink equipment outputs a higher RF level → you will need to add an attenuator before the TX

• Downlink signals from LNB are usually lower → you may need amplification after the RX

Simple rule: If signal is too high → attenuate before TX If signal is too low → amplify after RX

Each direction is independent and requires its own TX/RX path. The system transports RF transparently, so it will work with your existing VSAT equipment without protocol changes.
