The RF Over Fiber Optical Transmitter (4mW, 1310nm) is a high-performance solution designed to transport any RF signal over single-mode fiber with exceptional signal integrity and reliability. Supporting a wide frequency range of 45–1000 MHz, this unit enables seamless distribution of both analog and digital RF signals over long distances.
This transmitter directly converts incoming RF signals into optical signals, allowing all channels and services to be transported over a single fiber link. It is fully compatible with industry-standard RF over Glass (RFoG) systems and can operate with Thor Fiber receivers as well as third-party RF optical receivers.
This system supports virtually all RF modulation formats within the 45–1000 MHz range, including:
Example signal flow: HDMI sources enter a Thor modulator, the RF output feeds an RF optical transmitter, the fiber is split using PLC splitters, and multiple optical RF receivers convert the signal back to coax for TVs or local RF amplifiers.
Transmitter can be used with any or Thor Fiber optical RF receivers
Deliver dozens or hundreds of TV channels from a central headend to multiple buildings or rooms using fiber instead of coax.
Transport RF signals between buildings, campuses, or facilities without signal degradation over long distances.
Replace long coaxial cable runs with fiber to eliminate signal loss, noise, and grounding issues.
Distribute RF signals across large areas such as stadiums, racetracks, and event venues using fiber infrastructure.
Use QAM or ATSC modulators (such as Thor Broadcast modulators) to generate RF channels, then distribute them over fiber.
Deploy RF overlay services alongside data networks using passive optical splitters.
Transport RF feeds between headend equipment rooms, remote transmitter sites, or monitoring locations.
The transmitter works seamlessly with:
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.
The following CATV RF fiber optic transmitters are available. You can view all models here: CATV RF over Fiber Transmitters
Other available models: 8 mW, 16 mW, and 32 mW versions in both 1310 nm and 1550 nm wavelengths.
The Thor F-PLC passive fiber optic splitter with SC/APC connectors is an ideal accessory for CATV RF optical transmitters, allowing one optical signal to be split and routed to multiple locations over fiber. Available in 1x2 to 1x64 versions, it is perfect for RF over fiber distribution systems in hotels, campuses, apartment buildings, and other multi-location installations.

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

Yes, absolutely! We have great engineers and the capability to help you design and advise on the right equipment. Please check the application drawing below to see what we did for one of our customers

I checked the MUL-1310TX-1000 model number. It looks like it should include one more digit at the end (4, 8, 10, 12, or 16). This is an RF optical transmitter, and we can match an equivalent model from our Thor transmitters.
We also offer a complete fiber break system, PN : F-RF-BR which includes the transmitter (TX), receiver (RX), and an optical jumper. In this setup, it’s simply RF IN → fiber → RF OUT.

If you already have a working RX, we can just replace the failed TX. Alternatively, we can use a full replacement solution for this application.- PN F-RF-BR
Thor Fiber Optical Mini FTTH RF CATV CABLE TV Receiver with Dual Coax Output
The Thor F-RF-RX-MN-2 is a compact fiber optic to RF receiver that converts an incoming optical signal into electrical RF coax output. It is designed for systems carrying QAM, ATSC, DVB-T, and analog TV signals over fiber, then distributing them locally over standard 75-ohm coax networks.
