The Thor F-RF system is using for the transport and distribution of CATV RF signals over fiber optic cable. The transmitter converts the incoming RF signal (870 MHz) to an optical signal. This optical signal can be distributed to multiple end points with a coupler, or can be run more than 20 miles over a single-mode fiber optic cable. Often times a full-size rackmount receiver is not needed at the endpoints. The CATV mini receiver is used as a low-cost end point when rack equipment is not needed. The units have adjustable RF output level to drive multiple displays and ship with robust external power supplies. These units can also be used to make low-cost 'Fiber Breaks'. A Fiber Break allows RF to pass in only one direction and are essential for high-level data security. Without an RF return path, the system cannot be modified to extract data over an RF line.
• Optical Automatic Gate Control (AGC)
• Able to receive optical signals in either 1310nm or 1550nm bands.
• All working parameters controlled by a microprocessor
• Compact Form Factor
• Adjustable RF Output power
• No need to program parameters
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.

1550nm Externaly Modulated CATV RF Transmitter - Analog or QAM or ATSC CATV RF Over Fiber
1550nm DWDM Externally Modulated Optical Transmitter is an ideal solution for long-distance Analog RF or Digital QAM /ATSC from 45-1000Mhz over single mode fiber. It has much better dispersion and stability than a 1550nm internally modulated fiber optic transmitter, If your fiber distance exceeds more than 30km this is the perfect product for your application.
