Description

1550nm Direct Modulated  CATV Over Fiber RF Transmitter with AGC 2-16mW

F-RF-1550-TX-2mW  1550nm +2dBm output RF Transmitter
F-RF-1550-TX-4mW  1550nm +4dBm output RF Transmitter
F-RF-1550-TX-8mW  1550nm +8dBm output RF Transmitter
F-RF-1550-TX-16mW  1550nm +14dBm output RF Transmitter

1550nm - 2-16mW fiber optic transmitter for Television RF (Radio Frequencies) from 45-870 MHz. Operates on 1550 C-Band wavelength for compatibility with EDFA systems. 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

Features

  •  2-16 mW Optical Power Output from a C-Band laser compatible with EDFA amps
  •  Can be optically amplifed to high power levels for fan type distribution
  •  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:
I'm ISP Provider using fiber optic, I'm wanting to implement CATV. this device: "1550nm RF Over Fiber Tx 45-870 MHz 2 -16 mW" How many channels does it tune? Example, will I have to have one such device per channel? How much? How do I buy? I

Answer:
This is an RF over Fiber device, to which you can put a coaxial cable into the unit with all programs between 45-870Mhz; this unit will convert the RF signal to Fiber, and then on the receiver side, will convert all the programs from fiber back to Coaxial cable. You will also need a fiber optic receiver as well: https://thorbroadcast.com/product/rf-catv-mini-optical-receiver.html https://thorbroadcast.com/product/catv-rf-fiber-receiver-high-rf-power-rack-8230.html This product does not "tune" channels, this is a device to send CATV over fiber optic cable. Here are some questions from our engineer: CTAV Transmitter /Receiver it will take and convert all you CATV RF Analog or Digital channels from 45-1000mhz. What is fiber optic distance? Do you have single mode fiber? Is it point to point or point to the multipoint application? do you want to use it with the optical splitter?
