Best Catv RF over Fiber Transmitter & Receiver, QAM over fiber

Q: 1) Do you guys have a solution for carrying coax over fiber? 2) Can it be used for satellite signals? Need just 1 satellite in and fiber out Transmitter and receiver

1) Yes, we have an entire catalog of products dedicated to that application. You can find them here: https://thorbroadcast.com/products/cable-tv-catv-rf-45-900mhz 2) Satellite TV is in the L-band range 850-2600 MHz; CATV is in the RF band 45-1000 MHz. Furthermore, L-band is much more complex. Are you trying to send this from the dish to your house? We send satellite dishes over fiber by converting each LNB on the dish to a wavelength, then use CWDM to mux. So, in order to choose the right equipment, we need to know how many LNBs your dish has. https://thorbroadcast.com/products/l-band-satellite-rf-45-3000mhz Basic HD dishes usually have 4 LNBs; some international dishes have a 5th sidecar LNB. https://thorbroadcast.com/product/4-ch-l-band-over-single-fiber-extender-45-3000mhz-cwdm.html This system is used for the basic dish. We also have a 6 LNB over single-fiber line: this is a link: https://thorbroadcast.com/product/6-ch-l-band-over-single-fiber-extender-54-3000mhz-cwdm.html Please note: you would need single-mode fiber and SC/APC connectors on both ends.

Q: do you have a number for what the minimum latency is for this transmitter/receiver pair from RF signal in to RF signal out, assuming no significant fiber length in between?

Our RF over fiber products are a direct analog RF-over-fiber system. There is no encoding, decoding, packetization, DSP buffering, or other digital signal processing in the RF signal path. The RF signal directly modulates the optical transmitter, and the receiver converts the optical signal directly back to RF. Therefore, with essentially no fiber length between the transmitter and receiver, the intrinsic TX-to-RX latency is extremely low—on the order of nanoseconds rather than milliseconds. As a practical specification, the electronics contribution should be well below 1 µs (

Description

RF over Fiber Tx - 2mW Output 45-870 MHz

1310nm - 2mW fiber optic transmitter for television RF (radio frequencies) from 45-870 MHz. 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 applications, 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. The 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.

The transmitter can be used with any Thor Fiber optical RF receiver.
