Which solution fits your project?
On coaxial cable satellite and TV signals weaken quickly with distance. With transport over fiber the RF signal is converted to light in the transmitter, carried on single-mode fiber and converted back to RF in the receiver; the same fiber can be split to many buildings or flats.

Frequently asked questions about TV and satellite distribution over fiber
How is a satellite signal carried over fiber?
The satellite IF (L-band) signal from the LNB is converted to light in the optical transmitter, carried on single-mode fiber and converted back to satellite IF in the receiver. A multiswitch or satellite receiver connects to the receiver output with ordinary coaxial cable.
Which fiber cable and connector are used?
These systems run on single-mode fiber. The BLANKOM BPF-41 and BPF-11 systems use SC/APC connections; for Televes products the connector type is given on the product page. APC and PC/UPC connectors must not be mated.
1310 nm or 1550 nm?
1310 nm transmitters are used on short and medium links with few splits. Because a 1550 nm signal can be amplified with an EDFA, it is preferred for long distances and networks with many subscribers.
How many subscribers can one fiber feed?
It depends on the optical budget: fiber, connector and splitter losses are subtracted from the transmitter output power, and the remaining level must be within the input range of the receiver. Send the distance and the number of subscribers and we will do the calculation with you.
I do not know the part number. How do I get a quotation?
Send the number of satellites, whether terrestrial signals are included, the fiber distance and the number of subscribers. We will work out the matching part numbers.

- If you know the code: model or reference number, quantity and delivery location are enough.
- If you do not: send the number of satellites, whether terrestrial signals are included, the fiber distance and the number of subscribers; we will suggest the system.
- If you have a specification or project drawing: send it and we will work out the matching part numbers.
