Studio-to-Transmitter (STL) Links -- MULTILINK product family
 |
The MULTILINK product family consists of multi-channel video links designed to transport from 1 to 31 high-quality video channels or digital data streams from the Headend to a remote site, typically to a broadband transmitter.
The standard band of operation is in the 2500 to 2686 MHz band, but other bands up to 28 GHz are available.
At the standard band the system can be used at line-of-sight distances of up to 50 Kilometers, depending on options such as output power and antenna size.
Each point-to-point link includes two parabolic dish antennas, one at the transmitter site and one at the receiver site, which provide a directional link with maximum rejection of external interference.
It is also possible to feed two receive sites from only one transmitter. This is done by splitting the transmitter power in two so that it can feed two different transmit antennas.
The MULTILINK transmitter accepts NTSC or PAL modulated video inputs and also digital carriers with any modulation. The standard input frequency range is 222 to 408 MHz. The link delivers the same frequency range at the receive end. Other input/output frequencies are available on request.
