Signal OTH-2500CW A9810 optical transmitter converts satellite signals from a quad or quatro LNB and terrestrial TV and radio signals from an antenna array (DVB-T, DAB and FM radio signals combined with an RF combiner) into optical signals in Coarse Wavelength Division Multiplexing (CWDM) system that uses several wavelengths for carrying signals in one optical fiber. The built-in WDM multiplexer enables high-quality transmission in one transmission window using 4 wavelengths (VL: 1510 nm, HL:1530 nm, VH+Terr: 1550 nm, HH: 1570 nm).
At the SC/APC optical output, the OTH-2500CW A9810 transmitter provides 4x 3 dBm optical output power that allows for distribution of the signals to up to 32 optical receivers ORH-2500CW QUATRO A9812 located within a radius of 10 kilometers. The exact number of the receiving points and the maximum transmission range can be calculated using optical power budget methods.

The example below shows an SMATV optical installation built on the basis of Signal devices enabling the distribution of satellite TV signals, DVB-T digital terrestrial channels and DAB/FM radio signals.
