Key features
- For use in fiber optic cabling systems;
- One optical cable instead of 5- or 9-cable coaxial trunk;
- Single-mode technology;
- The use of a typical QUAD or QUATRO LNB allows for much easier dish alignment that in the case of an LNB with direct optical output;
- In contrast to competitive solutions, the optical transmitter does not have to be mounted close to the antenna dish;
- 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);
- Each receiving point with the QUATRO A9812 receiver/converter and a multiswitch or several multiswitches creates local RF distribution system (in total, the number of outlets/subscribers may exceed one thousand).
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.
