dCSS twin optical converter
FM/DAB/UHF/SAT
This accessory for systems equipped with an optical LNB, receives an optical TV signal (1100 nm-1650 nm) and restores the original RF signal. Provides 2 RF outputs, both mixed terrestrial and satellite TV signal. The converter supports Legacy, SCR I (EN50494), SRC II (EN50607) and SKY SCR modes.
MAIN FEATURES
- FC/PC optical connectors, F-type connectors for RF
- Status Indicator with green LED
- Plastic cover included, to protect the unit and the connectors
