TELEVES 236903 Fibre IRS Quad Optical GTU MK3

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 4 RF outputs, with Terr. + SAT combination signal on each connector.

Important Installer Note:
The MK3 GTU’s MUST have a live fibre signal going into them before you connect the power supply!
