Optical converters GI FibreMDU Twin and Quad were developed to connect LNB to GI FibreMDU optical output through PON network or directly through an optical attenuator.
Each of converters Twin and Quad receives an optical signal from GI FibreMDU LNB or PON network through a standard 3 mm cable that terminates in FC/PC connectors.
The optical signals are converted back into the original format of satellite IF and supplied to the output standard connector of type F and further to a satellite tuner, which makes the installation elementary.
Both Twin and Quad converters are fed from a satellite tuner.
